Don't Trust Email? Protect Your Snail Mail Too
When you mail your tax return to the IRS, make sure it is mailed from a secure location like the post office or an official USPS collection box. Don't let it sit in the box overnight, because it could be stolen. For extra peace of mind, use certified mail.
"Someone could break into the box overnight and steal your information," Feinman said. "Or, if you're sending a check, they could take that and try to cash it."
