Web3 Tax Guide: What Crypto and Blockchain Startups Need to Know in 2026

The IRS treats digital assets as property, not currency, under Notice 2014-21. That covers utility and governance tokens, NFTs and stablecoins. Every sale, exchange, or use of a digital asset as payment is a disposition, and you compute gain or loss from basis and holding period.

For a web3 startup that turns into a bookkeeping problem fast, because on-chain activity can mean thousands of dispositions a month. A few other baseline rules:

• Revenue Ruling 2019-24: a hard fork followed by an airdrop of new tokens creates ordinary income at fair market value when you gain dominion and control of them.
• Revenue Ruling 2023-14: staking rewards are income when received (more below).
• Protocol fees, liquidity pool revenue and validator rewards are generally ordinary income at fair market value on the date received.

Track each inflow in US dollars at the time of receipt. That value becomes your basis when the token is later sold.

Custodial crypto brokers now report customer transactions to the IRS on Form 1099-DA under final regulations issued in July 2024 (T.D. 10000). The rollout is phased:

• Gross proceeds: brokers report gross proceeds for sales on or after January 1, 2025. Those first forms went out in early 2026.
• Cost basis: brokers report basis for covered securities, meaning digital assets acquired on or after January 1, 2026 and held in a custodial account with that broker until sale.
• De minimis options: brokers may skip reporting qualifying stablecoin sales if a customer's annual gross proceeds are $10,000 or less, and specified NFT sales if they are $600 or less.

The DeFi broker rule is gone. In December 2024 the IRS finalized a separate rule that would have treated certain decentralized, non-custodial front-end services as brokers. Congress disapproved that rule under the Congressional Review Act (H.J.Res. 25), signed April 10, 2025 as Public Law 119-5. Non-custodial DeFi protocols therefore do not have 1099-DA obligations under current rules.

For a startup this matters in two ways. If you run a custodial platform, you may be a broker with a reporting obligation. If your treasury trades on exchanges, expect 1099-DAs that show proceeds without basis for older lots, so your own records still decide the gain.

How a token launch is taxed depends on its structure, and there is still no comprehensive IRS guidance on token issuance.

Tokens sold for cash or crypto in a public or private sale are commonly treated as income to the issuing entity, though some issuers take other positions depending on the token's rights. A SAFT (Simple Agreement for Future Tokens) is often analyzed like a prepaid forward contract, with income deferred until delivery. The IRS has not ruled on SAFTs, so treat both positions as areas of real audit risk and document the analysis.

Tokens the company mints and keeps in its treasury are generally not taxable at issuance. Each later sale, distribution or use of treasury tokens for compensation is a taxable event.

Keep a token ledger that records:

• Issuance date and quantity
• Treasury balance by wallet
• Date, quantity and purpose of each disposition
• Fair market value at each disposition

Pick one pricing method and use it consistently, for example a volume-weighted average price from a major exchange at a fixed time of day.

Revenue Ruling 2023-14 holds that a cash-method taxpayer who stakes tokens native to a proof-of-stake blockchain includes the rewards in gross income at fair market value when the taxpayer gains dominion and control over them. The ruling applies the same answer when the staking happens through a cryptocurrency exchange.

Other DeFi income does not map neatly onto traditional categories, and the IRS has said little:

• AMM fees paid to a protocol treasury are generally ordinary income when received.
• Lending interest is ordinary income; accrual-basis companies recognize it as it accrues.
• Impermanent loss is not a deductible loss on its own. Gain or loss is recognized when you exit the position.
• Depositing assets into a liquidity pool in exchange for LP tokens may itself be a disposition. Practitioners disagree, so pick a position and apply it consistently.

If a DAO operates through a legal entity wrapper, the entity reports revenue that flows to its treasury or controlled wallets.

Paying people in crypto creates the same tax obligations as paying them in dollars, measured at fair market value when paid.

For employees, wages paid in crypto are subject to federal income tax withholding, FICA and FUTA, and are reported in US dollars on Form W-2. You need cash on hand to remit the withholding, since the IRS does not accept tokens.

For contractors, report payments on Form 1099-NEC. The reporting threshold was $600 for payments made in 2025 and rises to $2,000 for payments made after December 31, 2025, under the One Big Beautiful Bill Act (P.L. 119-21).

Token grants follow the stock compensation framework of IRC §83 and, for deferred arrangements, §409A. With vesting tokens, the recipient recognizes ordinary income at vesting equal to fair market value then, unless they file an 83(b) election within 30 days after the tokens are transferred. That window has no extension.

If you pay in crypto regularly, use a payroll provider that supports digital asset compensation and handles the dollar conversion and withholding.

If you accept payments through a third-party settlement organization, such as a card processor or payment app, you may receive Form 1099-K. The One Big Beautiful Bill Act retroactively restored the original threshold: a 1099-K is required only when payments exceed $20,000 and there are more than 200 transactions in the year. The lower thresholds the IRS had been phasing in no longer apply.

Form 1099-K and Form 1099-DA can both show up for the same business. Reconcile both against your books rather than assuming either form is complete.

A web3 startup needs three layers of financial records:

1. On-chain data: wallet and transaction monitoring across every chain you use.
2. A crypto subledger (tools such as Bitwave, Cryptio or TRES Finance) that classifies on-chain activity, tracks lots and basis, and posts summarized entries to the general ledger.
3. A general ledger (QuickBooks, Xero or NetSuite) for off-chain expenses, payroll and consolidated reporting.

Reconcile wallet balances monthly, close token treasury activity on the same calendar as the rest of the books, and keep fair value support for every receipt. When 1099-DAs arrive, compare them to your subledger lot by lot.

We set up and reconcile these layers for web3 startups and prepare returns that apply the crypto-specific rules above. Guidance in this area is still developing; this article reflects IRS and congressional sources checked in October 2026 and is not tax advice for your specific facts.
