My personal tax return extension was rejected after midnight last night. The email from turbotax says this: What do I do?

I made a payment to the IRS for anticipated taxes and filed an extension for personal taxes at 9 pm my time yesterday (4/15/25). I received an email at 1 am from turbotax after I filed my extensions but I was asleep: R0000-902-01 - Taxpayer TIN in the Return Header must not be the same as a TIN of a previously accepted electronic return for the return type and tax period indicated in the tax return. In most cases, you just need to submit a new extension application before the filing deadline. I don't know why the TIN is wrong or what to do to fix it. I had filed my business taxes prior under the same turbotax account, is that why? Does this mean I will be penalized for not filing the extension.

You have until 11:59 PM on April 21 to resubmit or mail your extension, if it was rejected. You should go back and make sure that your name, Social Security, and date of birth are correct.  If all is correct, you can mail in your extension.  

What if my federal extension was rejected?

@avadventurespllc 

from your post "   Taxpayer TIN in the Return Header must not be the same as a TIN of a previously accepted electronic return for the return type and tax period indicated in the tax return. "  says to me the rejection is because  you are using a TIN/SSN asking for extension  when  a return with the same TIN has been accepted for processing.

What do you mean a business  return using the same TIN.    A business return   cannot have the same TIN as the owner  if it has a separate existence ) because a  self-standing entity will be filed not on 1040.

You can see I am very confused as to what you have done -- please can you explain ?

At the same time ,and despite the rejection,  you can still file your return as soon as you are able to --  an accepted extension really does not change anything  as long as you file  before Oct. 15th  ( to avoid  failure to file penalty ).

Will circle back once I hear from you.

an individual extension is form 4868

if you have a social security number that is to be used

If you’re a nonresident or resident alien and you don’t have and
aren’t eligible to get an SSN, you must apply for an ITIN.

an ITIN is an individual tax identification number that is distinct from a business TIN or EIN.

@avadventurespllc  What business taxes did you file?  I don’t think you can file it under the same account.  Did you use the Windows Desktop download  Business program to file a business return?  Was it a 1065 or 1120 tax return?
