A former Independence tax preparer was sentenced for preparing approximately 1,000 false tax returns.

Monique Hernandez, 52, was sentenced to four years and six months in federal prison without parole for her role in a conspiracy that resulted in nearly $700,000 of fraudulent refunds.

After an undercover IRS agent confirmed the fraudulent nature of the tax preparation business, federal agents executed a search warrant at the office of Complete Tax Service in 2014. According to the U.S. attorney’s office, after the search Hernandez and Warburton kept committing tax crimes for almost two more years, until January 2016, when the IRS revoked their tax preparation number.

A sentencing hearing for Warburton is scheduled for Aug. 30.
