If you tried to file your taxes and you get rejected because your social security number has already been used to file a return, you need to take action fast. Someone else may have stolen your identity or knows you and decided they would try to cash in on your name. Don't sit by and let it happen. There are things that you can do if someone else used your social security number to file their tax returns.
Here are some of the steps you can take if you think someone has filed a tax return using your social security number:
Contact the IRS (Internal Revenue Service)
The first thing you will need to do is contact the IRS to find out for sure if someone has used your social security number to file their taxes. The other possibility is that they could have used your number to claim you as a dependent. Either way, no one is allowed to use your social security number for these purposes unless they have the right to do so. Once you have established whether someone has done it or not, you can move forward with the IRS to takes steps to get it reversed. The other person will be subject to IRS penalties.
Call Credit Companies/Banks
If someone used your social security number to file their taxes, they may have also attempted to charge on your cards or break into your bank account. Call your bank to make sure there have been no unauthorized uses on your accounts. If there have been, talk to you bank about the options you have to get the unauthorized transactions removed from your account.
Check Credit Report
Even if someone hasn't used the accounts that you already have, they may have tried to open accounts in your name. Check your credit report to make sure that no one has tried to do this. The sooner you find out there are financial issues out there, the sooner you can address them.
No one has the right to use your social security number. There are times that it might be permissible for them to claim you as a dependent, but you would know if someone had that right. Keep a close eye on your credit report and bank accounts. Don't let anyone destroy your credit or take what is yours when it comes to income taxes. You work hard for your money and you don't want anyone messing with that.
