Extreme Calculation error simple tax return

asdf1213 — Mon, 23 Feb 2026 12:04:44 GMT

I am married filing jointly. Our taxable income for the year is 101,712. Turbo tax is saying that we owe 8,602,706 in additional medicare tax, a tax that I believe we make less than the threshhold amount to pay regardless, much less paying 8x more than our income . I am not sure how it is coming up with this number, or how to correct for filing.

I am going to take a guess here but it sounds like you entered the figure for your income incorrectly. Go back and check what you entered. Did you add extra digits? Is the decimal in the proper place or is it missing altogether. If the program has the wrong data entered, it is going to return incorrect figures

Yes, calculations that far from a realistic number suggests that there was a problem with an input somewhere along the way. The best suggestion for what to do next is to follow the advice of user brenele and revisit your income items to check the accuracy of the inputs.

If you do not find something that was input that is causing this tax calculation, give another update here and someone will try to walk you through some other steps to try.

Also, if nothing seems out of place, clearing and starting over is always an option.

I went back through all of the income, and as far as I can tell, all of the figures were entered correctly, but am still getting the incorrect amount owed for federal.

You are correct. Based on your income and filing status you should not owe additional medicare tax on your return.

If you could try one last thing that may be helpful. In your situation, you should first clear your cache and cookies. It handles many issues that seem nonsensical on a regular basis.

Close your TurboTax return first.

Watch to be sure you are selecting 'all time' as example. Do not use selections like 'last hour' for those browsers that give you options.
