Many (if not most) people and organizations approach a new year by setting new goals or implementing changes. This exercise, however, requires a reflection on the previous year’s events, successes, and failures. And government agencies are not exempt from taking time to reflect on the prior year’s accomplishments. IRS Criminal Investigation (CI) recently selected its “Top Ten Cases of 2021,” and the list involves quite a range of prominent investigations during the past tax year.

IRS CI, Generally

According to its mission statement, Criminal Investigation “serves the American public by investigating potential criminal violations of the Internal Revenue Code (IRC) and related financial crimes in a manner that fosters confidence in the tax system and compliance with the law.”[1] IRS CI’s four main strategies are compliance, money laundering, international, and terrorism.[2] Additionally, CI pursues investigations that align with its mission, considering factors, such as: whether the investigation is high profile, whether the investigation involves egregious allegations, the deterrent of the investigation, and conformity with the CI’s Annual Business Plan (ABP).[3]

Top Ten Cases of 2021

IRS CI selected the following ten cases as the top investigations of 2021:

  1. Owner of bitcoin exchange sentenced to prison for money laundering

Rossen G. Iossifov, a Bulgarian national, was sentenced to 121 months in federal prison for participating in a scheme where popular online auction and sales websites — such as Craigslist and eBay — falsely advertised high-cost goods (typically vehicles) that did not actually exist. Once victims sent payment for the goods, the conspiracy engaged in a complicated money laundering scheme where U.S.-based associates would accept victim funds, convert these funds to cryptocurrency, and transfer the cryptocurrency to foreign-based money launderers.

  1. Ex-pastor of Orange County church sentenced to 14 years in federal prison for orchestrating $33 million con that defrauded investors

Kent R.E. Whitney, the ex-pastor of the Church of the Health Self, was sentenced to 14 years in federal prison and ordered to pay $22.66 million in restitution to victims after defrauding investors of $33 million by orchestrating a church-based investment scam. At his direction, church representatives appeared on television and at live seminars to make false and misleading claims to lure investors to invest in church entities. Victims sent more than $33 million to the church and received fabricated monthly statements reassuring them that their funds had been invested, when in reality, little to no money ever was.

  1. Prairie Village Man Sentenced to 12 Years for $7.3 Million Dollar Payday Loan Fraud, $8 Million Tax Evasion

  1. DC Solar owner sentenced to 30 years in prison for billion-dollar Ponzi scheme

Jeff Carpoff, the owner of California-based DC Solar, was sentenced to 30 years in federal prison and forfeited $120 million in assets to the U.S. government for victim restitution after creating a Ponzi-scheme that involved the sale of thousands of manufactured mobile solar generator units (MSGs) that didn’t exist. He committed account and lease revenue fraud and purchased a sports team, luxury vehicles, real estate, and a NASCAR team with the proceeds. For more details on this case, click here.

The Ayvazyan family received sentences ranging from 17.5 years in prison to 10 months of probation for crimes ranging from bank and wire fraud to aggravated identity theft. The family used stolen and fictitious identities to submit 150 fraudulent applications for COVID-relief funds, based on phony payroll records and tax documents, to the Small Business Administration and then used the funds they received to purchase luxury homes, gold coins, jewelry designer handbags and more. Richard Ayvazyan and his wife Terabelian cut their ankle monitoring devices and absconded prior to their sentencing hearing; they are currently fugitives. For more details on this case, click here.


IRS CI was rather busy in 2021. Notably, CI’s top ten investigations included five cases based in California. Further, the investigations involved a range of activities, including operating bitcoin exchanges and applying for COVID-relief funds—activities that are garnering the attention of government and tax enforcement agencies. With a fresh new year, it will be interesting to see IRS CI’s new investigations and areas of focus, and taxpayers should be mindful of their tax and legal obligations, as well as potential criminal exposure.
