The 1099-DA Timeline: What Changed and When
The road to 1099-DA took years. Here's the timeline that matters:
2021-2023: Infrastructure Investment and Jobs Act passed, requiring "brokers" to report digital asset transactions. IRS began drafting regulations.
2024: Final regulations published. Form 1099-DA finalized. Brokers began preparing systems.
2025 tax year (forms issued Jan-Feb 2026): First mandatory 1099-DA reporting. Brokers must report gross proceeds. Cost basis reporting NOT yet required.
2026 tax year (forms issued Jan-Feb 2027): Brokers must report BOTH proceeds AND cost basis for covered securities.
If you're reading this in early 2026, you're dealing with the first wave of mandatory 1099-DAs. These forms report what you sold, but not (yet) what you paid for it.
Who Issues 1099-DA and Who Doesn't
Understanding who must issue these forms prevents confusion about missing paperwork.
Entities Required to Issue 1099-DA
Custodial Exchanges: Coinbase, Kraken, Gemini, Crypto.com, Binance.US, Robinhood, and similar platforms where you create an account and they hold your assets.
Hosted Wallet Services: Any service that maintains custody of your private keys while you access through their interface.
Digital Asset Kiosks: Bitcoin ATMs and physical crypto purchase locations.
Certain Payment Processors: Services like BitPay when they hold assets on your behalf before converting to fiat.
Stablecoin Redemptions: When you redeem USDC directly through Circle or similar issuers.
Entities NOT Required to Issue 1099-DA (Yet)
Decentralized Exchanges: Uniswap, SushiSwap, Curve, 1inch, and other DEXs where you interact directly via wallet.
Non-Custodial Wallets: MetaMask, Ledger, Trezor, Phantom, and similar self-custody solutions.
Validators and Miners: Staking and mining rewards don't trigger 1099-DA (though they're still taxable income).
Peer-to-Peer Transactions: Direct wallet-to-wallet transfers between individuals.
The IRS is developing separate rules for decentralized platforms. For now, these transactions remain your responsibility to track and report—1099-DA or not.
Understanding Every Box on Form 1099-DA
The form contains more information than most people realize. Here's what each section means:
| Box | Name | What It Contains | Notes |
|---|---|---|---|
| Header | Filer Information | Broker's name, address, TIN | Identifies who reported to IRS |
| Header | Recipient Information | Your name, address, SSN | Must match your tax return exactly |
| 1a | Description of Property | Type and quantity sold | Example: "0.75 BTC" or "500 USDC" |
| 1b | Digital Asset Address/TX ID | Blockchain address or hash | Optional—not all brokers populate |
| 1c | Date Acquired | When you received the asset | May show "VARIOUS" for multiple lots |
| 1d | Date Sold or Disposed | Date of taxable event | The disposal date for this form |
| 2 | Gross Proceeds | Total received in USD | Key number for 2025 reporting |
| 3 | Cost or Other Basis | What you paid | Likely blank for 2025; required starting 2026 |
| 4 | Gain or Loss | Calculated gain/loss | Blank for 2025; auto-calculated when basis reported |
| 5a-5c | Short/Long-Term | Holding period classification | Affects your tax rate significantly |
| 6 | Covered/Noncovered | Basis reporting responsibility | Covered = broker tracks; Noncovered = you track |
| 7 | Wash Sale Loss Disallowed | Disallowed loss amount | Currently N/A for crypto (may change) |
| 8-10 | Additional Info | Federal withholding, state info | Supplemental transaction details |
Form 1099-DA Explained
Starting 2025, brokers must report your crypto sales on the new Form 1099-DA. Learn what this means for your tax filing.
Reconciling 1099-DA Against Your Records
You may receive forms that don't match your understanding of what happened. Here's how to reconcile:
Step 1: Match Each Form to Your Transaction History
For every 1099-DA received, locate the corresponding transaction in your records. The date, asset, and proceeds should align.
Step 2: Identify Discrepancies
Common issues include:
- Proceeds calculated at different USD prices (broker used their internal rate)
- Date acquired showing "VARIOUS" when you know specific dates
- Missing transactions that should have generated forms
- Forms for transactions you don't remember
Step 3: Determine If Discrepancies Matter
Small differences in USD pricing (within a few percent) are usually acceptable. The IRS expects some variation between broker rates and your records.
Large discrepancies or missing transactions require investigation. Contact your broker if you believe their reporting is incorrect.
Step 4: Document Everything
Keep records showing:
- Your calculation of proceeds (if different from 1099-DA)
- Your cost basis calculation and methodology
- Any correspondence with brokers about discrepancies
- Blockchain transaction hashes that prove your position
What If Your 1099-DA Is Wrong?
Brokers make mistakes. Here's what to do:
Minor Errors (Proceed Anyway)
If the error is small and clearly in your favor (broker reported higher proceeds than actual), you can report the correct lower amount. Keep documentation showing why your number is accurate.
Major Errors (Request Correction)
Contact the broker and request a corrected 1099-DA. They should issue a new form marked "CORRECTED" in the header.
Broker Won't Correct (Protect Yourself)
If the broker refuses to issue a correction for a legitimate error:
- Report the transaction accurately on your return
- Attach a statement explaining the discrepancy
- Keep thorough documentation
- Consider IRS Form 4598 to report incorrect information received
The IRS has matching systems that compare your return to 1099-DAs. If you report different numbers, expect a potential notice—but your documentation should resolve it.
Multiple 1099-DAs for the Same Transaction
Some transactions generate multiple forms:
Crypto-to-Crypto Swaps: Trading ETH for BTC might generate two 1099-DAs: one for the ETH disposal, one for the BTC acquisition (which itself becomes a future disposal).
Partial Fills: Large orders executed in multiple batches may generate separate forms for each fill.
Wrapped Token Conversions: Wrapping ETH to WETH might generate a 1099-DA even though the IRS hasn't clarified whether this is taxable.
Track carefully to avoid double-reporting or missing transactions.
The Cost Basis Problem (2025 Tax Year)
Here's the critical issue for 2025: brokers report proceeds but not cost basis. You must calculate basis yourself.
Why This Matters
If you report only the proceeds from your 1099-DA without subtracting your cost basis, you'll massively overpay taxes.
Example:
- 1099-DA shows: Sold 1 BTC for $95,000
- Your cost basis: $40,000 (you bought in 2022)
- Actual gain: $55,000
- If you report $95,000 as gain (ignoring basis): You'd owe tax on $40,000 extra
How to Track Cost Basis
You need records of every acquisition:
- Date of purchase
- Amount paid (including fees)
- Which specific units were sold (FIFO, LIFO, or specific identification)
Moonscape automatically tracks cost basis across all your exchanges and wallets, generating accurate basis information even when brokers don't report it.
Transactions Not on 1099-DA (But Still Taxable)
Just because you didn't get a 1099-DA doesn't mean the transaction isn't taxable. You must still report:
DEX Trades: Every swap on Uniswap, SushiSwap, or other decentralized exchanges.
Cross-Chain Bridges: Depending on bridge type, these may be taxable exchanges.
NFT Sales: Unless sold through a custodial marketplace that reports.
DeFi Activity: Yield farming harvests, liquidity pool exits, lending/borrowing liquidations.
Staking Rewards: Taxable as income when received (though separate from 1099-DA).
Airdrops: Taxable as income at fair market value when received.
The IRS expects complete reporting regardless of information forms.
International and Multi-Broker Complications
Many crypto users have complex situations:
Multiple Brokers
You may receive 1099-DAs from several exchanges. Each reports only what they know. Transfers between exchanges are NOT reported (these aren't taxable events), but your cost basis must transfer with the asset.
Foreign Exchanges
Non-US exchanges (Binance international, OKX, etc.) typically don't issue 1099-DA to US persons. You're still required to report all transactions.
If you have foreign accounts exceeding $10,000 aggregate at any point during the year, you may also have FBAR filing requirements (FinCEN Form 114).
Transfers Versus Sales
Sending crypto from Coinbase to Kraken is NOT a taxable event—it's just a transfer. But if Coinbase reports this as a disposition (which they shouldn't), you need to reconcile and document that it was a transfer, not a sale.
Reporting 1099-DA on Your Tax Return
Here's the filing workflow:
Step 1: Gather All 1099-DAs
Collect forms from every broker. Log into each exchange to download electronic copies if paper forms haven't arrived.
Step 2: Complete Form 8949
Each 1099-DA transaction goes on Form 8949:
- Part I for short-term (held ≤1 year)
- Part II for long-term (held >1 year)
Columns A through H capture: description, dates, proceeds, basis, adjustments, and gain/loss.
Step 3: Mark the Digital Asset Checkboxes
Form 8949 now has specific checkboxes for digital assets. This separates crypto from stocks/securities and makes your digital asset activity highly visible to the IRS.
Step 4: Transfer to Schedule D
Totals from Form 8949 flow to Schedule D, which calculates your overall capital gain or loss for the year.
Step 5: Attach to Form 1040
Schedule D and Form 8949 accompany your main tax return.
Penalties for Errors and Omissions
The IRS treats crypto reporting seriously:
Underreporting Income: If caught, you'll owe the tax plus interest. Penalties can reach 20-40% of underpayment.
Failure to File: Significant penalties for not filing when you had reportable transactions.
Fraud: Criminal penalties if the IRS determines willful tax evasion.
The existence of 1099-DA creates a paper trail. The IRS matching systems will flag returns where reported transactions don't match broker-reported 1099-DAs. Getting it right the first time is far easier than explaining discrepancies later.

Key Takeaways
- 1099-DA is mandatory for 2025 – Expect forms from all custodial brokers by February 2026
- Gross proceeds only (for now) – Cost basis reporting starts with 2026 tax year
- You must track your own basis – Don't report proceeds as pure gain
- Not all transactions get 1099-DA – DEX, DeFi, and non-custodial activity is still your responsibility
- Reconcile every form – Match to your records and document discrepancies
- The IRS is watching – Matching systems compare your return to broker reports
Form 1099-DA brings crypto into the same reporting framework as traditional assets. Treat it with the same seriousness you'd treat stock 1099-Bs.
