How to Report Crypto on Your US Tax Return (2026)

What changed for 2026: Form 1099-DA goes live

Starting January 1, 2025, US-based crypto brokers — Coinbase, Kraken, Gemini, and most centralized exchanges — were required to begin tracking and reporting customer dispositions on the new Form 1099-DA. The first 1099-DAs covering 2025 activity will land in early 2026, and by tax year 2026 the system is fully operational.

This matters for two reasons. First, the IRS now has matched data. If you do not report what your broker reported, expect a CP2000 notice 12 to 18 months later. Second, the broker's basis tracking only works going forward — for coins moved between exchanges, transferred to self-custody, or acquired before 2025, the basis number on your 1099-DA is often wrong or missing.

A clean 2026 crypto return reconciles broker-reported figures against your own records, corrects basis where necessary, and documents every adjustment so it survives an IRS inquiry.

The four taxable events every crypto holder must track

US tax law treats cryptocurrency as property, not currency. That means every disposition is potentially a taxable event. There are four common categories you must track separately:

• Sale for fiat (USD): straightforward capital gain or loss based on proceeds minus basis.
• Crypto-to-crypto trade: a deemed sale of the first asset at fair market value, plus a new acquisition of the second. Every swap on Uniswap or PancakeSwap is two events.
• Spending crypto on goods or services: also a deemed sale at fair market value.
• Receiving crypto as income: staking rewards, mining, airdrops, hard forks, and payment for services are ordinary income at fair market value on the date received — and the receipt establishes the new basis going forward.

Form 8949 and Schedule D: how the numbers actually flow

Capital gains from crypto are reported on Form 8949, then summarized on Schedule D. Each transaction needs five fields: description, date acquired, date sold, proceeds, and cost basis. Short-term (held one year or less) and long-term (held more than one year) are reported in separate sections at different tax rates.

If you have hundreds or thousands of trades, you do not need to type each one. The IRS accepts a summary line on Form 8949 plus an attached statement (PDF or CSV) listing each transaction. Most professional crypto tax software (CoinTracker, Koinly, TaxBit, ZenLedger, CoinLedger) produces this statement in IRS-acceptable format.

Ordinary income from staking, airdrops, mining, and rewards goes on Schedule 1, line 8v as 'Digital assets received as ordinary income not reported elsewhere.' Self-employment crypto income (mining as a trade or business, validator-node operations) goes on Schedule C and is subject to self-employment tax.

DeFi: the part the IRS has not fully clarified, and what to do anyway

Decentralized finance is the messiest area of crypto tax. Liquidity provision, yield farming, lending protocols, and rebasing tokens all raise questions the IRS has not formally answered. In the absence of clear guidance, a defensible position is to apply the existing property and barter rules consistently:

• Adding to a liquidity pool: most CPAs treat this as a disposition of the deposited tokens for LP tokens, triggering a taxable event. Removing liquidity reverses it.
• Lending (Aave, Compound, Maker): deposit and withdrawal of the same asset is generally not taxable; interest received is ordinary income.
• Yield farming rewards: ordinary income at fair market value when received and claimable.
• Wrapping (ETH to wETH): conservative position is taxable, more aggressive position treats it as a non-event. Pick a methodology and apply it consistently.
• Rebasing tokens: treat each rebase as ordinary income at fair market value, with new basis for the rebase amount.

NFTs: collectibles rate and the hidden royalty problem

NFTs held more than one year and determined to be 'collectibles' under IRC Section 408(m) are taxed at a maximum 28% long-term rate, not the standard 20%. The IRS has indicated most art and profile-picture NFTs likely qualify as collectibles.

Selling an NFT is a capital gain transaction reported on Form 8949. Creating and selling NFTs as an artist is ordinary income on Schedule C, subject to self-employment tax. Royalties received from secondary sales are also ordinary income.

Where it gets complicated: gas fees paid to mint or transfer an NFT generally adjust basis (mint cost) or are a selling expense (transfer cost). They are not separately deductible.

Wallet-to-wallet transfers: not taxable, but you must track them

Moving Bitcoin from your Coinbase account to your Ledger hardware wallet is not a taxable event. It is the same coin in your own hands. The problem is that your exchange may report the outbound transfer as a sale on the 1099-DA, and your hardware wallet has no idea what your basis was.

Without explicit tagging, professional crypto tax software will often treat unreconciled transfers as sales (proceeds with zero basis = maximum tax) or acquisitions (zero basis going forward = maximum tax on future sale). Both are wrong.

The fix is to import every wallet and exchange into a single software environment, then tag matched transfers so they net to zero. This is the single most important hour of work in any crypto reconciliation — and the part most DIY filers skip.

Fixing prior years: when to amend and when to use the streamlined filing

If your 2021–2024 returns omitted crypto income or miscalculated gains, you have options. For an isolated error, an amended return (Form 1040-X) is the standard path. For a pattern of unreported foreign-exchange crypto with FBAR implications, the IRS Streamlined Domestic Offshore Procedures may apply.

The window matters. The general statute of limitations is three years, but six years for understatements of more than 25% of gross income, and unlimited for fraud. If you have years of unreported crypto, doing nothing is the worst option — the IRS now has the data and works backwards from the most recent year.

For high-volume traders or significant prior-year gaps, a CPA-led reconciliation across exchanges and wallets is usually faster and cheaper than trying to retrofit consumer software around a multi-year mess.

How Side Growth Partners handles a crypto tax engagement

Every crypto engagement starts with an exchange and wallet inventory: Coinbase, Kraken, Gemini, Binance.US, every self-custody wallet, every DeFi protocol address. We pull CSVs or use read-only API keys, load everything into professional reconciliation software, and reconcile transfers between your own wallets so they do not become phantom sales.

From there we apply your preferred cost basis methodology (specific identification when it saves you money, FIFO when it does not), separate ordinary income from capital, and produce a single clean Form 8949 plus a Schedule 1 income figure. We document every methodology decision in a workpaper so the position is defensible if the IRS asks.

We work with crypto clients nationwide from our Boston office. If you have a messy crypto year, a CP2000 notice, or several prior years that need to be cleaned up at once, book a 15-minute scoping call and we will quote the engagement after we see the shape of the data.
