The input for the 2024 AGI and filing status will not open in TurboTax unless your 2025 income is the reason that you are not qualifying for the Form 8936 Clean Vehicle Credit. So, if you do not have the option to enter that information but you still are not getting the credit, then there is most likely another reason.

To learn more about the qualifications to receive the credit, take a look at the following TurboTax help article:

In my case, my 2025 AGI is above the MFJ limit for the Previously Owned Clean Vehicle Credit, and my 2024 AGI is below the limit. So 2025 income is in fact the reason I don’t qualify under the current year test.

That’s why I expected TurboTax Online to open the prior year AGI input and populate Form 8936 Part I line 3a, but I’m not seeing that option in the interview.

Are there specific conditions or screens in the Used Clean Vehicle section that trigger the prior year income test?

No, there is nothing that you should be able to input differently to trigger the screen that would allow you to enter the 2024 AGI and filing status.

If you would be willing to share a diagnostic copy of your tax return then I can take a closer look to see if something else is causing the input to not be triggered. The diagnostic file 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 in to your account and be sure you are in your tax return.
Select Tax Tools in the menu to the left.
Select Tools.
Select Share my file with agent.
A pop-up message will appear, select OK to send the sanitized diagnostic copy to us.
Post the token number here.

Hi @AnnetteB6 I have done what you suggested, as I had the same issue. Reading back on forums from 2024/2025 this is a common issue. My reference # is 1339277 for my file and I would appreciate your help, Thank you!

Hi eunseokwak, thanks for finding this thread. I was the one who started it. I’ve already spent two hours on the phone with TurboTax support across two separate calls and still haven’t found a solution. If you happen to find a workaround, please post it here. Much appreciated!

Thank you for sharing your token number and diagnostic file. After taking a look at the tax return, I could not determine anything with regard to claiming the clean vehicle credit because there was no information entered about what vehicle was purchased. Without that section being completed with your details and answers to the questions presented, I cannot determine what the problem may be or what the possible solution could be.

Feel free to input that information and send another token number if you still need assistance.

Sorry about that. I just re-added my 8936 to try again and had no option to input my 2024 MAGI. My case is 1339364

@wenger317 I was on the phone yesterday for 30 minutes and the person kept telling me to go all the way to the end where you have to verify your 2024 AGI to file. I kept telling this person that it was not the correct answer but they had no other ideas. I really hope that TurboTax can find a solution as this looks like a long-running issue.

@AnnetteB6 Is there any update? If TurboTax cannot support entering 2024 MAGI I need to find a different way to file my taxes.

Thank you for providing your token number and diagnostic file. It was used to report this experience to the development team for further investigation and program changes. These changes are currently in process, but there is no estimated date of completion at this time. If further information becomes available, I will provide it here. Typically program updates are released once per week and are usually available on Fridays.

They fixed it!!!

If you go to deduction and credits > Clean Vehicle Credit (where you entered your purchase detail) > then press continue and another set of question appears asking about your 2024 income.

My amount owed to the IRS dropped by $4,000 as expected. I wonder how many people didn't self review the PDF copy of their tax return to catch TurboTax's mistake.

@AnnetteB6 can you help me with a discount code or refund for this issue?

I can't believe I'm paying them when I found the error myself.

After two separate phone calls with TurboTax support totaling more than two hours — where the reps had zero clue what was wrong or how to fix it — I was the one who had to discover the bug and the workaround on my own. Their software completely failed to trigger the 2024 AGI questions for the Previously Owned Clean Vehicle Credit.

It's ridiculous that customers have to troubleshoot and correct TurboTax's own programming errors, especially when it could have cost me $4,000.

@AnnetteB6 — any movement on the goodwill discount or partial refund I requested for this mess?

I do not have the permissions or ability to initiate any discounts or refunds. Thank you again for your patience in waiting for the development team to correct the situation so that you could file an accurate return.

Take a look at the following TurboTax help article to learn about the refund policy and how to request one:

I ended up filing a dispute with my card company after they denied my refund request. I didn’t wait for the fix, but paid for desktop where I could edit the form and add MAGI myself. What a wreck!
