Cryptocurrency Laws in the United States: Complete 2026 Guide

Is Cryptocurrency Legal in the United States?

Yes. Cryptocurrency is legal across all 50 US states. No federal law prohibits ownership, trading, mining, or transfer of digital assets between individuals. What the US does have — and what makes it the world\'s most actively-enforced jurisdiction for crypto — is overlapping regulation from five federal agencies and 50 state regulators.

At the federal level, the Internal Revenue Service (IRS) has treated cryptocurrency as property for tax purposes since Notice 2014-21. The Securities and Exchange Commission (SEC) regulates tokens that meet the Howey test for an investment contract. The Commodity Futures Trading Commission (CFTC) has classified Bitcoin and Ether as commodities since 2015. The Financial Crimes Enforcement Network (FinCEN) requires exchanges and other "money transmitters" to register as Money Services Businesses (MSBs) under the Bank Secrecy Act. The Office of the Comptroller of the Currency (OCC) governs how chartered banks may custody crypto.

The 2025 outlook brings further clarity: the Financial Innovation and Technology for the 21st Century Act (FIT21), passed by the House in May 2024, would formally split market jurisdiction between the SEC and CFTC. The bipartisan Lummis-Gillibrand Responsible Financial Innovation Act provides a competing framework. Either way, US crypto users in 2025 operate under a workable — if complex — set of rules.

What\'s not allowed: privacy-coin focused mixers (after the OFAC sanctions on Tornado Cash in August 2022), unregistered securities offerings, and money transmission without state licences. Otherwise, US persons may buy, sell, hold, and use cryptocurrency freely.

Crypto Exchanges Available in the United States

Every US-serving exchange must register as an MSB with FinCEN and obtain money transmitter licences in each state where it offers services. New York additionally requires a BitLicense. Below is the status of the major global platforms for US residents as of May 2026.

For decentralised exchanges (Uniswap, Curve, Aave) the legal status is the user\'s own — US users may interact with on-chain protocols, but the front-end interfaces sometimes geo-block specific states. The SEC issued a Wells notice to Uniswap Labs in April 2024 but withdrew enforcement in February 2025.

US Crypto Regulatory Timeline

KYC and AML Requirements in the United States

Every US-registered crypto exchange is a Money Services Business under the Bank Secrecy Act and must implement an Anti-Money Laundering programme. In practice, this means platforms collect government-issued ID, proof of address, Social Security Number, and increasingly source-of-funds documentation for larger transactions.

The threshold for required reporting is low. Currency Transaction Reports (CTRs) are filed for cash transactions over $10,000. Suspicious Activity Reports (SARs) are filed for any pattern the exchange deems suspicious — often as low as a few thousand dollars in mixed or rapidly-cycled transactions. From 2025, exchanges are also required to report customer transactions on Form 1099-DA, which the IRS will use to cross-check taxpayer returns.

The Travel Rule (FinCEN\'s rule mirroring FATF Recommendation 16) requires US Virtual Asset Service Providers to transmit originator and beneficiary information for crypto transfers over $3,000. Practically, this means exchanges share KYC data with each other when you withdraw to another platform.

DeFi and NFT Regulations in the US

Decentralised Finance occupies a contested legal space. The SEC has argued in multiple actions that DeFi front-ends and governance-token projects constitute unregistered securities exchanges. The Uniswap Wells notice (April 2024, withdrawn February 2025) was the highest-profile test. As of 2026, no general DeFi statute exists — users interact with protocols at their own legal risk, and front-end operators face significant uncertainty.

Non-Fungible Tokens are not categorically securities. The SEC\'s 2023 action against Impact Theory and OpenSea\'s 2024 Wells notice indicated that NFTs can be securities when sold with profit promises. Most personal NFT trading remains a tax matter (the IRS treats NFT sales as collectibles, taxed up to 28%) rather than a securities-law matter.

State-Level Rules — The New York BitLicense and Others

Beyond federal rules, every US state has its own money transmitter regime. The most restrictive is New York\'s BitLicense, administered by the Department of Financial Services (NYDFS), introduced in 2015. Only about 30 firms hold it.

Other notable state regimes include Texas\'s Money Services Act (with crypto-friendly amendments in 2021 and 2023), Wyoming\'s Special Purpose Depository Institution charters (designed for crypto banks like Kraken Financial), Louisiana\'s Virtual Currency Businesses Act, and California\'s Digital Financial Assets Law (effective July 2025). Some states (Wyoming, Texas, Florida) actively court crypto businesses; others (New York, Hawaii historically) impose higher friction.

State-level stablecoin laws are accelerating. New York permits regulated stablecoins through NYDFS-chartered trust companies (Paxos, Gemini, Circle\'s NYDFS BitLicense). Texas\'s 2023 law explicitly addresses commodity-backed stablecoins. A federal stablecoin framework remains a 2025 legislative priority.

US Crypto Taxes — Summary

The IRS treats cryptocurrency as property. Every disposal — selling for fiat, swapping crypto for crypto, paying for goods, gifting above the annual exclusion — is a taxable event. Short-term gains (assets held ≤12 months) are taxed at ordinary income rates from 10% to 37%. Long-term gains (assets held over 12 months) are taxed at 0%, 15%, or 20% depending on income. Mining and staking rewards are taxed as ordinary income at fair market value at receipt.

From 2025, US crypto brokers must report customer transactions on Form 1099-DA. The Form 1040 contains a mandatory question about digital asset activity. Failure to report can trigger penalties from accuracy-related fines (20% of underpayment) to civil fraud (75%) and, in willful cases, criminal prosecution.
