What shoppers pay in Post Falls, ID

Post Falls is a smaller Idaho community, the 10th most populous city in the state, with roughly 38,485 residents. Idaho charges a 6.00% state sales tax, and counties, cities and special districts add their own levies on top. Across the state those local add-ons average 0.03%, bringing the typical combined rate to 6.03%.

Census figures (ACS 5-Year 2023) put median household income in Post Falls at $73,313, or about $1,410 a week. At the state's typical combined rate, a $500 purchase adds $30.15 in tax, and a $2,000 one adds $120.60. That larger figure works out to roughly 9% of a week's median household income here, which is why timing a big appliance or furniture purchase around a sales tax holiday can be worth the wait.

One caveat matters before you budget from these numbers. The 6.03% above is a statewide average, not a rate we can confirm for a specific Post Falls address. Because special districts draw their own boundaries, two addresses a few streets apart can fall under different combined rates. For a purchase where the difference matters, check the rate lookup published by the Idaho revenue department for the exact delivery address. Groceries are taxable in Idaho, so the rate applies to a weekly food shop as well.
