Most United States (U.S.) crypto investors know that selling Bitcoin for dollars can trigger taxes. However, swapping Ethereum (ETH) for Solana (SOL), converting Bitcoin (BTC) to Wrapped Bitcoin (wBTC), or exchanging tokens across blockchains can also create a taxable event because the Internal Revenue Service (IRS) treats digital assets as property for U.S. tax purposes.
While the basic rule is straightforward, wrapping and bridging can be more nuanced. The tax treatment depends on how the transaction is structured and the assets involved. This guide explains how these transactions can be taxed and what you may need to report in 2026.
Key Takeaways:
- The IRS treats cryptocurrency as property, every disposal triggers a taxable event.
- Crypto-to-crypto swaps are taxable, irrespective of fiat involvement.
- Wrapping tokens is treated as a crypto-to-crypto trade subject to capital gains tax.
- Bridging crypto may or may not be taxable, depending on how the bridge is structured.
- All digital asset transactions must be reported on Form 1040, including crypto-to-crypto trades.
Is Crypto-to-Crypto Trading Taxable In The U.S.?
Yes, and the IRS has made this increasingly difficult to overlook. Whether you’re swapping on a centralized exchange (CEX) or executing trades through a Decentralised Finance (DeFi) protocol, the same rules apply across the board. Exchanging one digital asset for another is treated the same as selling a stock and using the proceeds to buy a different one.
According to the IRS FAQs on Virtual Currency Transactions, when you exchange virtual currency for other virtual currency, you must recognize a capital gain or loss equal to the difference between the fair market value of the asset received and the adjusted basis of the asset you gave up.
How Are Crypto-to-Crypto Swaps Taxed In The U.S.?
A crypto swap is any direct exchange of one digital asset for another without first converting to U.S. dollars. Whether you execute the trade on a centralized exchange or a decentralized protocol, the tax treatment is identical, you disposed of one asset and acquired another, and the IRS wants to know the gain or loss on what you gave up.
Crypto-to-Crypto Swaps for Profit
When the fair market value (FMV) of the crypto you’re swapping away is higher than what you originally paid for it, the difference is a realized capital gain. That gain is taxable in the year the swap occurs, regardless of whether you withdraw anything to your bank account.
Crypto-to-Crypto Swaps at a Loss
A swap that results in a loss isn’t just a bad trade, it’s also a reportable event that can work in your favor. Capital losses from crypto swaps can be used to offset capital gains from other transactions, reducing your overall tax liability for the year.
Crypto-to-Stablecoin Swaps
Swapping into a stablecoin like USDC or USDT doesn’t escape the IRS’s attention. Despite the 1:1 peg to the U.S. dollar, stablecoins are classified as property rather than currency under federal tax law. Trading any cryptocurrency for a stablecoin is treated as a disposal of the original asset, and any gain or loss must be reported.
NFT Swaps
Trading a non-fungible token (NFT), whether for another NFT or for a cryptocurrency, falls under the same crypto-to-crypto swap guidelines. The gain or loss is calculated based on the FMV of the NFT you disposed of at the time of the trade, minus your original cost basis in that NFT.
DeFi Swaps
Swapping tokens on a decentralized exchange like Uniswap or Raydium is taxed the same way as swaps on a centralized platform. The IRS makes no distinction between on-chain and off-chain trades, the disposal of one token for another is a taxable event either way. What adds complexity in DeFi is gas fees, which are paid in crypto and are themselves a form of disposal, potentially creating a small additional gain or loss on the tokens used to cover those fees.
How Is Wrapping Crypto Taxed In The U.S.?
The IRS has not ruled directly on whether wrapping counts as a taxable event. Notice 2024-57 names wrapping and unwrapping as an open category, though only for broker reporting purposes. Most tax preparers still apply the standard swap rules, treating the wrap as a disposal.
Tax on Wrapping Bitcoin
Yes. Even though 1 BTC and 1 wBTC are worth nearly the same amount, typically within a fraction of a percent of each other, they are two different coins on two different blockchains. The IRS treats the conversion as a crypto-to-crypto trade, meaning you must calculate the capital gain or loss based on your original BTC cost basis and the FMV of the wBTC you receive. The gain may be minimal, but it is still a reportable event.
Tax on Wrapping Ethereum
Wrapping ETH into wETH follows the same logic. ETH and wETH are separate tokens, one is the native Ethereum asset, the other is an ERC-20 compatible version used in DeFi protocols. Converting between them is a disposal attracting taxation, and the capital gain or loss is calculated the same way as any other crypto swap.
Tax on Unwrapping Tokens
Converting a wrapped token back to its original form is also a taxable event. The logic is the same as the initial wrapping: you are disposing of one asset (the wrapped token) and acquiring another (the original), and any gain or loss between your cost basis in the wrapped token and its FMV at the time of unwrapping must be reported.
How Is Bridging Crypto Taxed In The U.S.?
Unlike simple swaps, whether a bridge transaction is taxable depends entirely on the mechanics of how that specific bridge operates. Some bridges move your asset without a true disposal occurring, others effectively destroy and recreate it, which the IRS would treat as a sale.
Native Token Bridge (Lock and Wrap)
When a bridge locks your tokens in a smart contract and issues a wrapped equivalent on the destination chain, you still own the underlying asset, it hasn’t been disposed of. This structure is generally considered a non-taxable transfer, similar to moving crypto between two wallets you control. However, if the bridge instead destroys and reissues tokens rather than locking and wrapping them, the transaction crosses into taxable territory.
Burn and Mint Bridge
A burn-and-mint bridge destroys your original tokens and mints new ones on the destination chain. The destruction of the original token is treated as a disposal by the IRS, meaning a taxable event has occurred, and any capital gain or loss must be reported based on the FMV at the time of burning, versus your original cost basis.
Cross-Chain Swaps
When you exchange one cryptocurrency for a different one while bridging, for instance, sending SOL on Solana and receiving AVAX on Avalanche, that’s a cross-chain swap. The IRS treats this identically to a standard crypto-to-crypto swap: you disposed of one asset and acquired another, and any gain or loss on what you gave up is reportable.
Bridge Fees Paid in Tokens
Paying bridge fees with cryptocurrency, which is standard practice, is itself a taxable event. The IRS treats fee payments made in crypto as a disposal of those tokens. Any gain or loss between your cost basis in the fee tokens and their FMV at the time of payment must be calculated and reported, even if the amounts are small.
How to Report Crypto-to-Crypto Trades on Your Tax Return?
Reporting crypto-to-crypto trades correctly means working through a specific sequence of steps, using the right IRS forms, and making sure every transaction, including swaps, wraps, and bridges, is accounted for individually.
Step 1: Answer the Digital Asset Question on Form 1040
Every U.S. taxpayer must answer the digital asset question on Form 1040. If you dispose of crypto through a swap, wrap, or bridge, the answer is “Yes.” A same-wallet transfer with no disposal, like a lock-and-wrap bridge, does not require it. Answering “No” when a disposal occurred risks IRS penalties and scrutiny, a step no investor should take.
Step 2: Gather All Transaction Records
Collect your complete transaction history from every platform you used, centralized exchanges, decentralized exchanges (DEXs) protocols, wallets, and bridge platforms. Many exchanges issue Form 1099-DA for digital asset transactions, so check whether you’ve received one before you begin calculating.
Step 3: Calculate Gain or Loss on Each Trade
Go through every swap, wrap, and bridge transaction individually. For each one, determine the FMV of the asset disposed of at the exact time of the transaction, subtract your cost basis, and record the result as either a capital gain or loss. No transaction gets bundled with another.
Step 4: Report Each Transaction on Form 8949
Every taxable crypto-to-crypto trade, whether a swap, wrap, or bridge, is listed individually on Form 8949. Short-term trades (held ≤1 year) go in Part I and long-term trades (held >1 year) go in Part II. Each line requires the asset description, date acquired, date sold, proceeds, cost basis, and resulting gain or loss.
Step 5: Summarize on Schedule D
Once Form 8949 is complete, the short-term and long-term totals are transferred to Schedule D. This is where the IRS gets a consolidated view of your overall capital gains position for the year across all asset types.
Step 6: File Before the Deadline
Submit your return and pay any taxes owed before the filing deadline. If you have significant crypto trading activity, making quarterly estimated tax payments throughout the year helps you avoid underpayment penalties at filing time.

Conclusion
Crypto-to-crypto trading is one of the most commonly misunderstood areas of U.S. tax law. The idea that taxes only apply when cash hits your account is a misconception that has caught many investors off guard. Every swap, every wrapped token conversion, and every taxable bridge transaction is a disposal of property, and the IRS expects each one to be reported individually
With broker reporting expanding in 2026 and blockchain analytics becoming more sophisticated, the window for overlooked transactions is narrowing. KoinX ensures your entire crypto-to-crypto trading history is tracked, calculated, and reported correctly before the deadline arrives.
Frequently Asked Questions
Are Gas Fees on Crypto Swaps Tax Deductible?
Gas fees paid in cryptocurrency are treated as a disposal of property, which may result in a small capital gain or loss. In some cases, the fee amount can be treated as a deductible expense that offsets proceeds from the swap.
Do I Need to Report Crypto-to-Crypto Trades if I Made a Loss?
Yes. Capital losses from crypto-to-crypto trades must still be reported on Form 8949, even if no gain was realized. The upside is that those losses can be used to offset capital gains from other transactions. Additionally, up to $3,000 in net capital losses ($1500 if married filing separately) per year can be applied against ordinary income, reducing your overall tax bill.
Can Crypto-to-Crypto Trade Losses Be Carried Forward to Future Tax Years?
Yes. If your total capital losses from crypto trades exceed your gains in a given year, the excess beyond the $3,000 annual ordinary income deduction limit can be carried forward indefinitely into future tax years, offsetting gains in those years until the loss is fully used up.
Will the IRS Receive My Crypto Swap Data Directly From Exchanges in 2026?
Yes. Starting with 2025 transactions reported in 2026, exchanges must issue Form 1099-DA to you and the IRS. These forms report gross proceeds from digital asset sales. DeFi activity, wallet-to-wallet transfers, and on-chain swaps are not yet covered under current broker reporting rules. Wrapping and unwrapping transactions are also exempt from this reporting for now, under Notice 2024-57.
