FinCEN moves forward on whistleblower payments

The U.S. Department of the Treasury’s Financial Crimes Enforcement Network (FinCEN) took a significant step on March 30, 2026, by proposing rules to pay whistleblowers who report certain financial crimes. The proposal, now submitted as a Notice of Proposed Rulemaking (NPRM), outlines how individuals can receive awards and protections for reporting violations tied to the Bank Secrecy Act, sanctions programs and other laws that protect the U.S. financial system.

For tax professionals, this development is more than a regulatory update. It signals a stronger enforcement environment and creates new considerations when advising clients. 

What the proposed rule does 

The proposed rule establishes a formal structure for FinCEN’s whistleblower program. While the program already exists under prior legislation, including the Anti-Money Laundering Act of 2020 and the Anti-Money Laundering Whistleblower Improvement Act of 2022, this proposal fills in the operational details.

Key provisions include:

• A process for submitting tips securely and applying for awards 
• Clear eligibility rules for whistleblowers 
• Awards ranging from 10% to 30% of collected monetary penalties 
• Protections against retaliation for individuals who come forward 

In short, FinCEN is creating a system that not only encourages reporting but also rewards it in a meaningful way.

What was in place before

Prior to this proposal, the whistleblower program existed in law but lacked detailed guidance. Individuals could submit tips, but there was uncertainty around how awards would be calculated, how claims would be reviewed and what protections were firmly in place.

That uncertainty likely discouraged participation. Without clear procedures or confidence in the outcome, potential whistleblowers may have had less incentive to take the risk. This proposed rule changes that by offering structure, transparency and financial motivation.

Why this change matters

The federal government continues to prioritize combating illicit finance, including fraud, money laundering and sanctions evasion. These activities often intersect with tax compliance issues, especially when unreported income or hidden assets are involved.

By strengthening the whistleblower program, FinCEN is expanding its reach. Regulators are no longer relying solely on audits and investigations. They are actively encouraging insiders to provide actionable information. This approach has worked in other areas, such as IRS whistleblower programs and Securities and Exchange Commission (SEC) enforcement. FinCEN is now aligning with that model.

How this benefits everyday taxpayers

At first glance, this may seem like a policy aimed only at large financial crimes. However, it has broader implications. A stronger enforcement framework helps ensure that all taxpayers play by the same rules. 

When fraud and illicit activity go unchecked, compliant taxpayers can bear the burden through higher enforcement costs or lost public revenue. Encouraging whistleblowers can:

• Deter abusive or fraudulent schemes 
• Promote fairness in the tax system 
• Help identify complex financial misconduct earlier 

For compliant taxpayers, that translates into a more level playing field.

Why you should pay attention

Tax professionals are often the first line of defense when it comes to identifying questionable activity. This proposal raises the stakes in several ways. 

To start, clients may become more aware of whistleblower incentives. Employees, business partners or even competitors could report suspected violations. That increases the importance of proper documentation and compliance.

In addition, practitioners must remain diligent. Situations involving foreign accounts, complex entity structures or unusual transactions may carry greater risk under enhanced enforcement. 

There may also be ethical considerations. While tax professionals generally can’t use client information freely for whistleblower purposes, they must understand the rules and advise clients accordingly. 

Finally, the existence of a structured reward system may lead to more investigations. That means more scrutiny on filings and financial reporting tied to anti-money laundering and sanctions compliance.

What to watch next

The NPRM is not yet final. FinCEN will review public comments before issuing final regulations. However, the direction is clear. The agency intends to fully implement a robust whistleblower program. Tax professionals should monitor updates and begin preparing for increased enforcement activity. Understanding how this program works will be key when advising clients in industries with higher exposure to financial reporting risks.

As always, following established guidance and maintaining strong compliance practices remain the best defense.
