Crypto Tax Calculator (2026)

Why crypto tax is not one number on a 1099

Cryptocurrency is property for federal tax purposes—not currency. Every disposition (sale, trade, spend, or sometimes a fork or airdrop) can create a reportable event. The exchange might show proceeds, but your tax depends on cost basis, holding period, and whether income was ordinary at receipt or capital at sale. That gap between platform reports and your actual return is where most crypto filers get surprised.

This calculator helps you model federal tax from the dispositions and income you enter: proceeds minus basis for trades, short-term vs long-term stacking, and ordinary income from mining or rewards. It does not pull blockchain history or verify exchange CSVs—you supply the numbers you believe are correct after reconciling wallets.

Pair it with the capital gains tax calculator for bracket-level capital rate detail and the wash sale calculator when you rebought the same asset within 30 days of a loss.

2026 federal context for crypto

Ordinary income from crypto—mining, some staking, airdrops treated as income—stacks through 2026 brackets (10% through 37%) after your standard deduction: $16,100 single, $32,200 married filing jointly (Rev. Proc. 2025-32). Long-term capital gains use separate rate thresholds that also inflation-adjust; short-term gains do not get those preferential rates.

Net investment income tax at 3.8% may apply when modified AGI exceeds $200,000 single or $250,000 joint. Crypto gains count toward that test when they are net investment income. The calculator surfaces federal income tax layers you enter; NIIT is worth modeling separately if you are near thresholds.

Cost basis methods that change the answer

Specific identification lets you choose which units you sold if you track acquisition dates and amounts precisely. FIFO (first-in, first-out) is the default when you cannot identify lots. Weighted average basis applies in limited circumstances. Using the wrong method can shift thousands of dollars of gain between tax years—especially after years of dollar-cost averaging into one wallet address.

Transferring coins between your own wallets is not a taxable event, but it does not reset holding period or basis. Moving from Coinbase to a hardware wallet is bookkeeping, not a sale. Selling on a decentralized exchange is still a sale even when no 1099 arrives.

How to use this calculator

Step 1 — Separate ordinary income from dispositions

Enter mining, staking, and airdrop income at fair market value when received. That layer is ordinary income in the year of receipt, independent of later price moves.

Step 2 — Enter each sale or trade

For each disposition, record proceeds, cost basis, and acquisition date. The tool classifies short-term vs long-term from holding period and applies the rates you select or that match your filing status.

Step 3 — Net losses and carryforwards

Losses offset gains in the same year first. Net losses up to $3,000 offset ordinary income; excess carries forward. Use the tax loss harvesting calculator for portfolio-level planning across assets.

Worked example (single filer, 2026)

Suppose you sold Bitcoin for $40,000 with $28,000 basis after holding 14 months (long-term), and traded altcoins for a $5,000 short-term gain. You also received $2,000 of staking rewards taxed as ordinary income when paid:

• Long-term capital gain: $12,000
• Short-term capital gain: $5,000 (ordinary rates)
• Ordinary income from staking: $2,000

Taxable income stacks after the $16,100 standard deduction. Long-term gain may face 0%/15%/20% rates depending on total taxable income; short-term gain and staking income sit in ordinary brackets. Run your exact filing status in the form above for cent-level output.

Stablecoins, NFTs, and DeFi

Exchanging crypto for stablecoins is still a disposition—you sold the original token. NFT sales generally follow capital gain rules when the NFT was held as an investment; creators may have ordinary income on primary sales. DeFi liquidity pools, lending, and wrapped tokens can trigger multiple events in one transaction; this calculator does not parse smart-contract logic—you model the net economic result you and your preparer agree on.

Recordkeeping the IRS expects

Keep trade logs, wallet addresses, fair market value at receipt for income events, and notes on forks or airdrops. Form 8949 and Schedule D aggregate dispositions on the return. Starting with tax year 2026, broker reporting on Form 1099-DA will expand, but gaps will remain for self-custody and DeFi—your records still matter.

Estimated tax and withholding

Large crypto gains without withholding can trigger estimated tax requirements and underpayment penalties. If you also have W-2 income, do not assume payroll withholding covers coin profits—use the quarterly estimated tax calculator and the tax refund estimator to see the year-end gap.

State tax

Most states tax crypto gains as capital gains or ordinary income following federal character. A few states have peculiar sourcing rules for traders. Use the state income tax calculator when residency is clear; multi-state remote work adds complexity beyond this page.

Common mistakes

• Treating transfers between personal wallets as sales
• Ignoring income at receipt for staking or mining, then only reporting the eventual sale
• Using current exchange price as basis instead of acquisition cost
• Assuming no report means no tax
• Missing wash sales when repurchasing the same coin within 30 days

Staking, airdrops, and hard forks

Protocol airdrops taxable as ordinary income at receipt when you have dominion and control over tokens—price at receipt hour matters on volatile launch days. Hard forks creating new chains may treat allocated new coins as ordinary income at FMV when recorded on ledger if you have ability to transact.

Mining pools pay gross before pool fees in some 1099 setups—deduct pool fees as expense against mining income. Home mining electricity may be deductible as business expense when mining is trade or business, not hobby; hobby limits deductibility and triggers different NIIT character.

Keep wallet export CSV reconciled to Form 8949 totals before filing—software tax reports often miss DeFi wrapping events you must manual adjust.

Sources and methodology

Federal ordinary brackets and standard deductions follow IRS Rev. Proc. 2025-32. Capital gain rate thresholds are applied from the inputs you provide; this tool does not determine whether a particular token event is ordinary or capital—that is a facts-and-circumstances question for your records and preparer. Results are educational estimates, not tax or legal advice.
