What does the IRS Rejection code of my personal extension mean?

Understanding IRS Rejection Codes

When your e-filed extension is rejected, the IRS assigns a numeric or alphanumeric code (sometimes called a tax return code). These codes may look confusing, such as error code 428 IRS, error code 6000 IRS, or IRS error code 9998, but each has a specific meaning tied to the information submitted on your return.

Common personal extension rejections include mismatches in Social Security Numbers, names, or address formats. Business extensions may reference other codes like F7004-905-03, but for personal Form 4868, you’re most likely to see codes beginning with “R0000.”

Examples of IRS Rejection Codes

Error-f4868-R0000-092-02

IRS Rejection Code R0000-092-02

‘PrimarySSN’ in the Return Header must be within the valid range of SSN/ITIN and must not be an ATIN.

Explanation: The primary taxpayer’s SSN or ITIN is not valid. Contact the Social Security Administration (SSA) at 1-800-772-1213 or the IRS at 1-800-829-1040 to verify official records.

Error-f4868-R0000-117-01

IRS Rejection Code R0000-117-01

If the Filer has a US address in the Return Header and ‘StateAbbreviationCd’ is "AA", "AE" or "AP" then the ‘CityNm’ must be "APO", "DPO" or "FPO".

Explanation: If you use AA, AE, or AP for the state code, you must list APO, DPO, or FPO for the city. This commonly occurs for overseas military addresses.

Error-f4868-R0000-500-01

IRS Rejection Code R0000-500-01

‘PrimarySSN’ and ‘PrimaryNameControlTxt’ in the Return Header must match the e-File database.

Explanation: The taxpayer’s name and SSN do not match IRS records. This is one of the most frequent causes of rejection.

Error-f4868-R0000-503-02

IRS Rejection Code R0000-503-02

‘SpouseSSN’ and the ‘SpouseNameControlTxt’ in the Return Header must match the e-File database.

Explanation: The spouse’s SSN and name do not match IRS records. Verify details with the SSA or IRS before resubmitting.

Other codes taxpayers sometimes see on transcripts include IND-031-04 reject code, IND-452 reject code, IND-517-02, and IND-901 rejection code. These are usually tied to inconsistencies in income documents, filing status, or prior year AGI mismatches.

Common Questions

How will I know if my tax return is rejected?

You’ll receive an IRS notification with a specific rejection code. For extensions, this usually arrives quickly after filing.

What does it mean when your tax return is rejected?

A rejection means the IRS system flagged an error—commonly mismatched SSNs, names, or filing information. It does not mean your return is audited; you just need to correct the issue and refile.

What happens if your taxes are rejected?

You must fix the error and resubmit. If the deadline passes while your return is rejected, you may incur late-filing or late-payment penalties unless corrected promptly.

What to do if tax return is rejected?

Read the rejection notice carefully. It will list the error code (e.g., IRS error code 6101 or IRS error code 9998) and instructions to correct the problem.

Why would the IRS reject my return?

Reasons include incorrect SSN or name control, mismatched W-2s or 1099s, prior year AGI mismatches, or errors in address formatting. Questions like “why was my federal return rejected?” or “why would IRS reject tax return?” almost always tie back to data entry mismatches.

Bottom Line

IRS rejection codes help identify and fix problems with your extension or return. While codes like R0000-500-01 and R0000-503-02 are most common, others such as IND-452 or IRS error code 9998 may appear. Always review the rejection notice, correct the information, and re-file promptly.
