ABOUT THIS TOOL
How the provisional refund calculator works
What it estimates
The monthly amount you could receive in advance for mortgage interest relief, through a provisional assessment (voorlopige aanslag).
How to read the result
Your deductible balance is the mortgage interest minus the eigenwoningforfait. That balance is relieved at a capped rate and paid in twelve instalments.
Who it's for
Homeowners with a mortgage on their own home who would rather get their tax relief monthly than in one go after filing.
Good to know
A provisional refund is an advance. The final amount is settled when you file your income tax return for the year.
Provisional refund questions
