Kentucky LLC Taxes Explained: 3.5% Flat + the LLET (2026)
Kentucky taxes your LLC on more layers than most states — a 3.5% flat income tax, the LLET entity tax, federal self-employment tax, local occupational taxes, and 6% sales tax. Here's every layer, with an estimator that shows your real combined bill.
A default Kentucky LLC is a pass-through: profits flow to your personal return, taxed at Kentucky's flat 3.5% for 2026 (down from 4% in 2025). You'll also pay 15.3% federal self-employment tax on 92.35% of net profit, and your LLC itself owes the LLET — minimum $175/yr. Add local occupational taxes (Louisville ~2.2%, Lexington 2.25%) and 6% sales tax if you sell taxable goods or services. Around $60–80K profit, an S-Corp election (Form 2553) may cut your SE tax.

The 5 Layers of Kentucky LLC Taxation
Federal: income + self-employment tax
Pass-through profits hit your 1040 at your federal bracket, plus 15.3% SE tax on 92.35% of net profit (Social Security + Medicare). This is usually your biggest line.
Kentucky income tax: 3.5% flat
For tax years beginning on or after January 1, 2026, Kentucky's individual rate is a flat 3.5% — down from 4% in 2024–2025, and among the lowest flat rates of any state with an income tax.
The LLET: Kentucky's entity tax
The Limited Liability Entity Tax (KRS 141.0401) hits the LLC itself — $175 minimum for most LLCs, calculated on gross receipts or gross profits above $3M. Detail below.
Local occupational taxes
Cities and counties tax net profits earned in their jurisdiction — Louisville ~2.2%, Lexington 2.25%, most others at their own rates. See Step 7.
Sales tax: 6% flat, if applicable
Collected from customers on taxable goods and many services. One statewide rate, zero local add-ons.

The LLET In Depth (KRS 141.0401)
The Limited Liability Entity Tax is Kentucky's price tag on liability protection — nearly every LLC, S-Corp, and C-Corp owes it, while sole proprietorships and general partnerships don't.
| Kentucky Gross Receipts | Your LLET |
|---|---|
| $3 million or less | $175 flat minimum |
| Above the thresholds | Lesser of 0.095% of gross receipts or 0.75% of gross profits (never below $175) |
- It applies at $0 profit. The $175 minimum is owed even in loss years — it's based on existence, not income.
- Filed with your Kentucky return via the applicable LLET forms (Form 725/PTE family for pass-through LLCs), generally due the 15th day of the fourth month after year-end for single-member LLCs on your schedule, with pass-through entity returns on the entity calendar.
- Pending relief — not yet law: HB 451 (2026 session) proposes exempting entities under $100,000 in Kentucky gross receipts. Repeated versions of this exemption have been introduced since 2024 without passing. Budget the $175 until the Kentucky DOR says otherwise — we'll update this page the day it changes.
The S-Corp Question (~$60–80K Profit)
An S-Corp election doesn't change your LLC legally — it changes how the IRS taxes it. You pay yourself a reasonable salary (subject to payroll taxes) and take remaining profit as distributions that escape the 15.3% SE tax. The election is made on Form 2553 (never Form 8832 — that's for C-Corp elections), and it starts making sense around $60–80K of consistent profit, once the savings outrun the payroll and accounting costs. Kentucky note: S-Corps still owe the LLET, and your salary + distributions still face Kentucky's 3.5%. Run the numbers in our S-Corp election guide.

Ahmad Adil's Take: Kentucky's headline rate is genuinely good — 3.5% flat beats most of its neighbors. What eats founders is the layer they didn't model: the LLET floor, the occupational tax in their city, sales tax on services they assumed were exempt. My rule for Kentucky: build your P&L with all five layers from month one, and set aside 30–35% of profit for taxes until your first full year proves your real number. Surprises are the only tax you can fully avoid.
