Short-term vs long-term crypto gains

By the ChainTax Editorial Team · Updated June 2026 · Researched from authoritative sources. General information, not professional advice.

The single number that does the most to set your crypto tax bill is not how much you made — it is how long you held before you sold. The Internal Revenue Service (IRS) treats cryptocurrency as property, so when you dispose of it you realize a capital gain or loss, and that gain is sorted into one of two buckets based on your holding period. The two buckets are taxed very differently.

The one-year line, and exactly how it is measured

The dividing line is one year. The IRS rule for measuring a holding period is precise: you begin counting on the day after you acquired the asset, and you count through the day you dispose of it. So if you bought on January 1, your holding period starts January 2. To qualify for long-term treatment you must hold for more than one year — holding for exactly one year or less leaves you in the short-term bucket.

• Held one year or less → short-term capital gain, taxed at your ordinary income tax rates.
• Held more than one year → long-term capital gain, taxed at the preferential 0%, 15%, or 20% rates.

That one extra day can move a gain from ordinary rates (which reach into the high 30s percent for top earners) down to a maximum of 20%. The IRS describes the holding-period rule and the two rate structures in its capital gains guidance, including the Topic on capital gains and losses; review it directly before you rely on any figure.

Short-term: taxed like a paycheck

Short-term crypto gains are stacked on top of your wages, self-employment income, and other ordinary income, then taxed at the same graduated brackets. There is no special discount. If a quick flip pushes you into a higher ordinary bracket, the gain is taxed at that higher marginal rate. For most active traders, short-term treatment is simply the worst-case outcome for any given dollar of profit.

Long-term: the preferential 0/15/20 brackets

Long-term gains use their own rate schedule of 0%, 15%, or 20%, and which rate applies depends on your total taxable income. Lower-income taxpayers can land in the 0% band and owe nothing on a qualifying long-term gain; most middle-income taxpayers fall in the 15% band; only higher-income taxpayers reach 20%. The income thresholds that separate these bands are adjusted every year for inflation. Do not memorize a dollar figure from any article, including this one — verify the current-year thresholds with the IRS, because they change annually.

A worked example: the same gain, taxed both ways

Suppose you bought 1 ETH and later sold it for a $10,000 profit. Assume you sit in a 24% ordinary bracket and the 15% long-term band. Look at what the holding period alone does:

Identical asset, identical $10,000 gain — but waiting roughly two more months saves $900, a 37.5% reduction in tax on that gain. Scale that across a portfolio and the holding period becomes the single biggest controllable lever on a crypto tax bill. You cannot control the market, but you can often control the calendar. (Rates above are illustrative; your actual brackets may differ.)

The extra 3.8% for higher earners (NIIT)

If your income is above certain thresholds, the IRS Net Investment Income Tax (NIIT) adds 3.8% on top of capital gains and other investment income. It applies to both short-term and long-term gains, so a high earner in the 20% long-term band can effectively face 23.8% federally. The NIIT thresholds are set in statute rather than indexed yearly, but you should still confirm whether you are over the line for your filing status with the IRS.

Crypto-to-crypto trades reset the clock

A point that surprises many investors: swapping one coin for another is a taxable disposal, not a tax-free rollover. When you trade BTC for ETH, you dispose of the BTC (realizing gain or loss) and your holding period on the new ETH starts the next day from zero. Every swap resets the clock. Frequent rotation between tokens can keep you permanently in short-term territory even if you have been "in crypto" for years.

Choosing which lots to sell: specific ID vs FIFO

If you bought the same coin at different times, each purchase is a separate "lot" with its own cost basis and holding period. When you sell only part of your position, the lot you are deemed to sell changes the result. The IRS default is FIFO (first-in, first-out) — the oldest coins go first. But you may instead use specific identification if you can adequately identify the exact units sold, with records of acquisition date, basis, and the units disposed.

• FIFO sells your oldest lots first — often long-term, but possibly your lowest-basis (largest-gain) coins.
• Specific identification lets you deliberately pick lots held more than a year to favor long-term rates, or pick high-basis lots to shrink the gain.

Specific ID is powerful but documentation-heavy. You report each disposal on Form 8949 and total it on Schedule D, so your records must support whichever lots you claim to have sold.

Planning levers you actually control

• Wait past the one-year mark. If a position is near its anniversary and you do not urgently need the cash, crossing into long-term can cut the rate on that gain substantially.
• Harvest losses against gains. Selling losers can offset winners dollar for dollar. See our companion guide on loss harvesting below.
• Time disposals in low-income years. A gap year, sabbatical, or early-retirement year may put you in the 0% or 15% long-term band, so realizing gains then can be remarkably cheap.
• Use specific ID to steer sales toward long-term, high-basis lots.

Capital-loss rules: offsets and carryforwards

Losses are not wasted. Capital losses first offset capital gains of the same type, then across types. If your total capital losses exceed your total capital gains, you may deduct up to $3,000 of the net loss against ordinary income each year ($1,500 if married filing separately). Any remaining loss carries forward to future years indefinitely, where it can offset future gains or another $3,000 of ordinary income annually. Losses are reported through Form 8949 and Schedule D alongside your gains. Confirm the current dollar limit with the IRS, as Congress can adjust it.
