Kentucky Sales Tax Calculator (2026) — Add or Reverse Tax
Kentucky's combined sales tax rate is 6.00% (6.00% state). Use the calculator below to add Kentucky sales tax to a price, or reverse a tax-included total to find the pre-tax price and exact tax amount.
How to use this calculator:
- Adding tax — enter a pre-tax price, pick "Add tax to price," and the calculator applies the Kentucky rate to show the tax amount and final total.
- Reversing (extracting) tax — enter a total that already includes tax, pick "Extract tax from total," and the calculator divides by 1 + the rate to isolate the pre-tax price and the exact tax paid.
- Pick the rate that matches your situation: the average combined rate is a good statewide estimate, but the state-only or maximum-local rate is more precise if you know the exact city or county.
Understanding Kentucky Sales Tax
Kentucky's state sales tax rate is 6.00%, with no additional local sales tax in most of the state.
Kentucky is removing its 200-transaction economic nexus test effective August 1, 2026, joining the 16+ states that tax based on revenue alone.
Kentucky also levies a state income tax, which shapes how much the state relies on sales tax revenue relative to other funding sources.

Why Reverse Sales Tax Calculation Matters
Receipts, invoices, and marketplace payouts usually show only the tax-included total — not the pre-tax price. Reversing the calculation matters for bookkeeping (separating revenue from tax collected), expense reports (reimbursing only the pre-tax cost), and price comparisons (checking what an item actually costs before Kentucky's tax is applied). Because dividing by (1 + rate) is not the same as simply subtracting the rate from the total, doing this by hand is a common source of errors — the calculator above handles it exactly.

History & Rate Breakdown
Kentucky adopted its sales and use tax in 1960 at a 3% rate, raising it to 5% in 1968 and to its current 6% in 1990. Since 2018, Kentucky has significantly broadened its tax base to cover more than 30 additional service categories that were previously untaxed.
Kentucky's 6% rate is entirely state-level with no local add-ons anywhere — every city and county in Kentucky charges the identical 6%, one of a small handful of states with true statewide rate uniformity.
Where the Money Goes
With no local sales tax revenue-sharing to manage, all of Kentucky's sales tax revenue flows directly to the state general fund, which increasingly includes revenue from the services (from landscaping to photography) added to the tax base since 2018.
Business Use Case: Registering & Collecting Kentucky Sales Tax
A service business newly subject to Kentucky sales tax since the 2018-2023 base expansion — for example a photography studio or a laundry service — must register and charge the flat 6% rate just like a traditional retailer, with no local-rate lookup required since Kentucky has no city or county add-ons.
Sales Tax Terms Glossary
Combined rate
The state sales tax rate plus any applicable local (city, county, or special district) rates — the actual rate charged at checkout in a given location.
Reverse sales tax
The process of working backward from a tax-included total to find the pre-tax price and the exact tax amount, using total ÷ (1 + rate) = pre-tax price.
Economic nexus
A sales threshold (in dollars, transaction count, or both) that obligates an out-of-state seller to collect and remit sales tax even without a physical presence in the state.
Marketplace facilitator
A platform (e.g. Amazon, Etsy, eBay) that collects and remits sales tax on behalf of third-party sellers under most states’ marketplace facilitator laws.
Real-World Example
A $500.00 purchase in Kentucky at the average combined rate of 6.00%:
- Tax amount: $500.00 × 6.00% = $30.00
- Total price: $500.00 + $30.00 = $530.00
Kentucky Sales Tax Compliance for Sellers
Remote and online sellers establish economic nexus in Kentucky once they exceed $100,000.00 in annual sales (no separate transaction-count test). Once nexus is established, a seller must register with the state, collect Kentucky sales tax at checkout, and file returns on the state's required schedule. Marketplace facilitators (Amazon, Etsy, eBay, Walmart) generally collect and remit on behalf of third-party sellers automatically.
