How to calculate tax on ETH gas fees
At the time of writing gas price is 180 Wei and to do a trade on Uniswap cost around $100 in ETH. This is a significant amount for most users, and adding this to your cost basis is an important part in minimizing your taxes. But in most circumstances you will also need to consider the capital gains realized on the ETH you are spending for gas.
Example:
Date | Trade | Currency | Price | Quantity | Gas (ETH) | ETH Price |
---|---|---|---|---|---|---|
1st Jan 2017 | Buy | ETH | 30 | 2 | - | - |
4th Oct 2020 | Buy | SUSHI | 200 | 1 | - | - |
6th Feb 2020 | Sell | SUSHI | 1000 | 1 | 0.1 | 1000 |
6th Feb 2020 | Buy | DAI | 1000 | 1 | - | - |
In the above example Satoshi sells $1,000 worth of SUSHI on Uniswap for DAI. To do this he pays $100 in gas using ETH. He originally bought his Sushi for $200, and his ETH for $30 each. Satoshi realized a profit of $800 by selling his sushi (1000 - 200), but he also had $100 worth of gas fees, so he overall realized gain is $700 (1000 - 200 - 100). However he originally bought ETH at $30, and at the time of the transaction ETH was worth $1000, so Satoshi needs to consider the gain in ETH. This would be calculated as $97 ((1000 - 30) * 0.1). As you can see there is a lot going on here.
