PTET election available retroactive to 2022.
The PTET election allows pass-through entities (S-Corps, partnerships, LLCs taxed as partnerships) to pay state income tax at the entity level rather than the individual level. This effectively converts the state tax payment into a business deduction that bypasses the $10,000 federal SALT deduction cap.
For Kentucky business owners with significant state tax liability, this election can save thousands to tens of thousands in federal taxes annually.
Learn About SALT Planning →Without the election, your state taxes are limited to the $10,000 SALT deduction cap on your personal return. With the PTET election, the entity pays the tax and deducts it as a business expense with no cap. You receive a credit on your state return to avoid double taxation.
Beyond income tax, Kentucky business owners need to account for these additional tax obligations and structures.
