Singapore tax & payroll calculator guide

Use the calculators for planning, then confirm current rates, allowances, contribution rules, and effective dates with the official authority. Calculum uses the numbers you enter; it does not reproduce Singapore tax law.

What materially changes

Rules to separate in a Singapore estimate

  • Resident income tax is generally assessed annually rather than reproduced by a universal salary-withholding rate.
  • CPF contributions can affect employee take-home pay and employer cost, with eligibility and rates depending on circumstances.
  • Public prices from GST-registered businesses are generally GST-inclusive, subject to specific exceptions.
