Crypto Tax Basics
In most jurisdictions, cryptocurrency is treated as property, not currency. This means every disposal—selling, trading, spending—is a taxable event. Understanding the two main categories of crypto taxation is essential.
Capital Gains Tax
When you sell crypto for more than you paid, you owe capital gains tax on the profit. The rate depends on how long you held the asset:
Short-Term (held ≤ 1 year): Taxed as ordinary income at your marginal rate (10-37% in the US).
Long-Term (held > 1 year): Preferential rates (0%, 15%, or 20% in the US depending on income).
| Taxable Income | Long-Term Rate | Short-Term Rate |
|---|---|---|
| $0 - $44,625 | 0% | 10-12% |
| $44,625 - $492,300 | 15% | 22-35% |
| $492,300+ | 20% | 37% |
Ordinary Income
Some crypto receipts are taxed as ordinary income at your marginal rate, regardless of holding period:
- Mining/Staking rewards: Taxable when received at fair market value
- DeFi yield: Interest, farming rewards, LP fees
- Airdrops: Taxable at FMV when you gain control
- Payment for services: Freelance income, salaries in crypto
💡 Key Insight
The timing of income recognition matters enormously. If you receive an airdrop worth $10,000 and it later drops to $1,000, you still owe tax on $10,000 of income. However, selling at $1,000 creates a $9,000 capital loss you can use to offset gains.

Tax-Loss Harvesting Tip: If you have losses, you can offset gains. Up to $3,000 in net losses can offset ordinary income annually. Harvest losses before year-end to reduce your tax bill.
DeFi-Specific Tax Events
DeFi creates complex tax situations that traditional finance never imagined. Here's how common DeFi activities are generally treated:
Token Swaps
Every swap is a taxable event. Trading ETH for USDC is a disposal of ETH—you realize a gain or loss based on your cost basis. Swapping 100 times creates 100 taxable events, each requiring cost basis tracking.
Liquidity Providing
LP taxation is complex and somewhat unsettled:
Deposit: Adding to LP pool may be a disposal (unclear)
LP Fees: Taxable as ordinary income when earned
LP Rewards: Governance tokens taxable as income when received
Withdrawal: May trigger gain/loss on original deposit
Impermanent loss is not directly tax-deductible—it's reflected in your withdrawal proceeds being lower than if you'd simply held.
Lending & Borrowing
Lending: Interest received is ordinary income. Each interest payment is a taxable event.
Borrowing: Taking a loan is NOT a taxable event—you haven't disposed of your collateral. However, if you get liquidated, that's a forced sale with potential gain/loss.
Staking
Staking rewards are generally taxable as ordinary income when received. The cost basis of received tokens is their FMV at receipt. Later selling creates a capital gain/loss.
Airdrops
Airdrops are taxable as ordinary income when you gain "dominion and control"—typically when tokens appear in your wallet. If an airdrop requires claiming, taxation may be deferred until claimed.
⚠️ The Airdrop Trap
Receiving a $10,000 airdrop creates $10,000 of taxable income. If the token drops 90% before you sell, you owe tax on income you never realized. Strategy: sell enough immediately to cover estimated tax liability.
Bridging
Bridging assets between chains is generally NOT a taxable event if you receive the same asset on the other side. However, if you bridge ETH and receive WETH, some argue this could be a taxable swap. Guidance is unclear.
Tax-Loss Harvesting
Tax-loss harvesting is one of the few ways to legally reduce your crypto tax burden. By strategically realizing losses, you can offset gains and reduce your tax bill.
How It Works
1. Identify positions with unrealized losses
2. Sell to realize the loss
3. Use loss to offset capital gains (reduces tax)
4. Optionally repurchase the same asset (no wash sale rule for crypto*)
* Important: The wash sale rule (which prevents claiming losses if you repurchase within 30 days) currently doesn't apply to crypto in the US, though this may change.
Loss Offset Rules
- Short-term losses first offset short-term gains
- Long-term losses first offset long-term gains
- Excess losses of either type offset the other
- Net capital losses can offset up to $3,000 of ordinary income annually
- Remaining losses carry forward indefinitely
Harvesting Strategy
Example: Portfolio with $20K gains and $15K unrealized losses
Without harvesting: Tax on $20,000 gains
With harvesting: Tax on only $5,000 net gains
At 15% long-term rate: Save $2,250 in taxes
Harvest losses before year-end to offset current-year gains. Consider the trade-off: you're resetting cost basis, which affects future gains.
Record-Keeping & Cost Basis
Cost Basis Methods
When you sell crypto purchased at different times and prices, you need a method to determine which "lot" you're selling:
FIFO (First In, First Out): Oldest purchases sold first. Often results in higher gains (longer holding, more appreciation).
LIFO (Last In, First Out): Newest purchases sold first. Can minimize gains if recent purchases were at higher prices.
Specific Identification: Choose which lot to sell. Most tax-efficient but requires detailed records.
HIFO (Highest In, First Out): Sell highest-cost lots first to minimize gains. Some tax software supports this.
What to Track
For every transaction, you need:
- Date and time of acquisition
- Cost basis (what you paid, including fees)
- Date and time of disposal
- Proceeds (what you received, minus fees)
- Transaction type (trade, income, transfer)
Tracking Tools
- Koinly: Most DeFi-friendly, supports complex protocols
- TokenTax: Strong DeFi coverage, tax professional partnerships
- CoinTracker: Good UI, integrates with TurboTax
- ZenLedger: Solid all-around option
Common Mistakes to Avoid
❌ Ignoring Small Transactions
Every swap, no matter how small, is taxable. $10 trades add up and create audit risk if unreported.
❌ Forgetting Cost Basis on Income
When you receive staking rewards or airdrops, their FMV becomes your cost basis. Track this or you'll pay tax twice.
❌ Not Tracking Fees
Gas fees add to your cost basis (reducing gains) or can be deducted as expenses in some cases.
❌ Assuming Privacy = No Taxes
Blockchain is public. Tax authorities increasingly use chain analysis. Don't assume DeFi activity is invisible.
❌ Waiting Until Tax Season
Trying to reconstruct a year of DeFi activity in April is painful. Track throughout the year.
Frequently Asked Questions
Do I owe taxes if I didn't cash out to fiat?
Yes. Every crypto-to-crypto trade is a taxable event. Trading BTC for ETH triggers a capital gain/loss on the BTC. You don't need to convert to fiat for taxes to apply.
What if I can't find my cost basis?
The IRS doesn't accept "I don't know" as cost basis. You must reconstruct records from exchange history, blockchain data, or historical prices. If truly impossible, using $0 cost basis is conservative (you pay more tax) but defensible.
Are transfers between my own wallets taxable?
No. Moving crypto between your own wallets is not a taxable event. However, tracking is important to maintain cost basis history. Use wallet labels in tracking software.
What about NFTs?
NFTs are treated like other property. Buying with crypto triggers a disposal of that crypto. Selling an NFT triggers a capital gain/loss. Some NFTs may qualify as collectibles (higher 28% rate).
Should I use a crypto tax professional?
If you have significant DeFi activity, complex positions, or large gains, yes. The cost of professional help is usually far less than mistakes from DIY filing. Find CPAs who specialize in crypto.

Conclusion: Stay Compliant, Sleep Well
Crypto taxes are complex, but they're not optional. The cost of non-compliance—penalties, interest, and potential criminal liability—far exceeds the cost of proper reporting. Build good habits: track throughout the year, use quality software, and consult professionals when needed.
The good news is that proper tracking enables tax optimization. Tax-loss harvesting, strategic lot selection, and timing of income recognition can legitimately reduce your burden. The traders who master crypto taxes don't just stay compliant—they keep more of their gains.
Start tracking today. Your future self (and your accountant) will thank you.
