Our calculators are built with transparent formulas. Every calculator shows its formula breakdown and assumptions.
Some calculators are estimates because official rates may change or because we use simplified models. We clearly label these as estimates.
Simple estimates differ from official payroll/tax calculations. For example, our tax estimate does not replace LHDN's PCB calculator.
Rate files are versioned by effective year and last reviewed date. Every calculator shows when its rates were last reviewed.
KiraSmart prioritizes transparency by showing formulas and assumptions so you can understand how results are derived.
