The IRS has released all twelve of the Dirty Dozen tax schemes to look out for during the 2015 filing season.

The Dirty Dozen listing, compiled by the IRS each year, lists a variety of common scams taxpayers can encounter at any point during the year. But many of these schemes peak during filing season as people prepare their tax returns.

Identity theft, phone scams, and phishing lead the list this year. Other issues include impersonation of charitable organizations, false income, expenses, or exemptions, and abusive tax structures.
