Cryptocurrency trading has surged in popularity, prompting platforms like Coinbase to issue tax forms such as the 1099-B to help users report capital gains and losses. While this form is essential for accurate tax filing, requests for additional information can sometimes confuse recipients. This guide explains why these requests occur and how to address them effectively while optimizing your tax strategy.
How Coinbase Issues 1099-B
Coinbase adheres to IRS regulations by providing Form 1099-B, which details proceeds from digital asset transactions. The IRS treats cryptocurrencies as property, requiring users to report taxable events like buys, sells, and exchanges.
Key steps in Coinbase’s 1099-B process:
- Transaction Tracking: Records dates, types, amounts, and proceeds.
- Cost Basis Calculation: Uses algorithms to determine the original asset value (adjusted for fees).
- Holding Periods: Classifies gains as short-term (≤1 year) or long-term (>1 year).

Understanding Data Fields on the 1099-B
The form includes critical details for tax calculations:
- Acquisition/Disposition Dates: Determine holding periods.
- Fair Market Values: Reflect cryptocurrency values at transaction time.
- Proceeds: Gross amounts before fees.
- Cost Basis: Original purchase price adjusted for fees.
Example: A missing cost basis could lead to overreporting gains. Always verify this data against your records.
Summarizing Gains and Losses
- Short-Term Gains: Taxed at ordinary income rates (10–37%).
- Long-Term Gains: Taxed at reduced rates (0%, 15%, or 20%).
- Tax-Loss Harvesting: Offset gains with losses (up to $3,000/year). Avoid wash sales (repurchasing within 30 days).
Reconciling Cost Basis
Why it matters: Volatility in crypto markets makes accurate cost basis tracking essential.
- Hard Forks/Airdrops: Adjust cost basis for new assets received.
- Wallet Transfers: Ensure non-taxable movements aren’t misclassified.

- Contact Support: Provide transaction IDs/timestamps for corrections.
Pro Tip: Decentralized exchange trades may not appear on the 1099-B—report these manually.
Filing Your Tax Return
Forms to Use:
