If you’ve sold cryptocurrency at a profit, the IRS wants its cut—and how much you pay depends almost entirely on how long you held that asset before selling. Holding for just a few extra months can mean the difference between paying 37% in taxes and paying nothing at all. The tax treatment of crypto capital gains isn’t complicated, but it does matter, and misunderstanding it has cost investors thousands.

This guide covers how short-term and long-term capital gains taxes work on cryptocurrency, what the 2024 and 2025 tax rates actually look like, and how to structure your holdings to minimize what you owe.

What Are Short-Term Capital Gains on Crypto?

Short-term capital gains apply when you sell cryptocurrency you’ve held for less than one year. The IRS treats these gains as ordinary income, which means they get taxed at your regular income tax bracket.

For the 2024 tax year, ordinary income tax brackets range from 10% to 37% depending on your filing status and total income. For 2025, these brackets adjust slightly for inflation.

Here’s where it gets expensive: if you’re in the 32% bracket and you buy $10,000 in Bitcoin, watch it grow to $15,000, and sell after eight months, you owe taxes on that $5,000 profit at 32%—that’s $1,600 gone to the IRS. There’s no loophole here. The IRS views this as your paycheck, just from a different source.

The holding period starts the day after you acquire the cryptocurrency and ends on the day you sell it. If you buy crypto on January 15 and sell it on January 14 of the following year, that’s still short-term. You need to hold through the full 366th day for it to qualify as long-term.

What Are Long-Term Capital Gains on Crypto?

Long-term capital gains apply when you sell cryptocurrency you’ve held for more than one year. These gains are taxed at preferential capital gains rates rather than ordinary income rates.

For 2024 and 2025, long-term capital gains tax rates are:

Using the same example: if you bought $10,000 in Bitcoin, it grew to $15,000, and you sold after holding for 13 months, your $5,000 gain falls into the 15% bracket if you’re a single filer making under $518,900. That’s $750 in taxes instead of $1,600.

There’s also a 3.8% Net Investment Income Tax (NIIT) that applies to investment gains for individuals with modified adjusted gross income above $200,000 ($250,000 for married couples). This stacks on top of your capital gains rate, so some high earners actually pay 18.8% or 23.8% on long-term gains.

How to Calculate Your Crypto Capital Gains

Calculating your gain or loss follows a straightforward formula:

Proceeds from Sale – Cost Basis = Capital Gain (or Loss)

Your cost basis includes what you paid for the cryptocurrency plus any transaction fees. If you bought the same crypto at different times at different prices, you can use several accounting methods:

Specific identification lets you choose which specific units you’re selling—useful if you want to sell the ones with the highest cost basis to minimize gains.

FIFO (First In, First Out) assumes you sell your oldest holdings first. This is the default if you don’t specify otherwise and can result in higher taxes if prices have risen significantly since you first bought.

HIFO (Highest In, First Out) sells your most expensive holdings first, minimizing gains. This requires good record-keeping and typically only works if your exchange supports it.

Here’s a practical example: Say you bought 0.5 Bitcoin at $30,000 in January 2023, another 0.5 at $50,000 in July 2023, and 0.5 at $70,000 in January 2024. In March 2024, you sell 1 Bitcoin for $75,000. Under FIFO, your cost basis is $40,000 (the first two purchases), so your gain is $35,000 and it’s short-term. Under HIFO, you could sell the $70,000 and $50,000 purchases, giving you a cost basis of $60,000 and a gain of $15,000—still short-term, but with a smaller tax bill.

The Wash Sale Rule and Crypto: A Tricky Edge Case

Here’s something most articles on this topic get wrong: the wash sale rule technically applies to stocks and securities, not to cryptocurrency. As of early 2025, the IRS has not explicitly extended the wash sale rule to crypto transactions.

However, don’t take this as an invitation to aggressively game the system. The rule could change, and the IRS has shown increasing interest in cryptocurrency compliance. If you sell at a loss and repurchase substantially identical crypto within 30 days, you may still face scrutiny even if the current rules don’t explicitly apply the wash sale penalty.

The safest approach? Don’t sell crypto specifically to claim a loss if you plan to buy it back immediately. That’s exactly what the wash sale rule was designed to prevent, and regulators have signaled they want to close this gap.

Can You Offset Crypto Gains With Losses?

Yes, and this is one of the most useful strategies available to crypto investors. You can use capital losses to offset capital gains, and if your losses exceed your gains, you can offset up to $3,000 of ordinary income per year, with the remainder carrying forward to future years.

This is called tax-loss harvesting, and it works like this: if you have $10,000 in gains from one crypto you sold at a profit but $7,000 in losses from another trade, you only pay taxes on $3,000 of net gain. If you have $12,000 in losses and $5,000 in gains, you have $7,000 in net losses, $3,000 of which offsets ordinary income and $4,000 carries forward.

The key caveat is that you can’t simply sell and repurchase the same asset immediately. However, you can sell a losing position and buy a different cryptocurrency that serves a similar purpose in your portfolio. Just make sure the assets aren’t “substantially identical” in the IRS’s view.

Holding Period Calculation: Why the One-Year Mark Matters

The distinction between short-term and long-term comes down to a single day. Under Internal Revenue Code Section 1222, property held for one year or less qualifies for short-term treatment, while property held for more than one year qualifies for long-term.

For crypto specifically, this creates some planning opportunities:

If you bought crypto on March 15, 2024, it becomes long-term eligible on March 16, 2025—not March 15. You need to hold through the full 366th day.

For gifted or inherited crypto, the holding period carries over from the original owner. If your grandfather bought Bitcoin in 2012 and gave it to you in 2024, your holding period dates back to 2012, meaning it’s automatically long-term.

When you receive crypto from a hard fork or airdrop, the holding period starts fresh on the date you receive the new coins. This is a common oversight—if you received new tokens from a chain split and sold them within a year, they’ll be taxed as short-term gains even if the original Bitcoin was held for years.

Frequently Asked Questions

How long do I need to hold crypto to avoid short-term capital gains taxes?

You must hold cryptocurrency for more than one year (366+ days) to qualify for long-term capital gains rates. If you sell at 365 days or less, it will be taxed as ordinary income.

Do I pay taxes on crypto if I only exchanged it for another cryptocurrency?

Yes. In the IRS’s view, selling one cryptocurrency for another is a taxable event. You’re disposing of an asset (the first crypto) and acquiring a new one (the second crypto). The gain or loss is measured in dollars—even though you never touched fiat.

What happens if I lost money on crypto? Can I deduct those losses?

You can deduct capital losses against capital gains, and up to $3,000 per year against ordinary income. This makes tax-loss harvesting a legitimate strategy, though you should be careful about the wash sale rule and “substantially identical” repurchases.

What if I received crypto as a gift or through airdrop?

Gifts use the giver’s cost basis. Airdrops and hard forks are treated as ordinary income at their fair market value on the day you receive them, then your holding period starts from that receipt date.

Planning Ahead: What Smart Crypto Investors Do

The most effective tax strategy for cryptocurrency is straightforward: hold for more than a year whenever possible. If you believe in a project long-term, the tax savings alone can justify not trading frequently.

For assets you do need to sell within a year, consider bunching multiple losses together to offset gains, or time your short-term sales to years when your ordinary income is lower.

Most importantly, keep meticulous records. Every transaction—every swap, every purchase, every airdrop—needs documentation. The moment the IRS comes asking questions, you’ll want a clear cost basis trail for every single unit of crypto you’ve ever held.
