Crypto Tax Season 2026: Complete Guide

The 2025 tax year (filed in 2026) represents a watershed moment for crypto taxation in the United States. For the first time, many brokers and exchanges are required to send 1099-DA forms, and several longstanding ambiguities in DeFi and staking taxation have been addressed by IRS guidance.

What's New for 2026

1099-DA Reporting (Finally Here) Starting with 2025 transactions, qualifying crypto brokers (centralized exchanges, custodial wallet providers) must issue 1099-DA forms to customers. This parallels the 1099-B system used for stocks. Key points:

• You'll receive a 1099-DA from any US-regulated exchange where you transacted in 2025
• The IRS will receive a copy automatically
• Even small transactions are reportable — there's no de minimis threshold for crypto

DeFi Protocol Rules The IRS has issued guidance clarifying that: - Swapping tokens on a DEX is a taxable event (same as before) - Providing liquidity to an AMM pool is NOT a taxable event when entering or exiting (new clarity) - Impermanent loss is not deductible until you exit the pool and realize the loss - Staking rewards are taxable as ordinary income when received

NFT Tax Treatment NFTs are taxed as collectibles when held for over 1 year, meaning a maximum 28% long-term capital gains rate (higher than the 20% rate for most other crypto assets).

Common Mistakes to Avoid

1. Missing DeFi activity: Many taxpayers forget to report DEX swaps, yield farming rewards, and airdrops. Tax software that connects directly to your wallet addresses via API can catch these.

2. Using wrong cost basis method: FIFO (first-in, first-out) is the default, but you can elect specific identification to minimize taxes. This election must be consistent throughout the year.

3. Not reporting foreign exchange activity: US citizens must report crypto held on foreign exchanges on FBAR and Form 8938 if thresholds are met.
