The Kentucky sales tax rate is a critical factor for businesses operating in the Commonwealth, affecting everything from pricing strategy to compliance obligations. As of 2024, Kentucky maintains a state sales tax rate of 6%, one of the more moderate rates across the nation, but the full picture is more nuanced when you factor in local taxes, exemptions, and special circumstances.

State Rate Basics
Kentucky’s base sales tax rate has held steady at 6% for several years, making it relatively business-friendly compared to states like Tennessee (9.55%) or Louisiana (8.45%). This rate applies to the sale of tangible personal property and certain services across the state. However, calling it “just 6%” oversimplifies things—most Kentucky residents and businesses actually pay more than this base rate because of local add-ons.
The 6% state rate is administered by the Department of Revenue, which oversees collection and compliance. This isn’t a new tax; Kentucky has maintained a sales tax since 1960, giving the state plenty of time to refine its rules and procedures. Understanding this baseline is your first step toward proper tax planning and compliance.
Local Taxes by County
Here’s where things get complicated—and where many business owners stumble. Kentucky allows counties and cities to impose their own local sales taxes on top of the state rate. These local taxes typically range from 0.5% to 2%, depending on the jurisdiction. For example, Jefferson County (home to Louisville) has a local rate of 1.5%, while some rural counties may have lower rates.
This means that the effective sales tax rate varies significantly depending on where your business operates or where your customer is located. A sale in Louisville might be taxed at 7.5% (6% state + 1.5% local), while a sale in a different county could be 6.5% or even higher. If you’re running an online business shipping to customers across Kentucky, you need to know these county-by-county variations to collect the right amount.
Many businesses use sales tax software that automatically calculates the correct local rate based on the customer’s address. This is worth the investment—getting it wrong can lead to underpayment penalties and interest charges from the Department of Revenue.
Combined Rates Across Kentucky
Let’s look at some real-world examples of combined rates in major Kentucky cities:
- Louisville (Jefferson County): 7.5% (6% state + 1.5% local)
- Lexington (Fayette County): 6% (6% state + 0% local)
- Bowling Green (Warren County): 6.75% (6% state + 0.75% local)
- Owensboro (Daviess County): 6.5% (6% state + 0.5% local)
- Covington (Kenton County): 7% (6% state + 1% local)
Notice that Lexington has no local sales tax? That’s right—not all Kentucky jurisdictions add a local component. This makes Kentucky’s tax landscape genuinely complicated. If you’re comparing your tax burden to competitors in different Kentucky cities, these differences matter. A 1.5% swing between Louisville and Lexington can meaningfully affect your margins and competitiveness.
Tax Exemptions & Exceptions
Kentucky provides several important exemptions from sales tax that many business owners don’t fully utilize:
- Groceries: Most food items for home consumption are exempt, though prepared foods and restaurant meals are taxable.
- Prescription medications: Exempt, but over-the-counter drugs are taxable.
- Manufacturing equipment: Machinery used directly in production is often exempt or taxed at a reduced rate.
- Resale: If you’re buying inventory to resell, you shouldn’t pay sales tax—use a resale certificate instead.
- Agricultural supplies: Farmers can avoid tax on certain inputs used in production.
The resale certificate is particularly important for retailers and wholesalers. If you’re buying products to resell, you must provide your supplier with a valid resale certificate. Failing to do this means you’ll pay sales tax on inventory, which you’ll then need to reclaim—a hassle that wastes time and creates accounting headaches.
Business Compliance Requirements
Operating a business in Kentucky means you need to register for a sales tax license with the Department of Revenue. This isn’t optional—it’s required before you can legally conduct business. The registration process is straightforward and can be done online through the state’s portal.
Once registered, you’re required to:
- Collect sales tax on taxable sales
- File regular sales tax returns (typically monthly or quarterly, depending on your sales volume)
- Remit collected taxes to the state by the due date
- Maintain detailed records of all sales and exemptions for at least four years
- Keep resale certificates from your customers if you’re a wholesaler or supplier
The filing frequency depends on your sales volume. High-volume businesses file monthly; smaller operations may file quarterly. Missing a filing deadline can result in penalties and interest, so set up calendar reminders or use accounting software that tracks these dates automatically.
Comparison with Neighboring States
How does Kentucky stack up against its neighbors? Understanding regional differences is useful if you’re considering expansion or comparing your tax burden to competitors. Sales tax in Nevada is notably different at 6.85%, while Mississippi sales tax runs 7%. Tennessee doesn’t have an income tax but compensates with a 9.55% sales tax—one of the highest in the nation.
For businesses considering relocation or expansion, Kentucky’s 6% base rate is genuinely competitive. When you factor in the lack of a state income tax in Tennessee but their higher sales tax, Kentucky often comes out ahead for retail operations. However, sales tax in Las Vegas and other western states vary widely, so direct comparison requires looking at your specific business model.
Calculating Sales Tax Correctly
The math is straightforward, but execution matters. To calculate Kentucky sales tax:
Step 1: Determine the taxable sale amount (usually the total price before any discounts applied after tax).
Step 2: Identify the correct tax rate for the customer’s location (state + local).
Step 3: Multiply: Taxable Amount × Tax Rate = Sales Tax Due.
Example: A customer in Louisville buys $100 worth of taxable merchandise. Louisville’s combined rate is 7.5%: $100 × 0.075 = $7.50 in sales tax. Total charge: $107.50.
Sounds simple, right? The challenge emerges when you’re dealing with:
- Mixed purchases (some taxable, some exempt items)
- Trade discounts vs. promotional discounts
- Shipping charges (which may or may not be taxable depending on circumstances)
- Multi-state sales where the customer location determines the rate
This is why many businesses invest in point-of-sale systems or accounting software that handles these calculations automatically. The small cost of software is worth avoiding penalties for underpayment.
Recent Changes in 2024
As of 2024, Kentucky has maintained its base 6% state sales tax rate with no announced changes. However, the state continues to refine its regulations around digital services and remote sales. The key development affecting most businesses is Kentucky’s alignment with national standards on remote seller obligations—if you’re selling to Kentucky customers from out of state, you likely need to collect Kentucky sales tax, even if you have no physical presence in the state.
Additionally, the Department of Revenue has increased its focus on marketplace facilitators like Amazon and eBay, requiring them to collect and remit sales tax on behalf of third-party sellers. If you sell through these platforms, verify that the marketplace is handling tax collection correctly—you’re ultimately responsible if they don’t.
For tax planning strategies more broadly, tax planning strategies that apply across multiple states can help you optimize your overall tax burden when operating in Kentucky and other jurisdictions.
Frequently Asked Questions
What is Kentucky’s current sales tax rate?
Kentucky’s state sales tax rate is 6%. However, when you add local taxes (which vary by county and city), the effective rate ranges from 6% to 7.5% or higher depending on your location. Always check the specific combined rate for your county.
Do I need to charge sales tax on shipping?
In Kentucky, shipping charges are generally taxable if the item being shipped is taxable. However, there are exceptions—for example, if you’re shipping a tax-exempt item, shipping typically isn’t taxed. When in doubt, consult the Department of Revenue or your tax advisor.
What’s the difference between a resale certificate and a sales tax permit?
A sales tax permit (or license) is what you need to legally operate a business and collect sales tax. A resale certificate is a document you provide to suppliers to prove you’re buying inventory for resale, not personal use, so you shouldn’t pay sales tax on those purchases. You need both if you’re a retailer.
Can I claim a credit for sales tax I paid to other states?
Generally, no. Kentucky doesn’t offer credits for sales taxes paid to other states. However, if you overpay Kentucky sales tax, you can claim a credit or refund. Keep detailed records of all tax payments.
What happens if I don’t register for a sales tax license?
Operating without a license is illegal and can result in significant penalties, interest charges, and potential criminal liability. Register with the Department of Revenue before you start selling—it’s free and takes just minutes online.
Are digital services taxed in Kentucky?
Kentucky’s treatment of digital services is evolving. Generally, digital goods and services (like software subscriptions or digital downloads) are not taxed, but this is an area where regulations are changing. Check current guidance from the Department of Revenue or consult a tax professional if you’re selling digital products.
How often do I need to file sales tax returns?
Filing frequency depends on your sales volume. Most businesses file monthly, but high-volume businesses might file more frequently, and very small businesses might qualify for quarterly filing. The Department of Revenue will specify your requirements when you register.
What if I’m selling across state lines from Kentucky?
If you’re shipping to customers in other states, you must collect and remit sales tax in those states if you have “nexus” (a significant connection like inventory, employees, or even economic activity above certain thresholds). This is complex—consider consulting a tax professional if you’re multi-state. For comparison, sales tax in San Diego follows similar multi-state principles.
