Crypto Tax Deductions and Expense Strategies (2026 Guide)

• Trading and investing expenses are not “miscellaneous itemized deductions” you can claim directly. Instead they usually adjust cost basis or reduce proceeds.

• Business-related crypto activity (e.g., full-time mining, OTC dealing, Web3 consulting) may deduct ordinary and necessary expenses on Schedule C.

• Gas fees, exchange commissions, and wallet charges added to basis lower future gains dollar for dollar, effectively giving you a deferred deduction.

• Theft losses of digital assets are not deductible at the federal level unless attributable to a federally declared disaster, but some states may still allow them.

How to treat gas and other fees

Fees can:

• Increase your crypto cost basis: when they’re part of acquiring an asset

• Reduce proceeds: when they’re selling/disposing costs

Note: paying fees in crypto can itself be a taxable disposal of the fee token under property principles.

• Costs that are ordinary, necessary, and directly connected to earning crypto income.

• Fees and charges that form part of an asset’s acquisition or disposal cost base.

• Outlays that a bona-fide crypto business incurs in the normal course of operations.

• Schedule C taxpayers (miners, node operators, market-making LLCs).

• C-corps/S-corps/partnerships running crypto activities.

• Investors may adjust basis (not deduct) for certain costs.

• Non-US residents follow local business vs. investment tests.

For investors, most crypto-related “fees” are not deductible separately. Instead, fees generally affect your gain or loss calculation by increasing cost basis for acquisitions or reducing proceeds for dispositions, depending on what the fee relates to.

For crypto businesses, ordinary and necessary expenses tied to earning business income may be deductible on Schedule C (or a business return). Many personal investment expenses are not deductible under current IRS rules.

• Exchange and wallet fees – trading commissions, withdrawal charges (basis adjustment for investors, expense for businesses).

• Crypto tax software and tools – generally deductible when used in a trade or business. For investors, these costs are typically treated as investment expenses and are generally not deductible under current IRS rules.

• Blockchain network (gas) fees – often affect your tax math, but the treatment depends on what the fee was for. Fees tied to acquiring an asset can increase the basis, and fees tied to disposing of an asset can reduce the proceeds. A personal wallet-to-wallet transfer is not itself taxable, but paying gas in crypto can still be a taxable disposal of the crypto used to pay the fee.

• Professional services – legal, bookkeeping, security audits tied to business income.

• Crypto education costs – conferences or courses are deductible only if they maintain or improve skills in an existing crypto business.

Note: For individuals, many investment expenses are “miscellaneous itemized deductions” that are not deductible under current IRS rules.

• Mining expenses – electricity, hosting, ASIC depreciation (MACRS or section 179).

• Office and Internet costs – prorated home-office, cloud servers, VPNs.

• Travel and conference costs – airfare, lodging, per diem for Web3 events.

• Marketing or advertising – fiat or crypto spent promoting a token project or DAO service.

• Personal hardware wallets for long-term HODLing.

• Gas fees on personal transfers between your own wallets (basis carries across, no gain/no loss).

• Personal portion of a home internet bill if you are an investor only.

• Fines or penalties (e.g., late-filing crypto-exchange KYC penalties).

• Hobby-loss mining expenses (if activity lacks a profit motive).
