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.
