Methodology
How this calculator works
The calculator starts with Qatar-source revenue minus deductible expenses, adds disallowed expenses, subtracts loss carry-forward used, then applies the taxable share after a user-entered exempt ownership percentage. It estimates income tax at 10% for standard business planning or 35% for oil and petrochemical scenario planning. It separately estimates 5% withholding tax on selected payments to non-residents and clearly flags that Qatar has not applied VAT.
