Tax reporting from crypto custodians refers to the statements a custodian provides to help you and the IRS account for your activity: transaction histories, gain/loss reports, and information returns such as Form 1099. What you receive depends on the custodian and the tax year, and custodian reports often still need reconciliation against your own records before they go on a return. This is general information, not tax advice, confirm details with a CPA.
Do Crypto Custodians Issue 1099s?
It varies, and the rules are changing. Historically, crypto reporting was inconsistent: some platforms issued a Form 1099-MISC (for rewards or income) or a 1099-B-style summary, others issued nothing, and many provided only a downloadable transaction history. The result was that the burden of calculating and reporting gains often fell on the investor.
That is shifting with Form 1099-DA, Digital Asset Proceeds From Broker Transactions, which the IRS introduced for digital asset brokers under regulations finalized in 2024. Under the phased rollout, brokers, which can include certain custodians and platforms, are required to report gross proceeds for applicable digital asset sales, with cost-basis reporting phased in later. The exact timing and who qualifies as a "broker" are governed by the regulations and their effective dates, so confirm current-year requirements. See what is Form 1099-DA.
Key point: even where a custodian issues a 1099, you remain responsible for the accuracy of your return. A 1099 is an information return; it does not replace your own recordkeeping. For where reporting fits into choosing and using a custodian, see the crypto custody hub.
What Statements a Custodian Typically Provides
Depending on the provider, you may receive some or all of:
- Transaction history / activity statement. A chronological export of deposits, withdrawals, trades, and rewards.
- Realized gain/loss report. A computed summary of gains and losses for sales during the year, dependent on the custodian's cost-basis assumptions.
- Information returns. A Form 1099 (increasingly Form 1099-DA) reporting proceeds and, over time, basis to you and the IRS.
- Income statements. Records of staking rewards, interest, or other income the custodian paid or facilitated.
These feed the forms you actually file, typically Form 8949 for crypto investors and Schedule D for capital gains, with income reported on the appropriate schedule.
Why Custodian Reports Still Need Reconciliation
Custodian statements are a starting point, not a finished return, because:
- Transfers vs. sales. Moving assets between your own wallets is generally not a taxable sale, but a custodian may not know the cost basis of assets you transferred in, leading to missing or incorrect basis. See are crypto wallet transfers taxable and how to separate crypto transfers from taxable sales.
- Multiple custodians. If you hold assets across several platforms, no single statement sees the full picture, and lots can be reported inconsistently. See how do I report crypto from multiple exchanges.
- Cost-basis method. The custodian's default method may differ from the method you intend to use, such as specific identification. See what is specific identification for crypto.
- Gaps and errors. Historical data, forks, airdrops, and assets from closed platforms may be missing or mislabeled, requiring reconstruction.
For trusts and LLCs holding crypto in custody, entity-level reporting adds another layer; see crypto tax reporting for trusts and crypto tax reporting for LLCs.
A Reconciliation Checklist
- Download the full-year transaction history from each custodian.
- Identify internal transfers and exclude them from taxable sales.
- Confirm cost basis for assets transferred in from elsewhere.
- Compare the custodian's gain/loss report against your own calculation.
- Match any 1099 (including 1099-DA) totals to your records and resolve differences.
- Record staking, interest, and reward income separately.
- Keep supporting records in case the IRS requests them.

Related Questions
Will my custodian's 1099 match what I actually owe?
Not necessarily. A 1099 reports what the custodian knows, often proceeds, and increasingly basis, but it may not reflect transfers in from other platforms, your chosen cost-basis method, or activity on other custodians. Use it as one input and reconcile against your complete records. Differences between a 1099 and your return should be documented and, where needed, reviewed with a CPA.
Does a custodian report my crypto to the IRS?
Increasingly, yes, for brokers subject to Form 1099-DA reporting, which is being phased in for digital asset sales. Whether a particular custodian is a reporting broker and what it must report depends on the regulations and the tax year. Even where the custodian reports, you are still responsible for filing a complete and accurate return. Confirm current-year requirements with a tax professional.
What if my custodian provides no cost-basis information?
You will generally need to reconstruct basis from your own records, acquisition dates, amounts, and prices, including assets transferred in from other wallets or platforms. Missing basis is common and can lead to overstated gains if defaulted to zero. See how to reconstruct crypto cost basis and work with a CPA where the gaps are material.
