How to Start a Business in Kentucky: A Step-by-Step Guide

Starting a business in Kentucky takes four registrations for most founders: your entity with the Kentucky Secretary of State, a free EIN from the IRS, a Kentucky tax account with the Department of Revenue, and a local occupational license tax account with your city or county. There is no single "Kentucky business license." That is the part most people get wrong when they search for one.

Below is each step in order, with the actual fees and agencies, S corp and C corp setup, what Louisville adds, and the deadlines your bookkeeping needs to track.

Step 1: Choose Your Business Structure

Your structure determines your tax treatment, personal liability, and how you can raise money.

Sole Proprietorship

No state formation filing; profit goes on Schedule C of your personal return. The trade-off is unlimited personal liability, which makes it fine for testing a side project and risky for anything with leases or employees.

Limited Liability Company (LLC)

The default for most Kentucky small businesses. An LLC shields personal assets from business debts, and you choose how the IRS taxes it.

• Filing fee: $40 (Articles of Organization)
• Ongoing: $15 annual report, plus Kentucky's limited liability entity tax (LLET), which is a $175 minimum for most small LLCs
• Downside: All profit is subject to self-employment tax unless you elect S corp taxation

S Corporation

A tax election, not an entity type. You form an LLC or corporation, then elect S status with the IRS. Working owners take a reasonable salary through payroll, and remaining profit passes through without self-employment tax. The cost is payroll compliance and a limit of 100 shareholders with one class of stock.

C Corporation

The structure venture investors expect. It supports multiple stock classes, option pools, and unlimited shareholders. Profits are taxed at the corporate level (21% federal, 5% Kentucky) and again when paid out as dividends.

For most Louisville founders: If you plan to raise venture capital, form a Delaware C corp and register it in Kentucky as a foreign corporation. If you are bootstrapping or building a services or local business, a Kentucky LLC is usually the right call.

Do You Need a Business License in Kentucky?

No, not a general one. Kentucky's Business One Stop Portal states plainly that Kentucky does not have a statewide business license that applies to all businesses. What you need instead is:

1. Entity registration with the Kentucky Secretary of State (LLCs, corporations, LPs). Sole proprietors skip this but file an assumed name with their county clerk if they use a name other than their own.
2. State tax registration with the Kentucky Department of Revenue, if you will collect sales tax, have employees, or owe corporate income tax or LLET.
3. Local occupational license tax registration with your city or county. This is what people usually mean by a "business license" in Kentucky. In Louisville, it is the Louisville Metro Revenue Commission.
4. Industry-specific licenses, only if your business needs one: food service permits, alcohol licenses, contractor licenses, or a professional license from a state board (law, medicine, accounting, cosmetology, real estate, and so on).

The Kentucky Business One Stop Portal is the state's starting point. It walks you through these registrations and links out to each agency.

Step 2: Register with the Kentucky Secretary of State

LLCs: Articles of Organization

File online through the Secretary of State's FastTrack system or on the paper form. The fee is $40. You need your LLC name, a registered agent with a Kentucky street address, your principal office address, and the organizer's name. The Secretary of State waives the fee for qualifying veteran-owned businesses.

Name availability and registered agent

Search the Secretary of State business database before you file. Your name must be distinguishable from every entity already on record. Every LLC and corporation must keep a registered agent with a physical Kentucky address. You can be your own agent if you live in Kentucky, or use a commercial agent service.

Annual report

Every LLC and corporation files a $15 annual report with the Secretary of State between January 1 and June 30, starting the year after you form. Miss it and the state administratively dissolves the entity. Put it on your calendar now.

How to Create a C Corp in Kentucky

1. Pick the state. For a VC-backed company, incorporate in Delaware, then file for a Certificate of Authority with the Kentucky Secretary of State ($90) so you can do business here. For a corporation that will stay local, incorporate directly in Kentucky.
2. File Articles of Incorporation with the Kentucky Secretary of State. The cost is a $40 filing fee plus an organization tax based on authorized shares: 1 cent per share up to 20,000 shares, with a $10 minimum. Authorizing 1,000 shares costs $50 total; 20,000 shares costs $240.
3. Adopt bylaws, appoint directors, and issue stock. Founders should sign stock purchase agreements and, if shares vest, file IRS 83(b) elections within 30 days.
4. Get an EIN and register with the Department of Revenue for corporate income tax and LLET.

How to Create an S Corp in Kentucky

1. Form the entity. Either an LLC ($40) or a corporation ($50 minimum) as described above.
2. Get an EIN from the IRS.
3. File IRS Form 2553. The deadline is no more than 2 months and 15 days after the beginning of the tax year the election should take effect, or any time during the prior tax year. For a calendar-year business formed January 1, that means by March 15. An LLC that files Form 2553 is treated as a corporation automatically and does not need to file Form 8832 as well. If you miss the deadline, the IRS offers late-election relief under Rev. Proc. 2013-30.
4. Nothing extra for Kentucky. Kentucky has no separate state S election. A corporation that is an S corp for federal purposes files as one in Kentucky (on Form PTE) and pays LLET, minimum $175.
5. Run payroll. Owner-employees must be paid a reasonable salary, which means registering for Kentucky withholding, unemployment insurance, and, in Louisville, occupational tax withholding.

Step 3: Get an EIN from the IRS

An Employer Identification Number is your federal tax ID. You need it to open a bank account, run payroll, and register for state taxes. Apply online at irs.gov. It is free and issued immediately at the end of the online application. Never pay a third party for an EIN.

Step 4: Register for Kentucky State Taxes

The Kentucky Department of Revenue uses one form, the Kentucky Tax Registration Application (Form 10A100), filed online through MyTaxes.ky.gov. One application covers sales and use tax, employer withholding, corporation income tax, and LLET, among others. There is no fee for a sales tax permit.

What you may owe:

• Income tax: Kentucky's individual rate is a flat 3.5% for 2026 (it was 4% for 2024 and 2025). LLC and S corp profits flow through to owners at that rate. C corps pay a flat 5% corporate income tax.
• Limited Liability Entity Tax (LLET): Corporations and LLCs (including S corps and single-member LLCs) pay LLET. If gross receipts or gross profits are $3 million or less, it is the $175 minimum. Sole proprietors and general partnerships are exempt.
• Sales and use tax: 6% statewide, with no local sales taxes on top.
• Employer withholding: Required once you have employees, including yourself if you run an S corp payroll.
• Unemployment insurance: Registered separately with the Kentucky Office of Unemployment Insurance, not on Form 10A100. New employers pay 2.7% on the first $12,000 of each employee's wages in 2026.

Step 5: Register Locally (Louisville Metro Occupational License Tax)

Kentucky cities and counties tax business activity through occupational license taxes, and every business in Louisville/Jefferson County must register with the Louisville Metro Revenue Commission before it starts doing business. The Revenue Commission says there is no separate local business license for most businesses. The tax registration is the requirement.

• One tax, two ways it is collected. The Louisville Metro occupational license tax is 2.2% (1.25% Metro, 0.75% school boards, 0.20% TARC). Businesses pay it on net profits earned in Louisville Metro on Form OL-3. Employers withhold it from employee wages: 2.2% for Jefferson County residents and 1.45% for nonresidents, who do not pay the school board portion.
• How to register: Online through the Revenue Commission's eMINTS portal, or with the paper Registration Application for Tax Account Number.
• Deadlines: The annual OL-3 is due the 15th day of the 4th month after your fiscal year ends (April 15 for calendar-year businesses). Employer withholding returns are due quarterly.
• Suburban cities: Some cities inside Jefferson County, such as Jeffersontown, St. Matthews, and Shively, levy their own occupational taxes or fees on top of Metro's.

Step 6: Open a Business Bank Account

Keep business and personal money separate from day one; commingling funds is one of the fastest ways to lose your liability protection. Banks typically ask for your EIN letter, filed Articles, operating agreement or bylaws, and a photo ID. Louisville-based options include Republic Bank and Stock Yards Bank & Trust.

Step 7: Get Business Insurance

• Workers' compensation: Required by Kentucky law once you have one or more employees (agricultural work is the main exception). Failing to carry it is a civil penalty of $100 to $1,000 per offense, with each employee and each day counted as a separate offense, and officers who knowingly allow it can be held personally liable. Coverage is available from private insurers or Kentucky Employers' Mutual Insurance (KEMI).
• General liability, professional liability (E&O), and property coverage: Landlords usually require general liability; E&O matters for consultants and software companies.

Step 8: Set Up Bookkeeping and a Tax Calendar

Most new Kentucky businesses get into trouble on deadlines, not on rates. Set up accounting software (or hire a bookkeeper) in the first month and track these dates:

Reconcile bank accounts monthly, run payroll through a provider that handles Kentucky and Louisville withholding, and use a Kentucky CPA in year one, particularly if you elect S corp status.

What Tax Advantages Does Kentucky Offer Businesses?

Inventory Tax Credit and Low Rates on Manufacturing Property

Kentucky does tax business inventory as property, but the state rate is only 5 cents per $100 of value, and a nonrefundable inventory tax credit lets businesses claim 100% of timely paid inventory property tax against Kentucky income tax or LLET (it cannot reduce LLET below the $175 minimum). Manufacturing machinery is taxed at 15 cents per $100 and raw materials at 5 cents per $100, both state-only, with no local property tax.

Kentucky Angel Investment Tax Credit

Investors who put at least $10,000 into a qualified Kentucky small business can receive a state tax credit of 25% of the investment, or 40% if the business is in one of the state's Heritage Counties (Jefferson County is not one). Credits are capped at $200,000 per investor per year, with a $3 million statewide annual cap. Details are in our Kentucky grants and funding guide.

Job and Investment Credits

• Kentucky Small Business Tax Credit (KSBTC): Businesses with 50 or fewer full-time employees that create a job and invest at least $5,000 in qualifying equipment can earn up to $3,500 per new job, capped at $25,000 a year.
• Kentucky Business Investment (KBI): Income tax credits and wage assessments for up to 10 years for companies in eligible industries (manufacturing, headquarters, non-retail service or technology) that invest at least $100,000 and create at least 10 full-time jobs.
• Kentucky Reinvestment Act (KRA): Credits worth up to 50% of eligible costs for existing facilities that reinvest at least $2.5 million ($1 million if leased).

No Estate Tax

Kentucky has no estate tax. It does have an inheritance tax, but close relatives such as spouses, children, and siblings are exempt.

What Are the Most Common Mistakes When Starting a Kentucky Business?

Skipping the operating agreement. Kentucky does not require one, but without it the state's default LLC rules govern ownership, profit splits, and what happens when a member leaves.

Forgetting the local occupational tax. Founders register with the state and assume they are done. In Louisville, the 2.2% occupational license tax on net profits applies even to a one-person LLC, and the OL-3 must be filed even in a year with a loss.

Electing S corp status too late, or too early. Miss the 2 months and 15 days window and you wait a year or file for relief. Elect before the business is profitable enough to justify payroll costs and you pay for compliance with no tax benefit.

Overpaying for formation services. The state charges $40 for an LLC and the EIN is free.

Frequently Asked Questions

Do I need a business license in Kentucky?

Kentucky does not have a general statewide business license. Instead, LLCs and corporations register with the Kentucky Secretary of State, businesses that collect sales tax, have employees, or owe corporate tax register with the Kentucky Department of Revenue, and nearly every business registers for occupational license tax with its city or county. Some industries, such as food service, alcohol, contracting, and licensed professions, also need a specific permit or license.

How do I get a business license in Louisville, KY?

Louisville does not issue a general business license for most businesses. Instead, every business operating in Louisville/Jefferson County registers with the Louisville Metro Revenue Commission for an occupational license tax account, online through eMINTS or with a paper registration application. The business then pays 2.2% occupational license tax on net profits and withholds it from employee wages. Restaurants, bars, and some other regulated businesses need additional permits from Louisville Metro agencies.

How much does it cost to form an LLC in Kentucky?

Filing Articles of Organization with the Kentucky Secretary of State costs $40. After that, the LLC files a $15 annual report between January 1 and June 30 each year and pays the limited liability entity tax, which is a $175 minimum for LLCs with $3 million or less in gross receipts or gross profits.

How do I create an S corp in Kentucky?

Form an LLC or corporation with the Kentucky Secretary of State, get an EIN, then file IRS Form 2553 no more than 2 months and 15 days after the start of the tax year the election should take effect. Kentucky automatically follows the federal S election, so there is no separate state form, but the S corp still pays Kentucky's limited liability entity tax, with a $175 minimum.

How do I create a C corp in Kentucky?

File Articles of Incorporation with the Kentucky Secretary of State for a $40 filing fee plus an organization tax based on authorized shares, with a $10 minimum, so 1,000 authorized shares costs $50. Then adopt bylaws, issue founder stock, get an EIN, and register with the Kentucky Department of Revenue. A Delaware corporation doing business in Kentucky instead files a $90 Certificate of Authority.

What business taxes does a Kentucky business pay?

Most Kentucky businesses deal with state income tax (3.5% individual rate for 2026 on pass-through profits, or 5% corporate income tax for C corps), the limited liability entity tax for LLCs and corporations ($175 minimum), 6% sales tax if they sell taxable goods or services, payroll withholding and unemployment insurance if they have employees, and a local occupational license tax, which is 2.2% in Louisville.

Is workers' compensation insurance required in Kentucky?

Yes. Kentucky requires workers' compensation coverage for businesses with one or more employees, with limited exceptions such as agricultural work. The civil penalty for failing to carry it is $100 to $1,000 per offense, and each employee and each day without coverage counts as a separate offense.
