IRS Form 1099-DA Explained

Informational only — not a substitute for a tax, legal, or investment professional who knows your facts. About the publisher
Form 1099-DA is the IRS information return for digital asset dispositions handled by a broker. If you sold, swapped, or otherwise closed a position through a US reporting platform, you may receive one — the same way stock traders receive a 1099-B. The form is a third-party report. It is not your tax return, it is not always complete on basis, and it is not a list of every coin you still hold in self-custody.
This guide explains what the form is trying to capture, which years the rules phase in, why a transfer can appear without being a sale, and how to sanity-check a real disposal with the crypto capital gains tax calculator. For the ownership test on wallet moves, read is transferring crypto between wallets taxable?.
This is not tax advice. 1099-DA instructions and broker implementations are still maturing. If boxes look impossible, get a CPA who has filed digital-asset returns — not a Discord screenshot.
Why the form exists
For a decade, many crypto users received incomplete 1099-K-style reports, or nothing, while still owing tax on every disposal. Congress required brokers to report digital asset sales so the IRS could match returns the way it matches brokerage 1099-Bs.
The policy goal is ordinary: if a platform sits in the middle of a sale, the IRS wants proceeds (and, eventually, basis) on a standard form. The user goal should be narrower: do not let the form invent a sale that did not happen, and do not hide a sale the form never saw.
That second failure is the self-custody gap. A broker can only report what happened in that account. Coins you withdrew and later sold peer-to-peer or through a non-reporting venue will not appear on that broker’s 1099-DA. You still report them on Form 8949 and Schedule D.
Phase-in: proceeds first, basis later
Digital-asset broker reporting did not appear fully formed.
Gross proceeds. Brokers generally began reporting proceeds for qualifying sales in 2025. That is the year many people will see a 1099-DA that looks “too big” because it lists gross cash or FMV out without a complete basis story.
Basis for covered assets. Additional basis reporting is scheduled to apply for covered digital assets acquired after the applicable start date in that broker account (widely discussed as 2026-forward covered lots). Pre-existing lots and assets that left the platform before the covered period may remain noncovered. Noncovered does not mean nontaxable. It means you supply basis.
If your 1099-DA shows proceeds and a blank or obviously wrong basis, you compute gain yourself. That is normal in year one of any new information-return regime, the same way old stock lots were noncovered on 1099-B for years.
Always read the year printed on the form and the broker’s explanation PDF. Do not assume 2024 folklore still applies.
What a “broker” is (and is not)
A digital asset broker for 1099-DA purposes is, roughly, a party that stands ready to effect sales for customers — centralized exchanges, certain hosted-wallet providers, and other operators that meet the regulatory definition.
Generally not your broker just because you used them:
- A non-custodial software wallet that never takes possession
- A hardware device manufacturer
- A block explorer
If you buy through a partner embedded in an app, that partner may be the reporting broker. The wallet UI and the tax form may not share a brand. Keep trade confirmations.
Hosting vs self-custody is the same split as custodial vs non-custodial wallets: the custodian is the one who can issue a 1099. Self-custody means you are the books.
Boxes you will actually fight with
Implementations vary, but the fights are predictable:
Proceeds. USD (or USD equivalent) from a sale or the FMV of property received in a swap. This should line up with fills, not with account deposits.
Cost basis. Present for covered lots if the broker had it. Missing or $0 for transferred-in coins is common. $0 basis is a red flag, not a gift from the IRS. Using $0 when you have records overstates gain.
Date acquired / date sold. Needed for short-term vs long-term. If the broker did not hold the asset long, they cannot know your original acquire date unless you transferred in with a lot history they accept — most will not.
Gain or loss. If shown, treat it as the broker’s arithmetic, not as a statute. Recalculate.
Transfers in / transfers out. These may appear so the IRS sees movement. A transfer out to a wallet you own is generally not a taxable sale. Paying tax on FMV at withdrawal and then again at a later sale is how people double-tax themselves. Paying nothing on a later self-custody sale because “it was already on the 1099” is how people underreport.
Reconcile transfers with a log: date, txid, quantity, “still me.” Then estimate actual sales in the crypto capital gains calculator.
Income that is not a capital gain. Staking, some rewards, and airdrops can show up in other 1099 series or in platform summaries. Ordinary income at FMV on receipt sets basis. Do not shove rewards into Schedule D as if they were a sale of bitcoin you bought.
Wallet-by-wallet lots vs one big bag
Beginning with 2025 transactions, identification is generally per wallet or account, not one global FIFO pile across every app you have ever used. A 1099-DA is a report from one broker. It cannot apply FIFO to coins that were never in that account.
If you dollar-cost averaged at Exchange A, withdrew, and sold at Exchange B:
- A may report transfers out (and any sales that happened at A)
- B may report sales of lots B thinks you acquired when coins arrived — sometimes using FMV at deposit as if that were basis (wrong if you are the same owner and you have original tickets)
Your job is to use original basis and original acquire date for lots you still own, unless a real disposal reset them. DCA makes this a spreadsheet problem: how crypto dollar-cost averaging works.
If you sell only through a broker, the 1099-DA may be close to complete (especially once covered-basis years arrive). If you hold in self-custody, the form from last year’s exchange is a chapter, not the book. Keep lots when you withdraw; the withdraw is usually not the tax.
How to reconcile in April (without guessing)
- Collect every 1099-DA, 1099-MISC, and platform annual summary. Different products mail different forms.
- Export CSVs from every venue, including withdrawal history, before the UI changes.
- Build a disposal list: sells, swaps, spends. Exclude you-to-you transfers.
- Match 1099-DA proceeds to disposals at that broker. Explain leftovers (transfers, failed trades, duplicates).
- Attach basis from your tickets. Do not accept $0 because the PDF was blank.
- Add missing disposals (DEX, P2P, spending from a personal wallet).
- Check holding period per lot, not per year.
- Watch NIIT and estimates if MAGI is high: NIIT calculator, quarterly estimated taxes.
If step 3 and step 4 cannot be made to agree within a reasonable tolerance, stop filing from memory. That is how amended returns are born.
Tax software that imports 1099-DA will still ask you to confirm transfers. Clicking “accept all” is how transfer FMV becomes phantom sales.
Common mismatch stories
The $80,000 “sale” that was a withdrawal. Broker reports a transfer at FMV. Taxpayer reports $80,000 gain. Coins still sit in a hardware wallet. Later sale reports another gain. Solution: report the transfer as a non-sale and keep basis.
The $0 basis inbound deposit. Coins arrive at Exchange B. B sells them and reports proceeds minus $0. Taxpayer pays tax on 100% of FMV. Original 2021 buys are ignored. Solution: substitute real basis; expect a mismatch letter someday and keep documentation.
The swap that looked like two transfers. BTC leaves, ETH arrives. Economically one disposal of BTC and a new ETH lot. Some UIs list two movements. Report one sale of BTC at FMV of ETH received (plus boot), new ETH basis = FMV.
The harvest that 1099-DA shows and the repurchase it also shows. Crypto tax-loss harvesting is a real sale. Current federal wash-sale rules generally do not treat crypto like stock — but you still report the sale. The repurchase is a new lot. Both may appear.
State returns and the same PDF
States that tax capital gains will want the same character as federal. A transfer that is not a federal sale is usually not a state sale. When you do have a sale, state rates can exceed the federal long-term 15%. Use the state dropdown on the crypto capital gains calculator as a sketch, then your state form.
Canadian taxpayers should not map 1099-DA onto a T1. Use crypto capital gains tax in Canada and CRA slips instead.
What to do if you never get a 1099-DA
You may still have taxable sales. Peer-to-peer, some offshore platforms, and self-custody spends can produce no form. The filing obligation does not depend on mail. Keep your own 8949.
You may get a form for a year you did not sell, because of transfers or rewards. Read it. Do not assume “1099 = I owe.”
Frequently asked questions
Does 1099-DA mean I owe tax on everything listed?
No. It means a broker reported activity. Transfers, errors, and missing basis are common. You report your taxable disposals and income.
If I only transferred to self-custody, do I still receive a form?
You might, showing a transfer. That is not automatically a gain. See wallet transfers.
Can I ignore 1099-DA if I use crypto tax software?
No. Software should ingest the form and your CSVs. Ignoring an IRS information return is how you get underreporter notices. Reconciling is the work.
Will the IRS know about my hardware wallet?
Not from a 1099-DA issued by a wallet that is not a broker. They may know about the withdrawal from the exchange that sent coins there. Later sales from the hardware wallet are still yours to report.
What if two brokers report the same coins?
That can happen around transfers. You still have one economic sale (or none). Document the path so you do not report the same proceeds twice.
Are NFTs on 1099-DA?
Digital assets can include NFTs when a broker effects a sale. Valuation and collectibles rates can differ. Do not assume bitcoin instructions cover a one-of-one JPEG.
Where does this show on the 1040?
Capital gains still flow through Form 8949 and Schedule D (and NIIT Form 8960 if applicable). 1099-DA is the information return that feeds those, the way 1099-B does for stocks.
