2025 MO-A Itemized deduction

smontalban001 — Mon, 06 Apr 2026 20:57:28 GMT

It appears the Turbo Tax MO-A is adding back too much in state tax deductions to MO itemized deductions when the taxpayer has phased down federal state and local income tax deductions from $40,000 to $10,000 due to AGI on their federal Schedule A. When adding back the portion of state tax deductions due to income taxes, TurboTax starts with $40,000 instead of $10,000.

Was this issue resolved?

If not, I would like to take a deeper look at this. However, I need a diagnostic file which is a copy of your tax return that has all of your personal information removed. You can send one to us by following the directions below:

TurboTax Online:

Sign into your online account.
Locate the Tax Tools on the left-hand side of the screen.
A drop-down will appear. Select Tools
On the pop-up screen, click on “Share my file with agent.”
This will generate a message that a diagnostic file gets sanitized and transmitted to us.
Please provide the Token Number that was generated in the response.

TurboTax Desktop/Download Versions:

Open your return.
Click the Online tab in the black bar across the top of TurboTax and select “Send Tax File to Agent” *
This will generate a message that a diagnostic copy will be created. Click on OK and the tax file will be sanitized and transmitted to us.
Please provide the Token Number (including the dash) that was generated in the response.

*(If using a MAC, go to the menu at the top of the screen, select Help, then, “Send Tax File to Agent”)
