Officials are warning taxpayers to stay vigilant against the most common tax scams called “The Dirty Dozen.”

Almost 2.7 million taxpayers file their tax returns in the final month leading up to the deadline on April 15. That’s why scammers use this time to target victims by phone or email, hoping to receive their private information. The scammers will then use it to file taxes under your name and identity.

“Many times criminals will pose as a government entity or an official business,” said Dan Hassell, Pennsylvania Revenue Secretary. He added, “If you are contacted through the mail, phone or email, do not provide personal information or money, until you are absolutely certain that you are speaking to a legitimate representative.”

Hassel also recommends not opening any unusual links or attachments in emails.
