Calculadora de Impostos Cripto: Guia IRPF para Brasileiros

Como Calcular Manualmente

Step-by-Step

1. Export all transactions — From Gate.io e other exchanges
2. Organize por mês — Group transactions por calendar month
3. Calculate gains — Sale price - purchase price (FIFO method)
4. Calculate losses — Losses can offset gains
5. Net monthly gain — If > R$ 35.000, tax é 15% on net gain
6. Declare — No Programa IRPF 2024

FIFO Method Example

Buy history:

• Jan: 1 BTC @ R$ 150.000
• Mar: 1 BTC @ R$ 180.000

Sale in May: 1.5 BTC @ R$ 200.000

FIFO calculation:

• First BTC sold: R$ 200.000 - R$ 150.000 = R$ 50.000 gain
• 0.5 BTC sold: R$ 100.000 - R$ 90.000 = R$ 10.000 gain
• Total gain: R$ 60.000
• Tax (if net > R$ 35.000/mês): R$ 60.000 × 15% = R$ 9.000

Crypto-to-Crypto Trades

Exchanging ETH para BTC is taxable:

• ETH sold at market value em BRL
• BTC bought at market value em BRL
• Gain = ETH sale value - ETH purchase cost

DeFi Income

• Staking rewards — Taxable como income when received
• Yield farming — Token rewards taxable when received
• Lending interest — Taxable como income
• Airdrops — Taxable at market value when received
