Crypto Capital Gains Tax 2026: Rates, Basis and Filing

U.S. crypto capital gains depend on what was disposed of, its adjusted basis, the units identified and the holding period—not simply the dollars withdrawn from an exchange. Returns filed during 2026 usually report 2025 transactions and use 2025 thresholds; transactions occurring during 2026 generally belong on returns filed in 2027 and use 2026 thresholds. This guide keeps those two years separate and shows how Form 1099-DA fits into the calculation.

Short answer: when does crypto create a capital gain?

The IRS treats a digital asset as property for federal income tax purposes. When an investor sells, exchanges or otherwise disposes of crypto held as a capital asset, the taxpayer generally recognizes a capital gain or loss. The basic formula is:

Capital gain or loss = amount realized − adjusted basis of the units disposed of

The amount realized is generally the U.S.-dollar value received, reduced or adjusted as required for transaction costs. Adjusted basis generally starts with acquisition cost in U.S. dollars, including qualifying acquisition costs, and changes for later adjustments. The cash withdrawn from an exchange is not the formula.

Taxable crypto disposals and non-disposals

A crypto-to-crypto trade is not tax-deferred merely because no dollars touched a bank account. The property given up is valued in U.S. dollars at the transaction time, and the received asset starts a new basis record. Swapping into USDT or USDC likewise can dispose of the outgoing asset.

A bona fide transfer between accounts owned by the same taxpayer generally does not change beneficial ownership. However, a network fee paid in crypto can involve a disposition of the fee units, and transferring an asset to a protocol in exchange for a materially different token can require a separate factual analysis. Labels such as bridge, wrap, deposit or stake are not tax conclusions.

Gifts, charitable contributions, inherited assets, business inventory, section 1256 contracts and personal-use property can follow special rules. This article addresses the common case of an individual investor holding spot digital assets as capital assets.

Crypto capital gains tax rates for 2025 and 2026

The year of the disposition controls the threshold. A return filed in April 2026 generally reports calendar-year 2025 sales. A sale in calendar year 2026 generally appears on the return filed in 2027.

Short-term gains are part of the ordinary-rate calculation. For 2026, the seven individual marginal rates remain 10%, 12%, 22%, 24%, 32%, 35% and 37%. The rate applies through a bracket calculation; it is not a flat rate on every dollar of crypto gain.

Net long-term capital gain is generally subject to preferential 0%, 15% or 20% maximum-rate bands. The relevant taxable-income breakpoints are:

These thresholds measure taxable income and interact with other income and deductions; they are not standalone crypto exemptions. The 3.8% net investment income tax can also apply when modified adjusted gross income exceeds the statutory threshold, commonly $200,000 for single or head-of-household filers and $250,000 for married couples filing jointly. State and local rules are separate.

How to calculate crypto gains with fees

Assume an investor buys 1 ETH for $1,500 and pays a $15 acquisition fee. The initial basis is generally $1,515. Fourteen months later, the investor sells it for gross proceeds of $3,000 and pays a $20 selling fee. If the reporting convention treats the selling cost as reducing amount realized, the calculation is $2,980 minus $1,515, or a $1,465 long-term gain.

Before calculating, confirm whether the exchange's proceeds field is gross or net and whether its exported basis already includes fees. Adding or subtracting the same fee twice is a common error. A fee paid in a separate crypto asset also needs its own lot and disposition analysis.

Every taxable line should preserve:

• asset and quantity disposed of;
• acquisition date and disposition date;
• U.S.-dollar proceeds and pricing source;
• identified tax lot and adjusted basis;
• fees and how each was treated;
• exchange, wallet, transaction ID and source record;
• any Form 8949 adjustment and supporting explanation.

Short-term versus long-term holding period

Under IRS Publication 544, property held for one year or less generally produces short-term gain or loss; property held for more than one year generally produces long-term gain or loss. Counting starts on the day after acquisition, and the disposition day is included. “Twelve months” is not always the same as “more than one year.”

Each tax lot has its own holding period. Moving units to another wallet owned by the taxpayer generally should not reset the original acquisition date. Reward units normally begin a separate holding period after receipt. Gifts and inheritances can have special carryover or deemed holding-period rules.

Do not infer an acquisition date from the date an inbound transfer reached the selling exchange. Trace the lot back to the original purchase, income event, gift or other acquisition.

FIFO, specific identification and wallet-level basis

When a taxpayer owns multiple units of the same digital asset, the units sold must be identified under the applicable rules. Beginning in 2025, the final digital-asset regulations generally apply specific-identification or default rules within the wallet or account holding the units; an unrestricted universal pool across every wallet is no longer the operative framework. See the IRS digital-assets overview and Revenue Procedure 2024-28.

Adequate identification has timing and record requirements. For eligible 2025 broker-held transactions, Notice 2025-7 provides temporary relief that can allow a documented standing order in the taxpayer's books and records if entered before the sale. It does not authorize choosing HIFO retrospectively after seeing the year's result.

If valid identification is absent, the applicable default rule determines the units. Maintain the asset quantity, acquisition date and basis for each wallet, and document transfers so unused basis follows the correct units.

How crypto capital losses offset gains

Capital losses first participate in the Schedule D netting process: short-term and long-term groups are computed separately, then combined under the ordering rules. If an individual's net capital loss exceeds capital gains, the annual deduction against other income is generally limited to $3,000, or $1,500 for married filing separately. Unused amounts generally carry forward, subject to the rules.

A market decline without a sale or other recognized event is usually an unrealized loss, not a deductible capital loss. Losing access to keys, an exchange failure, theft, abandonment, worthlessness and a claim in bankruptcy are not automatically equivalent to selling a capital asset. Each requires its own legal and factual analysis.

The wash-sale rule in section 1091 applies to stock or securities. Many spot digital assets may fall outside that wording, but classification, related-party rules, straddles, economic substance and future law can change the result. An article should not promise that every immediate crypto repurchase is safe.

Form 1099-DA, Form 8949 and Schedule D

For 2025 dispositions, applicable digital-asset brokers begin reporting gross proceeds on Form 1099-DA. Broker basis reporting is phased in later for applicable covered assets, so a 2025 form can show proceeds without basis. Missing broker basis does not mean the taxpayer's basis is zero; it means records must be reconstructed.

The 2025 Form 8949 instructions add digital-asset categories G, H and I for short-term transactions and J, K and L for long-term transactions. The category depends on whether the transaction and basis were reported to the IRS. Form 8949 reconciles broker-reported proceeds and taxpayer basis, while Schedule D performs the capital gain and loss netting.

1. Import every exchange, wallet and on-chain source.
2. Reconcile own transfers and remove duplicate imports.
3. Match Form 1099-DA proceeds to dispositions.
4. Reconstruct basis and acquisition dates for transferred units.
5. Apply valid lot identification within each wallet or account.
6. Classify short- and long-term results and prepare Form 8949.
7. Complete Schedule D and retain the reconciliation.

Responsible crypto capital-gains planning

• Review holding periods: compare the tax effect of a sale now with a later date, without ignoring market risk.
• Use losses deliberately: identify genuine disposals and model Schedule D netting and carryovers.
• Record tax lots before sale: use adequate identification rather than a year-end reconstruction designed only for the lowest tax.
• Donate carefully: a direct contribution of appreciated property can have benefits, but qualified organization, appraisal, substantiation and deduction-limit rules apply.
• Estimate federal and state payments: a profitable trade does not automatically trigger withholding.
• Keep reserves: reinvesting all proceeds can leave no cash for tax.

Use the U.S. filing workflow with the Form 1099-DA guide. A CoinTaxReporting tax report can retain missing-basis review items, and sample reports show the expected audit trail.
