Form 1099-DA Arrives in 2026: A Crypto Investor's Guide to the IRS's First Digital Asset Reporting Form

Open your inbox in late January 2026 and you may find something that has never existed before: a Form 1099-DA from your crypto exchange. For more than a decade, the IRS has had to take taxpayers' word for what they bought, sold, and earned on-chain. That era is officially over. Beginning with sales effected after December 31, 2024, U.S. digital asset brokers must report transactions to the IRS on a brand-new information return — and the rules ramp up sharply for sales that happen after January 1, 2026.

If you trade on Coinbase, Kraken, Gemini, a payment processor, or any U.S. hosted wallet provider, the form is coming. The question is whether your records agree with the broker's. They very often will not. This guide walks through what Form 1099-DA actually is, what it reports (and what it conspicuously does not), the two-stage rollout that determines whether your basis is on the form or still your problem, and the practical steps to take before the first wave of forms hits.

Why Form 1099-DA Exists

Stock brokers have issued Form 1099-B to the IRS since the 1980s. Crypto, despite being treated as property since 2014, sat in a reporting blind spot. Some exchanges issued 1099-MISC for staking, others sent 1099-K for gross volume, and many sent nothing at all. Taxpayers were left to track lots, calculate basis, and self-report — which they did, badly. The Treasury Inspector General has repeatedly called the resulting tax gap one of the largest unmonitored sources of underreporting in the code.

The Infrastructure Investment and Jobs Act of 2021 directed Treasury to fix that. Final regulations published in 2024 created Form 1099-DA — Digital Asset Proceeds From Broker Transactions — and set a two-step phase-in. The first forms cover 2025 sales (gross proceeds only) and arrive in early 2026. The 2026 sales year adds mandatory cost basis reporting, and those forms arrive in early 2027.

Who Is a "Broker" Under the New Rules

The regulations define a digital asset broker as "any person who, in the ordinary course of a trade or business, stands ready to effect sales of digital assets to be made by others." In practice, that means:

• Centralized exchanges and trading platforms (Coinbase, Kraken, Gemini, Binance.US)
• Hosted wallet providers that custody customer keys
• Crypto payment processors handling merchant transactions
• Some kiosk and ATM operators

What is not a broker, after a high-profile 2025 reversal:

• Decentralized exchanges (Uniswap, Curve, dYdX)
• Self-custody wallets (MetaMask, Ledger, Trezor)
• Smart contract front-ends and DeFi aggregators

A 2024 Treasury rule briefly swept DeFi front-ends into the broker definition. Congress revoked that expansion under the Congressional Review Act in early 2025, leaving the noncustodial corner of the ecosystem outside the 1099-DA regime — for now. Anyone moving assets between centralized brokers and self-custody should expect mismatches as a result.

The Two-Stage Rollout: Why 2025 and 2026 Look Different

Read every 1099-DA you receive carefully, because the form changes meaningfully between its first and second year.

2025 Sales (Forms Arriving Early 2026)

Brokers must report:

• Gross proceeds (net of transaction costs)
• Identification of the digital asset and units sold
• Disposition date

Brokers are not required to report cost basis or acquisition date for 2025 sales. Box 9 — "noncovered security" — will be checked on essentially every form. You are still on the hook for calculating gain or loss yourself.

2026 Sales (Forms Arriving Early 2027)

This is the bigger shift. For digital assets acquired after January 1, 2026, in a custodial broker account, the broker must report:

• Acquisition date and cost basis
• Holding period (short-term vs. long-term)
• Wash sale loss disallowance (when applicable)
• Accrued market discount

These are "covered securities." Anything you held before 2026, or anything you transferred in from another wallet without proper basis documentation, remains a noncovered security — even after 2026. Brokers must check Box 9 for those, and you are once again responsible for proving basis.

What the Form Actually Reports — Box by Box

Knowing what each box means turns the form from a panic-inducing letter into a workable summary. The most important fields:

• Box 1a–1d: Asset code, units sold, disposition date, and gross proceeds.
• Box 1e–1g: Cost basis, acquisition date, and holding period (covered securities only).
• Box 1i: Nondeductible wash sale loss. This applies only if the digital asset is treated as a security for tax purposes — currently a narrow set of tokenized securities. Most crypto is property, and Section 1091 wash sale rules do not yet reach it.
• Box 9: Noncovered security indicator. When checked, the broker is not vouching for basis.
• Box 11a–11d: Reporting method (FIFO, specific identification, etc.) and any aggregation indicator.
• Box 12a–12b: Units and date of transfers into the account. This is how the IRS will eventually link wallet-to-wallet movement.

Brokers use special box codes — including new aggregate methods — for qualifying stablecoins (a $10,000 de minimis aggregation threshold) and specified NFTs (a $600 de minimis threshold). Routine stablecoin activity may show up as a single annual line rather than thousands of swaps. Rewards, staking income, airdrops, and hard forks are excluded from 1099-DA entirely; they continue to flow through 1099-MISC or remain self-reported.

Where Mismatches Will Come From

The IRS will receive its copy of every 1099-DA at the same time you do, and its automated underreporter system will compare the form to what you put on Form 8949 and Schedule D. Expect notices when these common discrepancies appear:

1. Pre-2026 holdings sold in 2026. The broker reports zero basis (Box 9 checked). Your software shows a hefty basis. The IRS sees what looks like 100% gain.
2. Wallet transfers. You moved 2 ETH from MetaMask to Coinbase, then sold. Coinbase has no acquisition history; it can only fill in the transfer-in box and treat the asset as noncovered. Your basis calculation must follow the asset across wallets.
3. Stablecoin aggregation. Your form shows one $42,000 USDC line. Your records show 1,400 individual conversions. Both can be correct; reconciliation requires matching the aggregate, not each line.
4. Lot identification mismatches. Brokers default to FIFO unless you opted into specific identification before the sale, with adequate written instructions. Tax software that retroactively assumes HIFO or LIFO will conflict with the 1099-DA.
5. Bridges, swaps, and wrapping. Wrapping ETH into wETH, bridging to L2s, or routing through a centralized swap can each trigger or omit a 1099-DA depending on who actually held the asset at the moment of disposition.

Specific Identification: Now or Never

Specific identification — choosing exactly which tax lots to sell — is one of the most powerful crypto tax planning tools, and the new rules make timing critical. To use specific ID for a covered security, you must instruct the broker by the date the sale settles, in adequate detail (typically the acquisition date and basis of the lot you want to sell). After settlement, FIFO controls. Once a 1099-DA is issued under FIFO, retroactively reclassifying lots in your own software creates exactly the kind of mismatch the IRS automated systems are designed to flag.

Practical takeaway: configure your exchange settings before you place sell orders, not at year-end.

Filing Mechanics and Deadlines

For brokers, 1099-DA is due to recipients by February 15 of the year following the sale (the same later deadline that already applies to 1099-B), and to the IRS by March 31 if filed electronically. Penalties under sections 6721 and 6722 apply to incorrect or missing forms — generally $60 to $310 per form depending on lateness, with intentional disregard penalties starting at $630 per form with no cap.

For taxpayers, the new form does not change where you report. Crypto gains and losses still flow through:

• Form 8949 — every disposition, with proceeds and basis. New boxes G, H, and I now apply to short-term digital asset transactions; box C is no longer correct for crypto. Long-term transactions use boxes J, K, and L.
• Schedule D — totals roll up here.
• Schedule 1 — for ordinary income items like staking and rewards (not on 1099-DA).
• Form 1040 — the digital asset question at the top still requires a yes/no.

Box 9 noncovered transactions go on Form 8949 with code "B" in column (f) when basis was reported but you adjust it, or with the appropriate code when basis was missing entirely.

Recordkeeping the Form Cannot Replace

Even after 2026 transactions get full basis reporting, your own records remain the source of truth for several common situations:

• Pre-2026 acquisitions — basis follows the coin forever, but no broker will compute it for you.
• Self-custody activity — every DeFi swap, LP deposit, NFT mint, and bridge is invisible to the 1099-DA system but visible on-chain to the IRS. Keep transaction hashes, dates, and USD values at the time of each event.
• Cost basis methods — FIFO, HIFO, specific ID; each must be applied consistently and documented.
• Lost or stolen assets — the broker will not know.
• Forks, airdrops, staking, mining, and play-to-earn — these are ordinary income at fair market value on receipt and create new basis.

Solid bookkeeping from day one is what turns a 1099-DA from a stress test into a one-page reconciliation. Treat it the way a stock investor treats a 1099-B: a starting point, not the final answer.

Practical Steps to Take Before the First Form Arrives

1. Download a complete transaction history from every centralized exchange, hosted wallet, and payment processor you have used since you started in crypto. APIs and CSV exports become harder to access once accounts go dormant.
2. Reconcile pre-2026 lots now. Identify what you held on January 1, 2026, and compute basis for each lot. Anything you sell in 2026 from those holdings will arrive on a 1099-DA as noncovered, and you will need that work in front of you.
3. Pick a cost basis method and document it. If you intend to use specific identification, configure exchange settings and start logging instructions before each sale.
4. Map every wallet transfer. Outgoing transfers from a broker leave the asset's basis with you; incoming transfers reset the broker's clock. A simple spreadsheet of date, amount, sending wallet, and receiving wallet pays for itself the first time the IRS asks.
5. Audit your self-custody and DeFi activity. Even though no 1099-DA will issue for it, the IRS still expects every disposition on Form 8949. Pull the on-chain history while you are at it.
6. Plan for 1099-DA matching. Once forms arrive, compare each line to your records. Open a dispute with the broker within weeks, not months — corrected forms are far easier to obtain in February than in October.

A Note on the Wash Sale Loss Question

Box 1i on the new form references wash sale loss disallowance, and the bare presence of that box has caused widespread confusion. Internal Revenue Code Section 1091 disallows losses only on sales of "stock or securities." The IRS has consistently classified most digital assets as property, not securities, so the wash sale rule generally does not apply. You can sell BTC at a loss, repurchase the same day, and still claim the loss — for now.

The exception is digital assets that are also stock or securities for tax purposes, such as tokenized equity in a registered company. Those go in Box 1i. Most retail crypto investors will see this box blank year after year. Congress has repeatedly proposed extending the wash sale rule to digital assets; if and when that happens, the form is already built to enforce it.

Keep Your Crypto Records Audit-Ready From Day One

The arrival of Form 1099-DA shifts the burden of proof in a subtle but important way: the IRS now has its own copy of what your broker says you did. Whether your return matches comes down to the quality of records you have been keeping all along. That is exactly the case for plain-text accounting. Beancount.io gives you a transparent, version-controlled ledger where every transaction, lot, and cost basis decision is auditable in human-readable text — no black-box export, no vendor lock-in, no surprises when the 1099-DA shows up.
