  • Long-term holding (>1 year) saves up to 17% in taxes vs short-term
  • Tax-loss harvesting offsets gains and reduces tax bill
  • Specific identification lets you choose highest cost basis lots
  • DeFi activities (swaps, LP, staking) are taxable events

Taxable Events

Understanding what triggers taxes is the first step to optimization. Not every crypto activity is taxable.

Taxable Events

  • • Selling crypto for fiat
  • • Trading crypto-to-crypto
  • • Buying goods with crypto
  • • Receiving staking rewards
  • • Airdrops (at FMV)
  • • Mining/earning crypto

NOT Taxable

  • • Buying crypto with fiat
  • • Holding crypto
  • • Transferring between wallets
  • • Gifts (up to $17k/person)
  • • Donations to charity

Holding Period Benefits

US Capital Gains Tax Rates (2026)

Short-Term (<1 year)

Taxed as ordinary income:

  • • 10-37% depending on bracket
  • • High earners pay 37%

Long-Term (>1 year)

Preferential rates:

  • • 0% (income <$44k single)
  • • 15% (income $44k-$492k)
  • • 20% (income >$492k)

Key Insight

Waiting 1 day can save 17% in taxes. If you're at 364 days holding, wait one more day before selling to qualify for long-term rates.

Tax-Loss Harvesting

Tax-loss harvesting is selling assets at a loss to offset capital gains. This is one of the most powerful legal tax reduction strategies.

How Tax-Loss Harvesting Works

Step 1:You have $10,000 in realized gains
Step 2:Sell losing position for $8,000 loss
Result:Only pay tax on $2,000 net gain

Wash Sale Warning

Traditional wash sale rules (no repurchase within 30 days) may apply to crypto. IRS guidance is evolving. To be safe, wait 30 days before rebuying the same asset after harvesting.

Specific Identification

Instead of FIFO (First In First Out), specific identification lets you choose which tax lots to sell. This can significantly reduce your tax bill.

FIFO vs Specific ID Example

You bought BTC at: Lot 1 ($30k), Lot 2 ($60k), Lot 3 ($50k)

Current price: $65k. You want to sell.

FIFO Method

Sell Lot 1 (bought at $30k)

Gain: $35k taxable

Specific ID

Sell Lot 2 (bought at $60k)

Gain: $5k taxable

Savings: $30k less in taxable gains!

Frequently Asked Questions

When do I owe crypto taxes?

Taxable events include: selling crypto for fiat, trading crypto-to-crypto, using crypto to buy goods/services, and receiving crypto as income/payment. Non-taxable: buying and holding, transferring between your own wallets, gifts (up to limits).

What is tax-loss harvesting?

Selling assets at a loss to offset capital gains. If you have $10k in gains and $8k in losses, you only pay tax on $2k net gain. You can also deduct up to $3k in losses against ordinary income per year. Excess losses carry forward.

How does holding period affect taxes?

In the US: short-term gains (<1 year holding) taxed as ordinary income (up to 37%). Long-term gains (>1 year) taxed at preferential rates (0%, 15%, or 20%). Holding for 1+ years can save 17%+ on taxes.

Are DeFi activities taxable?

Yes, most DeFi activities are taxable: swaps (crypto-to-crypto trades), LP entry/exit (disposition), staking rewards (income when received), airdrops (income at fair market value), lending interest (income). Track everything.

Should I use FIFO or specific identification?

FIFO (First In First Out) is simpler but may not be optimal. Specific identification lets you choose which lots to sell—typically highest cost basis to minimize gains. Requires good record-keeping but can significantly reduce taxes.
