Does Coinbase report to the IRS? Yes — they send 1099-MISC forms for staking rewards and referral income, 1099-B forms for certain sales, and starting with 2025 transactions, 1099-DA forms covering gross proceeds from crypto dispositions. The IRS gets a copy of everything Coinbase sends you. But here’s the part most articles skip: the numbers on your Coinbase 1099 are often wrong. Not because Coinbase is careless, but because they only see what happened inside their own walls. If you’ve ever moved crypto into Coinbase from another wallet (and most active investors have), the cost basis on your 1099 is almost certainly incomplete. We see this pattern constantly with new clients, and it’s why “just file what Coinbase sent me” is one of the most expensive mistakes an individual investor can make. This guide breaks down exactly what Coinbase reports, what they can’t see, and what that means for your actual tax bill.

For how these reported gains actually get taxed once they hit your return, see our full guide to how crypto is taxed.

Does Coinbase Report to the IRS? Here’s What They Send

1099-MISC, 1099-B, and 1099-DA crypto tax forms explained
Coinbase sends three types of tax forms to the IRS — each covering different activity. The 1099-DA is new for 2025.
Coinbase sends the IRS three main types of tax forms, depending on what you did during the year. The IRS gets its own copy of each form at the same time you do.

Form 1099-MISC: Income Over $600

If you earned more than $600 in a calendar year from staking rewards, Learn & Earn tasks, USDC rewards, or referral bonuses, Coinbase issues a 1099-MISC. That income goes on your tax return as ordinary income, taxed at your regular rate (not the lower capital gains rate). Important: the $600 threshold applies to the income itself, not to your gains. Stake $50,000 of ETH, earn $2,000 in rewards, and you get a 1099-MISC for the $2,000. Even if you never sold, that $2,000 is taxable in the year you received it.

Form 1099-B: Sales (for Some Accounts)

Coinbase has historically issued 1099-B forms for certain customer sales, though the scope has varied year to year. 1099-B shows proceeds from sales but often has cost basis gaps (more on that in the next section). For 2025 tax years and beyond, the 1099-B is being replaced by the new 1099-DA for crypto.

Form 1099-DA: The New Broker Reporting Standard

Starting with 2025 transactions (forms issued in early 2026), Coinbase is required to issue 1099-DA forms under the broker reporting rules from the Infrastructure Investment and Jobs Act. The 1099-DA covers:
  • Gross proceeds from sales, trades, and other dispositions
  • Cost basis reporting is phased in starting with 2026 transactions (forms issued in 2027), for transactions where the asset was acquired on the same exchange
  • Transfers of assets in from elsewhere will still lack cost basis for the foreseeable future
If you received a 1099-DA from Coinbase covering 2025 activity, it shows your total dispositions but probably doesn’t show your cost basis for assets you moved in from a self-custody wallet, another exchange, or a DEX. That’s a problem we’ll come back to.
The short version: Coinbase sends the IRS income numbers (1099-MISC) and sale/disposition numbers (1099-B, now 1099-DA). The IRS runs automated matching against what you report on your return. If your return doesn’t account for what Coinbase told them, expect a notice.

Why Your Coinbase 1099 Is Often Wrong

How crypto transfers break cost basis reporting on Coinbase 1099
When you move crypto through multiple wallets and exchanges, Coinbase can only see the final transfer in — not what you originally paid for it.
This is the part that costs investors thousands of dollars every year. Coinbase can only see the transactions that happen inside Coinbase. If you bought 1 ETH on Kraken in 2021, moved it to your Ledger, then transferred it to Coinbase in 2025 and sold it for $4,000, Coinbase sees a $4,000 sale with no cost basis. Their 1099 shows $4,000 in proceeds. If you file what Coinbase sent you without reconciling the actual purchase history, the IRS treats your basis as $0 and taxes you on the full $4,000. Your actual gain? Maybe $1,000 if you bought that ETH at $3,000. Possibly zero. Potentially a loss. That’s not a hypothetical. We’ve reviewed hundreds of Coinbase 1099s for clients, and the same pattern shows up over and over. People see a big number on the form, assume the exchange got it right, and either:
  1. Pay tax on gains they didn’t actually have, or
  2. File something off the cuff, get audited, and owe back-tax plus penalties
Both outcomes are preventable. But only if you reconcile the full picture instead of trusting one form.

The specific ways Coinbase 1099s go wrong

  • Missing cost basis on transferred-in assets. The single biggest issue. Any crypto you moved into Coinbase from another wallet has no basis data on the 1099. (Not sure what cost basis means? See our guide: What is Cost Basis in Crypto?)
  • Gross proceeds shown as gains. 1099-DA shows total dollars out the door, not net profit. Reading it as “your gain” will massively overstate your tax.
  • Staking rewards double-counted. If you earn staking income (1099-MISC) and then later sell those rewards at a gain (1099-DA), both events are taxable. Many people forget to track the basis of the rewards at the time they received them.
  • Wrong holding period. Short-term vs long-term capital gains rates differ significantly. If Coinbase doesn’t know when you actually acquired the asset (because you transferred it in), the holding period shown may be wrong.
  • Internal transfers flagged as sales. Moving crypto between your own wallets isn’t a taxable event, but poorly labeled transactions sometimes appear as dispositions.
Google’s own AI Overview on this exact search flags the issue: “If you transferred assets into Coinbase, your 1099-DA may lack the cost basis, which the IRS may assume is $0, leading to potential overreporting.” When Google’s AI is telling people their 1099 is wrong, that’s a strong signal this isn’t a fringe problem.

What Coinbase Doesn’t Report

What Coinbase reports to the IRS versus what remains your responsibility to report
Coinbase only reports activity on their own platform. DeFi, DEX swaps, self-custody trades, and activity on other exchanges are your responsibility to report.
Coinbase reporting only covers activity on Coinbase itself. Everything else is invisible to them, which means it’s also unreported to the IRS by them. But that doesn’t mean it’s tax-free. You’re still legally required to report it. Here’s what falls outside Coinbase’s reporting:
  • Self-custody wallets: MetaMask, Ledger, Trezor, Rabby, Phantom. If you sent ETH from Coinbase to your own wallet, Coinbase sees the transfer out. They don’t see what you did with it afterward.
  • Decentralized exchanges: Uniswap, Curve, Jupiter, Raydium, 1inch. Every swap is a taxable disposition for US investors. No 1099 is sent for any of it.
  • DeFi protocols: Lending on Aave, liquid staking on Lido, yield farming anywhere. Supplying assets, claiming rewards, liquidations — all potentially taxable. All unreported by any third party. See: How to Pay Taxes on DeFi
  • NFT marketplaces: Secondary sales on OpenSea, Blur, Magic Eden. The marketplaces generally don’t issue 1099s. You’re still on the hook for capital gains.
  • Cross-chain bridges: Bridging from Ethereum to Arbitrum (or any L1 to L2, or between chains). The IRS has not issued definitive guidance on whether a bridge is a taxable event in all cases, but many bridges involve swaps that clearly are.
  • Centralized exchanges outside the US: If you used an offshore exchange, don’t assume zero reporting. CARF (the Crypto Asset Reporting Framework) starts routing non-US exchange data to the IRS in 2027.
The IRS doesn’t care which app you used. A taxable event is a taxable event whether it happened on Coinbase or on a DEX you accessed through a hardware wallet. “No 1099 was sent” is not a defense.

What does Form 1099-DA change for Coinbase users?

The 1099-DA is new, and it matters more than most people realize. Before 2025, crypto reporting was fragmented. Some exchanges issued 1099-B, some issued 1099-MISC, some issued nothing at all. The IRS was getting partial data at best. That’s over. Starting with the 2025 tax year, every US “broker” (which now includes centralized crypto exchanges) is required to issue Form 1099-DA to both you and the IRS. For 2025, the form shows gross proceeds only. For 2026 transactions, exchanges will also report cost basis for assets that were acquired on their platform and never left. For assets transferred in from elsewhere, cost basis reporting remains your responsibility.

What this means for you

  • The IRS is getting dramatically more crypto data. Expect more CP2000 notices.
  • The gap between what Coinbase reports and what you actually owe is going to get scrutinized.
  • “The exchange didn’t tell me” stopped being a valid excuse the moment 1099-DA went live.
  • Multi-exchange users, active DeFi users, and anyone with long crypto history will have the biggest reconciliation burden.
The new reporting standard doesn’t do your taxes for you. It tells the IRS what to ask about. Your job, or your accountant’s job, is to make sure the numbers you report match reality across every wallet, exchange, and protocol you touched.

How the IRS Uses Coinbase Data

The IRS has been collecting crypto data for nearly a decade, long before mandatory reporting. In 2016, the IRS issued a John Doe summons against Coinbase and obtained records on approximately 14,000 accounts. Follow-up summonses hit Kraken in 2021 and other exchanges since. These weren’t investigations of specific taxpayers. They were broad sweeps aimed at identifying people with crypto activity who hadn’t reported it. Now that 1099-DA reporting is live, the process is automated. Here’s what happens:
  1. Coinbase files 1099-DA and 1099-MISC forms with the IRS at the same time they send yours.
  2. The IRS runs the data through the Automated Underreporter program (AUR), matching reported income against your tax return.
  3. If there’s a mismatch, you receive a CP2000 notice. It’s not technically an audit, but it proposes additional tax, penalties, and interest based on what the IRS thinks you owe.
  4. You have a limited window to respond with corrected figures (including cost basis they didn’t have). If you don’t respond, the proposed assessment becomes official.
CP2000 notices have been hitting crypto investors in large numbers since 2021. The pattern is almost always the same: someone got a 1099 showing a big number, didn’t reconcile it, and the IRS treated the entire proceeds amount as gain. Responding to a CP2000 isn’t hopeless. If your actual gain was lower (or a loss), you can document it. But you need the data: the acquisition date, the acquisition price, the transfers between wallets, the cost basis methodology. That’s what a proper reconciliation gives you, and it’s what a Coinbase 1099 alone cannot.

What You Actually Need to Do

If you have any crypto activity outside of Coinbase, filing the Coinbase 1099 by itself is not enough. Here’s what a complete filing looks like:

1. Gather every wallet and exchange

List every wallet address you’ve ever used, every centralized exchange you’ve signed up for, every DeFi protocol you’ve touched. Yes, even the ones you forgot about. Especially those.

2. Pull your complete transaction history

For centralized exchanges, export the full CSV. For wallets, export the transaction history or use a block explorer. For DeFi, this is where it gets hard, because protocols don’t give you a clean report.

3. Reconcile using crypto tax software

Tools like Koinly, Awaken, and Summ can ingest your wallets and exchanges, match transfers between them, and apply a consistent cost basis methodology (FIFO, LIFO, HIFO, or specific identification, depending on what the IRS currently allows). Good software gets you 80% of the way.

4. Fix what the software gets wrong

This is the part people underestimate. Every reconciliation we do for clients includes manual corrections. Missing cost basis, unlabeled transactions, failed swaps shown as successful, airdrops miscategorized, bridges counted as sales. Software surfaces the issues. You still need judgment to resolve them correctly.

5. File the complete picture

Your actual tax return reports the reconciled numbers on Form 8949 and Schedule D, not the raw numbers from any single 1099. If the Coinbase 1099 says $40,000 in proceeds but your actual gain (after cost basis) is $8,000, you report $8,000. You can (and should) keep the reconciliation documentation in case the IRS asks.

When to Hire a Crypto Tax Professional

Doing this yourself works fine if your activity is simple. If any of these apply, though, the math on DIY starts to break down:
  • You’ve used Coinbase plus at least one other exchange or wallet
  • You’ve touched DeFi protocols, DEXs, or LP positions
  • Your Coinbase 1099 proceeds look obviously higher than what you actually made
  • You have multiple years of unfiled crypto activity
  • You received a CP2000 notice or other IRS correspondence about crypto
  • You have more than a thousand transactions
  • You have significant gains (or losses) and want to make sure the tax treatment is right

FAQ

Can the IRS see my Coinbase account?

Yes. The IRS has direct access to Coinbase reporting through 1099-DA, 1099-MISC, and the earlier 1099-B. They also obtained account data on approximately 14,000 Coinbase users through a 2016 John Doe summons. Coinbase reports your gross proceeds, staking income, and other reportable activity automatically. The IRS matches those numbers to your tax return.

Do I have to pay taxes on Coinbase withdrawals?

Withdrawing crypto from Coinbase to your own wallet is not a taxable event. Moving your own assets between wallets you control doesn’t trigger tax. What is taxable: selling crypto, trading one crypto for another, spending crypto on goods or services, earning crypto (staking, referrals, mining, airdrops). Cashing out to USD on Coinbase is taxable. Transferring BTC from Coinbase to your Ledger is not.

What happens if I don’t report my Coinbase transactions?

The IRS will likely notice. Coinbase sends them your 1099 data, and the Automated Underreporter program matches it against your return. If there’s a gap, you get a CP2000 notice proposing additional tax, penalties, and interest. Failure to respond turns the proposed assessment into an official one. In serious cases (large amounts, willful non-reporting), charges can escalate to tax evasion, which is a felony. The IRS accuracy-related penalty is 20% of the underpayment for substantial understatements; civil fraud penalties can reach 75%.

What is a 1099-DA and does Coinbase send one?

The 1099-DA is a new IRS form specifically for crypto broker reporting. It’s required under the Infrastructure Investment and Jobs Act broker rules, and Coinbase is required to issue it starting with the 2025 tax year (forms issued in early 2026). The form shows gross proceeds from dispositions. Cost basis reporting phases in starting with 2026 transactions, but only for assets acquired on Coinbase and never transferred in. Yes, if you had reportable activity on Coinbase in 2025, you should expect a 1099-DA.

Do I need to report crypto if I didn’t receive a 1099?

Yes. The absence of a 1099 doesn’t mean the activity is tax-free. Taxable events include every trade, swap, sale, and payment, whether on a centralized exchange, a DEX, or peer-to-peer. If you earned crypto (staking, mining, airdrops, referrals), that’s taxable income even without a 1099. The 1099 is a reporting tool for the IRS’s convenience, not the source of your tax obligation.

Why is the cost basis on my Coinbase 1099-DA wrong?

Because Coinbase can only see what happened on Coinbase. If you bought crypto elsewhere and transferred it in, Coinbase has no record of what you paid for it, so they report cost basis as unknown (or $0). When you sell, the 1099 shows the full proceeds with no basis offset, which makes your gain look much larger than it actually is. Fixing this requires reconciling the full transaction history across every wallet and exchange you’ve used, then applying the correct basis to each sale.

Stop Paying Tax on Gains You Didn’t Have
