Sales tax in Idaho County, Idaho
There is no single sales tax rate in Idaho County. It runs from 6% to 7% depending on the exact address, because Idaho counties cannot levy a sales tax and the cities inside Idaho County set their own. The 6% state rate applies everywhere in the county; everything above that depends on where you are standing.
What is the sales tax rate in Idaho County?
| Idaho state rate | 6% |
|---|---|
| Lowest combined rate in the county | 6% |
| Highest combined rate in the county | 7% |
The two combined figures are the lowest and highest totals found anywhere inside the county. They are not a state rate plus a county rate added together, and adding the rows above will not reproduce them, because cities and special districts levy in between.
Why the rate here is not the whole story
Idaho's state sales tax is 6 percent and Idaho counties have no authority to levy a general sales tax at all, so this county's own rate is a confirmed zero. Idaho Code section 50-1044 gives the power to resort cities only, meaning a city of 10,000 or fewer people that derives the major portion of its economic well being from businesses catering to visitors, and section 50-1046 requires 60 percent voter approval before a city may adopt one. Section 50-1048 speaks of what would follow "in the event that counties are given local-option nonproperty tax authority", which is the legislature saying plainly that they have not been. 1 city in Idaho County levies a local option tax. Riggins charges 2 percent on lodging occupancy and on liquor by the drink and prepared meals under Ordinance 174, and its own municipal tax return carries a fourth line charging 1 percent of total retail sales, so general merchandise appears to run to 7 percent inside Riggins against 6 percent everywhere else in the county. The 7 percent ceiling is marked as strong rather than primary because the city's website serves a bot challenge that was not bypassed and the current ordinance PDF could not be retrieved, so the 1 percent retail rate comes from an archived copy of the city's own tax return form rather than from a live city document. Riggins is a town of about 400 people, so this ceiling covers a very small part of a large county. Idaho does not exempt groceries. Food is taxed at the full 6 percent and residents instead claim a food tax credit on their Idaho income tax return, worth $155 per person for 2025 or up to $250 if receipts for sales tax paid on food are submitted, so a grocery receipt in Idaho carries tax that a shopper gets back once a year rather than at the register.
How do I find the exact rate for an address in Idaho County?
Because the rate changes within the county, an address is the only way to get it right. Use Idaho's own lookup. A vendor's calculator is not the state speaking.
Who has to collect sales tax in Idaho County?
A seller with a physical presence in Idaho collects at the rate for the address where the sale takes place. A remote seller collects once it passes Idaho's economic nexus threshold, which is a separate question from the rate and is covered on our sales tax nexus checker. Marketplace facilitators generally collect on behalf of their sellers.
