How much is sales tax in Kentucky?
Kentucky enforces a uniform 6% sales tax statewide with no local variations whatsoever. Every address in the state pays the same rate, whether the customer is in Louisville, Lexington, or a remote rural county. Even though there are 1000 taxing jurisdictions on the books, they all apply the identical 6% rate.
Because Kentucky uses a statewide flat rate, address-level lookups don't change the outcome—it's always 6%. This uniformity is rare and makes tax compliance simpler for any business selling into Kentucky. You won't run into surprise jumps or city-specific calculations.
What's taxed and what's exempt in Kentucky
Groceries are exempt from Kentucky's sales tax, so food shopping stays untaxed. Clothing is fully taxable at 6%.
SaaS and digital software are taxable in Kentucky, meaning subscriptions and software licenses incur sales tax. Prescription medicines are exempt. Restaurant meals and prepared foods are taxable.
Do you have to collect Kentucky sales tax? (Economic nexus)
Like most states after the 2018 Wayfair decision, Kentucky requires out-of-state sellers to register and collect once their sales into the state cross an economic-nexus threshold. That line is commonly around $100,000 of sales into Kentucky per year, and some states also count a number of separate transactions — but the exact figure, and whether the transaction count still applies, change from time to time. Confirm Kentucky's current threshold before you rely on it.
If you sell into Kentucky from out of state, the practical question is whether you've crossed that line. Watching your sales into each state is how you know when you're on the hook — and it's the kind of thing that's easy to miss until a notice shows up.

How to calculate Kentucky sales tax
The math itself is simple: multiply the taxable price by the combined rate for the buyer's location. A $100 order at 6% means about $6.00 in tax. The hard part is getting the right rate for every address, keeping it current as rates change, and doing it fast enough to run inside a checkout.
That's what Sefro does. One API call returns the combined state, county, city, and special-district rate for any US address, sourced from state Departments of Revenue and refreshed weekly.
