Why Are Returns Rejected?
Returns can be rejected for a range of reasons. For tax year 2023, the top e-file rejection reason was a prior-year PIN or adjusted gross income not matching IRS records, followed by missing Form 8962, an invalid Identity Protection PIN, duplicate filing, and a primary name mismatch.
Other common issues include missing or inaccurate personal information, such as a name or number that does not match IRS records. For example, taxpayers who change their name after marriage must update their information with the Social Security Administration to avoid discrepancies. Even minor typographical errors can trigger a rejection.
Returns may also be denied if the IRS has already accepted a filing under the same Social Security number or taxpayer identification number, which in some cases could signal fraud or identity theft. The IRS advises contacting the agency immediately and, if identity theft is suspected, filing Form 14039 and considering a fraud alert with credit bureaus.
Another frequent issue arises when a dependent—such as a child—has already been claimed on another return. This can occur in situations involving divorced parents or when a dependent files their own return and claims themselves.
Returns may also be rejected if an electronic signature cannot be verified. When filing electronically, taxpayers must provide their adjusted gross income from the previous year or an Identity Protection PIN. If the information does not match IRS records, the return is likely to be declined.
