Kentucky Business Taxes Explained for New Owners

Starting a business in Kentucky means understanding the state's tax landscape. Kentucky has a relatively straightforward tax structure compared to other states, with flat rates on income and no franchise tax on LLCs. But there are still several moving parts: income taxes, entity-level taxes, sales tax, and local licenses. This guide breaks down what you owe and when.

Kentucky's Tax Structure for Businesses

Kentucky imposes three main types of business taxes: income tax on profits, entity-level taxes on certain business structures, and sales tax on goods and services sold. There is no statewide general business license in Kentucky, but your city or county likely requires an occupational license or business tax.

The good news: Kentucky has no franchise tax on LLCs, and income tax rates are flat across the board. The catch: the state's Limited Liability Entity Tax (LLET) applies to both LLCs and corporations, and local occupational licenses can add up depending on your location and profit level.

Individual Income Tax and Business Pass-Through Income

If you operate as a sole proprietor or your business income passes through to you personally as a partner or LLC member, you will pay Kentucky individual income tax on your share of business profits.

Kentucky's personal income tax rate is flat: 3.5% for 2026. There is a standard deduction of $3,360, so income below that threshold is not taxed. This is significantly lower than many surrounding states and applies equally to everyone, regardless of total income.

You will report business income on your Kentucky individual tax return, filed through the Kentucky Department of Revenue. Self-employed income is subject to federal self-employment tax (Social Security and Medicare), but Kentucky has no separate self-employment tax.

LLC Taxes in Kentucky

Operating as an LLC is popular with new owners because it provides liability protection and straightforward taxation. Here is what you need to know about Kentucky LLC taxes:

No Franchise Tax

Kentucky does not impose a franchise tax on LLCs. You will not owe an annual fee just for being in business. This is one of Kentucky's advantages for small business owners.

Limited Liability Entity Tax (LLET)

All LLCs in Kentucky that generate Kentucky-source income or Kentucky gross profits are subject to the Limited Liability Entity Tax, regardless of whether you owe corporate income tax. Here is the rate structure:

• If Kentucky gross receipts or gross profits are $3 million or less: flat $175 minimum tax
• If Kentucky gross receipts or gross profits are between $3 million and $6 million: sliding scale between $175 and the next tier
• If Kentucky gross receipts or gross profits exceed $6 million: the lesser of 0.095% of Kentucky gross receipts or 0.75% of Kentucky gross profits

For most new small businesses, you will owe the flat $175 minimum. Pay this tax when you file your LLC formation paperwork, and again each year if your business continues.

Pass-Through Income Taxation

LLC income does not get taxed at the entity level in Kentucky. Instead, profits pass through to members, who pay personal income tax at the 3.5% flat rate. This is one reason LLCs are tax efficient.

Corporation Taxes in Kentucky

If you choose to incorporate instead of forming an LLC, Kentucky tax rules differ slightly.

Corporate Income Tax

Corporations pay a flat 5% income tax on corporation net income. This is calculated on profits after business expenses and is due with your Kentucky tax return filed each year.

Limited Liability Entity Tax (LLET)

Corporations also owe the Limited Liability Entity Tax using the same $175 minimum structure described above for LLCs. You will owe both the 5% income tax and the LLET.

Double Taxation Consideration

Corporations face potential double taxation: the corporation pays 5% tax on net income, and then shareholders pay personal income tax (3.5%) again when they receive dividends. LLCs avoid this by passing income through directly to members. For most new business owners, an LLC is more tax efficient than a C corporation unless you have specific reasons to incorporate.

Sales Tax in Kentucky

Kentucky imposes a 6% state sales tax on most goods and many services. If you sell taxable products or services, you must collect and remit sales tax.

Who Must Register for Sales Tax

Any business with physical or economic presence in Kentucky that sells taxable goods or services must register for a sales tax permit. You register through the Kentucky Department of Revenue at: https://revenue.ky.gov/Business/Pages/Register-Business.aspx

Registering is free. You receive a permit number that you use to identify yourself as a tax-registered seller.

Sales Tax Exemptions

Some items and services are exempt from Kentucky sales tax, including most grocery food, prescription medications, and certain business-to-business transactions. Review the Kentucky Department of Revenue website to confirm whether your products or services are taxable. If you are unsure, contact the department directly.

Collection and Remittance

You collect sales tax from your customers at the point of sale and remit it to the Kentucky Department of Revenue. The frequency of remittance depends on your sales volume: low-volume sellers may remit quarterly, while higher-volume businesses remit monthly or more often. The Department of Revenue will tell you the schedule after you register.

Local Occupational Licenses and Taxes

While Kentucky has no statewide general business license, many cities and counties impose local occupational licenses or business taxes. These vary widely depending on your location and industry.

Common Local Requirements

Many Kentucky jurisdictions require:

• An occupational license, usually issued by the city or county clerk
• A local occupational tax, calculated on payroll, net profits, or gross receipts
• Industry-specific licenses, such as food service permits, contractor licenses, or professional licenses

Before you open your business, contact your county clerk or city government to ask what licenses and taxes apply to your specific business type. Some jurisdictions charge $50 to $500 or more annually for occupational licenses, and local taxes can be significant depending on how they are calculated.

Where to Apply

The county clerk of the county where your business is located is your first stop. You can also contact the city clerk if your business is within city limits. They will direct you to the right department and explain local requirements.

Registering for Kentucky Taxes

To do business legally in Kentucky, you must register with the Kentucky Department of Revenue for tax purposes.

Tax Account Registration

All businesses register tax accounts through the Department of Revenue using Form 10A100. You can do this online through MyTaxes.ky.gov. Registration is free. Once you register, you receive a Kentucky Tax Account Number, which you use for all interactions with the Department of Revenue, including filing sales tax returns, paying estimated taxes, and reporting LLET liability.

Sales Tax Permit

If you sell taxable goods or services, you must also register for a sales tax permit through the same portal. This is separate from general tax account registration and is required by law if you have sales tax liability.

Timing

Register before you begin business operations. There is no specific deadline, but registering early ensures you can collect sales tax from day one if required and avoid penalties for late registration.

Estimated Tax Payments

If you expect to owe more than $500 in Kentucky tax liability during the year, you are required to make estimated tax payments quarterly. These payments cover both personal income tax on business profits and any entity-level taxes owed.

Quarterly estimated payments are typically due in April, June, September, and December. The exact dates are set by the Kentucky Department of Revenue. Missing estimated tax deadlines can result in penalties and interest, so track these dates on your calendar.

Record-Keeping and Documentation

Good record-keeping is essential for accurate tax filing and reduces your risk if the Department of Revenue audits your business.

Keep records of:

• Income from all sources
• Business expenses, with receipts or documentation
• Sales tax collected and remitted
• Payroll records if you have employees, including wages and taxes withheld
• Quarterly estimated tax payments made
• Any licenses or permits issued

The Kentucky Department of Revenue generally requires you to keep records for at least three years, though some records should be kept longer. Use accounting software or a bookkeeper to automate record-keeping if possible.
