To prepare crypto records for a CPA, gather and organize your wallet addresses, exchange and custodian statements, cost basis records, income events (staking and airdrops), transfers between your own wallets, trust and LLC ownership documents, and any tax forms received, then hand the CPA a clean dataset before preparation begins. Clean records generally produce more defensible reporting.
What "Preparing Crypto Records" Means
Preparing crypto records is the process of assembling a complete, reconciled history of every digital-asset account and transaction the CPA needs to compute gains, losses, and income. Because the IRS generally treats digital assets as property, each disposal can be a taxable event, and the CPA depends on your records to apply a consistent cost-basis method such as specific identification. The quality of the reporting usually tracks the quality of the underlying records, so the goal is a dataset the preparer can rely on without guessing.
This work sits inside broader crypto wealth management, where tax coordination is one piece of a larger plan.
Records to Gather
- Exchange transaction histories (one export per exchange, see how to report crypto from multiple exchanges).
- Custodian statements, including any qualified-custodian holdings reports.
- Wallet addresses (public addresses, not private keys or seed phrases).
- Transfer records linking your own wallets and accounts.
- Cost basis records (acquisition date, amount, and price).
- Sale and swap history.
- Staking rewards, with the date and fair market value at receipt.
- Airdrops, with the date and value at receipt.
- Token unlock and vesting records.
- Trust and LLC ownership documents.
- Prior-year tax reports.
- Forms 1099-DA, 1099-B, or other forms if received.
Data Cleanup Steps
- List all wallets and accounts. Build one master inventory of every exchange login, custodian account, and on-chain wallet address.
- Separate personal, trust, and LLC assets. Tag each account to the right owner so entity-level activity flows to the correct return.
- Identify transfers between wallets you own. A move between your own wallets is generally not a taxable sale; see how to separate transfers from taxable sales so the CPA does not count it as income.
- Match deposits and withdrawals. Reconcile each outbound transfer to its inbound counterpart to avoid duplicate or phantom transactions.
- Flag missing cost basis. Where acquisition data is absent, mark it for cost basis reconstruction rather than leaving a gap.
- Export reports for the CPA. Produce clean CSV or PDF exports and a short summary of open questions.
Why This Matters
Missing or disorganized records can lead to incorrect gain or loss reporting, double-counted income, or tax positions you cannot support if questioned. A CPA may need extra time, and extra fees, to reconstruct activity from incomplete data. Good records do not change what you owe, and they do not remove market, custody, or tax risk, but they generally make the return easier to defend and faster to file. Where exchanges have closed or data is gone, document what you can, see what to do if crypto tax records are missing.
Related Questions
What records does a CPA actually need for crypto?
Generally, a CPA needs every exchange and custodian history, wallet addresses, cost basis for each lot, income events such as staking and airdrops, transfer records, and any 1099 forms received. The exact set depends on your facts, so confirm scope with your preparer.
Are transfers between my own wallets taxable?
Moving crypto between wallets you control is generally not a sale and not by itself a taxable event, though it still needs to be documented so it is not mistaken for income. Treatment depends on the facts; consult a qualified tax professional.
What if I cannot find my cost basis?
You may be able to reconstruct it from blockchain explorers, historical price data, and old exchange records. If basis cannot be established, a CPA can discuss how to handle the position; see what if I cannot prove my crypto cost basis.
When should I start preparing records?
As early as practical, ideally well before the filing deadline, so there is time to fix gaps. Reconstructing a year of activity under deadline pressure generally raises both cost and error risk.
