How to Find Out Why Your Return Was Rejected (Federal)

A rejected e-filed return means the IRS did not accept it for processing—so it’s treated as not filed yet until you correct the issue and resubmit (or file by paper). 

1) Get the rejection details from your e-file source (software or preparer)

The IRS sends the rejection back through the e-file acknowledgment system to the transmitter (your tax software provider or your tax professional). Your software (or preparer) should show a reject code and a short explanation. This message is your starting point for understanding what went wrong and how to fix it. 

2) Match the reject reason to the most common IRS causes and fix it

The most common taxpayer-facing rejection causes include: 

• Prior-year AGI or Self-Select PIN mismatch (identity validation failure) 

Re-enter the exact prior-year AGI or prior-year Self-Select PIN the IRS has on file. In some situations—like when your prior-year return is still unprocessed or you did not file a return for that year—the IRS instructs taxpayers to use 0 for the prior-year AGI. Always follow the current on-screen instructions in your software or IRS guidance for your specific case. 

• IP PIN missing or incorrect (if you’re in the IP PIN program) 

You must enter the current-year IP PIN correctly or the IRS will reject the e-filed return. If you’ve lost it, use the IRS “Get an IP PIN/Retrieve your IP PIN” tools or contact the IRS, then update the return and resubmit. 

• Name/SSN (TIN) mismatch or SSN already used 

This can mean someone already filed using that SSN, or that the name control/TIN combination doesn’t match IRS or Social Security Administration records. Double-check spelling, name changes, and the SSN against official documents; correct any errors and try again. 

• A required form is missing

 Some returns are rejected because a required form for your situation is missing. A common example is a return rejected for a missing Form 8962 in certain Affordable Care Act marketplace coverage situations. 

Your reject code message usually points to one of these categories. Fix the item in your software (or with your preparer) and resubmit the return electronically—most rejections are resolved this way on the second try. If you need an expert tax professional to assist you here, let us know and we’d have one of ours connect to you! 

3) If you can’t e-file after fixing it, you may file by paper—but watch the “timely filed” rule

If you decide (or are forced) to file by paper after an e-file rejection, the IRS has a special timing rule. Your paper return can still be treated as timely if it is mailed by the later of: 

• The original due date of the return (including any approved extensions), or 

• 10 calendar days after the IRS rejection notification date 

You should also include: 

• A brief explanation of why you are filing by paper after an e-file rejection 

• A copy of the e-file rejection notice 

• A short corrective history (what you tried to fix and when) 

This is especially important if you are close to a filing deadline or already on an extension. 

4) If the rejection suggests identity theft (SSN already used), take identity-protection steps

If the reject indicates a return was already filed under your SSN—or you suspect identity theft—follow IRS identity theft guidance right away. This usually involves contacting the IRS using the numbers in the notice, possibly filing an identity theft affidavit, and monitoring your tax account. Going forward, consider using or requesting an Identity Protection PIN (IP PIN) to help protect your account. If you already have an IP PIN and lost it, retrieve it through the IRS tools, then refile with the correct number. 

State return note 

State income tax returns are handled by each state’s revenue department separately. A federal rejection does not automatically mean your state return was also rejected (or accepted). Your software or preparer should show a separate state acknowledgment, and any state-specific reject reasons will come from the state tax authority. For better understanding and ensuring compliance, connect with our tax experts at Monily.
