Understanding how cryptocurrency is taxed is essential for any investor navigating the digital asset space. When you sell or dispose of crypto, that transaction may trigger a capital gains tax liability. The key to minimizing your tax burden lies in knowing the difference between short-term and long-term capital gains—and how each is treated by the IRS.
What Are Capital Gains on Cryptocurrency?
A capital gain occurs when you sell an asset for more than its purchase price. This applies not only to traditional investments like stocks and real estate but also to cryptocurrencies such as Bitcoin, Ethereum, and Dogecoin. The IRS classifies crypto as a capital asset, meaning every profitable trade, sale, or use of crypto for goods and services could be a taxable event.

For example:
- You buy 1 ETH for $1,500 and later sell it for $1,700 → $200 capital gain (taxable).
- If you paid a $20 transaction fee, your taxable gain drops to $180.
- Conversely, selling that ETH for $1,500 after buying it at $4,500 results in a capital loss of $3,000, which can help reduce your overall tax bill.
These rules ensure that whether you're day trading or holding long-term, tax implications follow every move.
Common Cryptocurrency Taxable Events
Not all crypto activity involves direct cash sales, but many actions still count as taxable events. Be aware of the following:
- Selling cryptocurrency for fiat currency (e.g., USD)
- Trading one cryptocurrency for another (e.g., BTC for SOL)
- Using crypto to purchase goods or services
- Receiving crypto as payment for work or through mining/staking rewards
Each of these scenarios requires accurate recordkeeping and potentially triggers a capital gains or losses calculation. Even swapping tokens on a decentralized exchange counts—there’s no exemption simply because no fiat changed hands.
Short-Term vs. Long-Term Capital Gains: The Key Difference
The IRS separates capital gains into two categories based on holding period:
Short-Term Capital Gains (Held ≤ 1 Year)
If you hold your cryptocurrency for one year or less before selling, any profit is considered a short-term capital gain. These gains are taxed at your ordinary income tax rate, which ranges from 10% to 37%, depending on your income level and filing status.
This means if you’re in a high-income bracket, short-term trading profits could be taxed nearly as much as your salary.
Long-Term Capital Gains (Held > 1 Year)
Holding crypto for more than 365 days qualifies the gain as long-term, which benefits from significantly lower tax rates: 0%, 15%, or 20%, based on your taxable income and filing status.
Here’s a simplified breakdown of 2025 long-term capital gains brackets:
Single filers:
- 0% on gains up to $44,625
- 15% on gains from $44,626 to $502,300
- 20% on gains above $502,300
Married filing jointly:
- 0% up to $89,250
- 15% up to $563,750
- 20% above $563,750
Note: Rates referenced are projected for 2025 and align with current IRS indexing trends.

Real-World Example: How Holding Period Affects Taxes
Meet Sarah, a single filer earning $55,000 annually. She bought 1 BTC for $30,000 and sold it a year later for $35,000—realizing a $5,000 gain.
- If held less than a year:
Taxed at her ordinary income rate of 22% → $1,100 in taxes. - If held over a year:
Taxed at the long-term rate of 15% → $750 in taxes.
By simply waiting an extra few months, Sarah saves $350—a clear incentive to adopt a longer-term investment mindset.
Offsetting Gains with Capital Losses
You don’t always profit from crypto trades. When you sell at a loss, that capital loss can offset gains elsewhere in your portfolio.
Key rules:
- Use capital losses first to offset gains of the same type (short-term vs. short-term).
- Any net capital loss can offset up to $3,000 of ordinary income annually.
- Excess losses carry forward indefinitely to future tax years.
This strategy—called tax-loss harvesting—is widely used by savvy investors to reduce their annual tax liability without exiting their market positions entirely.
Choosing the Right Accounting Method: FIFO, LIFO, HIFO
If you’ve made multiple purchases of the same cryptocurrency at different prices, your choice of accounting method affects your taxable gain.
Common methods include:
- FIFO (First In, First Out): Assumes the oldest coins are sold first. Most commonly used and IRS-default unless specified.
- LIFO (Last In, First Out): Assumes newest purchases are sold first. Can be beneficial in rising markets if early buys were low-cost.
- HIFO (Highest In, First Out): Sells the highest-cost basis units first—ideal for minimizing taxes during high-gain periods.
Example:
You bought ETH at $1,000, then $2,500, then $3,000. Selling one unit when ETH is worth $3,200:
- FIFO → Gain = $2,200 ($3,200 – $1,000)
- HIFO → Gain = $200 ($3,200 – $3,000)
Choosing HIFO here reduces your taxable gain by $2,000.
Always document your chosen method consistently across tax filings.
Strategic Ways to Minimize Crypto Taxes
Beyond timing and accounting methods, consider these proven strategies:
1. Hold for Over One Year
Align sales with long-term status to access lower tax brackets.
2. Harvest Tax Losses
Sell underperforming assets to offset gains and reduce taxable income.
3. Use Tax-Advantaged Accounts
Investing crypto through a Self-Directed IRA or similar vehicle can defer or eliminate capital gains taxes.
4. Donate Appreciated Crypto
Giving crypto directly to qualified charities avoids capital gains tax entirely and may qualify for a deduction.
5. Track All Transactions Meticulously
Use reliable crypto tax software to log trades, fees, and disposals accurately.

Frequently Asked Questions (FAQ)
Q: Do I owe taxes if I don’t convert crypto to cash?
A: Yes. Trading one crypto for another or using crypto to pay for goods is a taxable event—even without touching fiat currency.
Q: Are all short-term gains taxed at 37%?
A: No. Short-term gains are taxed at your ordinary income rate, which depends on your total income and filing status. Only the highest earners face the 37% bracket.
Q: Can I avoid capital gains by reinvesting profits?
A: Not under current U.S. law. Unlike like-kind exchanges in real estate (now limited), crypto transactions do not qualify for deferral through reinvestment.
Q: What happens if I lose money on crypto?
A: You can use those losses to offset other capital gains. Up to $3,000 in net losses can reduce ordinary income annually; excess carries forward.
Q: Does staking or mining income count as capital gains?
A: No—initial receipt is taxed as ordinary income based on fair market value. Future sales of staked/mined coins will trigger capital gains/losses.
Q: Is there a tax-free threshold for small crypto transactions?
A: No. All disposals—even tiny amounts—are technically reportable. However, proper recordkeeping ensures compliance without overburdening small traders.
