Does MetaMask Report to the IRS?

MetaMask is one of the most popular non-custodial crypto wallets, but can the IRS see your MetaMask transactions? Find out what the IRS knows in our guide.

Does MetaMask report to the IRS?

No. MetaMask doesn’t report to the IRS and isn’t required to under existing guidance. 

Because MetaMask is a non-custodial wallet, it’s not classified as a crypto broker (which are required to report to the IRS via Form 1099-DA from 2026). 

Up until April 2025, under new guidance, DeFi services were potentially going to be included in new reporting requirements, but the current administration has since repealed this.

However, if you’re tempted not to report your MetaMask transactions because you don’t think the IRS knows about them, think again.

How could the IRS know about my MetaMask transactions?

Blockchains are transparent by design. Anyone can inspect the activity tied to a public address, including tax agencies like the IRS.

Once your identity is connected to an address, your on-chain history is effectively open. MetaMask is a self-custody wallet and doesn’t require KYC for general use, but interactions through third-party services (e.g., card purchases, on-ramps, off-ramps) can create records that authorities may request. Investigators also use blockchain analytics to link addresses and trace funds.

Centralized exchanges have likewise been ordered to share customer information, which can include the wallet addresses people use for deposits and withdrawals.

The bottom line: report your crypto gains, losses, and income accurately. Skipping or underreporting can trigger audits, fines, and interest.

How do I report my MetaMask taxes to the IRS?

You must disclose your crypto disposals and income tied to wallets you use with MetaMask. Capital gains and losses from sales, trades, or spending go on Form 8949 and Schedule D. Any crypto income (staking rewards, airdrops, interest, freelance payments, etc.) belongs on Schedule 1 or Schedule C if it’s part of a trade or business.

Since tracking this data can be complex, most investors opt to use a crypto tax calculator like Koinly to make it simpler.
