A common interface for calculating taxes across the world.

API

taxes.schema

This should export a valid JSON schema that defines the input values that the user should enter.

For example:

{
  title: 'Some country',
  type: 'object',
  required: [],
  properties: {
    grossSalary: {
      type: 'number',
      title: 'Base salary'
    },
    status: {
      type: 'string',
      title: 'Context',
      enum: [ 'single', 'married' ]
    }
  }
}

taxes.calculate(value, callback)

This should export a function that takes a value compliant with the schema and a callback(err, annualIncome) that is called after the calculations are made.

For example:

function (value, callback) {
  if (value.status === 'single') {
    return callback(null, value * 0.7)
  } else {
    return callback(null, value * 0.6)
  }
}
