Frequently Asked Questions
Should I elect Missouri PTET in 2026 now that the federal SALT cap is $40,000?
Yes, in most cases where Missouri state income tax plus personal property tax exceeds $40,000, where household MAGI exceeds $500,000 (triggering the 30% SALT phase-down torpedo), or where taking the $32,200 MFJ standard deduction while deducting Missouri PTET at the entity level produces a larger combined federal deduction.
What is the 2026 Missouri PTET election deadline?
In Missouri, the statutory election / payment rule is: Return Due Date. Cash-basis entities must remit PTET payments by December 31, 2026 to claim the federal deduction on the 2026 return.
