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 and marketplace payouts usually show only the tax-included total, so separating revenue from tax collected — for bookkeeping, expense reports, or checking what an item costs before Kentucky's tax is applied — means working backward from that total. Dividing by (1 + rate) isn't the same as subtracting the rate, which is why the calculator above handles it exactly.

How Kentucky Fits Into the US Sales Tax System
The United States has no federal sales tax — unlike VAT/GST countries where a national rate applies everywhere, US sales tax is set entirely at the state level, and each of the 50 states (plus DC) independently decides whether to levy one, what the rate is, and what's exempt. Kentucky is one of the 45 states (plus DC) that levies a general sales tax. States can also authorize cities, counties, and special districts to add their own local rate on top of the state rate — which is why the "combined rate" shown on this page is a blend, not a single fixed number, and why it can differ from the state rate alone by several percentage points depending on the exact delivery address.
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.
Key terms: combined rate — state rate plus applicable local add-ons; reverse sales tax — working backward from a tax-included total via total ÷ (1 + rate); economic nexus — a sales threshold that obligates an out-of-state seller to collect tax without a physical presence; marketplace facilitator — a platform that remits tax on behalf of third-party sellers.
Real-World Example: Adding Tax to a Price
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
Real-World Example: Extracting Tax From a Receipt Total
A receipt shows a $749.99 tax-included total in Kentucky at the average combined rate of 6.00%:
- Pre-tax price: $749.99 ÷ (1 + 6.00%) = $707.54
- Tax amount: $749.99 − $707.54 = $42.45
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.
