Idaho homeowners 65 and older whose 2026 income comes in at $40,030 or less can apply to cut their 2027 property taxes starting Jan. 1. The Idaho State Tax Commission says the Property Tax Reduction program could lower a bill by $250 to $1,500 on a home and up to one acre of land. The application window closes April 15, 2027.
Nothing has to be filed yet, which makes this a planning question for the next ten weeks. The income test looks back at 2026, so the numbers that decide the result are being set now. The Tax Commission’s program page says applicants must apply and qualify every year.
What counts toward the $40,030 income limit
The limit is not simply gross income. The Tax Commission says the test is that the applicant’s total 2026 income, after deducting medical expenses, was $40,030 or less. A homeowner whose income is above that line before medical bills can still land under it afterward.
Medical costs carry real weight in this program. Applicants must submit a Medical Expense Statement along with the application, and the commission publishes a separate income-brackets sheet that matches income to the size of the reduction. Anyone near the cutoff has a reason to total up 2026 medical costs before January.

The income ceiling has risen modestly. A September roundup of state senior tax programs listed the 2026 limit at $39,130 after allowable medical deductions. The $40,030 figure for 2027 is $900 higher, an increase of about 2.3%.
The same roundup noted that the April 15 deadline for the 2026 program has passed and that applicants have to apply and qualify again each year. A homeowner who received a reduction on the 2026 bill therefore cannot assume it carries over, and a household whose income rose past the old limit may now sit under the new one.
Who can apply besides people 65 and older
Age 65 is only one of several ways in. The commission lists applicants who were 65 or older, blind, widowed or disabled, along with former prisoners of war or hostages and children under 18 who have lost a parent. People who lived in a care facility or nursing home in 2026, or live in one in 2027, may also qualify.
The home has to meet its own tests. The applicant must have owned and lived in an Idaho home as a primary residence before April 15, 2027, and the property needs a current homeowner’s exemption. Mobile homes are eligible, and the benefit does not reduce solid waste, irrigation or other fees that appear on the same bill.
That separate exemption is the piece many owners overlook. The Idaho homeowner’s exemption exempts 50% of the value of a home and up to one acre of land, with a maximum of $125,000, and it is applied for through the county assessor’s office. Once approved, it lasts until ownership changes or the home stops being the owner’s primary residence.
A senior who bought a home recently, or moved, may not have one on file. Because the reduction program requires a current homeowner’s exemption, the first call belongs to the county assessor, not the Tax Commission. The commission’s help line is (208) 334-7736 for questions about either program.
How to apply, and when the money arrives
The commission accepts applications online through its TAP portal, through the county assessor’s office, or on a paper form mailed to the assessor. The online and county routes are the same program, so applicants can pick whichever is easier. The commission’s guide and income-brackets sheet are the documents to review before applying.
The paperwork has a short list of named forms. The commission points applicants to the 2027 program guide, form EBR00135, and the income-brackets sheet, EPB00168, and says the Medical Expense Statement, form EFO00119, is required. Homes held in a trust, limited partnership, LLC or corporation add an affidavit.
Applicants who prefer paper can mail the form to the county assessor, and the commission notes that its paper application is still labeled with a 2026 title. Anyone unsure which version to use can ask the assessor or call the commission at (208) 334-7736 before sending it.
An approved reduction appears on the December 2027 property tax bill. That timing means the savings arrive months after the January to April window closes.
The other Idaho programs that run on the same calendar
Two related programs use similar dates. The commission’s Property Tax Deferral allows qualified homeowners to postpone taxes on a home and up to one acre of land. For 2027 the income ceiling is $63,400, applications run from Jan. 1 to Sept. 7, 2027, and the deferred taxes must be repaid with interest.
The state also lists a separate benefit for veterans rated 100% service-connected disabled, described on the Tax Commission’s homeowner programs page alongside the reduction, deferral and homeowner’s exemption. The commission says that benefit has no income limit. Each program has to be applied for on its own.
The difference between the reduction and the deferral is the one that matters for a household near the limits. A reduction lowers the bill, while a deferral only delays it and adds interest. For an Idaho homeowner who expects to land under $40,030, the open question is whether the county assessor already has the homeowner’s exemption on file before January.
Will the Idaho property tax reduction application go in on January 1?
Idaho tests 2026 income after medical costs against the $40,030 limit, requires a Medical Expense Statement with the application and wants a current homeowner’s exemption on file. The window closes April 15, 2027, and the whole process has to be repeated every year.
The Senior Property Tax & Home-Cost Relief Kit lays out the 5 kinds of property-tax relief and the circuit-breaker credit that includes renters, so an Idaho reduction can be compared with deferrals and credits in other programs. Its application log and renewal calendar is built for filings that come back every year.
