Las Vegas tax preparer pleads guilty to filing false tax returns for clients
LAS VEGAS (KLAS) — A Las Vegas tax return preparer pleaded guilty to filing false tax returns for clients, resulting in at least $550,000 in tax loss, according to the U.S. Department of Justice.
Keisy Altagracia Sosa pleaded guilty Wednesday to one count of aiding and assisting in the preparation and filing of a false tax return.
Since at least 2007, Sosa has operated National Tax Service, a tax return preparation business in Las Vegas. According to court documents and statements made in court, from 2016 to 2021, Sosa prepared and filed with the IRS false tax returns on behalf of clients.
The tax returns falsely claimed dependents, claimed fictitious Schedule A expenses, such as sales taxes paid and unreimbursed employee expenses and claimed fictitious Schedule C expenses purportedly associated with a business operated by the taxpayer, the DOJ said.
The IRS sent multiple letters notifying Sosa that the returns that she filed appeared inaccurate and that she may not have met her due diligence requirements. The letters also reminded her of those obligations and directed her to resources with more information about those obligations. However, after receiving the letters, Sosa continued to prepare false returns, according to the DOJ.
Sosa's sentencing is scheduled for June 11 and the maximum statutory penalty is three years in prison as well as a period of supervised release and monetary penalties.
The DOJ wants to remind taxpayers to remain vigilant against unscrupulous tax preparers. Tax preparers that promise larger refunds than their competition may place taxpayers at risk of being part of a criminal scheme. The IRS urges all taxpayers to verify that the information on their tax returns is correct before filing.
