Gross income is only the first line
A salaries tax estimate starts with employment income, but final liability depends on deductions, allowances and the comparison method. This is why a one-field salary tax calculator can be misleading.
Deductions come before allowances
Employment expenses, eligible self-education expenses, approved donations and MPF-related deductions can reduce net income when applicable. The calculator keeps each input visible for transparency.
Allowances reduce chargeable income
Basic, married-person, child, single-parent and dependant allowances can reduce net chargeable income. Entering the wrong allowance can create a wrong estimate, so the page treats them as user-controlled assumptions.
Progressive bands are marginal
When income moves into a higher progressive band, only the slice inside that band is taxed at the higher rate. The calculator shows a band breakdown so users can see which part of income creates the tax.
The standard-rate comparison matters
For higher-income users, the standard-rate result can be lower than progressive tax after allowances. Showing both methods improves trust because users can see why the selected tax result was chosen.
Provisional tax is not a deduction from income
Tax already paid is compared after estimated tax is calculated. It helps estimate refund or balance due, but it does not reduce employment income like a deduction.
