Bitcoin in Montana: what to know
Montana has no statewide crypto ATM limits; operators set their own. Crypto gains are taxed as income, with net long-term capital gains taxed at reduced rates since 2024. The state does not accept crypto for tax payments.
Bitcoin has one price in US dollars across the country: the price on this page is the same as on the bitcoin price in the United States page, where federal tax rules are covered in full. What differs in Montana is state law and tax, explained below.
Crypto ATMs in Montana
Montana has no kiosk-specific law. Scammers often tell victims to pay through crypto ATMs: no government agency, bank or utility asks for payment in bitcoin.
Buying bitcoin in Montana
Montana has no money transmitter licensing law, so exchanges and kiosk operators need no state license; federal FinCEN registration still applies. Buying bitcoin carries no sales tax; you pay the exchange's spread and fees.
Tax on bitcoin in Montana
Crypto gains are taxed as income, with net long-term capital gains taxed at reduced rates since 2024. The state does not accept crypto for tax payments. Federally, the IRS treats bitcoin as property: selling, trading or spending it is a taxable event, with short-term gains (held a year or less) taxed as ordinary income and long-term gains at 0%, 15% or 20%; bitcoin received as pay or from mining is income. Exchanges and other custodial brokers report sales on Form 1099-DA: gross proceeds for sales from 1 January 2025, and cost basis for many sales from 1 January 2026. Every Form 1040 asks whether you received or disposed of a digital asset.
State bitcoin reserve
A bill allowing investment in digital assets and precious metals (HB 429) failed on the House floor in 2025.
Other crypto laws in Montana
SB 178 (2023) protects crypto mining and bars taxes imposed just because a payment is made in digital assets. SB 265 (2025, effective October 1, 2025) protects self-custody, running nodes and staking, and bars a CBDC.
