How are MetaMask transactions taxed?

The tax you’ll pay on your MetaMask transactions depends on where you live and the transactions you’ve made, but in general, your crypto is subject to Capital Gains Tax and Income Tax.

Does MetaMask report to the IRS?

It's unlikely MetaMask reports to the IRS as a non-custodial ETH wallet - even if it is one of the leading non-custodial wallets available! MetaMask doesn't require users to complete KYC verification, so they have very little personal information about their users.

How do I file my MetaMask taxes?

You need to report gains, losses and income from crypto investments to your tax office, generally as part of your annual tax return. This includes any gains, losses or income relating to your MetaMask wallet.

How to connect Koinly and MetaMask automatically

The best way to integrate MetaMask with your Koinly account is using the MetaMask browser extension. This is available on Chrome, FireFox and Brave. You can install the MetaMask browser extension on any of these browsers and we highly recommend doing this before you follow our API steps below.

On Koinly

  1. Sign up or log in to your Koinly account and go to the wallets page.
  2. Select add new wallet: MetaMask.
  3. Select set up auto-sync.

In Browser:

  1. Select the MetaMask extension icon in the top right corner of your browser.
  2. From the drop down tab at the top, find the Ethereum Mainnet option.
  3. Under the account name, copy the public address.

MetaMask instructions Koinly

Back to Koinly:

  1. Paste the public address into the public address or key box.
  2. Select secure import.

Syncing other networks

Syncing your MetaMask wallet will sync all of your Ethereum transactions. To connect to other networks like Binance Smart Chain or Polygon, you'll need to create separate wallets for these networks in Koinly. You can do this by logging into your Koinly account and going to wallets. Instead of connecting MetaMask, find the network you want to connect, for example Polygon or Binance Smart Chain. Then find the public address for these networks in your MetaMask browser extension and copy and paste these into Koinly to import.

Important

1. Auto-syncing your MetaMask data takes a couple of minutes on Koinly. This is normal, Koinly is just working through your transactions to identify which are taxable events and which aren't.

2. Once your data is imported, you might notice a small yellow warning icon next to your MetaMask wallet. This icon indicates an issue with imported data, click on it to find out the precise issue. You can learn more about how to resolve this in this guide.

3. MetaMask doesn't give the option to export CSV files, although you can use some third-party providers to export CSV data directly from the ETH blockchain.

4. Please note, Koinly does not automatically handle Uniswap V3 liquidity transactions like V2 liquidity transactions.

5. Some users may need to tag certain transactions themselves - in particular, staking and farming transactions. Find out more about how to tag staking transactions and farming transactions.
