The Kentucky Limited Liability Entity Tax, or LLET, is an annual tax that corporations and limited liability pass-through entities doing business in Kentucky must pay on top of (and partly as a credit against) Kentucky income tax. Every subject entity owes at least $175 a year, even with no revenue. Above $3 million in total gross receipts or gross profits, the tax is calculated two ways and you pay whichever is lower.1Justia Law. Kentucky Code 141.0401 – Limited Liability Entity Tax – Exemptions – Rate
Who Has to Pay
Two broad groups owe the LLET under KRS 141.0401: corporations (both C-corps and S-corps) and limited liability pass-through entities, meaning LLCs, limited partnerships, limited liability partnerships, and business trusts.1Justia Law. Kentucky Code 141.0401 – Limited Liability Entity Tax – Exemptions – Rate The common thread is liability protection. If your business structure shields owners from personal responsibility for the entity’s debts, Kentucky treats that shield as a privilege worth taxing. Filing articles of incorporation or organization with the Secretary of State is what triggers the obligation, not revenue. An LLC with zero sales still owes $175.
Several categories sit outside the tax entirely:
- Sole proprietorships, because the owner and the business are legally the same person.
- General partnerships, because each partner carries unlimited personal liability.
- Organizations exempt under Section 501 of the Internal Revenue Code, including 501(c)(3) charities.1Justia Law. Kentucky Code 141.0401 – Limited Liability Entity Tax – Exemptions – Rate
- Financial institutions defined in KRS 136.500, which fall under a separate taxing regime.1Justia Law. Kentucky Code 141.0401 – Limited Liability Entity Tax – Exemptions – Rate
- Public service corporations taxed under KRS 136.120, such as utilities.1Justia Law. Kentucky Code 141.0401 – Limited Liability Entity Tax – Exemptions – Rate
Out-of-State Businesses and Kentucky Nexus
A business based outside Kentucky can still owe the LLET. Kentucky uses the term “doing business” broadly, covering any profit-seeking activity within the state.2Kentucky Department of Revenue. 103 KAR 16:240 Nexus Standard for Corporations and Pass-Through Entities
One point surprises out-of-state sellers: the federal protection in P.L. 86-272, which shields companies whose only in-state activity is soliciting sales of tangible goods, does not block the LLET. That federal law applies to net income taxes, and Kentucky treats the LLET as a separate levy on gross receipts or gross profits. A traveling sales force in Kentucky can be enough to pull you in at the $175 minimum or more.2Kentucky Department of Revenue. 103 KAR 16:240 Nexus Standard for Corporations and Pass-Through Entities
How the Tax Is Calculated
The LLET runs on two numbers, and you calculate it both ways before paying the lower result.
Kentucky gross receipts are total revenue sourced to Kentucky. If you operate in multiple states, Kentucky uses a single sales factor with market-based sourcing under KRS 141.120, meaning receipts are sourced to where your customers receive the goods or services, not where you produce them.1Justia Law. Kentucky Code 141.0401 – Limited Liability Entity Tax – Exemptions – Rate3Kentucky Department of Revenue. Corporation Income and Limited Liability Entity Tax
Kentucky gross profits are Kentucky gross receipts minus returns and allowances on those receipts and the cost of goods sold on those receipts. For service businesses with little cost of goods sold, the two figures stay close.1Justia Law. Kentucky Code 141.0401 – Limited Liability Entity Tax – Exemptions – Rate
You also need total gross receipts and total gross profits from all sources, not just Kentucky. Those nationwide totals determine your rate tier.
Tier 1: $3 Million or Less From All Sources
If your total gross receipts from all sources are $3 million or less, the LLET on the gross receipts side is $175. The same floor applies on the gross profits side when total gross profits from all sources are $3 million or less. Most small businesses land here and owe only the $175 minimum.
Tier 2: Between $3 Million and $6 Million
This range phases in the full rate to avoid a cliff. On the gross receipts side, you start with $0.095 per $100 of Kentucky gross receipts, then subtract a discount of $2,850 multiplied by ($6 million minus your total gross receipts) divided by $3 million. As total gross receipts approach $6 million, the discount shrinks to zero.
On the gross profits side, the same structure applies at $0.75 per $100 of Kentucky gross profits, with a discount of $22,500 multiplied by the same fraction. Compare the two results and pay the lower one. Neither result can drop below $175.
Tier 3: $6 Million or More
At this level, the full rates apply with no discount:
- Gross receipts method: $0.095 per $100 of Kentucky gross receipts.
- Gross profits method: $0.75 per $100 of Kentucky gross profits.
Again, you pay whichever calculation produces the smaller number. A company with $10 million in Kentucky gross receipts would owe $9,500 under the receipts method. If that same company had $2 million in Kentucky gross profits, the profits method would produce $15,000. The company pays $9,500. Running both calculations carefully, rather than defaulting to one, is the single most taxpayer-friendly feature of the statute.
Regardless of tier or credits, every subject entity owes at least $175. That floor applies even after subtracting credits allowed elsewhere in the Kentucky Revised Statutes.1Justia Law. Kentucky Code 141.0401 – Limited Liability Entity Tax – Exemptions – Rate
The Credit Against Kentucky Income Tax
The LLET is not a standalone cost piled on top of income tax. The amount you owe under the LLET, minus the $175 minimum, generates a nonrefundable credit against Kentucky income tax. In practice, the LLET works like a prepayment toward your income tax bill, with a $175 floor that can never be recovered.1Justia Law. Kentucky Code 141.0401 – Limited Liability Entity Tax – Exemptions – Rate
For corporations, the credit equals the current-year LLET (after other credits under KRS 141.0205) reduced by $175, applied against corporate income tax under KRS 141.040. Any leftover credit is disallowed and does not carry forward.
For pass-through entities, the credit flows to members, shareholders, or partners in proportion to ownership. Each owner applies their share, again reduced by the $175 entity-level minimum, against the income tax owed on income from that entity. Unused credit is disallowed.
Because the credit is nonrefundable and does not carry forward, the LLET adds a real cost only when it exceeds your Kentucky income tax liability. For profitable entities with meaningful income tax bills, the LLET is largely offset. For entities with low or no income tax liability, the $175 is the practical floor.
Filing, Deadlines, and Estimated Payments
The LLET is reported on the same return as your Kentucky income tax. C-corporations use Form 720, S-corporations use Form 720S (or Form PTE), and partnerships use Form 765 (or Form PTE). Forms are available on the Department of Revenue website and can be filed electronically or by mail.4Kentucky Department of Revenue. Form 720 – Kentucky Corporation Income Tax and LLET Return
The return and payment are due the 15th day of the fourth month after your fiscal year ends. For calendar-year filers, that’s April 15. If the date lands on a weekend or legal holiday, the deadline moves to the next business day.5Kentucky Department of Revenue. Kentucky Partnership Income and LLET Return Instructions
Kentucky grants automatic extensions tied to the federal process. If you file federal Form 7004, Kentucky honors it for the same tax year as long as you attach a copy to your Kentucky return. Corporations get a seven-month extension; pass-through entities get six. An extension to file is not an extension to pay. Any tax you expect to owe must still be paid by the original deadline, using Form 720EXT to submit the payment. Submitting the federal extension after you’ve already filed, rather than attaching it to the return, is not valid in Kentucky and triggers late-filing penalties.6Kentucky Department of Revenue. File a Corporation Income Tax Extension
Corporations and S-corporations generally follow federal estimated tax rules, with four quarterly installments of 25% each due April 15, June 15, September 15, and December 15.3Kentucky Department of Revenue. Corporation Income and Limited Liability Entity Tax Partnerships owe estimated payments only when expected LLET exceeds $5,000, on a schedule that depends on when during the year you realize you’ll cross that threshold.5Kentucky Department of Revenue. Kentucky Partnership Income and LLET Return Instructions Underpaying or skipping installments carries a 10% penalty on the shortfall, with a $25 minimum.
Penalties for Late Filing and Payment
Kentucky’s penalties escalate the longer you wait, and the late-filing and late-payment penalties can stack.5Kentucky Department of Revenue. Kentucky Partnership Income and LLET Return Instructions
- Late filing: 2% of the LLET due for each 30-day period (or fraction) the return is overdue, capped at 20%. Minimum $10.
- Late payment: 2% of the LLET due for each 30-day period the payment is overdue, capped at 20%. Minimum $10.
- Failure to file after a written request from the Department of Revenue: 5% per 30-day period, capped at 50%. Minimum $100.
- Underpaid estimated tax: 10% of the underpayment. Minimum $25.
Statutory interest also accrues from the original due date. On a $10,000 LLET liability, going five months with no return and no payment produces $1,000 in filing penalties plus $1,000 in payment penalties plus interest. Filing on time with an extension and paying what you owe eliminates the filing penalty entirely.
Final Returns When Closing a Business
Dissolving or withdrawing from Kentucky does not erase the LLET for the final year. You file a short-period return through the dissolution date and check the box marking it as final. Two rules matter. You cannot annualize gross receipts or gross profits on a short-period final return; three months of activity is reported as three months. And the $175 minimum still applies for the short period, even if the business earned almost nothing before closing.7Kentucky Department of Revenue. Kentucky Corporation Income Tax and LLET Return Instructions
The Department of Revenue and the Secretary of State have separate closure requirements. Filing the final tax return does not dissolve the entity, and dissolving with the Secretary of State does not satisfy your tax obligations. Contact both when winding down.
How the Pass-Through Entity Tax Election Interacts
Kentucky’s pass-through entity tax election, filed on Form 740-PTET, lets the entity pay Kentucky income tax at the entity level rather than passing it to owners’ individual returns. Because the tax is paid by the business, it is not subject to the federal individual cap on state and local tax deductions, which starts at $40,000 ($20,000 for married filing separately) in 2025 and rises 1% annually beginning in 2026, with a phaseout reducing the benefit by 30% of the amount modified adjusted gross income exceeds $500,000 ($250,000 for married filing separately) and a guaranteed $10,000 floor.8Internal Revenue Service.

The PTE election is separate from the LLET. The $175 minimum LLET still applies whether or not you elect, and the LLET credit still applies against whatever Kentucky income tax the entity or its owners end up owing.
