Example Response

A tax calculation for a Brazilian employee earning R$10,000/month: 
{
  "payeeId": "123e4567-e89b-12d3-a456-426614174000",
  "grossAmount": { "amount": 1000000, "currency": "BRL" },
  "netAmount": { "amount": 761244, "currency": "BRL" },
  "deductions": [
    {
      "name": "INSS (Instituto Nacional do Seguro Social)",
      "amount": { "amount": 82839, "currency": "BRL" }
    },
    {
      "name": "IRRF (Imposto de Renda Retido na Fonte)",
      "amount": { "amount": 155917, "currency": "BRL" }
    }
  ],
  "employerContributions": [
    {
      "name": "FGTS (Fundo de Garantia do Tempo de Serviço)",
      "amount": { "amount": 80000, "currency": "BRL" }
    }
  ]
}
The response includes employee deductions, employer contributions, and an optional summary field with step-by-step calculation details for each line item.
Amounts are in the lowest denomination of the currency. For BRL, 1000000 = R$10,000.00.
