Debt, Taxes and Local Government
You'll be able to
- Explain the Article VII rules on uniform taxation, exemptions and local taxing power
- Apply Article VIII, Section 3 and its exceptions to decide whether a local project needs voter approval
- Summarize what City of Boise v. Frazier, Asson v. City of Burley and Greater Boise Auditorium District v. Frazier decided
- Describe the limits on city and county power under Articles XII and XVIII, including preemption by state general laws
Start here: the short version
- Article VII sets the tax rules. Property taxes must be "uniform upon the same class of subjects" within the area of the government levying them, the Legislature may grant exemptions, and it cannot levy local taxes itself. It can only give local governments the power to tax.
- Article VIII, Section 1 bars state debt unless voters approve it at a general election for a single, named project, with exceptions for ordinary operating expenses and money repaid within the fiscal year.
- Article VIII, Section 3 is the big one for local government. A county, city, school district or other subdivision cannot take on debt or liability beyond that year's income without two-thirds voter approval, unless it is an "ordinary and necessary" expense or falls under a listed revenue bond exception. Debt incurred in violation is void.
- The Idaho Supreme Court reads Section 3 strictly. In City of Boise v. Frazier (2006) it held that an airport parking garage was "ordinary" but not "necessary," so Boise needed a vote. "Necessary" means truly urgent.
- Articles XII and XVIII give cities and counties their police power and their elected officers. Local rules are valid only if they do not conflict with state general laws.
Every time a city council talks about a new fire station, a county weighs a jail expansion, or a school board decides whether to run a bond, the Idaho Constitution is in the room. Idaho's framers wrote some of the strictest public debt rules in the country, and the Idaho Supreme Court said so itself in 1912, saying Idaho's framers had "pronounced a more positive prohibition against excessive indebtedness than is to be found in any other constitution."
This lesson covers the money articles (VII, Finance and Revenue, and VIII, Public Indebtedness and Subsidies) and the local government articles (XII, Municipal Corporations, and XVIII, County Organization). It ends with a step-by-step test for whether a local project needs a public vote. Constitutional text is quoted from the official Idaho Constitution. This is civic education, not legal advice.
Article VII: how Idaho taxes
The basic tax power (Section 2)
Section 2 tells the Legislature to "provide such revenue as may be needful, by levying a tax by valuation, so that every person or corporation shall pay a tax in proportion to the value of his, her, or its property." It also allows a license tax on people and businesses and a per capita tax. The property tax is the tax the Constitution itself describes first.
Uniformity and exemptions (Sections 3, 4 and 5)
Section 3 says "property" will be "defined and classified by law." Section 4 exempts public property: that of the United States (unless Congress allows taxing it), the state, counties, cities, school districts, other municipal corporations and public libraries. Section 5 is the uniformity rule:
"All taxes shall be uniform upon the same class of subjects within the territorial limits, of the authority levying the tax, and shall be levied and collected under general laws, which shall prescribe such regulations as shall secure a just valuation for taxation of all property, real and personal: provided, that the legislature may allow such exemptions from taxation from time to time as shall seem necessary and just..."
Idaho Const. art. VII, sec. 5
Three practical points follow from that text.
- Uniform within a class. The Legislature sorts property into classes (Section 3), and taxes must be uniform within each class inside the taxing district's borders. A highway district's levy must apply the same way across that district.
- Exemptions are a legislative choice. The homeowner's exemption is the best-known example. Under Idaho Code 63-602G, the first $125,000 of a qualifying owner-occupied home's assessed market value, or 50 percent of it, whichever is less, is exempt.
- No double taxation. Section 5 also bans "duplicate taxation of property for the same purpose during the same year."
The Legislature cannot set your city's tax (Section 6)
Section 6 says the Legislature "shall not impose taxes for the purpose of any county, city, town, or other municipal corporation," but may give those governments "the power to assess and collect taxes for all purposes of such corporation." That is why local levies are set by local boards, within limits the Legislature writes into statute. The 3 percent annual cap on local property tax budget growth is one such statutory limit, covered in the three percent cap lesson.
Other Article VII rules worth knowing
- Section 9: the state property tax rate "for state purposes" may not exceed ten mills per dollar of assessed value unless voters approve a higher rate at a general election.
- Section 11: the Legislature may not authorize spending that exceeds the tax "then provided for by law" for the fiscal year, unless it also levies a tax to cover it. Idaho's balanced budget requirement starts here. War and insurrection are excepted.
- Section 15: counties must run "on a cash basis."
- Section 17: gasoline taxes and vehicle registration fees, after collection costs and refunds, "shall be used exclusively" for building, repairing, maintaining and policing public highways, and may not be diverted. When someone proposes using fuel tax money for something other than roads, this is the section to read.
Article VIII, Section 1: the state debt limit
Section 1 says the Legislature "shall not in any manner create any debt or debts, liability or liabilities" except in war, invasion or insurrection, unless:
- a law authorizes it "for some single object or work, to be distinctly specified therein";
- the law provides a way to pay interest and principal, "exclusive of loans," within twenty years; and
- the law is submitted to the people "at a general election" and receives "a majority of all the votes cast for or against it."
The section then lists exceptions. It "shall not apply to liabilities incurred for ordinary operating expenses, nor shall it apply to debts or liabilities that are repaid by the end of the fiscal year." Debts of independent public bodies that cannot levy taxes or obligate the state general fund are not state debts. And the section does not make illegal "those types of financial transactions that were legal on or before November 3, 1998."
Section 2 adds that the state may not lend its credit to private parties or become a stockholder in a corporation. It also creates the public school guarantee fund, which lets the state guarantee school district bonds without counting that guarantee as state debt.
Article VIII, Section 3: the local debt limit
This is the section that governs most local bond elections in Idaho. Here is its core:
"No county, city, board of education, or school district, or other subdivision of the state, shall incur any indebtedness, or liability, in any manner, or for any purpose, exceeding in that year, the income and revenue provided for it for such year, without the assent of two-thirds of the qualified electors thereof voting at an election to be held for that purpose..."
Idaho Const. art. VIII, sec. 3
What the section requires
- Who it covers: counties, cities, school boards and districts, and any "other subdivision of the state," which includes special districts.
- What triggers it: any "indebtedness, or liability" beyond that year's income and revenue. "Liability" is broader than a bond. The court said in 1912 that it is "a much more sweeping and comprehensive term."
- The vote: two-thirds of those voting, at an election held for that purpose.
- Repayment plan: an annual tax must be provided to pay interest and build a sinking fund to retire the principal "within thirty years."
- The penalty: "Any indebtedness or liability incurred contrary to this provision shall be void."
The exceptions written into the text
| Exception | What it covers | Vote needed |
|---|---|---|
| Ordinary and necessary expenses | "Ordinary and necessary expenses authorized by the general laws of the state" | None |
| City revenue bonds | Off-street parking, public recreation and air navigation facilities, paid only from user rates and charges | Two-thirds |
| Utility revenue bonds | Water systems, sewer systems, water and sewage treatment plants, and rehabilitating existing electric generating facilities, paid only from rates and charges | Simple majority |
| Port district revenue bonds | Port district powers, paid from non-property-tax revenue | None |
Article VIII also has separate sections (3A through 3E and 5) for pollution control bonds, port facilities, public hospitals, municipal electric systems, airports and nonrecourse industrial development bonds. Read the specific section before assuming a project fits.
"Ordinary and necessary": what the courts say
Most local fights are about the first exception. A government that wants to avoid an election argues the expense is "ordinary and necessary." Opponents argue it is not.
Example: the Boise airport parking garage
Boise wanted to build a five-level parking garage at its airport, on land then used for surface parking, and to pay for it through a long-term financing agreement without a public vote. The city asked a district court to confirm the deal under Idaho's judicial confirmation law. A Boise resident objected, and the case reached the Idaho Supreme Court as City of Boise v. Frazier, 143 Idaho 1, 137 P.3d 388, decided April 13, 2006.
Justice Burdick, writing for the majority and drawing on a commentary on the state constitution, explained that the intention of Section 3 "was to prevent local government entities from incurring debts without approval from the voters and a clear plan to retire those debts." The court then took the exception's two words separately.
- Ordinary: using a test from Hanson v. City of Idaho Falls, 92 Idaho 512 (1968), an expense is ordinary "if in the ordinary course of municipal business, or the maintenance of municipal property, it may be and is likely to become necessary." Airport parking qualified.
- Necessary: the court returned to the test from Dunbar v. Board of Commissioners of Canyon County, 5 Idaho 407 (1897): "there must exist a necessity for making the expenditure at or during such year." Expenditures qualify only if they are truly urgent.
The court said urgency "can result from a number of possible causes, such as threats to public safety, the need for repairs, maintenance, or preservation of existing property, or a legal obligation to make the expenditure without delay." Turning a flat lot into a five-floor garage was not a repair or any recognizable form of maintenance. The project was ordinary but not necessary, so Boise needed two-thirds voter approval. The court reversed the district court. Chief Justice Schroeder dissented without opinion, and a pro tem justice concurred only in the result.
Other cases that shape Section 3
- Feil v. City of Coeur d'Alene, 23 Idaho 32, 129 P. 643 (1912). The court described Idaho's clause as stricter than any other state's it had seen and distinguished "liability" from "indebtedness." Later courts still cite it.
- Asson v. City of Burley, 105 Idaho 432, 670 P.2d 839 (1983). Burley, Rupert, Heyburn, Idaho Falls and Bonners Ferry had signed 1976 agreements with the Washington Public Power Supply System to buy shares of two planned nuclear plants, without an election. When the projects were terminated, the cities remained on the hook for shares of about $2.25 billion in WPPSS bonds. The court held Section 3 applies no matter how the debt is repaid, rejected the "special fund" and "ordinary and necessary" arguments ("'ordinary' would not be one of them"), and declared the agreements void as to the cities.
- Greater Boise Auditorium District v. Frazier, Docket No. 43074 (Oct. 15, 2015). The auditorium district financed a convention center building through a lease with the city's urban renewal agency. The lease ran one year at a time, and the district could walk away by not renewing. The court held that because of its "genuine non-appropriation provisions," the lease did not create a liability beyond the current year's funds, and it satisfied Section 3.
Put those cases together and you have the modern rule. A multi-year commitment that binds the government to pay in future years needs a vote unless an exception applies. A truly year-to-year obligation the government can drop without penalty may not.
Myth: If a project is paid for with fees or user charges instead of property taxes, Article VIII, Section 3 does not apply.
Not in Idaho. In Asson v. City of Burley (1983) the court rejected the idea that the section covers only tax-funded debt and held that voter approval is required regardless of the repayment source. The Constitution does provide revenue bond routes, but each one is limited to listed kinds of facilities and still requires a vote: two-thirds for parking, recreation and airport facilities, a simple majority for water and sewer systems. Port districts are the main exception that needs no vote. A fee-funded project outside those categories is still subject to the two-thirds rule unless it is truly ordinary and necessary.
Judicial confirmation: asking a court first
Boise used a procedure that local governments still use often. Under the Judicial Confirmation Law, Idaho Code 7-1304, a governing body may petition the district court to determine whether a bond, obligation or related agreement is valid. Before filing, it must hold a public hearing and adopt a resolution or ordinance authorizing the petition. Anyone can file a written request to be notified by certified mail at least 14 days before such hearings, valid through December 31 of that year. Residents can appear in court and object, as happened in both Frazier cases. For a reporter or advocate, a notice of a judicial confirmation hearing is a signal that a government plans a large financial commitment without an election.
School districts, bonds and levies
School districts are named in Section 3, so school bonds need two-thirds. That is the supermajority behind the failed school bonds the court described in the ISEEO school funding case (see Lesson 7). Supplemental maintenance and operation levies are different: they are not debt, and under Idaho Code 33-802(3) a supplemental levy of a set amount for up to two years needs a simple majority. Under Idaho Code 34-106, these local elections generally may be held only on the third Tuesday in May or the Tuesday after the first Monday in November, apart from emergencies. The mechanics of school bonds and levies are covered in the levies and bonds lesson and in a separate school bond course now in the queue, so this lesson sticks to the constitutional rule.
No gifts of public credit
Article VIII, Section 4 and Article XII, Section 4 both bar local governments from lending their credit to, or becoming responsible for the debts of, private individuals, associations or corporations. Article XII, Section 4 also bars cities and counties from becoming stockholders in private companies. These clauses come up when a city is asked to guarantee a developer's loan or invest in a private venture. Article VIII, Section 5 allows narrow nonrecourse industrial development bonds that are paid only from the project and private sources, never from taxes.
Article XII: cities and their police power
Section 1 tells the Legislature to provide by "general laws" for incorporating, organizing and classifying cities. Section 2 is the local government's basic grant of power:
"Any county or incorporated city or town may make and enforce, within its limits, all such local police, sanitary and other regulations as are not in conflict with its charter or with the general laws."
Idaho Const. art. XII, sec. 2
"Police" here means the general power to protect public health, safety and welfare, not just law enforcement. It covers zoning, nuisance, animal control and much more. The limit is the last phrase: no conflict with "the general laws." In Envirosafe Services of Idaho, Inc. v. County of Owyhee, 112 Idaho 687, 735 P.2d 998 (1987), the Idaho Supreme Court held that a local rule can conflict with state law even without a direct contradiction, when the Legislature intended a state law to fully occupy a field. There, the state hazardous waste act preempted county regulation of hazardous waste.
Example: Magic Valley counties and dairy siting
In 2008, the prosecuting attorneys of Gooding, Lincoln, Jerome, Minidoka and Cassia counties asked the Attorney General whether state law preempts county regulation of large confined animal feeding operations. Attorney General Opinion 08-1 applied Article XII, Section 2 and Envirosafe. Its answer was split. Because state law expressly authorizes counties to regulate CAFO siting, county ordinances on location, such as setbacks or livestock density, were likely to be upheld. County rules that tried to impose water quality or waste management requirements on the ongoing operation of a CAFO were likely to be found in conflict with state law and preempted. AG opinions are not binding court rulings, but they are a good guide to how the state's lawyers read the Constitution.
Article XVIII: counties and county officers
Counties are creations of the state. Section 5 requires the Legislature to establish "a system of county governments which shall be uniform throughout the state." Section 11 says county officers "shall perform such duties as shall be prescribed by law."
Section 6 fixes the elected county offices. The Legislature must provide for electing county commissioners and, every four years, a sheriff, assessor, coroner and treasurer (who is also public administrator). The clerk of the district court is also ex officio auditor and recorder. Then comes a firm limit: "No other county offices shall be established." Section 6 also lets commissioners hire outside counsel when necessary and lets them set pay for deputies appointed by the other elected officers.
Section 10 sets a three-member board of county commissioners with staggered two and four year terms. Section 12 allows optional forms of county government, but only if county voters approve the change by majority, and they may revisit it no more often than every four years. For what commissioners can and cannot do day to day, see the county commissioner authority lesson.
How to: tell whether a local project needs a public vote
- Identify the government. Is it a county, city, school district or other subdivision? If so, Article VIII, Section 3 applies.
- Find the money plan. Get the staff report, financing term sheet or draft agreement. Ask: will the government owe payments in future fiscal years? A bond, a multi-year lease, an installment purchase or a guarantee can all be a "liability."
- Check the one-year escape. Can the government walk away at the end of each fiscal year without penalty, by not appropriating money? If the contract has genuine non-appropriation terms, Greater Boise Auditorium District v. Frazier (2015) says it may not be a multi-year liability. Read the default and damages clauses closely.
- Test "ordinary and necessary." Is the expense part of the ordinary course of business or maintenance? Then, is it truly urgent this year, because of a threat to public safety, a needed repair to existing property, or a legal obligation that cannot wait (City of Boise v. Frazier, 2006)? A new building or major expansion usually fails the "necessary" test.
- Check the revenue bond exceptions. Water, sewer and treatment plants: majority vote. City parking, recreation and air navigation facilities: two-thirds. Port districts: no vote. Then check Sections 3A to 3E and 5 for specialized categories.
- Watch for judicial confirmation. If the government schedules a public hearing on a resolution to file a petition under Idaho Code 7-1304, it is asking a court to bless the deal without an election. File a written request for notice and attend.
- Check the election date. If a vote is needed, it must fall on a date allowed by Idaho Code 34-106 (the May or November election), unless it is a true emergency.
- Ask the government's attorney in writing. Request the legal opinion or bond counsel memo explaining why no vote is needed, or which exception applies. Many of these are public records.
If you report on this
Do not write that a project "needs a vote" or "can skip a vote" without naming the provision and exception. The legal question is specific: is this a liability beyond the year's revenue under Article VIII, Section 3, and if so, which exception applies? Ask officials directly whether the expense is claimed as "ordinary and necessary," and why it is urgent this year. Look for judicial confirmation petitions in district court filings and hearing notices. When a bond fails with 60 percent or more voting yes, explain that the Constitution sets the two-thirds threshold, not a statute or local rule, so changing it would require a constitutional amendment (Lesson 9). For property tax stories, separate the constitutional rules (uniformity, exemptions by law, local levying power) from statutory limits like the 3 percent budget cap.

Check yourself
1. Under Article VIII, Section 3, what vote does a city usually need to take on debt beyond that year's income and revenue?
Section 3 requires the assent of two-thirds of the qualified electors voting, unless an exception applies.
2. In City of Boise v. Frazier (2006), why did Boise's airport parking garage need a vote?
The court found the garage ordinary but not necessary. Necessary expenses must be truly urgent, such as public safety threats, needed repairs or legal obligations.
3. Which revenue bonds need only a simple majority vote under Article VIII, Section 3?
The text allows water systems, sewer systems and treatment plants to be financed by revenue bonds with majority approval. Parking, recreation and air navigation need two-thirds.
4. What did Asson v. City of Burley (1983) hold?
The court held Section 3 applies no matter how the debt is repaid and found the WPPSS agreements void as to the cities because no election was held.
5. Under Article XII, Section 2, a city ordinance is valid only if it is not in conflict with what?
Cities and counties may make local police, sanitary and other regulations that are not in conflict with their charter or with the general laws.
6. What does Article VII, Section 17 require of gasoline taxes and vehicle registration fees?
Section 17 says the proceeds, after collection costs and refunds, shall be used exclusively for highway construction, repair, maintenance and traffic supervision and related debt.
