If your return came back with an IRS e-file rejection code, the return was never accepted — an automated check found a mismatch between what you entered and what the IRS has on file. Most rejections are fixable in minutes, and if you e-filed by the deadline you generally have five calendar days to correct and resubmit without a late-filing penalty. The code your software displays tells you exactly which field to look at.
How to Read Your Rejection Code
Every rejection comes with an alphanumeric code that follows a pattern. Codes starting with IND point to individual taxpayer identity verification: prior-year AGI, name, date of birth, or PIN. Codes starting with R0000 are broader validation rules covering things like zip codes and Social Security Number formatting. Codes prefixed with a form abbreviation (for example, FW2) tell you which attachment has the problem.
Your tax software usually translates the raw code into plain English, but when the explanation is vague, the code itself is the fastest thing to search on.
You Have Five Days to Fix It — Ten for Business Returns
This is the deadline most filers don’t know about. If your return was e-filed on time but rejected, the IRS gives you a short window, called the Transmission Perfection Period, to correct the error and resubmit electronically. For Form 1040 and Form 4868 extensions, that window is five calendar days. Business returns like Form 1120 and Form 1065 get ten calendar days.
The perfection period is not an extension of time to file. It’s a window to fix the technical error. Resubmit successfully inside it and the IRS treats your return as received on the date of the original rejected submission, so no late-filing penalty applies even though acceptance came after the deadline. Weekends and holidays don’t extend the window, so don’t push it to the last day.
Identity Verification Rejections
Identity mismatches are by far the most common reason returns get bounced. No human is reviewing your submission at this stage; the IRS runs your identifying information against its database and rejects instantly if something doesn’t line up.
Prior-Year AGI Doesn’t Match (IND-031, IND-032)
Your prior-year Adjusted Gross Income acts as your electronic signature. The number you need is the AGI from the return the IRS actually accepted last year — not a draft, not an amended return you filed later, and not a figure you’re recalling from memory. If you amended last year’s return after filing, the IRS database may still hold the original AGI.
A few situations trip people up. If you filed jointly last year but are filing separately this year (or the reverse), you still enter the AGI from whatever return the IRS accepted for the prior year. Newlyweds who each filed separately last year enter their own individual prior-year AGI. First-time filers, and anyone who didn’t file the previous year, enter zero.

Identity Protection PIN Missing or Wrong (IND-180 through IND-183)
The IRS uses two different PINs, and mixing them up is easy.
The Self-Select PIN is a five-digit number you choose yourself — any five digits except all zeros — that serves as your electronic signature. You pick a new one each time you file, and it works alongside your prior-year AGI.
2Internal Revenue Service. Topic No. 255 – Signing Your Return ElectronicallyThe Identity Protection PIN is a six-digit number the IRS assigns each calendar year to prevent someone else from filing under your Social Security Number. If you have an IP PIN — whether you requested one or the IRS issued one after an identity theft case — your return will be rejected if you leave it out or use last year’s number. The IRS generates a new IP PIN annually. Retrieve your current one through the IRS “Get an IP PIN” tool online.
3Internal Revenue Service. Get an Identity Protection PINName, SSN, or Date of Birth Mismatch (R0000-500-01, R0000-503-02, IND-525)
Your name, Social Security Number, and date of birth must exactly match Social Security Administration records. A maiden name where the SSA has a married name, a hyphen where there shouldn’t be one, or a transposed digit will all trigger a rejection. Code R0000-500-01 flags a mismatch on the primary taxpayer’s SSN or last name, R0000-503-02 flags the same for a spouse, and IND-525 means the primary filer’s date of birth doesn’t match.
If your legal name has changed through marriage, divorce, or a court order, you’ll need to update it with the SSA (Form SS-5) before the IRS will accept the return under the new name. Until the update posts, your options are to file using the name the SSA currently has on record or to file on paper.
Dependent and Filing Status Rejections
Someone Already Claimed Your Dependent
The IRS won’t accept two e-filed returns with the same dependent’s SSN for the same tax year. This happens with divorced parents who both claim a child, a college student who files first and then a parent tries to claim them, and occasionally with identity theft.
4Internal Revenue Service. Age, Name or SSN Rejects, Errors, Correction ProceduresYou cannot fix this by resubmitting electronically. If you’re confident you have the right to claim the dependent, file a paper return. The IRS will process both, determine who is legally entitled, and may contact one or both filers for documentation. Don’t attach extra proof to the paper return unless the IRS asks for it.
Head of Household Doesn’t Fit
Selecting Head of Household when the underlying facts don’t support it will trigger a rejection. To qualify you generally must be unmarried (or considered unmarried) as of December 31, have paid more than half the cost of maintaining your home for the year, and have had a qualifying person living with you for more than half the year. If the data on your return doesn’t support these conditions, switch to the correct status (usually Single or Married Filing Separately) and resubmit.
Missing Form 8862 After a Prior Disallowance
If the IRS previously reduced or disallowed your Earned Income Credit, Child Tax Credit, Additional Child Tax Credit, or American Opportunity Tax Credit for any reason other than a math error, you must attach Form 8862 the next time you claim that credit. Skipping the form gets the return rejected. The requirement applies to the EIC if it was disallowed for any year after 1996, and to the CTC, ACTC, or AOTC if disallowed for any year after 2015.

Beyond identity and dependents, the IRS checks the internal consistency of your return.
Missing or invalid identification numbers on business forms are a common culprit. A Schedule C without an Employer Identification Number when one is required, or a K-1 with a partner ID that doesn’t match IRS records, will trigger a rejection. Empty required fields do the same — the system treats them as an incomplete return.
Returns that require specific attachments will bounce if those forms are missing. If you reported capital asset sales without the supporting form containing the transaction details, the return won’t pass validation. Most tax software handles attachments automatically, but manual overrides or skipped interview questions can leave gaps.
Bank account errors work a bit differently. If you enter a routing or account number for direct deposit that fails validation, the IRS may reject the return or, in some cases, accept it and later send you a notice when the deposit fails.
6Internal Revenue Service. Refund InquiriesResubmitting Your Corrected Return
Once you’ve fixed the flagged field, look for a “Re-file” or “Resubmit” option in your tax software. Most commercial programs repackage the return for another attempt with a click. Expect an acceptance or rejection notification within about 24 to 48 hours, sometimes faster.
If the return is rejected a second time, read the new code carefully. Fixing one error can reveal another that was hidden behind it, because the IRS processes rejections sequentially. A return with three problems may need three rounds of correction, and each round eats into your perfection period.
When Paper Filing Is the Only Option
Paper becomes necessary in three situations: another filer already claimed your dependent’s SSN, the perfection period has passed, or your software has run out of resubmission attempts.
Your paper return must be postmarked by the later of two dates: the original due date of the return (including any extensions), or ten calendar days after the IRS notified you of the rejection. When you mail it:
- Write in red at the top of the first page: “Rejected Electronic Return – (Date)”
- Include a copy of the rejection notification from your software
- Briefly explain why the return is being filed after the due date
- Describe the corrective steps you took to resolve the e-file error
- Sign and date the return before mailing
The mailing address depends on which form you’re filing, what state you live in, and whether you’re including a payment. The IRS maintains lookup tables organized by form number.
7Internal Revenue Service. Where to File Paper Tax Returns With or Without a PaymentIf the rejection involved a duplicate dependent claim you believe is rightfully yours, file the paper return and claim the dependent as you normally would. The IRS will compare both returns and may send letters to both filers requesting documentation. The process often takes several months, but it’s the only route when the e-file system won’t let you through.
