  • About This Answer

    Our income tax calculator calculates your federal, state and local taxes based on several key inputs: your household income, location, filing status and number of personal exemptions. Also, we separately calculate the federal income taxes you will owe in the 2020 - 2021 filing season based on the Trump Tax Plan.

    How Income Taxes Are Calculated

    • First, we calculate your adjusted gross income (AGI) by taking your total household income and reducing it by certain items such as contributions to your 401(k).
    • Next, from AGI we subtract exemptions and deductions (either itemized or standard) to get your taxable income. Exemptions can be claimed for each taxpayer as well as dependents such as one’s spouse or children.
    • Based on your filing status, your taxable income is then applied to the the tax brackets to calculate your federal income taxes owed for the year.
    • Your location will determine whether you owe local and / or state taxes.

Idaho has enacted several tax cuts in the past decade, lowering rates for top earners from a rate of 7.80% in 2011 down to the current rate of 6.50% for the 2021 tax year. Even with these tax cuts, that remains on the higher side of all the rates in the country. The Gem State also has lower-than-average sales taxes, with a statewide rate of 6% and a limited number of municipal sales taxes. Homeowners in Idaho likewise benefit from taxpayer-friendly policies, facing an average effective property tax rate of 0.63%. The national average is 1.07%.

A financial advisor in Idaho can help you understand how taxes fit into your overall financial goals. Financial advisors can also help with investing and financial plans, including retirement, homeownership, insurance and more, to make sure you are preparing for the future.

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 2021 tax year is $12,550 for single filers and $25,100 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.

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 19 that also charge a local sales tax in addition to the state 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. The resort cities with local sales taxes include Cascade, Crouch, Donnelly, Driggs, Hailey, Irwin, Kellogg, Ketchum, Lava Hot Springs, Mackay, McCall, Ponderay, Riggins, Salmon, Sandpoint, Stanley, Sun Valley, Swan Valley and Victor.

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 when compared to the rest of the country. On average, homeowners in the Gem State pay 0.63% of their home values in property taxes each year, which is a total of about $1,616 annually. Property taxes help pay for local services such as schools, law enforcement and libraries.

Property taxes are based on the market value of a home, but homeowners living in a primary residence may be eligible for a property tax exemption of up to $100,000. That means that a person living in a home worth that amount or less could pay no taxes whatsoever.

Idaho Gas Tax

Going for a drive in Sawtooth National Forest? Idaho collects a gas tax of 32 cents per gallon on both regular gasoline and diesel.

Idaho Cigarette Tax

Cigarettes in Idaho are taxed at a rate of 57 cents per pack of 20. The state has had the same rate since 2003 and it's one of the lowest cigarette taxes in the country. There is a separate tobacco tax on other tobacco products like cigars and snuff. That tax is equal to 40% of the wholesale price of the tobacco.

Idaho Alcohol Tax

Alcoholic beverages are taxed at varying rates in Idaho, depending on the type of beverage. The beer tax is relatively low, at just 15 cents per gallon (about 1.4 cents per beer). The state’s liquor tax is significantly higher: $11.28 per gallon, which is one of the highest in the U.S. However, it is still significantly lower than neighboring Washington State, which charges $14.27 per gallon. Therefore, it is common for Washington residents who live near the border to cross state lines and buy their booze in Idaho.

Idaho Estate Tax

There is no estate or inheritance tax in Idaho. Estates may still have to pay the federal estate tax, however.
