A national crackdown on tax-related identity theft last week targeted more than 100 people and led to 58 arrests, according to the IRS and other federal officials.
The IRS said it was also stepping up internal reviews to spot false tax returns, and working to help victims of identity theft refund schemes.
IRS Commissioner Doug Shulman said the crackdown "sends a strong, unmistakable message to anyone considering participating in a refund fraud scheme this tax season.
