Is Converting Crypto Taxable? Calculations, Rates, and Reporting

Yes. Converting crypto is taxable under federal law, even when no dollars change hands and even when you swap directly from one token into another. The IRS treats digital assets as property, so trading Bitcoin for Ethereum, swapping into a stablecoin, or using one token to buy another on a decentralized exchange is a disposal that produces either a capital gain or a capital loss you have to report.¹

Why the Swap Itself Is a Taxable Event

Notice 2014-21 classified virtual currency as property for federal income tax purposes, and that single classification does the work. When you exchange one digital asset for another, the IRS views it as a disposal of the first asset at its current fair market value. If that value exceeds what you originally paid, you have a taxable gain. If it’s lower, you have a deductible loss.¹

The obligation attaches the moment the trade executes. It doesn’t matter whether the conversion happens on a centralized exchange, a decentralized protocol, or a direct peer-to-peer transfer. It doesn’t matter that you never touched fiat. Disposing of one token in exchange for another is enough.²

Which Conversions Count

Swapping into a stablecoin like USDC or USDT feels like moving to safety, but the IRS treats stablecoins as property just like any other token. Trading Bitcoin for USDC is a taxable conversion in the same way trading Bitcoin for Ethereum is. The peg to the dollar doesn’t give it special treatment; you still calculate gain or loss against your original cost.

The same logic applies to buying an NFT with crypto, providing liquidity to a DeFi pool, or routing a trade through a decentralized exchange. Each is a disposal. If the value of the token you gave up has risen since you acquired it, you owe tax on the difference.

What Doesn’t Trigger Tax

Moving crypto between wallets you own is not a taxable event. Sending Bitcoin from a Coinbase account to your own hardware wallet is not a conversion, because you still hold the same asset. That remains true even if the exchange sends you an information return for the transfer.²

Some holders have asked whether a token-for-token swap qualifies as a like-kind exchange under Section 1031, which would let them defer the gain. It doesn’t. Since 2018, like-kind treatment has been limited to real property, and the IRS concluded that even before that change, crypto-to-crypto swaps did not qualify.

How To Calculate Your Gain or Loss

The math is direct. Take the fair market value of the new token you received at the moment of the swap, and subtract your adjusted basis in the token you gave up. A positive result is a capital gain. A negative result is a capital loss.¹

Say you bought 1 ETH for $2,000 and later swapped it for another token when that ETH was worth $3,500. Your gain is $1,500. Receiving a different token rather than cash doesn’t change the calculation. Both sides of the trade are measured in U.S. dollars at the time each transaction occurred.

Short-Term vs. Long-Term Rates

How long you held the original token before converting it decides the rate. If you held it for one year or less, the gain is short-term and taxed at your ordinary income rate, which runs from 10% to 37%. Hold it longer than a year and the gain qualifies for long-term capital gains rates of 0%, 15%, or 20%.³

For tax year 2026, long-term rates for single filers break down as follows:

0% on taxable income up to $49,450
15% on taxable income from $49,451 to $545,500
20% on taxable income above $545,500

Married couples filing jointly get wider brackets: the 0% rate applies up to $98,900, the 15% rate up to $613,700, and the 20% rate above that. These thresholds adjust annually for inflation.

High earners face an added layer. If your modified adjusted gross income exceeds $200,000 as a single filer or $250,000 as a married couple filing jointly, the 3.8% Net Investment Income Tax applies on top of your capital gains rate. Those thresholds are not indexed for inflation, so more taxpayers cross them each year.⁴

Most states tax capital gains as regular income. Depending on where you live, state tax can add anywhere from nothing to over 13%, so a combined effective rate on a short-term crypto gain can approach 50% in the highest-tax states.

When the Conversion Produces a Loss

A loss on a swap can offset capital gains from other trades. If total losses for the year exceed total gains, you can deduct up to $3,000 of the remaining net loss against ordinary income ($1,500 if married filing separately). Anything beyond that carries forward to future years indefinitely.³

Crypto has an unusual advantage here, at least for now. The federal wash sale rule blocks stock investors from claiming a loss if they buy the same security back within 30 days. That rule, in Section 1091, applies specifically to “stock or securities,” and most tax professionals read general-purpose cryptocurrency as falling outside that category.⁵ In practice, that means you can sell a token at a loss, immediately buy it back, and still claim the loss. Legislation to close this gap has been proposed repeatedly, so it may not last.

Choosing Which Lot You Sold

Your cost basis is what you originally paid for the token, including transaction fees, gas fees, and exchange commissions at the time of purchase. Overstate the basis and you underreport gains; understate it and you overpay.

When you hold multiple lots of the same token bought at different prices, you need a method to decide which ones you’re disposing of. The IRS recognizes two:²

Specific identification. You pick exactly which units you are disposing of, identified by purchase date, price, or another unique marker. This gives you control over whether a given trade lands as a gain or a loss.
FIFO, or first in, first out. If you don’t specifically identify units, the IRS defaults to treating your earliest-purchased tokens as sold first. In a rising market, FIFO tends to produce larger gains because your oldest tokens usually carry the lowest basis.

What some tax software labels “LIFO” or “HIFO” is really specific identification applied strategically to pick the highest-cost lots first. They are not separate IRS-recognized methods; they are choices inside the specific identification framework.

For assets held by a broker after December 31, 2025, using specific identification requires that you notify the broker which units to sell no later than the date and time of the transaction, using whatever identifiers the broker designates, and that you keep records substantiating the identification.⁶ For assets in a self-custodied wallet, you have to record the identification in your own books no later than the time of the transfer.

You can switch between FIFO and specific identification from year to year without filing a special request. The only requirement is consistency within a given wallet or exchange account for the same tax year.

How To Report Crypto Conversions

Every federal return now includes a digital asset question on the first page of Form 1040. You have to answer “Yes” or “No” to whether you received, sold, exchanged, or otherwise disposed of any digital asset during the tax year. Answering “No” when you made taxable conversions is a red flag the IRS actively looks for.⁷

Individual conversions go on Form 8949. For each transaction you need:

Description of the asset sold, meaning the token name and quantity
Date acquired, meaning when you originally obtained the token you gave up
Date sold or exchanged, meaning when the conversion occurred
Proceeds, meaning the fair market value in dollars of the new token you received
Cost basis, meaning what you originally paid for the disposed token, including fees

Each conversion gets its own line. Short-term transactions (held one year or less) go in a different section from long-term ones.⁸ One exception: if your broker reported the transaction on a 1099-DA with basis included and no adjustments are needed, you can enter totals directly on Schedule D without listing each trade on Form 8949.

After Form 8949, the totals flow to Schedule D of Form 1040, which combines all capital gains and losses for the year into a single net figure.⁹

Form 1099-DA and Broker Reporting

Starting with transactions in 2025, centralized crypto brokers must report gross proceeds from digital asset sales and exchanges to the IRS on Form 1099-DA. Beginning with transactions in 2026, brokers must also report cost basis on certain transactions.¹⁰ In earlier years, exchanges issued 1099-MISC or 1099-B forms inconsistently or not at all. The new form gives the IRS a clear paper trail against your return, and mismatches will draw notices.

Decentralized platforms and non-custodial protocols are not yet covered. The IRS has said it will address those in future regulations. If you trade through DeFi, you are still on the hook for tracking and reporting every transaction yourself, typically by pulling data from blockchain explorers and keeping your own records.

Records and Penalties

You need records sufficient to document every acquisition date, disposal date, fair market value at both points, the number of units involved, and fees paid. Most centralized exchanges offer downloadable transaction histories. DeFi activity usually has to be reconstructed from blockchain explorers, which is slow but not optional. The IRS requires you to keep tax records for at least three years after the date you file the return they relate to.¹¹ With crypto, holding records longer is wise, since loss carryforwards depend on the original transaction data.

Two penalties can stack if you don’t report and pay on time. The failure-to-pay penalty is 0.5% of the unpaid tax for each month or partial month the balance stays outstanding, capped at 25%.¹² The failure-to-file penalty is steeper: 5% of the unpaid tax per month, also capped at 25%.¹³ When both apply in the same month, the failure-to-file penalty is reduced by the failure-to-pay amount, but the combined hit adds up quickly. If you owe crypto-related tax and can’t pay in full, filing on time and setting up a payment plan is almost always better than not filing at all.
