How Cryptocurrency Taxes Work

Cryptocurrencies like bitcoin are treated as property by many governments around the world—including the U.S. Other forms of property that you may be familiar with include stocks, bonds, and real-estate.

Just like these other forms of property, cryptocurrencies are subject to capital gains and losses rules, and you need to report your gains, losses, and income generated from your crypto investments on your taxes.

For a complete and in-depth overview, please refer to our Complete Guide to Cryptocurrency Taxes.

How To Do Your Crypto Taxes

To do your cryptocurrency taxes, you need to calculate your gains, losses, and income from your cryptocurrency investments in your home fiat currency (e.g. US Dollar, Australian Dollar, etc.).

Once you have your calculations, you can fill out the necessary tax forms required by your country. If you are in the United States, you can learn which forms you need to fill out with our blog post: How to Report Cryptocurrency On Your Taxes.

Why Can't 1inch Generate My Tax Forms?

Many cryptocurrency investors use additional exchanges, wallets, and platforms outside of 1inch. Perhaps you also trade on Coinbase or earn interest from BlockFi. The trouble with 1inch's reporting is that it only extends as far as the 1inch platform. If you use additional cryptocurrency wallets, exchanges, DeFi protocols, or other platforms outside of 1inch, 1inch can't provide complete gains, losses, and income tax information.

How Does Cryptocurrency Tax Software Help?

By integrating with all of your cryptocurrency platforms and consolidating your crypto data, CoinLedger’s cryptocurrency tax software and crypto portfolio tracker are able to track your profits, losses, income, and generate accurate tax reports in a matter of minutes.

You can test out the software and generate a preview of your gains and losses completely for free by creating an account.

1inch is a decentralized exchange aggregator, so doing your 1inch taxes works a little differently than on a centralized exchange. Whether you file by hand or use crypto tax software, it comes down to four steps:

Gather your full on-chain 1inch history: every swap and reward, across every network you used it on.
Sort your activity. Moving crypto between your own wallets is not taxable, but disposals (like swaps) and crypto that comes in as income (like the 1INCH airdrop or staking rewards) are.
Calculate your capital gain or loss on each disposal, plus the value of any crypto income at the time you received it.
Report it on the right forms. In the US, capital gains go on Form 8949 and Schedule D, and crypto income goes on Schedule 1. These forms get included with your full tax return. Other countries have their own equivalents.

For a detailed explainer on reporting crypto, see our guide on how to report your cryptocurrency on your taxes.

Because 1inch is a decentralized protocol, it gives you no tax forms and no finished tax report: everything lives on-chain, and reconstructing it is your responsibility. That is where crypto tax software comes in. CoinLedger reads the wallet addresses you used on 1inch, pulls in your full on-chain history, connects it to every other wallet and exchange you use, and generates your tax forms automatically. More than 700,000 investors use it to file in minutes. Get started with a free account today, or keep reading to do it yourself.

Do you have to pay taxes on 1inch?

Yes. Cryptocurrency is treated as property, so in the US and most other countries your 1inch activity is subject to two kinds of tax:

Capital gains tax. When you swap one token for another through 1inch, that is a disposal, so you recognize a capital gain or loss based on how the price of the token you swapped away changed since you received it. This is true whether you use a classic swap or an intent-based order such as 1inch Fusion.
Income tax. When you earn crypto — for example, the 1INCH airdrop, or staking and delegation rewards — you recognize ordinary income equal to its fair market value at the time you received it.

For a full breakdown, read our complete guide to cryptocurrency taxes.

How is the 1inch airdrop taxed?

In December 2020, 1inch distributed 1INCH tokens to wallets that had used the protocol before a set snapshot date. An airdrop like this is treated as ordinary income, based on the fair market value of the tokens at the time they landed in your wallet. When you later dispose of airdropped tokens, you recognize a separate capital gain or loss based on how the price changed since you received them. The same treatment applies to 1INCH staking and delegation rewards.

How are gas fees taxed?

Gas fees you pay to acquire or dispose of a token can be added to that asset's cost basis or netted against your proceeds, which lowers your gain. Paying a gas fee in a token like ETH is itself a small disposal of that token.

What tax forms does 1inch provide?

None. 1inch is a decentralized protocol with no company taking custody of your funds or verifying your identity, so it issues no Form 1099-DA, 1099-MISC, or 1099-B.

You may have read that this was about to change, and that DeFi protocols might have to report like brokers. They do not. The IRS rule that would have required decentralized platforms to report was repealed in April 2025, so no reporting requirement applies to a protocol like 1inch. (The separate rule requiring centralized exchanges to issue Form 1099-DA still stands, but it does not apply to non-custodial protocols.) Reconstructing your history and self-reporting it remains your responsibility.

Does 1inch report to the IRS?

No. Because it is decentralized and collects no personal information, 1inch does not report your activity to the IRS.

That does not make your activity invisible. Transactions on public blockchains like Ethereum are permanent and visible on-chain, and the IRS has worked with analytics firms such as Chainalysis to link wallet addresses to the people behind them, especially once funds touch a KYC exchange. And no reporting does not mean no tax: US persons owe tax on every disposal and all crypto income, and must self-report it whether or not anyone sends a form.

Why isn't my 1inch tax report accurate on its own?

Your wallet's 1inch history only shows the swaps and transfers tied to that wallet. Because investors move crypto across many wallets, chains, and exchanges, no single source can see the original cost basis of assets you moved in from somewhere else, so it cannot calculate your gains and losses correctly.

Example: why transfers break your cost basis

Sofia buys $1,000 of ETH on a centralized exchange. She moves it to her wallet, and later, when the ETH is worth $1,400, swaps it for another token through 1inch.

On its own, the 1inch swap looks like a $1,400 disposal, with no record of the $1,000 Sofia originally paid. Without her cost basis, her $400 gain cannot be calculated correctly.

The fix is to bring every wallet, chain, and exchange into one place so your cost basis follows your crypto everywhere it goes. That is exactly what crypto tax software like CoinLedger does.

How to file your 1inch taxes in minutes

Because 1inch is on-chain, CoinLedger imports your activity directly from the wallet address you used. No API keys or file uploads are required.

In CoinLedger, go to Add Account and choose the blockchain you used 1inch on (for example Ethereum), then paste your public wallet address.
CoinLedger scans that address and automatically imports and classifies your 1inch swaps and rewards.
Repeat for each network you used 1inch on, since 1inch runs across Ethereum, BNB Chain, Arbitrum, Optimism, Base, Polygon, Avalanche, and more, and each chain has its own address history.

Anything from a contract CoinLedger does not yet recognize imports as uncategorized and can be labeled in the Review step.

Once your transactions are in, CoinLedger matches your transfers, calculates your gains, losses, and income, and produces a complete tax report. You can file it yourself, hand it to your tax professional, or import it into TurboTax, TaxAct, or H&R Block.
