Transaction Fee Deductibility

Transaction fee deductibility refers to the ability to subtract fees paid during trading from the gross proceeds of a sale to determine the net taxable gain or loss. This includes exchange commissions, withdrawal fees, and blockchain network gas fees.

Properly accounting for these costs is a simple but often overlooked way to reduce taxable income. In high-frequency trading or complex derivative strategies, these fees can accumulate to a significant amount over a year.

All fees must be documented with receipts or transaction hashes to be considered valid deductions. In many cases, these fees are treated as an adjustment to the cost basis of the asset.

Failing to include these costs leads to an overstatement of profit and unnecessary tax payments.
