2026 Crypto Tax Calculator

The IRS generally treats digital assets as property, so general property-tax principles apply. For a digital asset held as a capital asset, gain or loss starts with amount realized minus adjusted basis.

This calculator evaluates each submitted disposition, preserves a negative loss, and aggregates the signed results only after assigning short-term or long-term character from calendar dates.

Selling a digital asset for U.S. dollars can create a taxable capital gain or loss even when no cash is withdrawn from an exchange account. The sale is measured in U.S. dollars at the transaction time.

A Form 1099-DA is not what creates the tax event. Taxable transactions generally must be reported whether or not a broker furnishes an information return.

Exchanging one digital asset for a materially different digital asset can be a disposition of the asset transferred. The USD fair market value received helps determine amount realized and gain or loss.

Enter the USD value at the time of the exchange. This calculator does not fetch a market price or decide which units were disposed.

Paying for goods or services with a digital asset can dispose of that asset. A capital gain or loss may arise from the difference between the value received and adjusted basis.

Enter the USD fair market value of the goods or services received and any allocable disposition costs; do not enter the original purchase price of the goods as crypto basis.

Gross proceeds apply naturally to a cash sale. For an exchange or spending transaction, the comparable input is the USD fair market value of the digital assets, other property, goods, or services received.

The calculator defines amount realized as entered gross proceeds or fair market value minus disposition fees. Amount realized can be negative when fees exceed value received.

Allocable transaction costs such as commissions and certain network fees can reduce amount realized on a disposition. This model subtracts the separately entered disposition fee before adjusted basis.

It does not decide whether a fee is allocable, value a fee paid in another digital asset, or model the separate disposition that can occur when digital assets are used to pay fees.

Adjusted basis is the tax basis of the units disposed after required increases or decreases. It can depend on acquisition cost, transaction costs, prior income inclusion, and later adjustments.

You must determine and enter adjusted basis. TaxArith does not reconstruct it from exchange history or verify that a broker-reported amount is complete.

When units of the same digital asset were acquired at different times or prices, the identified units can change both adjusted basis and holding period. Records and applicable identification rules therefore matter.

This calculator does not choose FIFO, LIFO, HIFO, Specific Identification, or any other lot method. Enter one row for each disposition grouping whose dates and basis you have already determined.

A digital asset held for one year or less is generally short-term; more than one year is generally long-term. The holding period ordinarily begins the day after acquisition and ends on the disposition date.

TaxArith compares calendar dates without local-time conversion. It does not apply inherited-property, gift carryover, partnership-interest, or other special holding-period exceptions.

Final net short-term capital gain is added to ordinary taxable income. It is not assigned a flat 15% crypto rate.

The shared progressive 2026 federal brackets calculate the full scenario, so a short-term gain can pass through more than one ordinary bracket.

Eligible final net long-term gain is stacked above ordinary taxable income. Portions can fall in the 0%, 15%, and 20% ranges based on total taxable income rather than the size of the gain alone.

The result isolates the allocation of the final modeled net long-term gain after all crypto activity, other capital activity, carryovers, and cross-netting. It is not a rate quoted for an individual trade.

Qualified dividends share the same 0%, 15%, and 20% preferential ranges as ordinary net long-term capital gain. They do not participate in capital gain/loss netting.

For the displayed gain allocation, qualified dividends occupy available preferential space before the final net long-term gain. This can push more gain into a higher band.

Crypto capital results are not taxed in isolation from stock sales or other capital activity. Current short-term amounts net together, and current long-term amounts net together, before cross-netting.

Use the other-capital fields only for activity not already represented by the crypto rows. Entering the same disposition twice overstates the modeled result.

Prior-year short-term and long-term capital loss carryovers retain their character. This calculator subtracts each positive entered amount within its category before cross-netting.

Carryovers are present in both baseline and with-crypto scenarios. The displayed impact therefore isolates the difference produced by submitted crypto dispositions in the supplied context.

For Single, Married Filing Jointly, and Head of Household, a remaining modeled net capital loss can reduce ordinary taxable income by up to $3,000. The deduction cannot exceed the net loss or available ordinary taxable income.

This is an income deduction, not a $3,000 credit. Loss used against capital gains during netting does not also become part of the ordinary-income deduction.

Married Filing Separately uses a $1,500 annual capital-loss deduction limit in this model. The same net-loss and ordinary-income constraints continue to apply.

Changing filing status affects this limit as well as the ordinary and preferential federal thresholds, but displayed results change only after a new valid Calculate submission.

A loss may offset a capital gain already present in the baseline, support a limited ordinary-income deduction, or remain unused. Once the current deduction is limited, an additional loss can change only the estimated unused amount.

In that situation, tax with and without the entered crypto dispositions can be equal, producing a $0.00 estimated current federal income-tax impact.

Moving a digital asset between wallets or accounts that you own or control generally is not itself a disposition. It should not be entered as a taxable sale merely because an exchange records a transfer.

Paying a transfer fee with digital assets can have separate consequences, and determining wallet ownership is outside this calculator.

Receiving digital assets as wages, contractor compensation, mining or staking rewards, an airdrop, or other income can require an income inclusion. A later sale or exchange is a separate disposition event measured from adjusted basis.

This calculator models only the later disposition of a digital asset held as a capital asset. It does not calculate the original crypto income or self-employment tax.

Form 1099-DA can report digital-asset proceeds and, for some covered assets, basis information. Capital dispositions may also require Form 8949 and Schedule D treatment under their instructions.

TaxArith does not reconcile Form 1099-DA, apply Form 8949 adjustment codes, prepare Schedule D, or file a federal return. Reporting duties can exist even without a broker form.

An exchange may lack acquisition information for transferred-in assets, report a noncovered asset, or omit adjustments known only to the taxpayer. Gross proceeds alone do not establish taxable gain.

Reconcile wallet records, exchange records, and information returns to determine the correct units, dates, fair market value, and adjusted basis before relying on an estimate.

The model excludes mining, staking, airdrops, forks, compensation, business inventory, NFTs subject to collectibles rules, gifts, donations, inheritance, worthless assets, loans, liquidation, margin, derivatives, futures, options, and perpetual contracts.

It also excludes wash-sale adjustments, Section 1250 gain, depreciation recapture, the home-sale rules, AMT, kiddie tax, foreign reporting, state and local tax, and tax-lot optimization.

The 3.8% Net Investment Income Tax can apply separately based on modified adjusted gross income, net investment income, and Form 8960 rules. Regular capital-gains tax does not replace NIIT.

NIIT is intentionally excluded from this calculator's tax impact. The Capital Gains Tax Calculator can provide a separate entered NIIT estimate, but neither tool prepares Form 8960.

The 2026 federal income-tax and long-term capital-gains thresholds were verified on August 11, 2026 using IRS Revenue Procedure 2025-32 as published in Internal Revenue Bulletin 2025-45. General digital-asset property, basis, fair-market-value, disposition, holding-period, gain-and-loss, carryover, and reporting rules were reviewed using the IRS Digital Assets guidance, IRS digital-asset transaction FAQs, Topic No. 409, Publication 550, the Instructions for Form 8949, and IRS Form 1099-DA guidance.

Tax rules and forms can change. The result remains an estimate based only on submitted inputs and the limited federal individual capital-asset model described here.
