Following Property Taxes Year-Round: Calendar, Records and Checks

You'll be able to

  • Follow the Idaho property tax year from January 1 to the June 20 second-half payment
  • Name the key public records at each stage and who holds them
  • Read an L-2 certification and check it against taxable value and the maximum budget
  • Use the Tax Commission's statewide reports and dashboards to put local numbers in context
  • Request records under the Idaho Public Records Act with the right deadlines in mind

Public attention to property tax usually arrives in two bursts: June, when notices land and people are angry, and late November, when bills land and people are angry again. By then the decisions are made. The time to show up is in between, while boards can still change course. This lesson turns the module into a routine.

The records

From the assessor

  • Total market and taxable value by category (residential, commercial, agricultural, timber, mining, utilities) for at least five years.
  • The new construction roll by district, and annexation value.
  • The five-year appraisal plan and this year's appraisal areas.
  • Counts: homeowner exemptions, circuit breaker and veterans claims, appeals filed and won.
  • The county abstract: the auditor's summary of values by category that goes to the Tax Commission for equalization under 63-109.

From each taxing district

  • The L-2 form for the last five years. Under Tax Commission Rule 803, it is presumed to be "a true and correct representation" of the budget the district adopted, so it is the official number.
  • Forgone reserve and recovery resolutions, and the published budget hearing notice.
  • The debt schedule for every bond and levy. Under 63-803(5), districts must give the tax collector the expiration date of each voter-approved bond and levy, so those dates should exist.
  • For school districts, School District Facilities Fund amounts and how each dollar was applied.

From the county clerk and treasurer

  • The levy table: each district's certified dollars, taxable value, levy rate, and total rate by tax code area.
  • BOE minutes and docket, exemption approvals, and any 63-602NN contracts.
  • Delinquency counts and amounts after December 20 and June 20.

Request records under the Idaho Public Records Act. Idaho Code 74-103 requires an agency to grant or deny a resident's request within three working days, or within ten working days if it notifies you in writing that it needs more time. The request must say clearly that it is a public records request. Jeff's Idaho FOIA / Public Records Letter Generator drafts the letter, and the Idaho Open-Meetings Compliance Tracker helps you log each budget hearing's notice and agenda.

Checking a district's numbers

Example: the Sage Hollow Fire District's L-2

You obtain the invented district's 2026 L-2 and the Tax Commission's worksheet:

  • Certified property tax: $1,860,000
  • Net taxable value from the county: $1,240,000,000
  • Maximum non-exempt budget per the worksheet: $1,905,000
  • 2025 certified property tax: $1,790,000
  • Forgone resolution adopted: none

Check 1, the rate. $1,860,000 / $1,240,000,000 = 0.001500000. Does the county levy table say 0.001500000? If not, ask why. A difference can be legitimate (an urban renewal base, a multi-county split under 63-803(3)) or an error.

Check 2, the change. ($1,860,000 - $1,790,000) / $1,790,000 = 3.9 percent. Fire districts now have a 15 percent ceiling on growth under HB 959 (2026), per the Tax Commission, so 3.9 percent is within limits, but it is more than 3 percent. Ask how much came from new construction.

Check 3, the forgone. $1,905,000 - $1,860,000 = $45,000 not levied. With no resolution, that year's forgone increase cannot be recovered later. And under HB 959, fire and ambulance districts can no longer reserve new forgone amounts after 2025 anyway, though older reserved balances can still be recovered within the 1 percent and 3 percent limits.

Check 4, the bill. On a home with $300,000 taxable: $300,000 x 0.0015 = $450.00 for this district.

Checklist

  • Every number has a year and a source document.
  • Dollars and rates are given side by side.
  • Value changes are split from budget changes (value effect and rate effect).
  • State credits and facilities money are identified, with the year's amounts.
  • Exempt levies (voter-approved) are separated from capped ones.
  • Urban renewal increment is accounted for in any rate comparison.
  • Each district I describe as raising or cutting taxes has had a chance to respond with its numbers in front of it.
  • Comparisons with other places name the measure, year, source and comparison group.

Common mix-ups

  • Claim: The Tax Commission sets local levies. What the evidence shows: Districts set budgets, county commissioners set levies, and the Tax Commission reviews and approves them to make sure limits are not exceeded.
  • Claim: The budget in the newspaper notice is what the district will levy. What the evidence shows: The notice is a proposal. The L-2 filed in September is the certified amount. Cite the L-2.
  • Claim: If a district misses a deadline, nothing happens. What the evidence shows: Missing the April 30 hearing-date notice under 63-802A costs a district that year's 3 percent, new construction and annexation increases and any forgone recovery.

Reporting angle

  • Make a standing spreadsheet: one row per district per year, with certified dollars, taxable value, rate, maximum budget, forgone balance and exempt levies. Update it every October.
  • Pick one "typical home" each year, the county's median homestead, and publish its full bill history by district.
  • Each December, read the Tax Commission's new statewide report the week it comes out and localize its biggest finding.
  • Keep a source list of who answers the phone at the assessor's, clerk's and treasurer's offices and at the Tax Commission's property tax bureau. These are the people who keep you from publishing a wrong number.

Pictures, Numbers and Infographics

Idaho levied about $2.3 billion in property tax for 2025. The mix inside that total moved: city and county levies rose every year since 2021, while school levies fell as the state used facility funds to reduce them.

By the numbers

  • $2.502 billion: Idaho property tax budgets for 2025 before any state relief. School facility levy reductions brought the amount levied to $2.286 billion, and homeowner tax relief brought the final cost to taxpayers to $2.174 billion. Idaho State Tax Commission, Market Values and Property Taxes for 2025
  • $328.0 million: total legislative property tax relief in 2025 ($215.2 million in school district facility funds and $112.8 million in homeowner tax relief), up from $246.2 million in 2024 and $314.1 million in 2023. Idaho State Tax Commission, 2025
  • $593.3 million to $404.4 million: school property taxes levied statewide, 2021 to 2025. Over the same years city levies rose from $571.2 million to $705.0 million and county levies from $560.1 million to $682.4 million. Idaho State Tax Commission, 2025 (Table 7)
  • 8.4 percent: statewide growth in taxable value from 2024 to 2025, after 5.7 percent the year before. From 2021 to 2022 it was 43.7 percent. Idaho State Tax Commission, 2025
  • 44.3 percent: share of all 2025 property taxes, after relief, paid by owner-occupied homes. In 2022 it was 51 percent. Idaho State Tax Commission, 2025
  • 0.580 percent: statewide average property tax rate in 2025, based on levied amounts: 0.680 percent in urban areas and 0.423 percent in rural areas. Rates ran from 1.670 percent in Craigmont City to 0.145 percent in one rural part of Idaho County. Idaho State Tax Commission, 2025 Average Property Tax Rates
  • $163,594: half of the Idaho taxing districts that levied property tax in 2025 levied less than this. Only 45 districts levied more than $10 million each. Idaho State Tax Commission, 2025
Property tax levied by type of government Millions of dollars, statewide 2021 2025 County $560.1 $682.4 City $571.2 $705.0 School $593.3 $404.4 Highway $129.5 $154.2 All other $258.6 $340.4
