The feds have accused a Dallas tax preparer of falsifying deductions to keep customers from having to pay the proper amount of taxes.
Tax losses from the scheme cost the government as much as $60 million.
Preston didn't immediately return a message for comment.
Preston, at the end of each tax-filing season, allegedly held parties for employees and customers featuring strippers and prizes such as a car, a trip to Jamaica and $1,000 in cash.
The complaint accuses Preston of teaching her employees to fabricate businesses and improperly claim earned income tax credits.
