Under U.S. federal law, cryptocurrency is property, not money. The IRS treats digital assets as property for tax purposes, and no cryptocurrency has legal tender status in the United States. That single classification is the reason a coffee bought with Bitcoin triggers a capital gains calculation, a creditor can refuse to accept Ether, and a failed crypto exchange leaves customers with none of the protections a failed bank would. Whether cryptocurrency is money or property matters because almost every practical question about holding, spending, or inheriting it flows from the answer.
Why Cryptocurrency Isn’t Legal Tender
Federal law defines legal tender as United States coins and currency, including Federal Reserve notes, that creditors must accept for debts, public charges, taxes, and dues.1Office of the Law Revision Counsel. 31 USC 5103 – Legal Tender No cryptocurrency meets that definition. If someone owes you money, you cannot force them to take Bitcoin, and if you owe someone, they cannot force you to pay in tokens. Two parties are free to agree by private contract to settle in crypto, but that is a voluntary arrangement, not a statutory right.
The dollar carries a permanent floor of demand because the federal government requires it for tax payments. Digital assets have no equivalent backstop. You cannot pay federal taxes in Bitcoin, satisfy a court judgment with Ether, or compel a merchant to accept any token as final payment for a debt.
The IRS did revise its 2014 guidance in 2023 to acknowledge that certain foreign jurisdictions have designated Bitcoin as legal tender within their borders.2Internal Revenue Service. Notice 2023-34 That has no effect on U.S. law. Inside the United States, crypto remains outside the legal tender framework entirely.
What “Property” Means for Your Taxes
The IRS classifies all digital assets as property for federal tax purposes.3Internal Revenue Service. Notice 2014-21 That single choice cascades into everything else. Every time you use cryptocurrency to buy something, you have technically sold property. If the value went up since you acquired the tokens, you owe capital gains tax on the difference. If it went down, you can claim a loss. Buying a cup of coffee triggers the same calculation as selling a share of stock.
How much you owe depends on how long you held the asset and your taxable income. Gains on crypto held one year or less are taxed at your ordinary income rate. Gains on crypto held more than a year qualify for long-term capital gains rates, which top out at 20%.4Internal Revenue Service. Topic No. 409, Capital Gains and Losses
For tax year 2026, the long-term brackets are:5Internal Revenue Service. Rev. Proc. 2025-32
- 0% on taxable income up to $49,450 (single), $98,900 (married filing jointly), or $66,200 (head of household).
- 15% on income above those thresholds up to $545,500 (single), $613,700 (married filing jointly), or $579,600 (head of household).
- 20% on income above the 15% thresholds.

A Loophole That May Not Last
Because crypto is property rather than a stock or security, the wash sale rule in Section 1091 does not currently apply to it. Sell Bitcoin at a loss on Monday, buy it back on Tuesday, and you can still claim the loss on your return. If you tried that with a stock, the loss would be disallowed. Congress has proposed extending wash sale treatment to digital assets more than once, and the White House has formally recommended the change, but no legislation has passed. Don’t build a long-term strategy around this gap staying open.
The Consumer Protection Gap
The property classification also explains why crypto sits outside the safety net that surrounds bank deposits. If your bank fails, FDIC insurance covers up to $250,000 per depositor, per insured bank.8FDIC. Deposit Insurance At A Glance If your crypto exchange fails, no equivalent protection exists. The FDIC has stated plainly that deposit insurance does not apply to crypto assets and does not protect against the insolvency of crypto custodians, exchanges, brokers, or wallet providers.9FDIC. What the Public Needs to Know About FDIC Deposit Insurance and Crypto Companies
Bank accounts also benefit from Regulation E, which caps consumer liability for unauthorized electronic transfers and requires the financial institution to investigate errors within 10 business days and provisionally credit the account while the investigation runs.10Consumer Financial Protection Bureau. Regulation E Section 1005.11 – Procedures for Resolving Errors Crypto transactions generally fall outside those rules. Send tokens to the wrong address, or lose them to a hacker, and the blockchain records the transfer permanently. There is no chargeback, no dispute process, and no regulator that can require the exchange to make you whole.
Some exchanges maintain internal insurance funds or added security measures, but those are contractual promises rather than federally mandated protections. When a major exchange has gone bankrupt, customers have found themselves standing in line as unsecured creditors.
Stablecoins: A Partial Exception
Stablecoins try to solve crypto’s price volatility by pegging each token to a dollar of reserves. Congress passed the GENIUS Act (Guiding and Establishing National Innovation for U.S. Stablecoins Act) in July 2025, creating the first federal framework specifically for these tokens.11Federal Register. GENIUS Act Implementation The law makes it illegal for anyone other than a permitted payment stablecoin issuer to issue a stablecoin in the United States, and beginning in July 2028, digital asset service providers generally cannot offer stablecoins to U.S. customers unless they come from a permitted issuer.
The reserve rules are strict. Issuers must back every outstanding stablecoin on at least a one-to-one basis with safe, liquid assets such as U.S. Treasury bills maturing within 93 days, cash deposits at insured banks, or holdings at the Federal Reserve.12Federal Register. Implementing the GENIUS Act for Stablecoin Issuance Reserves must be segregated from the issuer’s own assets, and the composition must be published monthly. Issuers cannot pay interest or yield on stablecoins, and they cannot market them as legal tender or as government-backed.
That last point is worth sitting with. Even a fully regulated, dollar-backed stablecoin is not money in the legal tender sense. It is still a private instrument, and it still does not carry the full faith and credit of the United States.
Using Crypto to Pay for Things Anyway
None of this stops people from spending crypto. Most crypto purchases run through third-party payment processors that convert digital assets to dollars at the current market rate. The merchant receives the exact dollar amount, avoiding volatility risk, and you pay the equivalent value in tokens plus a processing fee.
Adoption is uneven. Some major online retailers accept crypto payments; physical stores rarely do. From a mechanics standpoint, a debit card transaction settles in seconds for pennies, while a base-layer Bitcoin transaction can take minutes and cost anywhere from a couple of dollars to over $50 during congestion. Layer-2 protocols like the Lightning Network route transactions off the main chain and settle them almost instantly for fractions of a cent, but both sender and receiver need compatible wallets. The tooling works best for people already inside the crypto ecosystem.
And remember the tax angle. If you spend appreciated crypto to buy something, you have realized a capital gain and owe the tax on it, even if the purchase felt like paying with cash.
What Happens When You Die Holding Crypto
The property classification produces one meaningful benefit at the end of life. Inherited digital assets receive the same step-up in basis that applies to other inherited property. The heir’s cost basis becomes the fair market value on the date of the original owner’s death, not the price the deceased originally paid.13Internal Revenue Service. Gifts and Inheritances If someone bought Bitcoin at $500 and it was worth $60,000 at death, the heir’s basis is $60,000, and selling shortly after inheritance produces little or no taxable gain.
The catch is access. Nearly every state has adopted some version of the Revised Uniform Fiduciary Access to Digital Assets Act, which gives executors and trustees legal authority over digital assets. Legal authority means nothing without the private keys. Crypto stored in a personal wallet may be permanently unreachable if no one else knows the credentials, and the tax-efficient inheritance is worthless if the heir cannot open the wallet. Anyone holding a meaningful amount of crypto should document wallet credentials, exchange accounts, and recovery phrases somewhere a trusted person or estate attorney can find them.
