Kentucky Sales Tax Calculator

In most of America, “what’s the sales tax here?” depends on which side of a city boundary the cash register sits — thousands of overlapping state, county, and city rates. Kentucky abolished that problem by never allowing it: the Commonwealth levies a flat 6% statewide under KRS Chapter 139, and no city or county may add a local sales tax. Louisville, Lexington, Bowling Green, and the smallest Appalachian town all charge exactly the same rate. That leaves only one real question — is the item taxable at 6% or exempt at 0% — and that is what this calculator answers.

The math (short) and the classification (long)

tax   = price × 0.06     for taxable items
tax   = 0                for exempt items (groceries, prescriptions, …)
total = price + tax

The arithmetic is trivial; the classification is where Kentucky gets interesting:

The full exemption rules live with the Kentucky Department of Revenue’s sales & use tax pages.

Worked examples

• $200 pair of shoes: 200 × 0.06 = $12.00 tax → $212.00 total.
• $200 grocery order: exempt → total stays $200.00.
• Mixed basket — $80 groceries + $40 candy: only the candy is taxable, so tax = 40 × 0.06 = $2.40; total $122.40. This split is why your supermarket receipt shows tax on a fraction of the subtotal.
• $30,000 car: $0 sales tax at the dealer — but a 6% motor vehicle usage tax ($1,800) is collected at the county clerk when the vehicle is titled. Same rate, different statute (KRS 138.460), different tool.

The grocery line is finer than it looks

Kentucky follows the multistate Streamlined Sales Tax definitions, so the grocery exemption turns on precise definitions rather than intuition. “Candy” excludes anything containing flour — which is why a chocolate bar is taxable but many cookies and candy bars with flour count as exempt groceries. Soft drinks (sweetened, no milk or >50% juice) are taxable while bottled water and 100% juice are exempt. Rotisserie chicken sold hot is prepared food at 6%; the same chicken cold from the case is usually exempt groceries. Cashiers do not decide any of this — the point-of-sale system maps each UPC to a category, and this calculator’s item-type switch mirrors that logic.

Services: the quiet expansion

Historically Kentucky taxed goods and spared services, but two waves of legislation (2018 and the 2022 session’s HB 8, effective 2023) extended the 6% tax to dozens of named services — including streaming video and music, SaaS-style software subscriptions, short-term rentals, personal fitness training, photography, and many repair and personal services. If your business sells services in Kentucky, check the DOR’s current taxable-services list rather than assuming exemption; the list has grown in every recent budget cycle as the state trades income-tax cuts for a broader sales-tax base. That linkage is explicit policy: the same statutes that step the income tax down toward 3.5% broaden what the 6% applies to.

Use tax: the same 6% by another name

Buy a taxable item from a seller who does not collect Kentucky tax — a small out-of-state web shop, a marketplace edge case, an overseas retailer — and you owe consumer’s use tax at the identical 6%, reportable on your Kentucky return. Since the South Dakota v. Wayfair decision (2018), remote sellers above Kentucky’s economic-nexus threshold ($100,000 in sales or 200 transactions into the state) must register and collect, so most large online purchases now arrive with the 6% already charged.

Edge cases

Residential utilities are exempt only for your primary residence — since 2023, landlords and owners of second homes must ensure the account has the declaration of domicile on file or the utility adds 6%. Nonprofit and government purchases are exempt with a valid exemption certificate, not automatically. Occasional sales (garage sales, one-off private sales of used goods) are generally outside the tax. Shipping charges are taxable when the goods are taxable and separately-stated delivery is part of the sale. And Kentucky holds no general sales-tax holiday — unlike Tennessee or Ohio, there is no back-to-school weekend when the 6% pauses.
