City Sales Taxes

Some Idaho resort cities have a local sales tax in addition to the state sales tax. These local sales taxes are sometimes also referred to as local “option” taxes because the taxes are decided by the voters in the community affected. 

Resort cities have a choice in what’s taxed and can include everything that’s subject to the state sales tax. Some, but not all, choose to limit the local sales tax to lodging, alcohol by the drink, and restaurant food.

Cities with local sales taxes

Use Tax Basics Guide

Use tax is a tax on goods you use or store in Idaho that haven’t been properly taxed. You owe Idaho use tax if you didn’t pay sales tax on goods that aren’t exempt. The use tax rate is the same as the sales tax rate.

You probably owe use tax if you’re an individual or if you operate a business that:

  • Shops online or buys items from sellers that don’t collect Idaho sales tax
  • Buys from out-of-state sellers that don’t collect sales tax
  • Buys items in another country and brings them into Idaho
  • Takes items out of sales inventory to give away or use 
  • Uses untaxed goods in a taxable activity
  • Gets a refund of Idaho tax paid on fuels
  • Uses goods when performing a nontaxable service
  • Is a multi-level marketing business or buys from multi-level sellers
  • Provides free samples or giveaways
  • Repairs goods covered under an optional warranty or maintenance agreement
  • Brings equipment, supplies or vehicles into Idaho for permanent use
  • Brings business assets into Idaho for temporary use
  • Does contracting work on real property in Idaho

Calculating use tax due

You owe use tax based on the taxable price of an item. The Idaho use tax rate is the same as the Idaho sales tax rate.

The amount of use tax you owe is based on a recent sales price of the item, or when the item first becomes taxable. Without proof of a recent purchase price, you owe tax on the item based on its fair market value.

Also see the Sales and Use Taxes Basics Guide for what the taxable purchase price includes, what it doesn’t, and how discounts and rebates affect the taxable purchase price. 

Recordkeeping

Individuals

Individuals can use the worksheet format in pdf Form 850-U – Self-Assessed Use Tax Return and Instructions, to track their untaxed purchases.

Businesses and organizations

Many businesses keep a use-tax accrual account to post tax due when they post purchases on which tax is due. Some businesses keep a use tax worksheet that lists purchases and inventory withdrawals on which use tax is due.

Whatever method your business uses, you must keep the records at least four years if you have a use tax permit. Businesses that don’t have a permit must keep records for at least seven years.

How to Report, File and Pay Use Tax

Individuals

Businesses and organizations

Retailers and wholesalers

Retailers and wholesalers must report and pay use tax they owe on their regularly filed sales tax return.

Not retailer or wholesaler

Businesses that aren’t retailers or wholesalers report and pay use tax according to the following scenarios:

  • You owe use tax most months: Get a use tax permit. See tax.idaho.gov/ibr for more information about registering for an account. There’s no cost to obtain a permit.
  • You make large-dollar purchases infrequently: Use pdf Form 850-U – Self-Assessed Use Tax Return and Instructions, to pay use tax by the 20th of the month after you buy the item.
  • You make small, frequent purchases: Report and pay the use tax yearly on pdf Form 41Idaho Corporation Business Tax Return, or pdf Form 41SIdaho S Corporation Income Tax Return.

Getting Use Tax Credit for Another State’s Sales Tax

You don’t owe Idaho use tax if you correctly paid another U.S. state’s sales tax* and its rate was equal to or greater than Idaho’s. You owe the difference if the other U.S. state’s sales tax rate is less than Idaho’s.

* A “U.S. state’s sales tax” includes local sales taxes such as city or county local option taxes, in any U.S. state, commonwealth, possession, territory or the District of Columbia.
