Idaho Income Taxes

In 2025, Idaho removed its progressive income tax system and brackets in favor of a flat 5.3% income tax, which applies to all income above $2,500 ($5,000 for joint filers).

Taxpayers in Idaho pay taxes based on total income, which includes wages, salaries, self-employment income, rental income, royalties and various forms of interest income. Social Security is not taxed in Idaho, nor is interest from U.S. Government Obligations.

Filers in Idaho can claim itemized deductions or the standard deduction, whichever is greater. The standard deduction is equal to the federal standard deduction, which for the 2025 tax year is $15,750 for single filers and $31,500 for joint filers. The personal exemption was eliminated starting in the 2019 tax year, just as they were with federal income taxes.

Idaho Tax Credits

Some taxpayers in Idaho may also be able to claim tax credits to lower their tax bill. Idaho credits include the credit for income taxes paid to other states, credits for charitable contributions and live organ donations and the grocery credit (which is available to low-income taxpayers to offset Idaho’s sales tax on food). Since the 2018 tax year, Idaho also has a nonrefundable child tax credit of $205 for each qualifying child. The child tax credit sunsets Jan. 1, 2026. 

Idaho Capital Gains Tax

Capital gains are taxed as regular income in Idaho, and subject to the personal income tax rates outlined above. However, certain types of capital gains qualify for a deduction. Real property that is held for at least one year is eligible for a deduction of 60% of the net capital income (that is the net gain after expenses).

Tangible property (i.e. not stocks, easements or other intangible goods) used in a revenue-producing enterprise and held for at least 12 months is also eligible for the 60% deduction. Farmers and ranchers may be able to claim the deduction for the sale of horses or cattle sold after 12 or more months, and any timber held for at least 24 months is eligible.

Intangible property, like stocks or bonds, does not qualify for the capital gains deduction under any circumstances.

Idaho Sales Tax

Idaho’s state sales tax is 6%. This is the rate you will be charged in almost the entire state, with a few exceptions. There are nine counties that include local governments that may charge their own sales tax. These local sales taxes are often called “local option taxes.” The cities with a local sales tax can decide which purchases are subject to the tax and at what rates. For example, it’s common for these cities to charge an additional tax on lodging, alcohol and restaurant food sales.

Idaho Local Sales Tax

Idaho sales tax applies to the sale, rental or lease of most goods and some services. Temporary lodging (30 days or less) is taxed. Food is taxed in Idaho, though low-income taxpayers may be eligible for a tax credit to offset the cost of sales taxes paid on food purchases. Prescription drugs, however, are exempt from sales taxes.

Idaho Property Tax

Idaho has relatively low property taxes compared to the rest of the country. A typical homeowner in the Gem State pays 0.43% of their home value in property taxes each year, which is a total of about $1,912 annually. Property taxes help pay for local services such as schools, law enforcement and libraries.

Property taxes are based on the assessed value of a home, but homeowners living in a primary residence may be eligible for a property tax exemption of up to 50% of the home value or up to one acre of land ($125,000 maximum).
