How to Collect Sales Tax Legally in Idaho

Collecting sales tax properly is essential for business compliance in Idaho. Follow these steps to ensure your business handles sales tax correctly.

Register for a Sales Tax Permit

• Register with Idaho State Tax Commission: Before collecting sales tax, your business must obtain a sales tax permit by registering online with the Idaho State Tax Commission.
• Provide Business Information: During registration, you will submit details such as your business structure, location, and estimated sales.

Understand Taxable Sales

• Identify Taxable Goods and Services: Most tangible personal property sales are taxable. Some services may also be taxable depending on Idaho law.
• Stay Updated: As of 2026, review the Idaho State Tax Commission website regularly for updates on taxable items and exemptions.

Collect and Calculate Sales Tax

• Apply the Correct Rate: Idaho has a statewide sales tax rate of 6%. Local jurisdictions may add additional taxes, so verify the total rate for your business location.
• Use Automation Tools: Implement sales tax software or point-of-sale systems that automatically calculate and apply the correct tax rate based on the customer’s location.

Recordkeeping and Reporting

• Maintain Detailed Records: Keep thorough records of all sales, tax collected, and exemptions claimed to support your tax filings and audits.
• File Sales Tax Returns: Submit your sales tax returns and remit collected taxes to the Idaho State Tax Commission according to your assigned filing frequency (monthly, quarterly, or annually).

Additional Operational Considerations

• Employee Training: Train staff on how to handle sales tax during transactions to avoid errors.
• Compliance Reviews: Periodically review your sales tax processes and compliance status to reduce the risk of penalties.
• Sales Tax Nexus: If your business sells to customers in other states, understand nexus rules to determine if you must collect sales tax outside Idaho.
