Fee Deduction FAQ
I paid $500 in gas this year - now what?
Add each fee to the relevant transaction's basis or subtract from proceeds. If you have $10K gains and $500 in fees, you're taxed on $9,500.
Coinbase shows fees separately - use them?
Yes! Export your transaction history. Coinbase clearly shows fees per trade. Add buying fees to basis, subtract selling fees from proceeds.
What about failed transactions?
Gas paid on failed ETH transactions is trickier. Some treat it as a loss, others add to next successful transaction's basis. Document everything.
DEX fees vs CEX fees - same treatment?
Yes. Uniswap's 0.3% fee works just like Coinbase's commission. Add it to your cost basis for the tokens you received.
I paid fees in ETH, not USD - how to value?
Convert to USD at the time of the transaction. If you paid 0.01 ETH when ETH was $3,000, that's a $30 fee.
Can I deduct crypto tax software costs?
Maybe. If crypto is investment, it's harder. If it's a business (trader), software is a business expense. Consult a CPA.
Wire transfer fees to exchanges?
Debatable. Most conservative approach: not deductible. Aggressive: add to first purchase's basis. Keep records either way.
Priority/fast gas - deductible?
Yes, it's still a transaction fee. Whether you paid 20 gwei or 200 gwei, the full gas cost adds to basis or reduces proceeds.
How to track hundreds of small fees?
Use crypto tax software (Koinly, CoinTracker). They pull fees automatically from exchange APIs and blockchain data.
