What Cryptocurrency Transaction Reporting Rules Apply in New York?

Cryptocurrency exchanges operating as Money Services Businesses (MSBs) must:

• Register with FinCEN (31 U.S.C. § 5330) before conducting any cryptocurrency transactions
• File a Currency Transaction Report (CTR) for any cash transaction exceeding $10,000
• File a Suspicious Activity Report (SAR) for any cryptocurrency transaction of $5,000 or more that raises money laundering, fraud, or structuring concerns (31 CFR § 1022.320)

Failure to register as an MSB is a separate federal offense, independent of any reporting failure.

Every virtual currency business operating in New York must obtain a BitLicense under 23 NYCRR Part 200. Holders are required to:

• Maintain a written AML compliance program with ongoing transaction monitoring
• File SARs with the NYDFS in addition to federal FinCEN filings
• Retain all cryptocurrency transaction records for a minimum of five years
• Submit to periodic NYDFS examinations and produce records on demand

I have worked with many clients who assumed federal MSB registration satisfied their New York obligations. It does not. The NYDFS enforces its own reporting framework independently and with equal rigor.

The obligation to file a CTR or SAR arises at transaction initiation, not at final settlement. Cryptocurrency transactions may be delayed by network congestion, custodial holds, or smart contract execution conditions, but those delays do not postpone the filing deadline. NYDFS examiners treat a delayed compliance assessment as substantively equivalent to a missed filing.

Unexplained settlement gaps in cross-border cryptocurrency transactions are treated as independent AML compliance red flags during FinCEN and NYDFS reviews. For every delayed transaction, maintain a live log that records:

• Initiation date and expected settlement window
• Actual settlement date
• Documented reason for any gap

Retroactive reconstruction of settlement records after a regulatory inquiry rarely meets the NYDFS documentation standard. I strongly recommend treating this log as an ongoing compliance document, not a retrospective one.

When the remitting or receiving party is a legal entity, financial institutions must identify and verify under 31 CFR § 1010.230:

• Any individual owning 25% or more of the entity
• The individual exercising operational control

A cryptocurrency transaction that bypasses beneficial ownership verification creates independent BSA liability for the processing institution.

BitLicense holders handling higher-risk third-party cryptocurrency transactions must:

• Obtain written AML compliance representations from each intermediary
• Conduct periodic reviews of all third-party relationships
• Escalate before execution any transaction lacking a clear, documented business rationale

Proactively mapping third-party relationships before a transaction begins is consistently more defensible in NYDFS examinations than attempting to reconstruct them after a suspicious pattern has been flagged.

Any person or entity engaging in virtual currency business activity on behalf of another person in New York must hold a valid BitLicense (23 NYCRR Part 200). Operating without one may also constitute unlicensed money transmission under New York Banking Law § 641, carrying criminal penalties entirely separate from any BSA exposure.

Breaking a larger cryptocurrency transaction into smaller ones to evade CTR or SAR filing requirements is a federal crime under 31 U.S.C. § 5324, commonly referred to as "smurfing." Key points:

• The offense is complete at the point of intent, even if the structuring is incomplete
• Penalties: up to $250,000 per occurrence and up to five years imprisonment
• The government may pursue civil asset forfeiture as a parallel remedy, without a criminal conviction

Any cryptocurrency transaction touching a person, entity, or jurisdiction on the OFAC Specially Designated Nationals (SDN) list triggers strict liability under IEEPA, regardless of whether you knew of the sanctioned status. Screen every counterparty and platform against the current SDN list before executing any international cryptocurrency transaction. Good-faith ignorance is not a defense.

Because these penalties apply per violation, a series of unreported cryptocurrency transactions can accumulate liability that exceeds the total operating capital of a business.

The NYDFS may impose any combination of the following against BitLicense holders:

• Civil monetary penalties scaled to the severity and duration of the violation
• Independent compliance monitor, retained at the licensee's expense for an extended period
• BitLicense revocation, which permanently prohibits all virtual currency business activity in New York

Recent NYDFS enforcement actions against major cryptocurrency exchanges for AML program deficiencies have resulted in penalties reaching into the hundreds of millions of dollars.

Direct fines are only part of the exposure. Violations also affect:

• Banking relationships and access to correspondent accounts
• Insurance coverage, which may be rescinded upon disclosure of an enforcement action
• Investor confidence and capital availability
• Personal liability for directors, officers, and compliance personnel for willful oversight failures

If you have any concerns about whether your current compliance program meets New York's requirements, consulting with an attorney before a regulatory examination begins is the most cost-effective step available to you.
