Gas fee: what it means for crypto tax
A gas fee is the cost of executing a transaction on a blockchain. Fees paid to acquire an asset can often be added to its cost basis, and fees on a disposal can reduce proceeds, so tracking them can lower your taxable gain.
General information, not tax advice. Crypto tax rules differ by country and change over time, verify against your country's guidance or a qualified advisor.
An example
Pay 15 in gas to buy a token and that 15 can raise its cost basis, shrinking a future gain.
Why it matters for your tax
Over hundreds of transactions, gas handled correctly meaningfully reduces a taxable gain, and ignored, it inflates it, which is why fees are worth capturing.
