Kentucky sales tax rates 2026: Calculator, nexus, and due dates

Kentucky sales tax rates by city and county

Kentucky is one of the simplest states for sales tax rate calculation. The 6% state rate applies statewide, and no city, county, or special district adds a local sales tax on top. Every address in Kentucky has the same 6% combined rate.

Because Kentucky is a destination-based state, you apply the rate based on where the customer receives the product. However, since there is only one rate statewide, the destination address does not change the rate — it only determines that Kentucky sales tax applies. All returns are filed with the Kentucky Department of Revenue.

Kentucky nexus thresholds

Remote sellers and businesses with a physical presence in Kentucky are subject to nexus laws. You are required to register and collect sales tax if you trigger “nexus” through a physical presence in the state or by exceeding the economic thresholds as a remote seller.

Kentucky economic nexus

You will trigger Kentucky economic nexus if you exceed either of the following thresholds in the current or previous calendar year:

• Sales threshold: $100,000 in gross receipts from sales into Kentucky (including taxable and nontaxable transactions).
• Transaction threshold: 200 or more separate transactions.

Kentucky uses an “or” standard — exceeding either threshold triggers nexus. Marketplace facilitators must include both their own sales and sales facilitated on behalf of third-party sellers when determining whether they exceed the threshold. Once nexus is triggered, the seller must register and begin collecting Kentucky sales tax.

Kentucky physical nexus

You have physical nexus (and must register from dollar one) if you have:

• Inventory: Storing goods in a warehouse, 3PL, or Amazon FBA fulfillment center in Kentucky.
• Personnel: Employees, contractors, sales reps, or agents conducting business in Kentucky.
• Property: Maintaining an office, storefront, distribution center, or other place of business in Kentucky.

Kentucky sales tax permit registration

Once you trigger nexus, you must register with the Kentucky Department of Revenue before you can legally collect sales tax.

Operating without a permit after crossing the threshold exposes you to back taxes, penalties, and interest from the date nexus was established — not the date you registered.

1. Gather your information. You’ll need your FEIN, estimated sales, business structure details, NAICS code, and bank account information.
2. Submit your application. Register online through the Kentucky Business One Stop Portal or through the Streamlined Sales Tax Registration System (because Kentucky is an SST member state). There is no fee for obtaining a sales tax permit.
3. Note your effective date. Kentucky expects registration promptly upon crossing either the $100,000 sales or 200-transaction threshold. If there’s a gap between crossing the threshold and registering, you may owe back taxes for that period.

If you have questions about your Kentucky registration or compliance history, TaxCloud’s U.S.-based support team typically responds within 2 hours and can review your setup directly.

Kentucky sales tax calculation rules

Kentucky’s calculation rules are among the simplest in the U.S. — a flat 6% rate statewide, no local taxes, and destination-based sourcing. The main compliance nuances involve the expanded taxability of services and digital products under HB 8, which took effect January 1, 2023.

What is taxable in Kentucky?

Taxability in Kentucky is determined by how a product is classified under state law. Below is a high-level summary of how major categories are generally treated for 2026:

• Tangible personal property: Most physical goods — such as furniture, electronics, and standard retail items — are subject to the 6% state sales tax unless a specific exemption applies. Shipping charges are taxable when the seller delivers the product directly; shipping via common carrier or USPS is exempt if separately stated. Handling charges are always taxable.
• SaaS, software, and digital products: Kentucky taxes SaaS (“prewritten computer software access services”) as of January 1, 2023 under House Bill 8. Prewritten software — whether delivered electronically or on a physical medium — is taxable. Custom software is exempt. Digital products — including ebooks, streaming media, mobile apps, and digital audio/audiovisual works — are taxable. The Kentucky Department of Revenue confirmed in January 2026 that AI-powered software is taxable as prewritten computer software.
• Food & groceries: Kentucky exempts most unprepared food and food ingredients from sales tax. Prepared food, candy, soft drinks, and dietary supplements are taxable at the standard 6% rate.
• Clothing: Clothing and footwear are taxable at the standard 6% rate.

What is tax exempt in Kentucky?

Below is a high-level summary of items that are generally tax-exempt in Kentucky:

• Essential exemptions: Kentucky provides specific exemptions for items such as prescription drugs, certain medical devices (prosthetics, hearing aids), and unprepared food and food ingredients.
• Additional exemptions: Sales for resale (with a valid exemption certificate), manufacturing machinery used directly in production, certain agricultural supplies, textbooks required for courses at educational institutions, and purchases by qualifying government agencies and nonprofit organizations.

Kentucky sales tax return due dates and filing frequency

In Kentucky, sales tax returns are due on the 20th of the month following the reporting period. The Kentucky Department of Revenue assigns filing frequency based on your monthly sales tax liability.

Businesses with average monthly sales and use tax liability of $10,000 or more are required to file on an accelerated basis. Accelerated filers report by the 25th of each month, covering the period from the 16th of the previous month through the 15th of the current month.

Critical 2026 compliance notes:

• SaaS is taxable. Since January 1, 2023, Kentucky taxes SaaS and prewritten computer software access services. SaaS sellers who triggered nexus but have not registered face back-tax exposure from that date.
• AI-powered software is taxable. The Kentucky Department of Revenue confirmed in January 2026 that software incorporating artificial intelligence is taxable as prewritten computer software, whether or not the AI component modifies its output based on user data.
• Shipping rules are nuanced. Shipping is taxable when the seller delivers the product directly but exempt when shipped via common carrier or USPS. Handling charges are always taxable. Combined shipping-and-handling charges are fully taxable.
• Zero-return requirement: If you are registered but had $0 in sales this period, you must still file. Failure to file can result in penalties.
• Weekend/holiday rule: If the 20th falls on a weekend or state holiday, your return is due the next business day.

The latest Kentucky sales tax changes

We track Kentucky’s shifting sales tax landscape so you don’t have to.

Here are the most relevant updates for 2026:

• Kentucky eliminates the 200-transaction nexus threshold (August 2026): Kentucky HB 757 removes the state’s 200-transaction economic nexus threshold effective August 1, 2026. Remote sellers will now establish sales tax nexus only when exceeding $100,000 in gross sales to Kentucky purchasers. Businesses registered solely because of transaction volume may need to review whether deregistration is possible under Kentucky’s trailing nexus rules.
• Kentucky confirms AI-powered software is taxable (January 2026): The Kentucky Department of Revenue released guidance confirming that software incorporating artificial intelligence — including SaaS products with AI features — is taxable as prewritten computer software. Software that is explicitly custom-programmed for a single customer remains exempt, but AI that adapts its output based on data input does not qualify as custom software.
