6%
Idaho base state sales tax rate

What is the sales tax rate in Idaho?

The Idaho state sales tax rate is 6% at state level, plus any local rate that applies. Sales tax is collected by you at the point of sale and passed on to the state — it is never your money, it just passes through your till on the way to the revenue department.

Sales tax = Price × 0.06
Total = Price + Sales tax

Local sales tax in Idaho

The 6% figure is the state rate. Counties and cities in Idaho may add their own on top, so the rate that actually applies is the combined rate at the address where the sale happens — which for a vendor means the event venue, not your home.

A worked example at the Idaho rate

A $45.00 item at 6% carries $2.70 in state sales tax, so the customer pays $47.70.

Over a show, $1,200.00 in sales at that rate means roughly $72.00 collected on the state's behalf — money that is sitting in your till but is not yours to spend.

Where local rates apply on top, both figures rise. Use the calculator with the combined rate for your venue.

Selling at craft fairs and markets in Idaho

Working backwards from a tax-inclusive total

If you price in round numbers at markets — $50 rather than $45.00 plus tax — the tax is buried in every sale and has to be extracted before you file. Divide the total by 1.06, do not subtract 6% from it; subtracting overstates the tax. The reverse sales tax calculator does this for you.

Frequently asked questions

What is the sales tax rate in Idaho?
The Idaho base state sales tax rate is 6%. Counties and cities may add their own on top, so the combined rate at the point of sale can be higher.
How do I calculate sales tax in Idaho?
Multiply the price by 6% as a decimal, then add it to the price. A $45.00 item carries $2.70 in state sales tax, for a $47.70 total.
Do I need a permit to sell at a craft fair in Idaho?
Usually yes. Most states require a seller's permit or a temporary vendor licence before your first sale, including single-day markets. Check with the Idaho revenue department and the event organiser.
Which rate applies if I live in another state?
The rate where the sale happens. Selling at a Idaho market means the Idaho rate applies to those sales regardless of where you live or where the goods were made.
How do I work out the tax if my prices already include it?
Divide the total by 1.06 to get the pre-tax price, then subtract to find the tax. Do not subtract 6% from the total — that overstates the tax, because the rate applied to the smaller pre-tax figure.
