It’s always important to protect your Social Security number (SSN), but it’s extra important to do so around tax time. The tax forms you receive (job, banks) and your tax returns will all have it on them, but you can take some steps to protect your SSN and safeguard yourself against identity theft.

The Gramm-Leach-Bliley Act (GLB)—also known as the Financial Services Modernization Act of 1999—repealed laws that prevented the merger of banks, brokerage companies and insurance companies.

It is a good idea to get a MIB report if you’re applying for private life, long-term care or disability insurance. MIB reports contain medical and prescription drug history information and may affect the the price you pay for insurance (or even your ability to get it).

A ChexSystems report contains information on banking/check writing history, so it’s a good idea to get one if you’ve had problems with your checking/savings accounts or are a victim of identity theft and someone else has written/cashed checks on your account.
