The IRS treats cryptocurrency as property, not currency. That means nearly every transaction — selling, trading, spending, and even receiving crypto — can create a taxable event. The rules are complicated, the reporting requirements are strict, and the penalties for getting it wrong are real. Here's everything you need to know about crypto taxes in 2024, 2025, and 2026.

How Are Crypto Taxes Calculated?

Cryptocurrency is taxed as property by the IRS. When you sell, trade, or spend crypto, you owe capital gains tax on the difference between what you paid (cost basis) and what it was worth at the time of the transaction. Short-term gains (held under one year) are taxed at your ordinary income rate (up to 37%), while long-term gains (held over one year) are taxed at preferential rates of 0%, 15%, or 20%.

Crypto Is Property, Not Currency

Since IRS Notice 2014-21, cryptocurrency has been classified as property for federal tax purposes. This means it follows the same rules as stocks, real estate, and other capital assets, not the rules for foreign currency. Every time you dispose of crypto (sell, trade, spend, or gift above the exclusion), you need to calculate whether you had a gain or loss.

This classification has massive implications. Swapping one cryptocurrency for another isn't like exchanging euros for dollars; it's a taxable event, just like selling stock and buying a different stock. Many crypto users have been caught off guard by this.

Taxable vs Non-Taxable Crypto Events

Short-Term vs. Long-Term Crypto Capital Gains

Just like stocks, the one-year holding period determines your tax rate. Crypto held for more than one year qualifies for long-term capital gains rates (0%, 15%, or 20%). Crypto held for one year or less is taxed as short-term capital gains at your ordinary income rate.

Active traders who buy and sell frequently are almost always paying short-term rates, which can be up to 37%. Long-term holders who bought and held for over a year benefit from the lower rates. This is a meaningful incentive to think twice before that impulsive trade. High earners may also owe the 3.8% Net Investment Income Tax (NIIT) on top of capital gains rates.

Cost Basis Methods for Cryptocurrency

Your cost basis determines how much gain or loss you realize when you dispose of crypto. If you bought Bitcoinat different times and prices, which purchase's cost basis do you use? That depends on your accounting method:

• FIFO (First In, First Out): The default method. The first coins you bought are treated as the first coins you sold. In a rising market, FIFO often produces the largest gains because your oldest (cheapest) coins are sold first.
• HIFO (Highest In, First Out): The coins with the highest cost basis are sold first, minimizing your current taxable gain. This can be advantageous for tax optimization.
• Specific Identification: You choose exactly which coins to sell, identified by purchase date, price, and amount. This gives you the most control but requires meticulous record-keeping.

Whatever method you choose, you must apply it consistently and be able to specifically identify each lot. Clarity's cost basis tracking supports all three methods and uses FIFO by default, with lot-level gain and loss tracking built in.

DeFi Tax Complications

Decentralized finance introduces layers of complexity that make traditional crypto taxes look simple:

• Token swaps on DEXs:Each swap is a taxable event. If you swap ETH for USDC on Uniswap, you've disposed of ETH and need to calculate the gain or loss.
• Liquidity pool tokens:Adding liquidity to an AMM pool may be treated as a taxable exchange. You're giving up two tokens and receiving LP tokens; the IRS hasn't issued definitive guidance, but the conservative approach is to treat this as a disposition.
• Wrapping and unwrapping: Wrapping ETH to WETH is a gray area. Some tax professionals treat it as a non-taxable like-kind exchange; others treat it as a taxable event. The safest approach is to track it as taxable.
• Yield farming rewards: DeFi yield is generally ordinary income when received, similar to staking rewards. The challenge is determining the fair market value of obscure tokens at the moment of receipt.
• Impermanent loss: Not directly deductible. However, when you withdraw from a liquidity pool, the actual gain or loss on your LP tokens is what matters for tax purposes.
• NFT transactions:Buying and selling NFTs follows the same capital gains rules. The IRS has proposed that certain NFTs may qualify as "collectibles" taxed at a higher 28% rate, though final guidance is still pending.

The Wash Sale Rule and Crypto

As of March 12, 2026, the federal wash sale rule still applies to stock and securities. Cryptocurrency is generally treated as property for federal tax purposes, so the classic wash sale rule does not currently apply to crypto in the same way it applies to stocks.

That means many taxpayers can still sell crypto at a loss and repurchase it without triggering the stock-style wash sale disallowance. But this is an area worth watching: Congress could change the rule, states can differ, and aggressive patterns can still create record-keeping and substantiation problems. If you plan to harvest losses, keep detailed lot records and verify the current rules before filing.

Reporting Crypto on Your Tax Return

Crypto dispositions are reported on Form 8949 and flow to Schedule D. Each transaction needs:

• Description of property (e.g., "2.5 BTC")
• Date acquired
• Date sold or disposed
• Proceeds (fair market value at time of sale)
• Cost basis
• Gain or loss

If you had hundreds or thousands of transactions across multiple exchanges, including Coinbase, Kraken, and others — and DeFi protocols, filling out Form 8949 manually is effectively impossible. This is where crypto tax software and tools like Clarity become essential; they aggregate your transaction history, calculate cost basis, and generate the required forms.

The IRS also asks a direct question on the front page of Form 1040: "At any time during the tax year, did you receive, sell, send, exchange, or otherwise acquire any digital assets?" You must answer truthfully. Checking "no" when the answer is "yes" is a red flag.

Starting with tax year 2026, crypto brokers and exchanges are required to issue Form 1099-DA (Digital Asset) reporting your gross proceeds from crypto transactions, similar to how brokerages report stock sales on Form 1099-B. This means the IRS will have more data than ever to cross-reference against your return.

Record-Keeping Is Everything

The biggest challenge with crypto taxes isn't the rates — it's the record-keeping. You need to track:

• Every purchase date, amount, and price in USD at the time
• Every sale, trade, or spending event
• Transfers between wallets (to prove they're not dispositions)
• Staking rewards, airdrops, and mining income
• Gas fees (which adjust your cost basis or are deductible as transaction costs)
• DeFi protocol interactions (swaps, LP deposits/withdrawals, yield claims)

If you used multiple exchanges and wallets over several years, reconstructing this history retroactively is painful. Start tracking now. Connect your exchanges and wallets to Clarity to build a complete transaction history automatically.

Common Crypto Tax Mistakes

These mistakes come up again and again:

• Not reporting at all: Exchanges report to the IRS. The IRS has sent letters to thousands of crypto holders about unreported income. With Form 1099-DA starting in 2026, this will only intensify.
• Forgetting crypto-to-crypto trades are taxable: Trading ETH for BTC is a disposition of ETH.
• Using the wrong cost basis:If you don't track specific lots, the IRS may assume zero cost basis — meaning your entire proceeds are treated as gain.
• Ignoring staking and airdrop income: These are ordinary income when received, not just when sold.
• Double-counting transfers as sales:Moving crypto between your own wallets is not a taxable event, but if your records don't distinguish transfers from sales, you might report phantom gains.
• Assuming crypto follows the stock wash sale rule: Crypto usually does not follow the classic federal wash sale rule today, but you still need accurate lot tracking and should verify current rules before filing.

How Clarity Helps With Crypto Taxes

Crypto tax preparation is uniquely difficult because transactions are scattered across centralized exchanges, self-custody wallets, and DeFi protocols. Clarity connects to your exchanges and reads on-chain wallet data to aggregate every transaction into a single view. Cost basis is calculated automatically using your preferred method (FIFO, HIFO, or specific identification), lot history stays organized across accounts, and your full transaction history is prepared for Form 8949 reporting.

This is where Clarity has a stronger product fit than generic tax explainers: it combines exchange imports, wallet activity, cost-basis tracking, and tax-ready exports in one place instead of forcing you to reconcile everything manually in spreadsheets.

What to Do Next

Start by gathering your complete transaction history from every exchange and wallet you've used. Most exchanges let you download CSV files of your trade history. For on-chain transactions, you'll need your wallet addresses to pull records from block explorers.

Connect your exchanges and wallets to Clarity to automatically track every transaction, calculate cost basis using your preferred method, and prepare the data you need for Form 8949. The earlier you start, the less painful tax season will be.
