Sales tax major purchase deduction not working properly

user17705932340 — Sun, 08 Feb 2026 23:37:18 GMT

When I enter the amount of sales tax paid on a major purchase, Turbo Tax Premier gives an error that the calculated rate does not match the rate for where I live ("Because of IRS regulations, you cannot deduct the sales tax paid on your Plumbing materials purchase because it was calculated using a rate that does not match the general rate for your location (0.0780)".) Even when entering a dummy transaction of $1000, with 78 dollars of tax (a 7.8% rate) I get the error.

If you would like to send us a “diagnostic” file that has your “numbers” but not your personal information it would help.  If you would like to do this, here are the instructions: (Don't forget to give us the state)

Then select Tools below Tax Tools.
A window will pop up which says Tools Center.

Reply to this thread with your Token number and your state. This will allow us to open a copy of your return without seeing any personal information.

@DianeW777 every time I try to send you the token in a message the system gives me an "invalid HTML" error and says I'm entering phone numbers. Suggestions how to get you the information? I've tried retyping it multiple times.

The rate is the issue and easy to misunderstand. I had tested this earlier and here is the solution for your return. When asked to put in your sales tax rate for your state you must enter it as a percentage and not a decimal.

Example: 7.8 versus .07800

Once this is completed your sales tax is calculated correctly and used as a deduction. Please update if your conclusion is different once the change is put in place.

I am getting the exact same error.

I have confirmed that I get this error with simple dummy numbers to match the tax rate.

I have also confirmed that I am allowed this deduction, by entering the total amount "as if" I had reciepts for all.

This is an error in the turbotax code.

please please please fix this. I am paying for this service and expect to be able to correctly fill out the forms, indicating that I only have one receipt for the large purchase.
