Kentucky LLC structure and cost: a flat 3.5% income tax that hides an entity-level tax and a local net-profits tax on top

Kentucky advertises a simple, falling flat income tax, and that part is true: the rate is 3.5% for 2026, down from 4.0%, on a multi-year path the legislature has tied to revenue triggers and pointed toward zero. But the flat rate is only the top layer. Underneath it, Kentucky taxes the LLC itself through the Limited Liability Entity Tax, which even a federally disregarded single-member LLC has to file, and cities like Louisville and Lexington add a local net-profits tax on business income. So the real cost of operating a Kentucky LLC is not the 3.5% headline; it is the stack. Take the income tax and the LLET first, then the local layer.

The flat tax, and the entity-level tax beneath it

Start with the two state-level taxes, because most people see only one of them.

Kentucky taxes individual income at a flat 3.5% for 2026, so an LLC’s income passes through to its members at a single, falling rate.

A standard Kentucky LLC is a pass-through, so its income lands on the members’ returns at the flat 3.5% rate for 2026, reduced from 4.0% under a reform that steps the rate down as revenue targets are met. There is no local sales tax to layer on, and the state sales tax is 6%. On income alone, Kentucky is competitive. But Kentucky also taxes the entity.

The LLET taxes the LLC itself on its Kentucky gross receipts or gross profits, with a $175 minimum, and even a federally disregarded single-member LLC has to file it.

Under KRS 141.0401, Kentucky imposes the Limited Liability Entity Tax on the LLC as an entity, calculated as the lesser of $0.095 per $100 of Kentucky gross receipts or $0.75 per $100 of Kentucky gross profits, with an absolute minimum of $175. Beginning in 2026, an LLC with under $100,000 of gross receipts is exempt, which spares the smallest companies, but any LLC above that pays at least the $175 minimum. The feature that catches people is that the LLET applies to the entity regardless of how the IRS treats it: a single-member LLC that is a disregarded entity for federal tax still files a Kentucky LLET return, Form 725, and owes the tax. The softening detail is that the LLET generates a credit against the members’ Kentucky income tax, so for a profitable LLC it is not pure double taxation, but the filing obligation and the minimum are real, and they surprise owners who assumed a disregarded LLC owed Kentucky nothing at the entity level.

The local net-profits tax most owners forget

Here is the third layer, and it is the one that makes the 3.5% headline misleading for a real operation.

Kentucky cities and counties tax business net profits directly, so an LLC operating in Louisville or Lexington owes a local tax of about 2.2% on top of the state.

Kentucky lets cities and counties levy occupational-license taxes, which include a tax on the net profits of a business operating in the jurisdiction, not just a payroll tax on wages. Louisville and surrounding Jefferson County reach roughly 2.2%, Lexington-Fayette County is 2.25%, and other cities have their own rates. For an LLC that owns and operates rental property in one of those jurisdictions, that local net-profits tax applies to the business income on top of the state’s 3.5% and the LLET. So a Kentucky rental LLC in Louisville faces three layers, the state income tax at the member level, the LLET at the entity level, and the local net-profits tax, which together are meaningfully more than the flat 3.5% headline implies. This is the seam a CPA watching only the state return can miss, and it belongs in the decision about where in Kentucky to operate and how to structure. Property held in a rural county with no occupational tax avoids the local layer that a Louisville property cannot.

Moving property in, and the missing series

On retitling and structuring, Kentucky is cheap in one respect and limited in another.

Kentucky’s real estate transfer tax is only about 0.1% of value, so moving property into an LLC costs little at recording.

Under KRS 142.050, Kentucky’s real estate transfer tax is $0.50 per $500 of consideration, about 0.1%, paid by the grantor and collected by the county clerk on recording. That is low, well below a percentage transfer tax like Maryland’s, so the recording cost of moving a property into a Kentucky LLC is small, though the exact treatment of an owner-to-entity transfer should be confirmed at the county clerk. What Kentucky does not offer is a series LLC.

Kentucky has no series LLC, so an investor holding several properties uses a separate LLC for each, and each carries its own annual report and LLET filing.

Kentucky’s LLC act has no series provisions, so the one-entity-with-internal-series structure available in Oklahoma or Utah does not exist here. Each property an investor wants insulated goes in its own LLC, and each of those is a separate filer with its own $15 annual report and its own LLET return. The series LLC guide covers the form Kentucky lacks; the Kentucky point is that a multi-property plan is several separate LLCs, and given the veil concerns on the protection page, each one should be genuinely capitalized and separately run rather than a thin shell.

The bottom line

Kentucky taxes individual income at a flat 3.5% for 2026, down from 4.0%, on a path toward zero, so an LLC’s income passes through at a low, falling rate.

The LLET taxes the LLC itself on its Kentucky gross receipts or profits with a $175 minimum, and even a federally disregarded single-member LLC files Form 725, though the tax credits against the members’ income tax.

Cities like Louisville and Lexington add a local net-profits tax of about 2.2% on business income, so a Kentucky rental LLC there faces three layers, not just the 3.5% headline.

The real estate transfer tax is about 0.1% of value, so moving property into an LLC costs little at recording.

Kentucky has no series LLC, so multiple properties mean multiple LLCs, each with its own annual report and LLET filing.
