To file individual returns electronically, the IRS requires the taxpayer to verify their adjusted gross income (AGI) from the prior year’s return. The electronic filing will be rejected if the AGI does not match IRS records. This rejection may be a fairly common issue given that as of April 1, the IRS has an inventory of more than 7 million unprocessed individual returns – they are likely missing a lot of taxpayers’ prior year AGI in their system.
The IRS website indicates that this problem can be resolved by entering a zero when posting the taxpayer’s prior year AGI. Apparently, the IRS does not try to reconcile the AGIs if a taxpayer indicates they did not have AGI in the prior year.
