The Idaho Sales Tax Calculator helps you quickly determine the sales tax on a purchase in any city or county in Idaho. You can calculate sales tax by adding it to a pre-tax amount or removing it from a total amount.
When adding sales tax:
- Tax Amount = Pre-Tax Amount × Tax Rate
- Total Amount = Pre-Tax Amount + Tax Amount
When removing sales tax:
- Pre-Tax Amount = Total Amount ÷ (1 + Tax Rate)
- Tax Amount = Total Amount – Pre-Tax Amount
Idaho has a state sales tax rate of 6.00%, with additional local taxes that vary by city and county. This calculator combines both state and local tax rates for accurate calculations.
Adding Sales Tax Example
Let’s say you want to calculate sales tax on a $100 product in Sun Valley with a total tax rate of 8.00% (6.00% state + 2.00% local):
Pre-Tax Amount = $100
Tax Rate = 8.00% or 0.08
Calculate the tax amount:
Tax Amount = $100 × 0.08 = $8.00
Calculate the total amount:
Total Amount = $100 + $8.00 = $108.00
Removing Sales Tax Example
Now, let’s say you have a total amount of $108.00 and want to calculate the pre-tax amount and tax in Sun Valley:
Total Amount = $108.00
Tax Rate = 8.00% or 0.08
Calculate the pre-tax amount:
Pre-Tax Amount = $108.00 ÷ (1 + 0.08) = $108.00 ÷ 1.08 = $100.00
Calculate the tax amount:
Tax Amount = $108.00 – $100.00 = $8.00
Different Local Tax Example
In Boise, there is no local sales tax, so the total tax rate is 6.00% (state tax only). Let’s calculate tax on a $100 product:
Pre-Tax Amount = $100
Tax Rate = 6.00% or 0.06
Calculate the tax amount:
Tax Amount = $100 × 0.06 = $6.00
Calculate the total amount:
Total Amount = $100 + $6.00 = $106.00

Understanding Idaho Sales Tax
What is Idaho Sales Tax?
Idaho sales tax is a consumption tax imposed by the state and local governments on the sale of goods and certain services. The state rate is 6.00%, with local jurisdictions adding additional taxes that vary by city and resort area.
Local Tax Variations
Local tax rates in Idaho can range from 0% to 3%, depending on the city and resort area. Most cities in Idaho do not have a local sales tax, but resort communities like Sun Valley, McCall, and Island Park have implemented local option taxes to fund tourism-related infrastructure and services.
Tax Collection
Sales tax in Idaho is collected by sellers at the point of sale and remitted to the Idaho State Tax Commission. Sellers must register with the state and obtain a sales tax permit before collecting tax.
Use Tax
Idaho use tax applies when sales tax has not been paid on taxable items purchased outside the state for use in Idaho. The use tax rate is the same as the sales tax rate that would have applied if the purchase was made within the state.
Business Registration
Businesses selling taxable goods or services in Idaho must register for a sales tax permit with the Idaho State Tax Commission. Registration can be done online through the Idaho State Tax Commission website.
Filing Requirements
Sales tax returns in Idaho are typically filed monthly, quarterly, or annually, depending on the business’s tax liability. Filing is done through the Idaho State Tax Commission’s online system, and payments are due by the 20th of the month following the reporting period.
Idaho Sales Tax for Businesses
Nexus Requirements
Businesses must collect Idaho sales tax if they have nexus in the state. Nexus can be established through physical presence, economic activity, or other connections. Idaho follows economic nexus rules, requiring out-of-state sellers to collect tax if they have more than $100,000 in sales into the state in the previous calendar year.
Marketplace Facilitators
Marketplace facilitators like Amazon and eBay are required to collect and remit sales tax on behalf of third-party sellers selling into Idaho. This applies to marketplace facilitators with more than $100,000 in sales into the state.
Exemption Certificates
Businesses purchasing items for resale can provide exemption certificates to sellers to avoid paying sales tax. Idaho has a specific form (Form ST-101) that must be completed and provided to the seller at the time of purchase.
Shipping and Handling
In Idaho, shipping and handling charges are generally taxable if they are part of the sale of tangible personal property. If the charges are separately stated and related to transportation services, they may be exempt.
Penalties and Interest
Idaho imposes penalties for late filing and late payment of sales tax. The penalty is 5% of the tax due per month, up to 25% of the tax due, plus interest at the rate of 0.5% per month. Failure to file or pay can result in additional penalties and legal action.
Tax Calculation Services
Given the complexity of Idaho’s sales tax system with different local tax rates in resort areas, many businesses use automated tax calculation services to ensure accurate collection and remittance of sales tax.
