Prepare household and municipal inputs for Belgian income tax
Federal tax and a municipal surcharge
The Belgian tool distinguishes its federal calculation from the municipal surcharge. Confirm the local input for the municipality represented instead of borrowing a percentage from another address. Keep the tax year and the income basis consistent when comparing households or locations. The estimate does not determine the municipality from a postal address or replace a local assessment.
Household choices affect the comparison
The form includes personal allowances, children, marital-quotient options and selected reductions. These inputs describe a particular household case; they are not interchangeable ways to lower the result. Gather the relevant income and family information without mixing the figures of different people. When testing an alternative, change one assumption at a time and preserve the calculation breakdown so that the effect remains understandable.
