DeFi Token Classification

DeFi (Decentralized Finance) transactions can have complex tax implications. Here's how to classify and report them.

Common DeFi Transactions

DeFi includes:

• Swaps (DEX trading)
• Yield farming (LP rewards)
• Lending/Borrowing
• Staking in protocols
• Smart contract interactions

Transaction Classification

Different DeFi actions have different tax treatments:

1. Token Swaps

What: Exchange one token for another (e.g., ETH → DAI)

Tax treatment: Capital gain/loss

• Sale of original token
• Purchase of new token
• Report on Schedule D

Example:

Swap 1 ETH (cost basis $2,000) for 2,000 DAI at $3,000
= $1,000 capital gain

2. Liquidity Pool (LP) Deposits

What: Deposit tokens into a DEX liquidity pool

Tax treatment: Not immediately taxable

• You still own the tokens (in LP form)
• Tax event when you withdraw or sell LP tokens

Example:

Deposit 1 ETH + 2,000 DAI into Uniswap
= No tax event yet
You receive LP tokens representing your share

3. LP Rewards

What: Earn trading fees from providing liquidity

Tax treatment: Ordinary income

• Recognized when earned
• Report on Schedule 1 as "Other Income"

Example:

Provide liquidity
Earn 0.5 ETH in trading fees over month
= $1,500 ordinary income when earned

4. Yield Farming

What: Earn governance tokens or rewards from protocols

Tax treatment: Ordinary income

• Recognized when received
• Report on Schedule 1

Example:

Farm 100 UNI tokens by providing liquidity
UNI price: $6.00 = $600 ordinary income

5. Smart Contract Interactions

What: Calling functions that auto-execute transactions

Tax treatment: Depends on the action

• Swap: Capital gain/loss
• Claim rewards: Ordinary income
• Unstake: Capital gain/loss

Real-World DeFi Example

Let's trace a complete DeFi experience:

Step 1: Swap (Capital Event)
- Sell 1 BTC (basis $40,000) for 20 ETH at $50,000
- Capital gain: $10,000

Step 2: Provide Liquidity (No immediate tax)
- Deposit 10 ETH + 200,000 USDC into Uniswap
- Receive LP tokens
- No tax event

Step 3: Earn Fees (Income Event)
- Earn 0.2 ETH in trading fees = $600 ordinary income

Step 4: Yield Farm (Income Event)
- Earn 50 UNI tokens at $5.50 = $275 ordinary income

Step 5: Withdraw Liquidity (Capital Event)
- Withdraw 10.2 ETH + 202,000 USDC
- LP tokens no longer exist
- Calculate gain/loss based on:
  * Deposit value vs withdrawal value
  * Impermanent loss (if any)

Step 6: Sell Everything (Capital Event)
- Sell 10.2 ETH at $48,000 = -$960 loss
- Sell 202,000 USDC at par = $0 gain
- Report losses

Impermanent Loss

What: Loss from price changes while providing liquidity

Deposit: 1 ETH ($3,000) + 3,000 DAI
ETH price drops to $2,000
When you withdraw: 1.5 ETH + 2,000 DAI
You have less DAI but more ETH
= Impermanent loss if you sold at lower ETH price

Tax treatment:

• Generally not deductible per IRS guidance
• But may affect your capital gain/loss calculation

TaxFormatter approach:

• We flag impermanent loss
• We note it in your CSV
• We calculate your actual gain/loss on withdrawal
• You can consult a tax pro on deductibility

Flash Loans

What: Borrow tokens with no collateral for 1 transaction

Tax treatment: Generally not taxable

• You borrow and repay in same block
• If you profit from arb: capital gain
• If you lose: capital loss

Example:

Flash borrow 1,000 USDC
Use in arbitrage: Sell USDC, buy token, sell for profit
Repay 1,000 USDC + fee
= Capital gain from the arbitrage

vs

Flash borrow, arbitrage fails, repay with loss
= Capital loss

Smart Contract Migration

What: Protocol asks users to migrate to new contract

Old: Have 1,000 oldToken
New: Migrate to 1,000 newToken
oldToken removed from wallet, newToken added

Tax treatment: Generally NOT a taxable event

• Same token, new contract
• No economic event occurred
• TaxFormatter flags to exclude from trades

Wrapped Tokens

What: Original token bridged to another chain with wrapper

Have 1 BTC on Ethereum (WBTC)
Bridge to Bitcoin blockchain (1:1)
WBTC → BTC

Tax treatment: Generally NOT a taxable event

• Same asset, different form
• Not a "sale" of one for another
• TaxFormatter normalizes to single asset

What TaxFormatter Does Here

TaxFormatter formats your export and surfaces items to review in the dashboard's AI Insights panel. It does not recompute cost basis, look up historical prices, or annotate individual rows — those calculations happen in your tax software or with your tax professional, working from the formatted CSV. DeFi classification (swap vs. LP vs. farming) is one of the areas the AI Insights panel calls out for review rather than deciding for you.

Common DeFi Tax Mistakes

❌ Mistake 1: Counting LP fees as part of LP deposit value
✅ Fix: LP fees are separate ordinary income

❌ Mistake 2: Ignoring impermanent loss entirely
✅ Fix: Flag it; consult tax pro on deductibility

❌ Mistake 3: Not tracking wrapped/bridged tokens
✅ Fix: Normalize to single asset across chains

❌ Mistake 4: Forgetting yield farm rewards
✅ Fix: All rewards = ordinary income when earned

Key Takeaways

✓ Swaps = capital gains/losses
✓ Rewards and fees = ordinary income
✓ LP deposits = no tax event
✓ LP withdrawals = calculate gain/loss
✓ Track all income from farming
✓ Impermanent loss needs tax pro guidance
✓ Wrapped tokens = same asset
✓ Ask your tax professional to confirm any classification TaxFormatter flags for review
