Starting a business in Louisville, Kentucky — Kentucky’s largest city, home to UPS Worldport, Humana, Brown-Forman, and a thriving medical and bourbon industry — means navigating a combination of state, county, and municipal requirements. Louisville is in Jefferson County, and entrepreneurs here benefit from Kentucky’s relatively low filing fees, favorable tax treatment of pass-through entities, and a state government that actively recruits small business formation. Clark + Harris guides founders through entity selection, formation, operating agreements, licensing, and the ongoing compliance obligations that begin the day the business is registered.

Choosing the Right Business Entity in Louisville

Limited Liability Company (LLC) — the default choice for most small businesses in Jefferson County. Liability protection, pass-through taxation, minimal formalities. Kentucky’s filing fee is $40 and the annual report fee is $15.
Professional Limited Liability Company (PLLC) — required for licensed professionals in Kentucky (physicians, attorneys, dentists, pharmacists, architects, engineers, others). Each owner must hold the underlying professional license.
S-Corporation election — a federal tax election for an LLC or corporation that changes how the income is taxed. Useful for owner-operators who want to save on self-employment tax.
C-Corporation — the right choice for businesses that plan to raise venture capital. Double taxation is the main trade-off.
Sole proprietorship or general partnership — rarely the right answer. Provides no liability protection.

Kentucky Registration Requirements

Once the entity is chosen, Louisville business owners file the formation documents with the Kentucky Secretary of State. For an LLC, that is the Articles of Organization. For a corporation, the Articles of Incorporation. Both can be filed online for a $40 fee.

Every Kentucky business entity must:

Designate a registered agent — a person or entity with a physical street address in Kentucky (not a P.O. box)
File an Annual Report between January 1 and June 30 each year, with the $15 fee — missing this deadline puts the entity in administrative bad standing
Obtain a federal Employer Identification Number (EIN) from the IRS
Register with the Kentucky Department of Revenue for applicable tax accounts
Obtain a Commonwealth Business Identifier (CBI) through the Kentucky Business One Stop portal

Louisville and Jefferson County Specific Requirements

Beyond state-level registration, Louisville businesses must comply with local requirements:

Jefferson County occupational license tax — most Kentucky counties and cities impose a net-profits tax, gross-receipts tax, or payroll tax. Jefferson County requires registration and periodic filings.
Louisville business license or registration — many Kentucky cities require a city-level business license even for businesses registered with the county
Zoning compliance — whether the location is zoned for the proposed use. For businesses with storefronts, parking, signage, or drive-throughs, Louisville zoning typically must approve before a certificate of occupancy is issued.
Local building permits and inspections — for any construction, remodeling, or change of use
Sign permits — exterior signage almost always requires a permit in Louisville
Food service, alcohol, and other regulated-activity permits — specific to the industry
