Checking the mail in December is typically a pleasant experience, filled with holiday cards and packages.

Then comes January. Besides the Christmas bills, mailboxes begin to overflow with W-2s, 1099s, statements from financial institutions, and IRS forms. It's no wonder John Ulzheimer, president of consumer education for, calls January the most dangerous month for mail.

“January is a high-value month for thieves,” he said.

It's particularly easy for thieves to dip into someone’s mailbox, take the envelopes, and gain all the information needed to steal someone else’s identity.

How to best protect mail, short of meeting the mail carrier at the mailbox each day, is a significant challenge. You shouldn’t stop your mail because many items are time-sensitive. Creating an alternative delivery destination, like a P.O. box, could cause more trouble than it’s worth, said Ulzheimer.

The first step is to know what tax-related statements you should be receiving. For most people, the forms include a W-2, unearned interest statements from your bank, interest statements from your mortgage lenders, and possibly end-of-year retirement account statements. Independent contractors who receive 1099 statements should have a list of companies they’ve done business with.

Once you know what forms should be arriving, keep a tally of when they arrive. On February 1, note what is missing (independent contractors should remember that they may not receive a 1099 from everyone on their list, especially if the payment was less than $600).

“If you haven’t received them all by the end of January, then it’s time to pick up the phone and start calling the banks, your HR department, or anyone else who should have sent you documents. Find out if they were sent, when they were sent, confirm where they were sent, and see if perhaps they’re just going to be late,” said Ulzheimer.

If the tax document has been mailed and should have been received, it’s time to take action. Ulzheimer recommends contacting the credit bureaus and asking for a copy of your reports, which are free if you think you are a victim of fraud.

“You should be looking for recent ‘inquiries’ -- a record of who pulled your credit report and on what date,” Ulzheimer said. “If you see any new inquiries and you never applied for credit, then contact the company and let them know of the potential fraud.

“Also, at the same time you’re going to want to place fraud alerts on all of your credit reports and even go so far as to ‘freeze’ them, which is free in most states if you’ve been the victim of ID theft. This will prevent any new creditor from accessing your credit files without your pre-approval,” Ulzheimer added.

Even if nothing shows up on the credit scores immediately but the expected forms never arrive, Ulzheimer recommends continuing to monitor your credit or even issuing a credit freeze. The data may have been sold but not yet circulated.

Another common tactic is for thieves to wait a while, hoping the victim will forget that the information went missing and won’t be on alert for problems.
