Identity Theft

Tax-related identify theft occurs when someone uses your stolen Social Security number to file a tax return claiming a fraudulent refund. While tax-related ID theft reported to the IRS fell by about 65% and the number of returns with confirmed instances of identity theft decreased by about 57%, it is still important to prevent becoming a victim of identity theft. Cybercriminals continue to steal the names, addresses, and Social Security numbers of millions of Americans. The IRS provides a Guide to Identity Theft to help you know the signs. If you believe that you are the victim of identity theft, contact our office or follow the Federal Trade Commission recommended steps by clicking here.
