Module 6: Budgets, Taxation & Fiscal Duty

The County Budget Process

Idaho county commissioners are stewards of public money. Their first responsibility is ensuring that budgets are prepared carefully, presented transparently, and adopted according to law. The budget cycle is not merely bookkeeping, it is the primary vehicle through which commissioners exercise fiscal duty and remain accountable to the public.

Idaho Code § 31-1601 et seq. (the County Budget Law) establishes the budget process. The county fiscal year begins on the first day of October of each year (Idaho Code § 31-1601), and the statutory timeline runs backward from that date. It typically unfolds as follows:

Step 1: Budget Preparation (May)

The county auditor is the county's budget officer (Idaho Code § 31-1602(1)) and prepares a preliminary budget for the commissioners' consideration. On or before the first Monday in May, the budget officer must notify each county official in charge of an office, department, service, agency or institution, in writing, to file an itemized estimate on or before the third Monday in May. The estimate shows the probable revenues other than taxation and the expenditures the office requires for the fiscal year, with a brief explanatory statement. An official who fails or refuses to file on time may be penalized $10 to $50 by order of the board, deducted from the next salary warrant (Idaho Code § 31-1602(6)). Using those estimates the budget officer prepares a suggested budget showing all contemplated expenditures and the sources of revenue to pay for them (Idaho Code § 31-1603), for the fiscal year that begins October 1.¹

During preparation, commissioners should:

• Review department requests critically, are they necessary, or inflated?
• Ensure the tentative budget complies with revenue limits (particularly the 3% cap discussed below)
• Request detailed justifications for significant increases
• Verify that projected revenues are conservative and realistic

Step 2: Tentative Budget and Published Notice (August)

The budget officer submits the suggested budget to the board on or before the first Monday in August. The commissioners convene to consider it in detail, make any alterations allowable by law that they deem advisable, and agree on a tentative amount to be appropriated to each office, department, service, agency or institution (Idaho Code § 31-1604(1)). Not later than the third week in August, the budget officer must cause notice to be published setting out the anticipated revenue from property taxes, the total of revenues from other sources, and the amount proposed to be appropriated to each office or department in at least two classifications (salaries or salaries and benefits, and detail of other expenses), together with the amounts spent in each of the two previous fiscal years. The notice must also state the time and place of the budget hearing, and it is published in a newspaper as prescribed in Idaho Code § 31-819.²

This is not a pro forma step. The public notice requirement exists so citizens can review the tentative budget, compare it to prior years, and identify concerns before the hearing. Commissioners should ensure that the notice is accurate and informative and that the suggested budget is made available to anyone who requests it.

Step 3: Public Hearing (on or before the Tuesday after the first Monday in September)

On or before the Tuesday following the first Monday in September, the board must meet at the time and place designated in the notice (Idaho Code § 31-1605). Any taxpayer may appear and be heard upon any part of the tentative budget. The hearing may be continued from day to day but must be concluded by the second Monday in September. Any officer or employee in charge of an office or department may be called before the board while the estimates for that office are under consideration and examined by the board or any taxpayer about past and estimated expenditures. The hearing is not optional.³

At the hearing, commissioners must:

• Present the tentative budget and explain its rationale
• Allow members of the public to testify, object, or propose amendments
• Consider all objections and comments in good faith
• Answer questions about revenue sources, spending priorities, and budgetary constraints

The public hearing is where fiscal duty becomes real. If citizens object to spending or raise concerns about revenue, commissioners should address those concerns substantively, not dismissively.

Step 4: Final Budget and Adoption (September)

Upon the conclusion of the hearing, the commissioners fix and determine the amount of the budget. The final budget may in no event be greater than the amount of the tentative budget, and it may not include an amount to be raised from property taxes greater than the amount advertised. The board adopts the budget by resolution and enters the resolution in the official minutes (Idaho Code § 31-1605). The adopted budget must specify the fund or funds against which warrants will be issued, and the expenditures authorized against any fund may not exceed the estimated nonproperty-tax revenue, plus balances, plus the revenue from taxation within the limits of chapter 8 of title 63 (Idaho Code § 31-1605). At the time the law provides, the board then fixes the levies needed to raise the budgeted expenditures, less other revenue.⁴

During the year the commissioners may adjust the adopted budget to reflect unscheduled revenue, grants or donations from federal, state or local governments or private sources, provided there is no increase in anticipated property taxes, and the annual budget procedure must be complied with as nearly as practicable before the budget is adjusted (Idaho Code § 31-1605). No salary may be increased during the year after the final budget is adopted without a resolution of the board entered in the minutes, and for road and bridge appropriations other than salaries and benefits, a lawful transfer may be made by resolution at a regular or special meeting (Idaho Code § 31-1606).

Timeline & Deadlines

The statutory timeline is firm:

• First Monday in May: Budget officer notifies offices to file estimates; estimates due the third Monday in May
• First Monday in August: Suggested budget submitted to the board; board agrees on tentative appropriations
• Third week of August: Notice of tentative budget and hearing published
• On or before the Tuesday after the first Monday in September: Budget hearing; concluded by the second Monday in September; final budget adopted by resolution
• October 1: Fiscal year begins

Commissioners should build in buffer time. Statutory dates are fixed, and the final budget cannot be rushed past the hearing deadline. I found no provision in the County Budget Law that authorizes an interim budget; Idaho Code § 31-1606 provides that the budget as finally adopted constitutes the appropriations for the fiscal year and that each county official or employee is limited in expenditures and liabilities to the amounts appropriated. Appropriations lapse at the end of the fiscal year, except for incomplete improvements, though accounts may remain open until the first Monday in November to pay claims incurred before the year ended (Idaho Code § 31-1609).

Spending Limits, Claims and Warrants

Once the budget is adopted, it controls spending. The adopted estimates constitute the county's appropriations for the fiscal year, and every county official and employee is limited to the appropriated amounts in making expenditures and incurring liabilities (Idaho Code § 31-1606). Expenditures, liabilities or warrants in excess of the appropriations are not a liability of the county. The official who made them is personally liable, and the county auditor may not issue a warrant, and the commissioners may not approve a claim, for an expenditure over the appropriation except on a court order or for an emergency under the statute. Any county officer who creates such a liability, or any commissioner or auditor who approves such a claim or issues such a warrant, is liable to the county for the amount, recoverable from the official and the official's sureties, and the prosecuting attorney is directed to bring the action (Idaho Code § 31-1607).

The rules for paying bills are in chapter 15 of Title 31. The board examines, settles and allows accounts legally chargeable against the county and orders warrants drawn on the county treasurer (Idaho Code § 31-810). The board may not hear or consider a claim unless it is accompanied by a receipt or documentation giving all items, certified by the authorized county official that the amount is justly due or the services were rendered, and no claim may be paid if it was not presented within a year from the date the bill was generated (Idaho Code § 31-1501). The board must require its clerk to furnish a list of all bills allowed, with the name of each payee, amount and fund, must review and certify the list, and the treasurer may pay no warrant that does not correspond with the list (Idaho Code § 31-1502). The board may not contract debts or liabilities except in pursuance of law, and may not allow the account of a county officer who neglects a duty or is liable on an official bond (Idaho Code § 31-1503). If a claim is greater than what is justly due, the board may allow it in part (Idaho Code § 31-1505), and judicial review of a final board decision is governed by chapter 52, title 67 (Idaho Code § 31-1506).

The board may not transfer money from one fund to another, or divert money in a fund to other uses, except as the law expressly permits, and any transfer must be ordered by a resolution entered in the board's records and filed with the auditor and treasurer (Idaho Code § 31-1508). A warrant is an order drawn by the board directing the treasurer to pay a specified amount; a registered warrant is a warrant drawn on a fund with insufficient money to pay it, which is logged by the treasurer and auditor and paid in the order of presentation (Idaho Code § 31-1510). Warrants payable on demand are jointly issued and signed by the auditor and treasurer (Idaho Code § 31-1511).

Two safety valves exist. First, the board may make a "general reserve appropriation" not exceeding five percent (5%) of the current expense budget, and in the event of an unforeseen contingency may appropriate from it only by unanimous vote of the board (Idaho Code § 31-1605). Second, in an emergency of the kinds the statute lists (for example fire, flood, explosion, storm, epidemic, riot, or the investigation and prosecution of a crime punishable by death or life imprisonment), the board may by a resolution adopted by unanimous vote of the commissioners, stating the facts constituting the emergency and entered in the minutes, make the expenditures needed (Idaho Code § 31-1608). The budget officer reports to the board on or before the last day of January, April, July and October on expenditures and liabilities against each appropriation, and calls attention to any possible deficit or excessive expenditure (Idaho Code § 31-1611).

Property Tax Mechanics in Idaho

Counties depend primarily on property tax revenue. Understanding how property tax actually works, from assessment to collection, is essential for fiscal literacy and for recognizing when tax policy is not functioning as advertised.

The Assessment Process (Idaho Code Title 63)

Property tax begins with assessment. Each county assessor appraises property at market value for assessment purposes as of 12:01 a.m. on January 1 of the year in which the taxes are levied (Idaho Code § 63-205).⁵ Taxable value is that market value less the exemptions the law allows, such as:

• Homestead exemption: For an owner-occupied primary residence, the first $125,000 of market value or fifty percent (50%) of market value, whichever is less, is exempt from property taxation (Idaho Code § 63-602G), subject to the conditions in that section. The dollar amount is set by statute and may change.
• Agricultural land: Land actively devoted to agriculture that meets the qualifications of Idaho Code § 63-604 is eligible for appraisal, assessment and taxation as agricultural property, on a basis other than ordinary market value.⁶
• Property tax reduction for qualifying homeowners: Idaho Code §§ 63-701 through 63-710 provide a property tax reduction for qualifying claimants (including, among others, those age sixty-five or older), on claims filed on forms prescribed by the State Tax Commission. This is a reduction program, not an exemption.
• Exemptions for government, charitable, and religious property: These properties are exempt from taxation to the extent and under the conditions the exemption statutes provide (Idaho Code § 63-602 and the sections it references).

Exemptions, not a gap between assessed and market value, are what make taxable value lower than market value. Because Idaho requires assessment at market value, rising property values do raise the tax base. The property tax budget limit in Idaho Code § 63-802 is stated in dollars of property tax revenue, so when values rise, the levy rate generally falls rather than revenue automatically growing without limit.

The Levy Rate

Once values are set, the board fixes the levy needed to raise the budgeted amount of property tax, within the budget limit in Idaho Code § 63-802 (Idaho Code §§ 31-811 and 31-1605). The levy rate is the property tax to be raised divided by taxable value.

The formula is straightforward:

County Property Tax Revenue = Total Taxable Value × Levy Rate

For example, if a county has $500 million in total taxable value and sets a levy rate of 0.01 ($0.01 per dollar of value, or 10 mills), the county collects $5 million.

What Drives Property Tax Revenue Growth

Here is a critical point: under Idaho Code § 63-802, the dollar amount of property tax revenue a taxing district may budget is limited by a formula, and three factors determine how much it can grow:

1. The growth factor: up to 3% over the highest property tax budget certified in any of the three preceding tax years
2. Additions for new construction and annexation, calculated with the preliminary levy rate
3. Voter-approved increases and the levy categories that the statute does not count (for example, voter-approved bonds), and recovery of forgone increases

Because the limit is stated in dollars of property tax revenue, a rise in property values does not by itself let a taxing district collect more. If values rise faster than the allowed dollar increase, the levy rate falls. The county's revenue from any single property can still rise or fall, because each owner's share depends on how that property's value changes compared with the rest of the tax base.

Commissioners should understand that the property tax system includes deliberate brakes on revenue growth. These brakes are features, not bugs. They reflect the public policy, set in statute, of limiting arbitrary tax increases on property owners.

The 3% Budget Growth Limit (Idaho Code § 63-802)

Idaho Code § 63-802 is perhaps the most important revenue statute affecting county budgets. It limits the dollar amount of property tax revenue that a taxing district may certify for its annual budget. The limit is commonly called the "3% cap," but the formula contains several additions and exceptions, which are described below.⁷

The Basic Rule: Highest Prior Budget Plus Up to 3%

The statute provides that a taxing district may not certify a budget request for property tax revenues above the highest dollar amount of property taxes it certified for its annual budget in any one of the three tax years preceding the current tax year, increased by a growth factor of not more than three percent (3%), plus the additions for new construction and annexation described below (Idaho Code § 63-802(1)(a)(i)). The taxing district decides how much of the 3% it needs and calculates a preliminary levy rate from that percentage. Commissioners therefore cannot simply vote to raise property tax revenue beyond the formula.

A board of county commissioners may not set a levy that exceeds the limit, and the State Tax Commission may not approve one, unless a majority of the district's electors voting on the question approve it at an election, and such voter approval lasts for not more than two years (Idaho Code § 63-802(3)). A voter-approved increase that becomes part of the permanent base requires approval by sixty-six and two-thirds percent (66 2/3%) or more of the voters voting on the question (Idaho Code § 63-802(1)(h)).

New Construction

New construction adds to the allowed budget, but it is part of the formula rather than outside it. The preliminary levy rate is multiplied by the value shown on the new construction roll, and the product is added to the allowed amount (Idaho Code § 63-802(1)(a)(i)). For fire protection districts and ambulance service districts, the previous year's levy rate is used for this calculation.⁸ This addition counts toward the eight percent (8%) total ceiling on the formula increase (fifteen percent (15%) for fire and ambulance districts).

For example, if a developer builds a $2 million warehouse and the county's preliminary levy rate is 0.01, about $20,000 of new allowable budget capacity results from that warehouse, before the 8% ceiling is applied. Because the capacity arises only from new construction, it does not require raising the rate on existing property. This creates an incentive to promote growth.

However, new growth also brings demands for new infrastructure and services, and the added budget capacity may not match the cost of serving that growth. Commissioners should compare the two before assuming that growth pays for itself.

Annexation

The preliminary levy rate is also multiplied by ninety percent (90%) of the value of annexation during the previous calendar year, as certified by the State Tax Commission for operating property of public utilities and by the county assessor, and the result is added to the allowed amount.⁹ Annexation therefore adds to the annexing district's allowed budget, within the same eight percent (8%) ceiling.

The Eight Percent Ceiling

Except as the statute provides, the total budget increase calculated under the formula (the 3% growth factor plus the new construction and annexation additions) must not exceed eight percent (8%) (Idaho Code § 63-802(1)(a)(ii)).¹⁰ Items that are not subject to that ceiling include increases resulting from the termination, de-annexation or plan modification of an urban renewal revenue allocation area, or the withdrawal of certain taxing districts from one, and certain annexations by fire protection or library districts as the statute lists. Revenue from levies for voter-approved bonds, override levies and supplemental levies, and certain other levies is not counted in the property tax budget at all (Idaho Code § 63-802(4)).

Whether the ceiling comes into play depends on the district's growth in new construction and annexation in a given year, so fast-growing districts are more likely to reach it than slow-growing ones.

"Forgone" Increases

One of the least understood features of Idaho tax law is the "forgone increase." A nonschool taxing district that certifies less than the maximum allowable increase in the dollar amount of property taxes in a year may reserve the right to recover the forgone increase in a later year by adopting a resolution specifying the dollar amount being reserved. The district must give notice of its intent and hold a public hearing, and the resolution to reserve the right is adopted at the district's annual budget hearing (Idaho Code § 63-802(1)(f)). To recover it later, the district must again give notice, hold a public hearing, and certify by resolution the amount and the specific purpose for which it is being budgeted (Idaho Code § 63-802(1)(e)).¹¹ For fire protection districts and ambulance service districts the statute applies these forgone-increase provisions only to years before property tax year 2026.

Recovery is rate-limited. If the forgone increase is budgeted for maintenance and operations, the district's budget may increase by no more than one percent (1%) per year from recovering it. If it is budgeted for a capital project (as the statute defines that term, including construction or renovation of public facilities, roads, bridges, water, sewer and broadband systems, and equipment with a useful life of ten years or more), recovery may not exceed three percent (3%) of the district's budget for the year in which it is budgeted (Idaho Code § 63-802(1)(e)(ii) and (iii)). A forgone amount therefore cannot be recaptured in a single large step, and the amount recovered for a capital project is deducted from the forgone balance in the year it is budgeted.

This mechanism is lawful but often debated. It allows a district to smooth revenue over time and recapture capacity that it did not use in prior years, within the statutory limits. Commissioners who rely on it should explain the purpose to taxpayers at the budget hearing, as the statute requires.

Liberty Callout: Reading Past the 3% Figure
The 3% limit is often described as a rigid constraint on county budgets. In practice the formula also allows additions for new construction and annexation (within an 8% ceiling), recovery of forgone increases (within yearly rate limits), voter-approved increases, and the exclusion of voter-approved bond levies and certain other levies. Citizens should look at the certified dollar amount of the budget, not just the 3% figure, to see how revenue actually changes from year to year.

Urban Renewal Revenue Allocation

Urban renewal financing also affects county budgets. When an urban renewal plan uses revenue allocation financing, the county commissioners calculate the levy rates for each taxing district in the revenue allocation area using the taxable value shown on the base assessment roll rather than the current value (Idaho Code § 50-2908(1)), with the exceptions that section lists. The property tax revenue produced by the growth above the base is placed in a special fund for the urban renewal agency (Idaho Code § 50-2908). For the budget limit, 63-802 treats the end or modification of a revenue allocation area as a listed exception to the eight percent ceiling.¹²

The money collected from property owners in the area does not disappear. It is directed to an agency whose board is appointed, not elected, as described below.

The Budget Hearing & Public Accountability

The statutory requirement for a public budget hearing (Idaho Code § 31-1605) is not ceremonial. It is the primary mechanism through which commissioners remain accountable to the citizens they serve.

Notice Requirements

The budget officer must cause notice to be published not later than the third week in August. The notice states the anticipated property tax revenue, the revenue from other sources, the amount proposed to be appropriated to each office or department (with the prior two years' expenditures), and the time and place of the budget hearing, which is to be on or before the Tuesday following the first Monday in September (Idaho Code § 31-1604(2)). It is published in a newspaper as prescribed in Idaho Code § 31-819. The statute does not set a minimum number of days between publication and hearing beyond those dates.¹³

Best practices for commissioners:

• Publish the full tentative budget (or a substantial summary) alongside the notice, not just a bare notice of hearing.
• Include the website URL where the full budget can be downloaded.
• Provide department-by-department breakdowns so citizens can see where money is being spent.
• Compare the tentative budget to the prior year's budget and explain significant changes.

These steps are not required by statute, but they fulfill the spirit of fiscal accountability.

The Hearing Itself

The hearing is held at the time and place designated in the notice, and any taxpayer may appear and be heard upon any part of the tentative budget (Idaho Code § 31-1605). The hearing is a meeting of the board and must also comply with the open meeting law. If citizens object to a proposed tax increase, commissioners should listen, respond, and consider amendments.

The statute limits what the board can do at the end of the hearing: the final budget may not be greater than the tentative budget, and it may not include more property tax revenue than the amount advertised (Idaho Code § 31-1605). If the board wants to raise either figure, it cannot do so without a new tentative budget and notice. If substantial public opposition exists, commissioners should either:

• Amend the budget and hold a new hearing, or
• Adopt the budget as proposed but document the public concerns in the meeting minutes and explain why commissioners believe the budget is necessary despite the objections.

Transparency and responsiveness are the foundation of fiscal legitimacy. A budget adopted in the face of documented, substantial public opposition, without amendment or genuine consideration, will be viewed (rightly) as unresponsive and may erode public trust.

Constitutional Accountability

Idaho's Constitution, Article VII, section 2 requires the legislature to levy a tax by valuation so that every person pays in proportion to the value of his or her property, and section 5 requires that all taxes be uniform upon the same class of subjects within the territorial limits of the authority levying the tax. The budget hearing is where citizens can raise questions: Is this tax increase necessary? Is it used for legitimate county purposes? Is the burden distributed fairly?

Commissioners are not mere budget administrators; they hold public money in trust and must be prepared to defend the budget, not just its compliance with the property tax budget limit, but the wisdom and necessity of the budget itself.

Revenue Sources Beyond Property Tax

Property tax is a major county revenue source, but counties generate revenue from other sources as well. Commissioners should understand all of them and ensure they are used transparently.

Highway Distribution Account (Idaho Code § 40-709)

Idaho Code § 40-709 apportions money appropriated from the highway distribution account to local units of government. After a small amount for the Local Highway Technical Assistance Council, thirty percent (30%) goes to cities and the remainder goes to counties by formula: ten percent (10%) divided equally among all counties, forty-five percent (45%) in proportion to motor vehicle registration collections, and forty-five percent (45%) in proportion to miles of improved highways in the county highway system. Where a county contains highway districts, the money is further divided among the county and the districts. The state controller remits the apportionment by January 25, April 25, July 25 and October 25 each year.¹⁴

Highway distribution money is intended for highway purposes, so it does not directly fund the sheriff, courts, or administration. By covering road costs it can reduce the property tax needed for roads, which has an indirect effect on county budget capacity. The specific use restrictions for county receipts should be confirmed in Title 40 before relying on them.

State Revenue Sharing

The state distributes portions of certain state tax revenues back to counties. For example, Idaho Code § 63-3638 directs the State Tax Commission to distribute a set amount each year from sales tax collections to the 44 counties, part in equal shares and part by population, along with other amounts for particular purposes. These amounts are set in statute and can change, so the current text of § 63-3638 should be checked.

Federal Grants & Payments

Counties receive federal funding for specific programs: law enforcement grants, public health grants, emergency management funding, and others. However, federal grants come with strings attached: compliance with federal regulations, matching fund requirements, and reporting obligations.

A critical point for commissioners: federal grant money is not "free money." It often obligates counties to implement federal policies, hire additional staff, or incur future costs after federal funding ends. Before accepting federal grants, commissioners should carefully analyze the true cost, including the indirect costs of compliance and the risk that federal funding will be withdrawn, leaving the county to sustain programs with its own revenue.

Fees for Services

Counties generate revenue from numerous user fees: recording fees, permit fees, court costs, jail booking fees, and many others. These fees are often set by statute or resolution and should be reviewed periodically to ensure they reflect the actual cost of providing the service.

Liquor Fund Distributions

Money in the state liquor account is distributed under Idaho Code § 23-404. Part of the balance is appropriated to the several counties, including for deposit in the district court fund, and part is distributed to counties based on misdemeanor and infraction filings by city law enforcement officers. Counties do not operate liquor stores. The amounts vary with sales and with changes in state law.

Debt Limitations & Circumvention Mechanisms

Idaho's Constitution places strict limits on county debt to prevent excessive borrowing. However, modern financing mechanisms have created workarounds that commissioners should understand.

Constitutional Debt Limit (Idaho Constitution Art. VIII, § 3)

Idaho Constitution, Article VIII, section 3 provides that no county, city, board of education, school district or other subdivision of the state may incur any indebtedness or liability, in any manner or for any purpose, exceeding in that year the income and revenue provided for it for that year, without the assent of two-thirds of the qualified electors voting at an election held for that purpose. Before or when the debt is incurred, provision must be made for the collection of an annual tax sufficient to pay the interest as it falls due and to create a sinking fund to pay the principal within thirty years. Indebtedness or liability incurred contrary to the section is void. The section does not apply to the ordinary and necessary expenses authorized by the general laws of the state.¹⁵

This is a strict limit on a county's obligations in a year. For example, a county with $20 million of income and revenue provided for the year cannot incur liabilities for that year that exceed $20 million without a two-thirds vote of the electors, except for ordinary and necessary expenses. The limit is designed to prevent counties from mortgaging the future for immediate spending.

Lease-Purchase Agreements

Counties sometimes use lease-purchase agreements to acquire property, equipment or facilities. These agreements are generally structured so that the county's obligation is limited to payments from annually appropriated funds, which is the basis on which they are treated as outside the constitutional limit. This guide could not confirm a specific Idaho Code section or Idaho Supreme Court decision on that treatment, and the result in a given case depends on how the agreement is written.¹⁶

A lease-purchase is similar in economic effect to borrowing: the county commits to payments over a term, and the total cost of the payments typically exceeds the initial purchase price. Commissioners should review the agreement carefully and be transparent about its total cost.

The constitutional question is whether a particular lease-purchase creates an indebtedness or liability within the meaning of Article VIII, section 3. Reasonable people disagree, and the outcome depends on the structure of the agreement and on court decisions that should be checked before a transaction.

Commissioners should approach lease-purchases cautiously and be transparent about their true cost and effect on the county's long-term obligations.

Certificates of Participation (COPs)

Another financing tool is the certificate of participation (COP). A COP is a certificate representing the right to receive payments from a lease agreement. COPs are issued to raise immediate capital, and investors receive their return from lease payments.

Like lease-purchases, COPs raise the question of whether they are circumventing the constitutional debt limit. They allow counties to acquire assets without voter approval or traditional bonding, but they also commit the county to long-term payment obligations.

Constitutional Tension: Debt Limit Circumvention
Article VIII, section 3 limits a county's liabilities in a year to the income and revenue provided for that year unless two-thirds of the voters approve. Lease-purchases and certificates of participation can produce a financing result similar to borrowing, and whether they trigger the limit depends on how they are structured and on court decisions. Commissioners should be aware of this question and should be careful about commitments that extend over many years.

Urban Renewal & Tax Increment Financing (Idaho Code § 50-2001 et seq.)

Urban renewal areas and tax increment financing (called revenue allocation financing in the Idaho Code) are among the most significant and most debated tools in local fiscal governance. Understanding how they work is essential for commissioners because they affect tax revenue, involve substantial public money, and raise real questions about accountability and taxation.

How Urban Renewal Works

An urban renewal area is a geographically defined area in a municipality (which the Idaho Urban Renewal Law defines to include any incorporated city or town, or county, Idaho Code § 50-2018(2)) that has been found to be deteriorated or deteriorating as the law defines those terms. An independent public body, the urban renewal agency (Idaho Code § 50-2006), carries out the plan. The agency's board of commissioners is appointed, not elected: unless the statute provides otherwise, the mayor appoints three to nine commissioners with the advice and consent of the local governing body (Idaho Code § 50-2006(2)(a)). An agency created after July 1, 2011 may not transact business until a majority of the voters in a citywide or countywide election authorize it (Idaho Code § 50-2006(1)(b)).

The critical mechanism of urban renewal is tax increment financing. Here is how it works:

1. Baseline established: When a revenue allocation area is created, the taxable value of the property in it is recorded on the base assessment roll (Idaho Code § 50-2908(1)).
2. Future growth allocated: Levy rates for each taxing district are calculated using the base roll value, and the property tax revenue produced by growth above the base is allocated to a special fund of the urban renewal agency rather than to the taxing districts, subject to the exceptions in Idaho Code § 50-2908(1)(a) through (g).
3. Agency uses the allocated revenue: The agency uses the revenue to pay for the costs of urban renewal projects in the area and may pledge it to repay bonds or other borrowing, which may be issued for a maximum period of twenty years (Idaho Code § 50-2909(1)).
4. Allocation ends: When the plan budget estimates that all financial obligations have been provided for, or the bonds and other obligations are paid, the allocation of revenues ceases, and any excess money in the special fund is distributed to the affected taxing districts in the same proportion as the most recent distribution (Idaho Code § 50-2909(4)).

In principle, urban renewal is intended to encourage redevelopment of deteriorated areas by making the growth in property tax revenue within the area available to fund public improvements.

The Revenue Allocation Question

However, revenue allocation financing sets aside property tax revenue from growth in the area for the urban renewal agency, for as long as the allocation lasts. During that time a taxing district whose levy is subject to the allocation, such as a school district, does not receive the revenue from growth above the base roll value for that levy. A school district, for example, serving a redeveloped area would not receive additional revenue from those allocated levies for new residents, except as the statute's exceptions provide.

The size of the revenue allocated to urban renewal agencies varies by area and year. Commissioners can ask the county auditor for the amounts allocated in their county. This guide did not verify any statewide total for earlier years.

The Governance Problem: Taxation Without Representation

The urban renewal agency's board is not elected. Its commissioners are appointed by the mayor with the advice and consent of the local governing body (Idaho Code § 50-2006(2)(a)). Yet the agency controls property tax revenue allocated to it from property owners and businesses within the area.

This structure raises a policy question: Is it consistent with democratic accountability for an appointed board to control and spend public tax revenue? The Legislature has addressed part of this by requiring a public hearing for new plans (Idaho Code § 50-2906) and voter authorization for agencies created after July 1, 2011.

The Idaho Constitution, Article VII, section 5, provides that all taxes shall be uniform upon the same class of subjects within the territorial limits of the authority levying the tax. Some critics argue that urban renewal complicates this principle because property owners within an area experience different tax treatment than owners outside it, and they have no direct voice in the board that controls the allocated revenue. This guide did not locate an Idaho Supreme Court holding that decides that argument.

Liberty Callout: Taxation Without Representation
Revenue allocation financing allows property tax revenue to go to an appointed board that the voters do not directly elect. Property owners and residents in urban renewal areas pay taxes but do not elect the board deciding how the allocated revenue is spent. Critics argue this structure is at odds with the principle that taxation requires representation and that public money should be controlled by elected officials. Commissioners should carefully consider whether urban renewal districts genuinely serve the public interest or whether they have become instruments of developer subsidy and erosion of democratic control over taxation.

Ending an Urban Renewal Allocation

When the revenue allocation ends, the revenue formerly allocated to the urban renewal agency returns to the affected taxing districts (Idaho Code § 50-2909(4)), and the Idaho Code lists the end of an area's allocation as a budget-limit exception for the affected districts (Idaho Code § 63-802(1)(a)(ii)). Idaho Code § 50-2903 is the definitions section and does not provide a termination mechanism.

Commissioners should periodically review whether active urban renewal areas in their county still serve a legitimate purpose and whether the plan budget shows that the obligations have been provided for, in which case the allocation should end (Idaho Code § 50-2909(4)).

Constitutional Questions

Urban renewal raises two questions that critics have raised about constitutional principles:

1. Representation: Does allowing an appointed agency to control allocated property tax revenue conflict with the principle that taxation requires representation?
2. Uniformity: Does allocating property tax revenue away from schools and other taxing districts conflict with the constitutional requirement of uniform taxation (Article VII, section 5)?

These are legitimate concerns that commissioners should take seriously when considering new urban renewal areas or extending existing ones. This guide did not verify the current state of Idaho case law on them.

Constitutional Tension: Urban Renewal Revenue Diversion
Idaho's Constitution requires uniform taxation (Article VII, section 5), and revenue allocation financing sets aside property tax revenue for an appointed agency for years. Critics see a conflict between these principles. Whatever the courts may decide, commissioners should ensure that any urban renewal area genuinely serves a public purpose, and does not merely subsidize private development at the expense of schools and county services.

Constitutional Tensions & Fiscal Duty

County commissioners operate within a constitutional and statutory framework that has tensions of its own. Understanding these tensions is part of fiscal duty.

The Tension Between Growth and Restraint

Idaho's Constitution (Article VIII, Section 3) limits a county's liabilities in a year to its income and revenue for that year unless two-thirds of the voters approve. Lease-purchases and certificates of participation can produce a financing result similar to borrowing, which raises the question of how the limit applies to them.

Similarly, the 3% growth factor in Idaho Code § 63-802 is meant to restrain tax growth, but the additions for new construction and annexation, forgone increases, voter-approved increases, and the excluded levies mean property tax budgets can grow by more than 3% in a year, within the 8% ceiling. The limit works as intended when commissioners use it as a real constraint.

The Tension Between Representation and Efficiency

Urban renewal areas are created because their sponsors believe they can encourage redevelopment of deteriorated areas. However, this requires creating an appointed agency that controls allocated tax revenue. That trades direct democratic representation for administrative efficiency, and raises the question whether the trade-off is justified.

Federal Funding and Local Autonomy

Counties are increasingly dependent on federal grants for law enforcement, public health, and emergency management. However, federal funding comes with federal regulatory requirements. This creates a tension between local autonomy (the power of elected commissioners to govern their counties) and the requirements imposed by federal funders.

Commissioners should be thoughtful about federal funding and ensure that the regulatory strings attached do not exceed the value of the funding or compromise the county's ability to govern itself.

Liberty Callout: Federal Grants as a Trojan Horse
Federal grants seem like free money, and they are attractive to commissioners facing tight budgets. However, federal funding creates regulatory obligations that may exceed county authority and create long-term dependency. When a county accepts federal grant funding for a program, the county often becomes obligated to continue that program or incur federal penalties, even if federal funding is later withdrawn. Moreover, federal regulations may require policies that conflict with local priorities or constitutional principles. Commissioners should carefully analyze the true cost of federal funding, including indirect costs of compliance, before accepting grants. Sometimes declining federal funding and retaining local autonomy is the wiser course.
