The general idea behind some of the allowances and deductions are that people should only pay tax on disposable income. You are, for example, entitled to deduct expenses if you:
- Travel more than 12 kilometres in each direction between your home and work.
- Pay a membership fee to a trade union and/or an unemployment insurance fund.
- Make payments to a private pension scheme.
- Pay interests expenses.
