How Bitcoin is taxed in the US

The IRS treats Bitcoin as property, not currency. That single classification drives almost every tax rule that follows. Every time you dispose of Bitcoin, you potentially create a taxable event. Sales are obviously taxable. Spending Bitcoin on something is technically a disposition. Gifting Bitcoin above certain limits has gift tax implications. Even using Bitcoin to buy another asset is a taxable event.

The flip side is that holding Bitcoin creates no tax liability at all. The value can swing wildly and you owe nothing until you dispose of it. Tax happens at the moment of disposition, not the moment of appreciation.

When you do dispose, you owe tax on the gain (or claim a loss) based on the difference between what you sold it for and what you paid for it, called your cost basis. The longer you’ve held, the better the tax treatment.

Holding period determines the tax rate

If you hold Bitcoin for more than a year before selling, your gain qualifies for long-term capital gains rates. These are 0%, 15%, or 20% depending on your total taxable income. For most people, this is meaningfully lower than ordinary income tax rates, which can run from 10% to 37% depending on bracket.

If you sell within a year, the gain is taxed as short-term capital gains, which uses ordinary income rates. The difference between short and long-term treatment is often the single biggest lever in Bitcoin tax planning. Holding a few extra weeks to cross the one-year mark can change your effective tax rate by 10 to 17 percentage points.

Cost basis is the number that matters

Your cost basis is what you paid for the Bitcoin originally, including any fees. When you sell, your gain is the sale price minus the basis. When you have multiple purchases over time, you need a method to decide which lots you’re selling.

The default method most platforms use is FIFO (first in, first out). You can also use specific identification, which lets you choose which lots to sell, often picking the highest-basis lots first to minimize gains. Specific identification almost always produces a better tax outcome but requires better record-keeping.

If your Bitcoin sits across multiple wallets and exchanges over years, basis tracking gets complex. Most readers eventually use crypto tax software (Koinly, CoinTracker, TokenTax) to consolidate transaction history and apply the chosen basis method consistently.

The wash-sale rule doesn’t apply to Bitcoin

For stocks, the wash-sale rule disallows claiming a loss if you buy the same security within 30 days. For Bitcoin, there’s no wash-sale rule. You can sell Bitcoin at a loss, claim the loss against other gains or up to $3,000 of ordinary income, and buy back the same amount of Bitcoin immediately.

This creates a planning opportunity that doesn’t exist with stocks. During years when Bitcoin is down significantly, holders can realize losses for tax purposes while maintaining their position. Most consumer tax content misses this entirely because it treats Bitcoin like a stock.

The IRS has periodically signaled interest in closing this gap legislatively. Congress has introduced bills to extend wash-sale rules to digital assets. None have passed yet. The current rules are still favorable, but this could change in any given year.

Spending Bitcoin is technically a sale

When you spend Bitcoin on goods or services, the IRS treats it as if you sold the Bitcoin for its dollar value at the moment of the transaction, then used those dollars to buy whatever you bought. The difference between your basis and the value at the moment of spending is a taxable gain or loss.

Almost nobody actually reports this for everyday transactions. But the rule exists, and for larger Bitcoin purchases (a car, a house deposit, a major service), it matters. Lightning Network transactions follow the same rules.

Inheritance gets a step-up in basis

When Bitcoin is inherited, the heir’s cost basis resets to the Bitcoin’s market value at the time of the original owner’s death. This is called a step-up in basis. All the gain that accumulated during the original owner’s lifetime disappears for tax purposes.

For Bitcoin specifically, where holders may have basis in the tens of dollars per coin from a decade ago, the step-up can be enormous. This is the single largest tax-planning advantage of holding Bitcoin until death rather than selling during your lifetime. It’s also why Bitcoin inheritance planning is a meaningful topic, not just a paperwork one.

Gifting is subject to annual limits

You can gift up to $19,000 worth of Bitcoin per recipient per year (2025 figure, indexed for inflation) without filing a gift tax return. Above that, you file Form 709, which counts against your lifetime estate tax exemption rather than triggering immediate tax. For most readers, gifting Bitcoin within the annual limit is a clean way to transfer wealth without immediate tax consequences.

The recipient takes on your cost basis, not a stepped-up basis. So a gift transfers the future tax liability along with the Bitcoin. This is different from inheritance, which resets basis.

State taxes vary

Federal tax rules are uniform. State tax treatment varies. Some states have no income tax (Florida, Texas, Tennessee, Washington and a few others). Some states tax capital gains as ordinary income. A few states have specific cryptocurrency provisions. Your state’s treatment can add or subtract several percentage points from your effective rate.

If you live in a high-tax state and are considering a large Bitcoin sale, the state component matters as much as the federal component for the timing decision.

Mining, Lightning, and other edge cases

If you mine Bitcoin, the value at the moment of mining counts as ordinary income, and then you have basis in the mined Bitcoin equal to that value. Lightning Network channel activity follows the same property rules as on-chain Bitcoin, though most casual Lightning use is below practical reporting thresholds. If you’re a frequent trader rather than a long-term holder, the IRS may classify you as a trader rather than an investor, which changes some loss treatment rules.

These cases are outside the scope of a guide focused on long-term holders making decisions. They’re flagged here because the rules exist, but a holder in any of those situations should work with a tax professional familiar with Bitcoin specifically.

Three principles cover most planning situations for a typical long-term holder.

Time your sales across tax years

If you’re planning a large Bitcoin sale, the year you sell matters. Splitting a large sale across two tax years can keep you from jumping into higher capital gains brackets. Long-term capital gains rates step up at specific income thresholds, and splitting can keep you in the 15% bracket rather than crossing into the 20%.

The same logic applies if you have other unusually high or low income years. Selling Bitcoin in a year you have lower other income (a sabbatical, a career transition, retirement) can drop your effective rate significantly.

Harvest losses when Bitcoin is down

When Bitcoin trades meaningfully below your basis, selling and immediately rebuying realizes a loss for tax purposes without changing your underlying position. The loss offsets gains elsewhere in your portfolio or up to $3,000 of ordinary income per year, with the remainder carrying forward indefinitely.

This is the wash-sale advantage in practice. It only matters in down years, but in down years, it can be worth several thousand dollars to readers with meaningful Bitcoin positions.

Use IRA structures for tax-deferred or tax-free growth

Bitcoin held inside an IRA grows without triggering annual tax events. Traditional IRAs defer tax to retirement; Roth IRAs eliminate it entirely for qualified withdrawals. For readers planning to hold Bitcoin for decades, the tax advantage of holding it inside an IRA compounds significantly relative to taxable accounts. See our IRA Finder and the guide on Roth vs Traditional for Bitcoin for the structural options.

Tax planning around Bitcoin rewards readers who pay attention to it and punishes readers who don’t. The differences are real. Long-term versus short-term holding is often a 10 to 17 percentage point swing in effective rate. Harvesting losses in down years can save thousands. Stepped-up basis on inheritance can erase decades of unrealized gains. None of these are obscure. All of them are routinely missed by holders who treat Bitcoin tax as paperwork rather than planning.

For most readers, the practical workflow is:

• Use crypto tax software to track basis and transactions accurately across exchanges and wallets
• Hold for more than a year before selling whenever possible
• Use specific identification to optimize which lots you sell
• Realize losses in down years to offset gains in up years
• Use IRA structures for the portion of your Bitcoin you don’t plan to access for decades
• Consult a Bitcoin-specialist tax professional for sales over roughly $50,000, gifts, and any inheritance planning

The IRS has been tightening reporting requirements for crypto every year. Form 1099-DA, expanded broker reporting, and increased audit activity on digital assets are all moving in the same direction. Better records now matter more than they did even two years ago.
