Taxes in Idaho: Features and Advantages

Main Taxes in the State of Idaho

Income Tax:

Since 2023, Idaho has introduced a single flat personal income tax rate of 5.8%. The tax applies to wages, business income, capital gains, and rental income. The state allows standard deductions and tax credits for children, education, and medical expenses. Retirees may benefit from *certain exemptions* on pensions and social security payments.

Sales Tax:

The base sales tax rate in Idaho is 6%. Local governments are not allowed to add surcharges, so the rate is uniform across the state. The tax applies to most sales of goods, commercial property rentals, and certain services (such as entertainment and lodging). Groceries are taxed at the standard rate, but buyers may receive a tax credit to offset this.

Determining the taxable base and applying the correct sales tax rate can be complex and requires professional expertise and knowledge of state law. Our company provides services for obtaining a Sales Tax Certificate, as well as preparing and filing Sales and Use Tax Returns. We advise business owners on registration, calculation, and reporting.

Property Tax:

Property tax in Idaho is levied at the county and municipal level and varies depending on location and property type. The average effective rate is about 0.63% of market value, below the national average. The state also offers a homeowner’s exemption, reducing the taxable value of a primary residence by up to 50% (subject to a set limit).

Business Taxes:

C‑corporations are taxed at a rate of 5.8% – the same as the personal income tax rate. S‑corporations and LLCs are taxed on a pass‑through basis, with profits taxed at the owner level. An Annual Report is mandatory for all companies registered in Idaho. The filing deadline is annually by the last day of the registration anniversary month. Businesses must also file tangible personal property returns if asset values exceed $250,000 (2025 limit).

Our company provides services for registering LLCs and corporations in Idaho, monitoring Annual Report deadlines, and calculating and filing corporate taxes.

Excise Taxes:

The state levies excise taxes on alcohol, tobacco, gasoline, car rentals, lodging services, and monthly (annual) fees for commercial vehicle registration.
