Is Bitcoin Self-Custody Legal in the US? What Federal Law Says

Yes. US federal money transmission rules apply to people who accept and transmit value for others, not to individuals holding their own Bitcoin. FinCEN's 2019 guidance states that a person using an unhosted wallet to buy goods or services on their own behalf is "not a money transmitter."

On October 6, 2026, FinCEN withdrew its 2020 proposal on transactions involving unhosted wallets. The CLARITY Act, passed by the House in July 2025, would write a right to self-custody into federal law, but it has not passed the Senate.

Federal guidance uses the term "unhosted wallet." FinCEN guidance FIN-2019-G001, "Application of FinCEN's Regulations to Certain Business Models Involving Convertible Virtual Currencies," draws the distinction in Section 4.2.

It describes the custodial model this way: "Wallets where user funds are controlled by third parties are called 'hosted wallets.'" It describes unhosted wallets as "software hosted on a person's computer, phone, or other device" that lets the person store and transact in convertible virtual currency without an additional third party.

FinCEN's term for Bitcoin and similar assets in this guidance is convertible virtual currency, or CVC. In plain terms, a hosted wallet is an exchange or custodian account, and an unhosted wallet is self-custody.

Businesses that move value for other people. FinCEN's regulations define a money transmitter in 31 CFR 1010.100(ff)(5)as "A person that provides money transmission services."

The same paragraph defines money transmission services as "the acceptance of currency, funds, or other value that substitutes for currency from one person and the transmission of currency, funds, or other value that substitutes for currency to another location or person by any means."

The definition turns on acting for someone else. A person who holds their own Bitcoin and spends it is not accepting value from another person to transmit it onward.

No, when acting on their own behalf. Section 4.2.1 of FIN-2019-G001 states: "In so far as the person conducting a transaction through the unhosted wallet is doing so to purchase goods or services on the user's own behalf, they are not a money transmitter."

The guidance builds on FinCEN's earlier definition of a user as "a person that obtains virtual currency to purchase goods or services" on the user's own behalf. Section 3 adds that how a person obtained the Bitcoin, for example by mining or by purchase, does not decide whether they are a user, an administrator or an exchanger.

Yes. Section 4.2.1 of the guidance treats hosted wallet providers as account-based money transmitters. They hold and move value for their customers, which is the activity the money transmitter definition covers.

Not for providing the software alone. FIN-2019-G001 addresses several tool providers:

The House-passed CLARITY Act takes a similar line. Its Section 109(a)(2) says a non-controlling developer or service provider is not treated as a money transmitter solely for "providing hardware or software to facilitate a customer's own custody or safekeeping of the customer's digital assets," according to the engrossed text.

Not when you use the Bitcoin for yourself. Section 5.3 of FIN-2019-G001 states: "To the extent that a person mines CVC and uses it solely to purchase goods or services on its own behalf, the person is not an MSB under FinCEN regulations." A miner who uses Bitcoin to engage in money transmission is subject to the obligations of a money services business.

Mining pools are addressed in Section 5.4. Distributing mined Bitcoin to pool members "does not qualify as money transmission under the BSA," because it is integral to the service the pool provides. If the pool also hosts wallets for its members, the analysis changes.

FinCEN withdrew it. On December 23, 2020, FinCEN proposed a rule at 85 FR 83840 aimed at transactions involving unhosted wallets. According to the withdrawal notice published at 91 FR 63514, the proposal would have required banks and money services businesses to "submit reports, keep records, and verify the identity of customers" for these transactions.

The proposal would have applied when a counterparty used an unhosted wallet or a wallet hosted in a jurisdiction identified by FinCEN:

The withdrawal applies as of October 6, 2026. The notice states that "FinCEN will not take any further action on this NPRM." It ties the withdrawal to the administration's effort to make digital asset rules "fit-for-purpose," following a report by the President's Working Group on Digital Asset Markets established under Executive Order 14178.

FinCEN announced the withdrawal in a press release dated October 5, 2026.

The proposal never targeted individuals directly. It would have placed duties on banks and money services businesses dealing with unhosted wallets. With the withdrawal, those duties will not be adopted under that proposal.

It set out its enforcement priorities in 2025. On April 7, 2025, the Deputy Attorney General issued a memorandum titled "Ending Regulation By Prosecution".

The memo states that "the Department will no longer target virtual currency exchanges, mixing and tumbling services and offline wallets for the acts of their end users or unwitting violations of regulations." It also states that the Department "will no longer pursue litigation or enforcement actions that have the effect of superimposing regulatory frameworks on digital assets."

The memo lists the conduct it will prioritize, including the use of digital assets "in furtherance of criminal offenses such as terrorism, narcotics and human trafficking, organized crime, hacking, and cartel and gang financing."

A memo sets the Department's enforcement priorities. It does not change the statutes or FinCEN's regulations.

It would write a self-custody right into federal law. Section 105(c) of the House-passed text of H.R. 3633, titled "Protection of Self-Custody," states that "A United States individual shall retain the right to":

The peer-to-peer right applies if the other party "is not a financial institution (as defined in section 5312 of title 31, United States Code)" and if the transactions do not involve property blocked or "otherwise prohibited by, United States sanctions."

Section 105(c)(2) limits the right. It "applies solely to personal use by individuals" and "does not apply to individuals acting in a custodial or fiduciary capacity for others." Section 105(c)(3) preserves federal enforcement authority, including under the Bank Secrecy Act and sanctions laws.

No. According to the Congressional Record, the House passed H.R. 3633 on July 17, 2025, by 294 yeas to 134 nays. On September 15, 2026, the Senate Press Gallery log records: "By a vote of 49-50, the Senate did not agree to the motion to invoke cloture on the motion to proceed to H.R.3633."

Until both chambers pass it, Section 105(c) is a proposal. The current federal position on self-custody rests on FinCEN's regulations and guidance.

No. Q38 of the IRS FAQ on virtual currency transactions states that a transfer between your own wallets is "a non-taxable event," even if an exchange or platform sends you an information return about it.

The sources above lead to a few clear points:

Yes. Federal money transmission rules cover accepting and transmitting value for others. FinCEN guidance FIN-2019-G001 states that a person using an unhosted wallet to buy goods or services on their own behalf is not a money transmitter. Custodial wallet providers, by contrast, are treated as money transmitters.

FinCEN uses the term for self-custody. In FIN-2019-G001, unhosted wallets are software on a person's computer, phone or other device that lets them store and transact without a third party. Hosted wallets are those "where user funds are controlled by third parties."

Yes. FinCEN withdrew its December 23, 2020 proposal as of October 6, 2026. It would have required reports and identity checks above $10,000 and records above $3,000 for certain unhosted wallet transactions. FinCEN "will not take any further action" on it.

Not if you use the Bitcoin for yourself. FIN-2019-G001 states that a person who mines and uses the currency "solely to purchase goods or services on its own behalf" is not an MSB. Using it for money transmission changes that.

Not for providing the software alone. Under FIN-2019-G001, a multi-signature wallet provider that only creates unhosted wallets "is not a money transmitter because it does not accept and transmit value." The guidance also says a DApp developer is not a money transmitter "for the mere act of creating the application."

Its House-passed text would. Section 105(c) of H.R. 3633 gives US individuals the right to keep a hardware or software wallet for their own lawful custody of digital assets. The bill passed the House on July 17, 2025, but the Senate has not passed it.

No. The IRS FAQ calls a transfer between your own wallets "a non-taxable event," even if a platform sends you an information return about it. A sale, exchange or payment with Bitcoin is a different matter and can produce a capital gain or loss.
