Crypto in the United States — Tax, Rules and How to Buy

Buying, holding and selling crypto is legal throughout the United States. What makes the US difficult is not legality — it is that three separate layers of rules apply at once, and the tax treatment is among the least forgiving in the developed world.

Who regulates it

There is no single crypto regulator. The SEC and the CFTC both claim jurisdiction over parts of the market and have not fully settled the boundary. On top of that, money-transmission licensing is handled state by state, which is why some platforms are unavailable in particular states even when they operate nationally. New York’s BitLicense is the strictest of these regimes and the most common reason a service is blocked in one state but not the rest.

The practical consequence: check availability for your own state, not just the country.

How it is taxed

The IRS treats digital assets as property, not currency. That single decision drives everything else.

• Every disposal is a taxable event. Selling for dollars, swapping one token for another, and spending crypto on goods are all disposals. Crypto-to-crypto trades catch people out constantly — there is no dollar in sight, but a gain is realised.
• Holding period sets the rate. Held a year or less, a gain is taxed at ordinary income rates. Held longer than a year, it falls under long-term capital gains rates, which are substantially lower.
• No small-transaction exemption. Unlike several countries on this list, there is no threshold below which a gain is ignored. A two-dollar profit is technically reportable.
• Staking rewards are income when you receive them, valued at that moment, and then have their own cost basis for a later disposal.
• Loss harvesting is unusually flexible. The wash-sale rule that stops investors from selling a stock at a loss and immediately rebuying it has not been extended to crypto. Congress has repeatedly proposed closing this; assume it will not last forever.

Exchanges now issue broker reporting forms for digital assets, which means the IRS increasingly receives its own copy of your activity. Reporting a different number to theirs is what triggers letters.

Where you can actually buy

US users have fewer venues than most of the world, and the gap is not about fees — several of the cheapest global exchanges simply do not serve US retail customers. Coinbase, Kraken, Gemini and Crypto.com all operate in the US with real dollar rails: ACH transfer, wire, and debit card. Binance’s main international platform, OKX, Bybit, KuCoin, MEXC and Gate are not open to US retail users, which removes most of the low-fee options in our exchange comparison from consideration.

The realistic choice for most Americans is therefore between Coinbase and Kraken, and the fee difference between their beginner and advanced interfaces is far larger than the difference between the two companies.

The mistakes that cost Americans money

• Using the simple buy button. On both major US exchanges, the beginner flow costs several times what the advanced interface charges for an identical trade. This is the single most expensive habit in US retail crypto.
• Forgetting that swaps are taxable. Rotating between tokens during a bull market can generate a large tax bill on gains you never converted to dollars — and if the market falls before you file, you may owe tax on money you no longer have.
• Ignoring state rules. State income tax applies on top of federal, and availability of platforms and products differs by state.
