The Internal Revenue Service today wrapped up its annual "Dirty Dozen" list of tax scams. Taxpayers need to guard against any ploys to steal their personal information, scam them out of money or talk them into engaging in questionable behavior with their taxes.

During the past year, as part of the Security Summit initiative, the IRS partnered with states and the tax industry to enhance coordination and create a more secure system for taxpayers. Participants now regularly share details of fraudulent schemes detected so both industry and government can provide increased protection. Many enhancements are invisible to taxpayers.

Taxpayers are encouraged to review the list in a special section on IRS.gov and be on the lookout for these scams. Many of these con games peak during filing season as people prepare their tax returns or hire someone to do so. The IRS this week also renewed a consumer alert for e-mail schemes after seeing an approximate 400 percent surge in phishing and malware incidents so far this tax season.
