How do I report an all cash buyer to fincen without killing the deal?

As of March 2026, new nationwide regulations require specific reporting for non-financed residential transfers to entities like LLCs or trusts. You do not need to "report" the buyer personally; this is a mandatory filing performed by the closing agent, title company, or attorney as part of their standard 2026 compliance. It does not "kill the deal" because it is a non-public, back-end regulatory requirement similar to a tax filing, and it is now a routine part of the settlement process for nearly all all-cash entity purchases.

You don’t “report the buyer” yourself—under the new Financial Crimes Enforcement Network rule effective March 1, 2026, the title/escrow or closing agent is the one legally required to file the report, not you as the seller . The rule specifically targets all-cash purchases by LLCs or trusts and requires disclosure of the people behind the entity, so what your buyer is being asked for is standard compliance, not optional . Deals can fall apart if a buyer refuses to provide that info, but that’s because the closing agent can’t legally complete the transaction without filing, not because you’re “reporting” them—so the clean way to handle it is to position it as a federal requirement outside your control rather than a discretionary step.

Most legitimate business owners understand compliance requests, so this alone should not kill the deal. That said, I believe this FinCEN rule is currently on hold, so for this transaction the bigger question is whether the title company is asking for it because of an actual requirement or just its own policy. If the buyer gets unusually evasive about basic ownership information, that would concern me more than the request itself.
