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.

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 permanently disallowed as miscellaneous itemized deductions.

• 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 permanently disallowed as miscellaneous itemized deductions.

• 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, investment expenses are miscellaneous itemized deductions, and those were permanently repealed for tax years beginning after 2025.

• 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). Losses from selling at a loss and repurchasing are a separate question, covered in our guide to wash sale trading in crypto.

The common claim is that crypto theft losses are not deductible unless a federally declared disaster is involved. That is only true for one category of loss.

Section 165(c)(3) covers personal casualty and theft losses, and those are limited to federally or state-declared disasters. However, section 165(c)(2) covers losses from transactions entered into for profit, and that provision survived both the TCJA and the 2025 tax law.

IRS Chief Counsel Advice 202511015, released in March 2025, ran five scam fact patterns through section 165. In three of them, where the taxpayer moved funds intending to invest, the deduction was allowed. In two, a romance scam and a fake ransom demand, it was not. The theft was equally real in all five. What separated them was the taxpayer's purpose at the time the money moved.

What has to be true

• The taking was illegal under the law of the state where it happened

• There was criminal intent

• You transferred the crypto with a profit motive

• There is no reasonable prospect of recovery in the year you claim it

Qualifying losses are reported on Form 4684, Section B, for the year recovery becomes unreasonable rather than the year the funds left your wallet.

Documentation is the whole game

Keep the transfer records, wallet addresses and transaction hashes, your communications with the platform or the scammer, the IC3 complaint, the police report, and any written determination from a bank or exchange about recovery prospects.

Worthless and abandoned crypto is a different question

Do not conflate the two. Losses from crypto that simply became worthless or was abandoned were treated as miscellaneous itemized deductions, and those were permanently repealed for tax years beginning after 2025.

If you were defrauded, get a crypto tax professional to look at the facts. The dollar difference between the two characterizations is large.

Here's a look at how crypto deductions are treated in various countries around the world.

United States

Basis adjustments for investors with capital assets. Schedule C or corporate deductions for active businesses can deduct expenses such as electricity, rent, and software. State rules may differ.

United Kingdom

HMRC allows “allowable costs” (exchange fees, network fees, professional advice) to be added to the acquisition cost when computing Capital Gains Tax. Mining businesses deduct operating expenses against trading profits.

Canada

Transaction fees form part of adjusted cost base. Crypto businesses deduct electricity, rent, and salaries; frequent traders may be classified as carrying on a business.

Australia

CGT cost-base additions include transfer fees and expert advice. Businesses can deduct running expenses under ordinary income rules.

• Track every exchange, wallet, and gas fee; missing basis inflates taxable gains.

• Time large business purchases (e.g., GPU rigs) for section 179 or bonus-depreciation eligibility.

• Use donor-advised funds to contribute appreciated coins and claim a charitable deduction without capital gains recognition. Bunching matters more starting in 2026 because itemizers can deduct contributions only above 0.5% of AGI. One large gift clears that floor once, rather than losing a slice every year.

• Keep separate wallets for business vs. personal holdings to simplify bookkeeping.
