Inverse income tax functions

inverse_income(tax, fy.year = "2012-13", zero.tax.income = c("maximum",
  "zero", "uniform", numeric(1)), ...)

Arguments

tax

The tax payable.

fy.year

The relevant financial year.

zero.tax.income

A character vector, ("maximum", "zero", "uniform", numeric(1)) Given that many incomes map to zero taxes, the income_tax function is not invertible there. As a consequence, the inverse function's value must be specified for tax = 0. "maximum" returns the maximum integer income one can have with a zero tax liability; "zero" returns zero for any tax of zero; "uniform" provides a random integer from zero to the maximum income with a zero tax. The value can also be specified explicitly.

...

Other arguments passed to income_tax. If tax or fy.year are vectors, these should be named vectors.

Value

The approximate taxable income given the tax payable for the financial year. See Details.
