1. File your taxes online ASAP before a criminal files for you and gets your refund.
2. Protect all children as explained in this blog:
A child’s Social Security number can be used by identity thieves to apply for government benefits, open bank and credit card accounts, apply for a loan or utility service, or rent a place to live. Why would ID thieves wish to assume a child’s identity? Because that child is (likely) a clean slate, which translates to plenty of available credit down the road. In addition, minors generally aren’t in the habit of checking their credit reports or even the existence of one, and most parents don’t find out about the crime until the child approaches the age of 18 (or well after).
A 2012 report on child identity theft from the Carnegie Mellon University CyLab delves into the problem of identity thieves targeting children for unused Social Security numbers. The study looked at identity theft protection scans done on some 40,000 children, and found that roughly 10 percent of them were victims of ID theft.
