Having your tax return rejected by the IRS can feel stressful, but it’s usually due to small, correctable mistakes. By double-checking personal details, using secure filing methods, and filing early, you can significantly reduce your chances of rejection. Leverage official IRS tools and don’t hesitate to seek help from a trusted tax professional if needed.
1. Mismatch in Personal Information
This is one of the most common reasons for IRS rejections. If your name, Social Security Number (SSN), or date of birth does not exactly match the records held by the Social Security Administration (SSA), the IRS cannot process your return.
How to Avoid It:
- Cross-check your SSN and full name with your Social Security card.
- If you’ve recently changed your name (due to marriage, divorce, etc.), update the SSA first.
- Be careful when entering your info — even a minor typo can cause a mismatch.
Pro Tip: Use tax software that flags inconsistencies or auto-fills data from last year.
2. Incorrect Dependent Information
Claiming dependents? Great! But if their SSN or full name doesn’t match SSA records, or if another person claims the same dependent, your return could be rejected.
How to Avoid It:
- Always double-check your dependent’s name and SSN from their SSA card.
- Talk to ex-spouses or other guardians to prevent duplicate claims.
- If your child filed a return claiming themselves, coordinate to fix the error.
Remember: Only one taxpayer can claim a dependent per year — even in shared custody situations.
3. Duplicate Tax Return Filed
If your SSN has already been used for a tax return this year, the IRS will reject any additional returns with that number. This could be a simple mistake or a sign of identity theft.
How to Avoid It:
- File early to beat scammers who use stolen SSNs.
- If you suspect fraud, contact the IRS Identity Protection Specialized Unit.
- Apply for an Identity Protection PIN (IP PIN) from the IRS. This 6-digit number protects your SSN from unauthorized filings.

4. Incorrect Prior-Year Adjusted Gross Income (AGI) or PIN
Your prior-year AGI or self-selected PIN is used to verify your identity when e-filing. If you enter it incorrectly, your return may be rejected.
How to Avoid It:
- Find your AGI on Line 11 of last year’s Form 1040 or retrieve it using the IRS transcript tool.
- If you used a different tax software last year, confirm the AGI matches what the IRS has.
- Keep a secure record of your PIN for future use.
Tip: First-time filers or those who used the non-Filer tool should enter “0” for AGI.
5. Unsigned Return
It may seem obvious, but forgetting to sign your return — whether it’s paper or electronic — makes it invalid. The IRS treats unsigned returns as incomplete and Un processable.
How to Avoid It:
- If you’re mailing your return, sign all required fields, including your spouse’s if filing jointly.
- For e-filing, complete the digital signature process (which may include entering your AGI or PIN).
- Carefully review all steps before submitting your return.
General Tips to Prevent IRS Rejections
- Use trusted tax filing software like TurboTax, H&R Block, or IRS Free File.
- Double-check names, numbers, bank details, and signature fields.
- File early to reduce the chance of ID theft or missed deadlines.
- Keep your SSA records updated.
- Save copies of everything: W-2s, AGI, PINs, and confirmation pages.
