Guard against tax fraud
File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.
Watch your financial accounts
Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.
Replace exposed ID documents
Contact your state DMV or the issuing agency about replacing an exposed driver's license, passport, or government ID number.
Secure your online accounts
Change the password on any account that reused an exposed password and turn on two-factor authentication wherever it's offered.
