Obtain required licenses and permits
Business Licenses in Kentucky
State Tax Registration
Before addressing local or industry-specific licensing, most businesses operating in Kentucky must first register with the Kentucky Department of Revenue. This registration is how a business obtains a Kentucky tax account, which is generally required for collecting and remitting sales and use tax, withholding employee income tax, and paying other applicable state taxes. Registration is typically completed through the Kentucky Business One Stop portal alongside other formation steps, and a Kentucky sales and use tax permit (sometimes called a seller's permit) is free to obtain and does not need to be renewed once issued. This state tax registration is separate from — and generally a prerequisite to — the local occupational licensing and industry-specific licensing discussed below.
Local Occupational Licenses
Kentucky does not issue a general, statewide business license. Instead, the primary licensing requirement for most businesses comes from the city and/or county where the business operates, in the form of what Kentucky calls an "occupational license." Despite the name, this isn't simply a one-time permit — it functions as a local tax, typically assessed as a percentage of the business's net profits, gross receipts, or employee wages, depending on the jurisdiction.
Requirements, rates, and procedures vary significantly by city and county, so there's no single statewide form or fee. Generally, businesses can expect to:
Register with the city and/or county where the business is physically located, or where business activity takes place;
Pay an occupational license fee, often calculated as a percentage of net profits (commonly in the range of 1–2.5%, though this varies by jurisdiction);
File periodic returns (often quarterly for employee wage withholding, and annually for net profits), even in years with no profit, unless the business has tax-exempt status; and
Renew the license periodically, with some jurisdictions assessing this as an annual flat fee in addition to (or instead of) profit-based assessments.
Because requirements are set locally, the right starting point is contacting the city or county clerk's office, or local revenue/finance department, where the business is located — for example, the Louisville Metro Revenue Commission, the Lexington-Fayette Urban County Government Division of Revenue, or the relevant county clerk in smaller jurisdictions. Businesses operating in multiple cities or counties may need to register with each one, though some counties offer a countywide license for businesses with multiple locations.
In addition to the occupational license itself, businesses may need related local approvals depending on the nature and location of the business, such as a zoning permit confirming the business's location is approved for its intended use, a certificate of occupancy confirming the space meets building and safety codes, or a home occupation permit if the business is run from a residential address.
Licenses for Particular Lines of Business
Beyond state tax registration and local occupational licensing, certain industries and professions require additional licenses or permits at the state or federal level before they may legally operate. These requirements exist independently of — and in addition to — the registrations discussed above. Common examples include:
Professional services. Licensed professions such as accountants, attorneys, physicians, nurses, engineers, architects, real estate agents, and cosmetologists must hold the appropriate license from their governing state board, regardless of how the underlying business is structured.
Food service and sales. Restaurants, food trucks, caterers, grocery stores, and temporary food vendors generally need a health permit from the local health department, in addition to any required state food-safety registration.
Alcohol. Businesses that manufacture, distribute, or sell alcoholic beverages need a license from the Kentucky Department of Alcoholic Beverage Control, and may also need federal permits (for example, a Distilled Spirits Plant registration from the federal Alcohol and Tobacco Tax and Trade Bureau) depending on the activity.
Childcare. Childcare facilities and family child care homes typically need licensing or certification through the state, in addition to any local permitting.
Construction and contracting. Contractors may need state or local licensing depending on their trade (such as electrical or plumbing work), along with any required building permits for specific projects.
Environmental permits. Businesses that produce air emissions, discharge wastewater, withdraw significant water from a stream or groundwater source, or generate hazardous waste may need an environmental permit or authorization before beginning those activities.
Because licensing requirements depend heavily on the specific nature of the business, businesses should research requirements applicable to their particular industry, in addition to confirming state tax registration and local occupational licensing obligations. The Kentucky Business One Stop portal maintains a searchable database of state-level licenses and permits by business type, which can serve as a starting point for identifying what may apply.
