How to Fix a Social Security Number on Taxes

Amending a tax return is essential if the Social Security number is wrong.

Mistakes on taxes are tough to avoid completely. This is especially true if you have complicated returns. Self-employed taxpayers often have complex and involved returns, and staring at tax forms can take its toll. If you made a mistake and entered the wrong Social Security number, you need to amend your return. This process is normally fairly easy.

Things You'll Need

• Blank 1040X

Instructions

1. Review the tax return you filed to verify the Social Security number (SSN) error. You should also double check the SSNs for your spouse and dependents (if applicable). Make sure the SSN(s) are inaccurate, make a copy of your return and circle the wrong SSN.

2. Obtain a blank 1040X form from the IRS (see Resource 1). The 1040X is the official form required to amend a standard 1040 return. This is for individual taxpayers, not businesses.

3. Fill in the 1040X completely, even if only the SSN is inaccurate. Copy over all of your income, address and name information. Double-check all figures. Make sure the correct SSN is reflected on the 1040X return. If you want, you can have your accountant double-check your figures, too.

4. File the 1040X. You must send it in to your local IRS office (see Resource 2). Make sure that you make a copy for your own records, though. You should also call ahead and give your local tax collector a heads-up.

5. Call a week after you send in your 1040X. Confirm its arrival. A SSN error is serious--your taxes could be deemed late and you may suffer penalties if you do not file the 1040X in a timely fashion. You must verify that it's been received and reviewed.
