DeFi (decentralized finance)

Lending, borrowing, swapping, and yield activity run by smart contracts rather than an exchange. Each swap is generally a taxable disposal; rewards are generally income when received.

What is DeFi?

Lending, borrowing, swapping, and yield activity run by smart contracts rather than an exchange. Each swap is generally a taxable disposal; rewards are generally income when received.

Why it matters on your return

DeFi produces more taxable events per dollar than any other crypto activity. Each swap is a disposal, each liquidity pool deposit may be an exchange for LP tokens, and yield arrives as income. Software often mislabels these, so DeFi-heavy years need manual review.

Example

You deposit ETH and USDC into a liquidity pool, receive LP tokens, earn rewards for six months, then withdraw. That can be two disposals, six months of ordinary income, and a final exchange back, each at a different value.

Is providing liquidity a taxable event?

As of September 2026 the IRS has issued no guidance on liquidity pool deposits or LP tokens; its only 2025 staking guidance, Rev. Proc. 2025-31, covers exchange-traded trusts that stake, not individuals. Most practitioners treat the receipt of LP tokens as an exchange, which makes it taxable; a minority position treats it as a deposit. We document the position taken.
