Which form should I send between 100 and 163?
You must choose Form 100 if, for example:
- Your household's taxable income is more than €100,000
- Some of your income is not subject to withholding tax. E.g. rental income, ...
- You own your own home and have mortgage interest to deduct
- Non-residents/frontier residents: you have special expenses (insurance, ...) or extraordinary fees to deduct
If none of these cases fit your situation and the Tax Administration has not specifically asked you to return Form 100, then choose Form 163
