Yes, swapping crypto is taxable. The IRS treats cryptocurrency as property, so trading one digital asset for another is legally the same as selling the first for dollars and immediately buying the second, and that “sale” produces a capital gain or loss you must report for the year of the swap.1Internal Revenue Service. Notice 2014-21 No cash needs to move. The gain is measured at the moment of the trade in U.S. dollars, and the tax is due whether or not you ever convert back to dollars.
Why a Coin-for-Coin Trade Is a Taxable Event
The IRS set the rule in 2014 with Notice 2014-21, classifying virtual currency as property rather than currency.1Internal Revenue Service. Notice 2014-21 Property rules mean disposition rules: give up one asset, receive another, realize the gain or loss on what you gave up.
Some taxpayers used to argue crypto swaps qualified as like-kind exchanges under Section 1031, deferring the tax. The Tax Cuts and Jobs Act shut that door. Section 1031 now applies only to real property, and it explicitly excludes personal property and intangible assets.2Office of the Law Revision Counsel. 26 U.S. Code 1031 There is no deferral available for a crypto-to-crypto trade today.
Stablecoin Swaps Count Too
Moving into USDC or USDT is not a free move. The IRS lists stablecoins as digital assets, and exchanging any digital asset for another digital asset is reportable.3Internal Revenue Service. Taxpayers Need to Report Crypto, Other Digital Asset Transactions on Their Tax Return If you bought ETH at $1,500 and swapped it into USDC when ETH was trading at $3,000, you realized a $1,500 gain, even though the destination is pegged to the dollar.
Wrapping and unwrapping, such as ETH to WETH, is less settled. The IRS has not issued definitive guidance on whether wrapping is a taxable disposition, and Notice 2024-57 temporarily exempts wrapping and unwrapping from broker reporting while the agency works through the issue.4Internal Revenue Service. Digital Assets The reporting exemption does not remove your own obligation to report if a transaction is taxable. Track these trades and get a professional read on whether to treat them as dispositions.
How to Calculate the Gain or Loss
The math is simple: fair market value of what you received, minus your cost basis in what you gave up, measured in U.S. dollars at the time of the swap.4Internal Revenue Service. Digital Assets Positive number, capital gain. Negative, capital loss.
Cost basis is what you originally paid for the coin you are disposing of, plus any fees you paid to acquire it. Bought 1 BTC for $30,000 with a $50 fee? Your basis is $30,050. Swap that BTC into ETH when BTC is worth $65,000, and your proceeds are $65,000. The gain is $34,950. Fees paid to execute the swap itself can also adjust basis.
If you have bought the same coin at different prices over time, you need to know which lot you are disposing of. FIFO is the default: the earliest coins you bought are the ones you are treated as selling first.5Internal Revenue Service. Frequently Asked Questions on Virtual Currency Transactions Specific identification is available if you keep records tying each unit’s disposition to its acquisition date, time, basis, and fair market value. That gives you room to pick a higher-basis lot to shrink a gain, or a lot held over a year to reach the long-term rate. Without adequate records, FIFO applies automatically.
How Long You Held It Sets the Rate
Holding period is the difference between an ordinary-income tax bill and a much smaller one. The clock starts the day after you acquired the coin you are giving up. One year or less at the moment of the swap, short-term. More than one year, long-term.6Internal Revenue Service. FS-2007-19, Reporting Capital Gains The coin you receive starts a fresh holding period from the day after the swap.
Short-term gains are taxed at your ordinary income rate. Federal rates for 2026 run from 10% to 37%.7Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Long-term gains fall into the preferential 0%, 15%, or 20% brackets based on taxable income. The spread between the two treatments is often 15 to 20 percentage points, which is a serious argument for waiting past the one-year mark before executing a swap when you can.
High earners owe more on top. The 3.8% net investment income tax applies to the lesser of your net investment income or the amount your modified AGI exceeds $200,000 single, $250,000 married filing jointly, or $125,000 married filing separately.8Internal Revenue Service. Topic No. 559, Net Investment Income Tax Crypto swap gains count as investment income, so a top-bracket long-term gain can effectively be taxed at 23.8%.
Losses, and the Wash Sale Question
A losing swap has value at tax time. Capital losses offset capital gains dollar for dollar within their category, and any net loss beyond that can offset up to $3,000 of ordinary income per year ($1,500 if married filing separately). Losses above that limit carry forward indefinitely.9Internal Revenue Service. Topic No. 409, Capital Gains and Losses Twenty thousand in gains from one swap and fifteen thousand in losses from another leaves you with $5,000 of taxable gain.
The wash sale rule under IRC Section 1091, which blocks stock investors from claiming a loss when they rebuy a substantially identical security within 30 days, does not apply to crypto under current federal law. The rule is written for securities, and the IRS classifies crypto as property.1Internal Revenue Service. Notice 2014-21 You can currently sell a coin at a loss and buy it right back. Congress has proposed extending the wash sale rule to digital assets, and if that passes, this window closes. Check the current status before relying on the strategy.
Records to Keep for Every Swap
The IRS expects you to substantiate every number on your return.4Internal Revenue Service. Digital Assets For each swap, keep the date and time, the fair market value in U.S. dollars of both sides at that moment, the cost basis of what you gave up, any transaction and network fees, and, if you use specific identification, the records linking the exact units disposed of to their acquisition data.5Internal Revenue Service. Frequently Asked Questions on Virtual Currency Transactions
If you cannot document basis at all, the IRS treats basis as zero and the full proceeds as gain. This bites hardest when you received crypto as a gift without the donor’s records, or when an exchange has closed and you no longer have access to your history. Pull transaction histories from exchanges regularly instead of waiting for filing season.
How to Report a Crypto Swap
Three forms carry the transaction through your return.
First, Form 1040 asks a yes-or-no question about whether you received, sold, exchanged, or otherwise disposed of a digital asset during the year.10Internal Revenue Service. Determine How to Answer the Digital Asset Question A swap means yes. Answering no when you had reportable activity is the kind of flag the IRS uses to select returns for review.
Second, each swap gets its own line on Form 8949: acquisition date of what you disposed of, date of the swap, proceeds (the dollar value of what you received), and cost basis. Short-term transactions go in Part I, long-term in Part II, using the boxes designated for digital assets.11Internal Revenue Service. Instructions for Form 8949 (2025) Hundreds of swaps means hundreds of rows unless a broker’s basis-reported 1099 covers them cleanly.
Third, the totals from Form 8949 flow onto Schedule D, which combines short-term and long-term results into the net figure that lands on your Form 1040.
Form 1099-DA and the Cost of Skipping It
Starting in 2026, crypto brokers must report certain digital asset transactions to the IRS on Form 1099-DA.12Internal Revenue Service. Treasury, IRS Issue Proposed Regulations to Make It Easier for Digital Asset Brokers to Provide 1099-DA Statements Electronically The IRS gets its own copy directly from the exchange, and mismatches with your return will generate notices. Some transactions, including wrapping, liquidity provider activity, and staking, are temporarily exempted from broker reporting under Notice 2024-57, but the exemption is only about who sends the form. Your reporting obligation on taxable transactions is unchanged.4Internal Revenue Service. Digital Assets
The IRS has said that inaccurate reporting of digital asset income can result in accrued interest and penalties.3Internal Revenue Service. Taxpayers Need to Report Crypto, Other Digital Asset Transactions on Their Tax Return The accuracy-related penalty under IRC Section 6662 adds 20% of the underpaid tax when the understatement is due to negligence or is substantial, and interest runs from the original due date of the return.13Office of the Law Revision Counsel. 26 U.S. Code 6662 With 1099-DA in effect and the digital asset question on every Form 1040, unreported swaps are far more visible than they used to be.
