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.
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 OpenSea Generate My Tax Forms?
Many cryptocurrency investors use additional exchanges, wallets, and platforms outside of OpenSea. Perhaps you also trade on Coinbase or earn interest from BlockFi. The trouble with OpenSea's reporting is that it only extends as far as the OpenSea platform. If you use additional cryptocurrency wallets, exchanges, DeFi protocols, or other platforms outside of OpenSea, OpenSea 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.
OpenSea is a self-custody NFT marketplace, so doing your OpenSea 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 OpenSea history: every NFT you bought, sold, or minted, and any rewards, across every network you used.
Sort your activity. Moving crypto or NFTs between your own wallets is not taxable, but buying and selling NFTs, and crypto that comes in as income, are.
Calculate your capital gain or loss on each disposal, plus the value of any 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 income goes on Schedule 1. These forms get included with your full tax return. Other countries have their own equivalents.
Because OpenSea is non-custodial, 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 OpenSea, pulls in your full NFT 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.
How are NFTs taxed?
NFTs are taxed as property, like other crypto, but with a few twists worth knowing:
Buying an NFT with crypto is a disposal of that crypto. You recognize a capital gain or loss on the crypto you spent, based on how its price moved since you acquired it, even before you think about the NFT itself.
Selling or flipping an NFT is a disposal of the NFT. You recognize a capital gain or loss based on how its value changed since you acquired it. An NFT-for-NFT trade is valued at fair market value.
Some NFTs may be "collectibles," which the IRS has proposed could carry a higher maximum long-term capital gains rate of 28%. This is still preliminary guidance, so if you hold NFTs long term it is worth confirming with a tax professional.
Creator income. If you mint and sell your own NFTs, your primary sales and ongoing royalties are ordinary income at their fair market value when received.
A note on minting and gas: minting an NFT is not itself income, but paying the mint cost or gas in crypto is a disposal of that crypto, and those costs become part of the NFT's cost basis. For more, see our guide to how NFTs are taxed.
What tax forms does OpenSea provide?
None. OpenSea is a non-custodial marketplace where you connect your own wallet, so it holds no personal information and does not act as a broker. It issues no Form 1099-DA, 1099-MISC, or 1099-B.
You may have read that NFT platforms would be required to start reporting to the IRS. They are not. The IRS rule that would have required decentralized platforms to report was repealed in April 2025, so no reporting requirement applies to a marketplace like OpenSea. (The separate rule requiring centralized exchanges to issue Form 1099-DA still stands, but it does not apply to non-custodial marketplaces.) Reconstructing your history and self-reporting it remains your responsibility.
That does not make your activity invisible. NFT 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 NFT sale and every crypto disposal, and must self-report it whether or not anyone sends a form.
Why isn't my OpenSea tax report accurate on its own?
Your wallet's OpenSea history only shows the NFT activity tied to that wallet. Because investors move crypto and NFTs 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 buying an NFT is already taxable
Mei buys $1,500 of ETH on a centralized exchange. Later, when that ETH is worth $2,000, she uses it to buy an NFT on OpenSea.
Even before she ever sells the NFT, Mei has a $500 capital gain on the ETH she spent, because buying the NFT was a disposal of her crypto. Without her original cost basis in one place, that gain is easy to miss.
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 OpenSea taxes in minutes
Because OpenSea is on-chain, CoinLedger imports your history 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 OpenSea on (for example Ethereum, or Solana), then paste your public wallet address from that wallet.
CoinLedger reads your OpenSea buys and sells directly from the chain and classifies them.
CoinLedger also scans your address for activity on other chains and prompts you to import each, since OpenSea now supports Ethereum, Polygon, Solana, Base, and more.
NFT and smart-contract transactions do not always import cleanly, so review your NFT activity and label anything that comes in as uncategorized. Full steps are in our OpenSea blockchain import guide.
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.
