TL;DR
Most fees are imported automatically, but you can also enter them manually in the Transactions page (set to Table View: Extended). Fees in the same trade currency are already included in purchase/sale values. Third-currency fees (e.g. BNB on Binance) must be entered separately as Other Fee.
How fees are handled in CoinTracking
Automatically imported fees: If fees are in the same currency as the trade pair, they are already included in purchase and sale values (CSV or API imports).
Manual entry: You may need to manually add fees when they are not automatically captured, especially third-currency fees.
Informational value: The fee field itself is mainly informational. The actual amounts shown in purchase/sale values are what matter for calculations.
Examples of fee entries
Buy with fiat fee:
Buy 1 BTC for 500 USD with a 5 USD fee
→ Entry: Buy = 1 BTC, Sell = 505 USD, Fee = 5 USD
Buy with coin fee:
Buy 1 BTC for 500 USD with a 0.01 BTC fee
→ Entry: Buy = 0.99 BTC, Sell = 500 USD, Fee = 0.01 BTC
Spend with fee:
Spend 0.2 BTC on goods with 0.001 BTC fee
→ Entry: Spend = 0.201 BTC, Fee = 0.001 BTC
Transfer with fee:
Transfer 1 BTC with 0.001 BTC fee
→ Withdrawal = 1.001 BTC from Wallet A, Fee = 0.001 BTC
→ Deposit = 1 BTC into Wallet B
Handling deposit fees
Rarely, deposit fees may cause mismatches in the Missing Transactions Report.
Options:Add the deposit fee to the withdrawal entry.
Or, create a separate entry with transaction type Other Fee.
Third-currency fees
If fees are taken in a third currency (not part of the buy/sell pair), they won’t reduce balances automatically.
Example: BNB used to pay fees on Binance.
Solution: Create an additional Other Fee entry.
This is automatically done with Binance CSV/API imports.
Tax report considerations
In advanced tax report settings, you can include fees into cost basis and gains via fiat values.
Every fee transaction can have a taxable effect since the coin used for the fee may have gained or lost value since purchase.
A decrease in the coin used for fees is a deductible loss, while needing fewer coins to pay the fee counts as a taxable gain.
