Kentucky Contractor Taxes and Licensing: Sales Tax, Occupational Taxes and Licenses

Kentucky contractors are normally treated as service providers, not liable for tax on their receipts. They pay the flat 6% sales tax on materials and fixtures as consumers, and Kentucky has no local sales tax. Two catches: extended warranty contracts on real property became taxable in 2023, and cities and counties levy their own occupational license taxes.

What's distinctive about Kentucky for contractors?

Kentucky flips the usual local-tax problem. Sales tax is simple, a flat 6% everywhere with no county or city add-on. The complexity shows up instead in local occupational license taxes on net profits, payroll and gross receipts, which cities and counties run themselves. The state Department of Revenue (DOR) "does not administer local occupational, net profits or gross receipts taxes," so a contractor working in several cities may file in each. Kentucky also requires workers' comp from the very first employee.

This summary reflects official Kentucky sources as of 2026-10-19. It's general information, not tax advice. Local occupational taxes differ by city and county, so confirm with each locality and a Kentucky CPA.

Do Kentucky contractors charge sales tax on labor?

Usually not. DOR describes contractors as "normally treated as service providers not liable for tax on their receipts." Under regulation 103 KAR 26:070, "a contractor-retailer constitutes the sole exception under which a contractor will be issued a sales tax permit." If you sell items at retail, tax applies to the sale "along with any delivery or installation charges associated with the sale."

The 2023 change: extended warranty and service contracts

Effective January 1, 2023, Kentucky expanded "extended warranty services" to "include contracts covering all real property." DOR warns that contractors "need to understand that payments from clients for extended warranty contracts are now taxable receipts subject to the 6% sales and use tax." If you sell maintenance agreements or warranty plans on HVAC systems, plumbing or roofs, talk to your CPA about collecting tax. Materials that become part of a covered warranty repair "may" be bought on a resale certificate.

Landscaping and janitorial services are also taxable services in Kentucky. A landscaper charges tax to customers, and a builder who buys those services for a project pays the tax "as the consumer." Whether other repair or installation labor became taxable in 2023 is a question to check with the department.

How are materials taxed for Kentucky contractors?

"Except when operating as a retailer, contractors are the consumers of materials and fixtures used in performing their construction, improvements, or repairs to real property." Tax applies "at the time of sale to the contractor." When an out-of-state supplier doesn't collect Kentucky tax, you "report and pay the use tax directly to the department" on a consumer's use tax return. See use tax for contractors and sales tax on labor vs. materials.

What is Kentucky's sales tax rate?

Sales and use tax is "imposed at the rate of 6 percent of gross receipts or purchase price," and "there are no local sales and use taxes in Kentucky." The same 6% applies in Pikeville and Paducah, which makes bids across the state easy to compare.

Which Kentucky contractor licenses do you need?

The Department of Housing, Buildings and Construction (HBC) "administers the permitting and licensing for HVAC, plumbing, boilers, electrical, elevators, manufactured housing, and sprinkler systems." HVAC permits "shall only be issued to a licensed master heating, ventilation, and air conditioning contractor," with a narrow exception for homeowners working on their own homes. We found no state general contractor or roofing license on HBC's pages; check with HBC and your city.

Local licensing: Kentucky's One Stop portal notes local building rules "can vary substantially in different locations." Many cities and counties require an occupational license before you work there. See our contractor license guide.

What income and business taxes apply in Kentucky?

Kentucky's 2026 withholding form says "all Kentucky wage earners are taxed at a flat 3.5% rate with a standard deduction allowance of $3,360," and the same flat rate applies to business income reported by individuals. Corporations pay a "flat 5%" income tax. Corporations and LLCs also owe the Limited Liability Entity Tax (LLET): the lesser of 0.095% of Kentucky gross receipts or 0.75% of Kentucky gross profits, and smaller businesses pay a $175 minimum.

Plan for federal tax, Kentucky's 3.5% and local occupational taxes when you set money aside for quarterly estimated taxes. The quarterly estimated tax calculator handles the federal side; check Kentucky's estimate rules with DOR.

When do Kentucky contractors need workers' comp?

From the first hire. The Department of Workers' Claims says "employers with one or more employees are required to obtain and maintain a policy," and "family members, temporary workers, and part-time workers are considered employees." Individual business owners, true partners and LLC members don't have to cover themselves, but a corporate officer is an employee of the corporation and must be covered. See workers' compensation for contractors.

Local taxes in Kentucky
