First identify the issuer and account
Do not combine similarly branded platforms without checking the issuer shown on the form. Record the account identifier, tax year and document version. Keep separate export folders for Binance.US, any international platform and every self-custody wallet.
Records to gather
- Form 1099-DA and any correction
- Binance.US trade and transaction export
- Deposits, withdrawals and distribution records
- Original acquisitions on other platforms
- Wallet transaction hashes
- Tax software imports and unmatched items
Record separation table
| Source | Keep separately | Reconcile through |
|---|---|---|
| Binance.US | Tax form, trades, deposits, withdrawals | Account and transaction IDs |
| Other Binance service | Independent export and account history | Cross-platform transfers |
| Self-custody wallet | Addresses, hashes, swaps and gas | On-chain send and receipt |
| Other exchange | Original purchase and fees | Withdrawal/deposit match |
Why platform separation matters
If an asset was acquired on another platform and later deposited into Binance.US, the Binance.US disposal record may not contain the earlier acquisition evidence. Conversely, importing multiple Binance-branded accounts as if they were one source can create duplicated or unmatched activity.
Review sequence
- Match the reported disposal to Binance.US activity.
- Determine whether the disagreement concerns proceeds or basis.
- For every outside deposit, find the corresponding withdrawal or wallet send.
- Locate the earliest relevant acquisition and fees.
- Confirm that tax software imported each source once and matched transfers correctly.
When to contact support
Contact the issuer when a specific reported item cannot be reconciled with its own underlying records, or if the form appears to belong to the wrong account or taxpayer. Provide non-sensitive transaction evidence and retain correspondence.
