How to file a sales tax return in Idaho Idaho: Sales Tax Handbook


How to file your sales taxes in Idaho

Once your business has an Idaho sales tax license and begins to make sales, you are required to start collecting sales taxes on behalf of the Idaho government and filing regular sales tax returns. This page will help you understand the basics of your tax collection and filing responsibilities.

How To Collect Sales Tax In Idaho

If the seller has an in-state location in the state of Idaho, they are legally required to collect sales tax at the tax rate of the area where the buyer is located, as Idaho is a destination based sales tax state.

If the seller's location is out of state, then the collection of sales tax is still done in the same way. The seller would still be required to charge the local rate of sales tax from the buyer's location, so long as the seller has tax nexus in the state. It must be noted that while Idaho's statewide sales tax rate is 6%, some areas chose too add additional local taxes.

Sales Tax Collection Discounts In Idaho

While many states allow merchants to keep a small percentage of the sales tax they collect as a collection discount, or compensation for the work put in collecting the tax on behalf of the state, Idaho does not currently allow this.
