Woman gets 18 months for false tax return over $2.6m in unreported income tied to $16m crypto case

The count Au pleaded to covers about a sixth of the money prosecutors say she handled. They describe roughly $16 million of illicit funds spent on cryptocurrency she bought for Adam Iza. Against that sits $2.6 million of deposits that reached her personal accounts between 2020 and 2023 and never reached a tax return, a ratio of about 16 percent. Restitution comes to about 57 percent of that unreported income.

Prosecutors wrote in a sentencing memorandum that Au "concealed entities and income from her tax preparer and filed returns reporting only a small fraction of what she had actually received... Those were affirmative acts designed to prevent the IRS from learning the true extent of her income."

The methods were conventional too. At Iza's direction she formed shell companies and opened bank accounts in their names. Money not paid to the deputies went into real estate, vehicles, jewelry, clothing and almost $10 million of leisure spending by the couple.

The forfeiture order reaches tangible property. IRS Criminal Investigation and the FBI ran the case, and one of the former deputies was sentenced to 21 months earlier this month, three months more than Au received.

What the government charged is money that landed in a US bank account and then went missing from a return. The $16 million of cryptocurrency purchases appears in the prosecutors' account as description of the scheme. Iza pleaded guilty in Los Angeles in January 2025 to conspiracy against rights, wire fraud and tax evasion, and he has been in federal custody since September 2024.

The reporting machinery that would make the on-chain leg chargeable on its own terms is still thin. Chainalysis put potentially taxable on-chain activity worldwide at a minimum of $457 billion in 2025 and said CARF-covered events were about 14 percent of it. That is roughly $64 billion inside the net and $393 billion outside. Collection under CARF began on January 1, 2026 across 48 jurisdictions, Cryptopolitan reported. TRM Labs recorded $158 billion of illicit flows in 2025, up nearly 145 percent, which implies about $64 billion in 2024. At 1.2 percent and 1.3 percent of attributed on-chain volume, the denominator grew from roughly $5 trillion to roughly $13 trillion.

In my view the capability on display is old: bank records, a false return, a list of cars and handbags. The counter-argument comes from the same records. Au was reachable because she volunteered a bank account and a tax preparer, and an operator who keeps proceeds on-chain and spends them there generates none of the documents this case was built on. Two other readings survive the evidence. The investigation may have opened on the serving sheriff's deputies on Iza's payroll; and from this year CARF filings give the IRS a second entry point that did not exist when Au was depositing. What would settle it is a US tax case whose charged income is documented by exchange reporting with no domestic deposit behind it.
