Why this matters

If the IRS has the wrong SSN for you, refunds can be delayed, misapplied, or sent to the wrong record. Correcting the SSN with the Social Security Administration (SSA) and then amending your tax return is the practical way to recover any overdue refund and clear IRS records (see SSA guidance at https://www.ssa.gov and IRS guidance at https://www.irs.gov/forms-pubs/about-form-1040-x).

Step-by-step checklist

  1. Correct the SSN with the SSA first
  • Visit your local SSA office or use SSA instructions to update their records. Keep written proof of the correction (a corrected Social Security card or an SSA notice). The SSA explains required documents and steps at https://www.ssa.gov.
  1. Get corrected wage and information statements
  • If employers or payers issued W-2s or 1099s with the wrong SSN, ask them to send corrected forms (for W-2s this is Form W-2c). The IRS needs correct third‑party forms to match earnings to your corrected SSN.
  1. Prepare and file Form 1040‑X (amended return)
  • Use Form 1040‑X to correct the SSN and any tax items affected by the change. Include a clear explanation in Part III of Form 1040‑X that you corrected your SSN and note the date it was updated with the SSA. Attach corrected W‑2/W‑2c or 1099s. Check the IRS Form 1040‑X page for current filing options: https://www.irs.gov/forms-pubs/about-form-1040-x. Many taxpayers can e‑file amended returns using tax software, but paper filing is still common depending on the year and situation.
  1. Follow state tax rules
  • If you filed a state return that used the incorrect SSN, contact the state tax agency about amending that return. State procedures and forms vary.
  1. Track processing and expect delays
  • Amended returns can take longer than original returns. The IRS’s Where’s My Amended Return? tool shows status and is the official tracker: https://www.irs.gov/filing/wheres-my-amended-return. Expect processing to take roughly 8–16 weeks, sometimes longer during busy periods.

What to include with your amendment

  • A copy of SSA documentation showing the corrected SSN (keep originals; include copies if requested).
  • Corrected W‑2/W‑2c or corrected 1099s.
  • A written explanation of the SSN correction and dates.
  • Any other supporting schedules if the change affects income, credits, or deductions.

Common situations and tips from practice

  • Employer error: If an employer submitted wages under the wrong SSN, get a W‑2c. In my practice I’ve seen refunds stall until the employer files the W‑2c — follow up with payroll and keep records of requests.
  • Name changes: If you changed your name (marriage, divorce) and the SSA hasn’t updated records, the IRS may hold refunds. Update SSA records first to avoid repeat amendments.
  • Electronic filing: If your tax software supports e‑filing for 1040‑X for the tax year you’re amending, e‑filing can speed processing. Check the IRS Form 1040‑X page or your software vendor.

How long will it take to get the refund?

Processing times vary. The IRS indicates amended returns can take several weeks to months; use the Where’s My Amended Return? tool for status and expect roughly 8–16 weeks in typical cases. If your refund is delayed beyond that, consider contacting the IRS or a tax professional.

Interest on late refunds

If the IRS pays your refund late, interest may be due on the overpayment. The IRS publishes rules on interest for overpayments — see IRS guidance or ask a tax professional for specifics.

State refunds

State tax agencies operate separately. Even after the federal SSN correction and amended federal return, you may need to submit a state amended return and supporting documents to receive a state refund.
