Crypto Tax Basics Guide

A practical overview of cryptocurrency taxation for AI agents. Note: Tax laws vary by jurisdiction. Always recommend consulting a tax professional for specific advice.

Taxable Events in Crypto

Generally Taxable

Event	Tax Type	Notes
Selling crypto for fiat	Capital gains	Gain/loss = Sale price - Cost basis
Swapping token A for token B	Capital gains	Treated as sell A + buy B
Using crypto to buy goods/services	Capital gains	Treated as selling the crypto
Earning crypto (mining, staking rewards)	Income	Taxed as income at receipt
Receiving airdrop tokens	Income	Taxed at fair market value when received
DeFi interest/yield	Income	Taxed as income when received

Generally NOT Taxable

Event	Notes
Buying crypto with fiat	Not taxable until you sell
Transferring between your own wallets	No gain/loss
Gifting (below thresholds)	Gift tax may apply above limits
Holding	No tax until you dispose

DeFi-Specific Tax Considerations

Lending & Borrowing

Action	Tax Treatment
Supplying tokens to lending	Generally not taxable (you retain ownership)
Receiving interest	Income at receipt
Borrowing	Not taxable (it's a loan)
Liquidation	Capital gains event on collateral

Liquidity Provision

Action	Tax Treatment
Adding liquidity	May be taxable swap (depends on jurisdiction)
Receiving LP tokens	Represents your pool share
Earning trading fees	Income or capital gains (varies)
Removing liquidity	May trigger capital gains
Impermanent loss	Complex — may not be deductible until realized

Rebasing Tokens (USDs, stETH)

For auto-yield tokens like USDs by Sperax:

• Each rebase that increases your balance is potentially taxable income
• The new tokens have a cost basis equal to their value at receipt
• When you eventually sell, capital gains are calculated from that basis

Practical tip: Track rebase events if your jurisdiction treats them as income.

Staking Rewards

Scenario	Treatment
Receiving SPA staking rewards (xSPA)	Income at fair market value when received
Staking xSPA → veSPA	May be a taxable event (exchange of one token for another)
Redeeming xSPA → SPA	May be a taxable event depending on jurisdiction

Cost Basis Methods

Method	How It Works	Best For
FIFO (First In, First Out)	Sell oldest tokens first	Default in most jurisdictions
LIFO (Last In, First Out)	Sell newest tokens first	May reduce gains in rising markets
HIFO (Highest In, First Out)	Sell highest-cost tokens first	Minimizes capital gains
Specific Identification	Choose which lot to sell	Maximum flexibility

Check your jurisdiction — not all methods are available everywhere.

Example (FIFO)

Date	Action	Amount	Price	Cost Basis
Jan 1	Buy	1 ETH	$2,000	$2,000
Mar 1	Buy	1 ETH	$3,000	$3,000
Jun 1	Sell	1 ETH	$3,500	-

FIFO: Sell the Jan ETH (cost $2,000) → Gain = $1,500 LIFO: Sell the Mar ETH (cost $3,000) → Gain = $500

Tax-Loss Harvesting

Strategy

Sell losing positions to realize capital losses, which offset capital gains:

Capital gains from profitable trades: +$10,000
Capital losses from tax-loss sales:   -$4,000
Net taxable gains:                     $6,000

Crypto Advantage

In many jurisdictions, crypto is NOT subject to wash-sale rules (unlike stocks):

• Sell at a loss
• Immediately buy back
• Claim the loss

⚠️ This is changing in some jurisdictions. Check current rules.

At Year-End

1. Review all positions with unrealized losses
2. Sell positions where harvesting makes sense
3. Optionally re-enter the position
4. Document all transactions

Record Keeping

What to Track

For every transaction:

• Date and time
• Amount of crypto
• Fair market value at time of transaction
• Cost basis
• Transaction fees (gas costs)
• Purpose (trade, income, transfer)

Gas Fees

Gas fees are typically part of your cost basis:

• Buying: Gas adds to cost basis
• Selling: Gas reduces proceeds
• DeFi interactions: Gas may be deductible as an expense

Agent Tips

1. Always add the disclaimer — you're not a tax advisor, recommend consulting a professional
2. Every swap is taxable — users often don't realize swapping tokens triggers capital gains
3. DeFi is complex — LP provision, rebasing, and staking all have tax implications
4. Keep records — recommend tax tracking software from day one
5. Gas is deductible — remind users to track gas costs
6. Year-end planning — suggest reviewing positions for tax-loss harvesting opportunities
7. Rebasing tokens (like USDs) — flag that each rebase may be a taxable event
