The owner of a local drywall company was sentenced today for failing to pay taxes either personally or on behalf of his business, Drywall Perfections, Inc. (DPI), for tax years 2017–2022.

Esequiel “Tony” Terrazas Pacheco of Evansville, Wyoming, the owner of DPI, was sentenced to 18 months’ imprisonment with three years of supervised release for willful failure to file an income tax return and willful failure to account for and pay over tax. U.S District Court Judge Scott W. Skavdahl imposed the sentence on Feb. 3 in Casper. The court also ordered restitution to the Internal Revenue Service (IRS) in the amount of $766,744.28.

According to court documents, the defendant operated DPI from his home since 2015 and has never filed corporate or personal tax returns. Additionally, although a tax preparer prepared quarterly employer tax returns (Forms 941) for ten quarters between late 2019 and early 2022, the Defendant willfully failed to file Forms 941 or pay over the required quarterly taxes. The investigation also revealed DPI failed to employ any meaningful bookkeeping or accounting practices and failed to maintain sufficient records. IRS-CI investigated the crime.

“Mr. Terrasas Pacheco had multiple opportunities to accurately report and file his income taxes,” said U.S. Attorney Darin Smith. "Over a period of six years he willfully and knowingly defrauded the U.S. government and placed additional tax burden on the shoulders of hardworking taxpayers. Thanks to the outstanding investigative work of IRS-CI and our prosecutors, justice has been served.

“Esequiel Terrazas Pacheco is spending the next 18 months in jail and will be paying back the federal government for much longer than that,” said Amanda Prestegard, Special Agent in Charge, IRS-CI Denver Field Office. “His actions were motivated by greed with a complete disregard for his employees. We appreciate our partnership with the U.S. Attorney’s Office in helping us hold employment tax cheats accountable for victimizing not only the IRS, but their own dedicated workforce.”
