After you file

The IRS notice says LTR 12C.  "It says "Form 8880 is incomplete or missing from your return.  Complete the form with information that supports $[value] on line 51, Schedule 3.  Also attach all supporting forms on schedules, as required."

 

The 8880 I have now printed has the amount  deferred to her 401k correctly from her W-2, the correct percentage for the credit based on her income, etc.  In fact, it is essentially identical to the 8880 from the prior tax year.  So I think our plan is to mail in the 8880 and see what happens.  Her return is very simple and has not changed in any meaningful way from the prior tax year.

 

Thanks for any insights you might be able to offer.
