When E-filing your 2008 Federal taxes, you use the AGI (Adjusted Gross Income) from your 2007 Federal return as an "electronic signature". OK, simple enough.
So, naturally, if you filed an amended tax return for 2007 that changed your AGI, you use the correct, amended AGI.
Right?
Wrong.
This is the government we're talking about. You use the original, un-amended AGI. Even if it's wrong.
Because using the CORRECT AGI will cause the IRS to reject your return.
Your tax dollars at work out getting hookers and blow.
