How the PIT estimator works

The estimator applies progressive personal income tax brackets to annual taxable income. It is useful for fast planning, but it does not replace official tax computation, deductions, allowances or adviser review.

How the VAT and WHT estimator works

The estimator applies user-entered VAT and withholding percentages to a base amount. Use it to understand invoice impact quickly, then confirm payment type, VAT treatment and withholding position before filing or payment.

How the import duty estimator works

The duty estimator uses CIF value, user-entered duty rate and VAT rate to model a first-pass landed-cost scenario. It does not replace tariff classification, valuation or customs review.

How the wage lookup works

The wage lookup returns the published province wage stored in the portal data layer. Use it as a planning baseline, then confirm district notes, sector rules and effective date before relying on it operationally.

How the setup estimator works

The setup estimator totals user-entered registration, professional, premises and deposit assumptions. It is designed for internal budgeting rather than official cost confirmation.
