When you do your income tax return, all possible deductions are discussed. To prevent you from paying too much tax, it is wise to check well all that you might be entitled to. But beware: you should always be able to provide proof of your costs. We therefore recommend that you efficiently organize your paperwork and documentation all year round. You are needing some support for doing this? BAS can come to the rescue!

Healthcare Costs

One of the most important kinds of deductions are health care costs. Therefore, make sure that you keep an overview and know which of your care costs are deductible. Unsure about which costs? Contact BAS!


Do you have children? The costs associated with the care and maintenance of your children’s (under 21) lives might be deductible. Additionally, f you meet certain conditions, you might have a right to the income-related combination tax. Want to know more? Please contact us at BAS!


When you have an owner-occupied home, this affects the level of income tax you pay. Often there are tax deductions such as interest rates and costs associated with your home, including the so-called “notional” rental value. This is an additional burden on owners. The amount of this fee is dependent on the property tax value of your home.

But there are more deductions… Are you studying? If so, you can deduct the cost of your study materials from a portion of your taxes. Download our checklist and discover your advantages!

May 1, an important date!

The declaration of your income for 2021 must be filed with the tax authorities by May 1, 2022.
If unsuccessful? Request to delay. You can get an extension to September 1 to submit your tax return. Is this still not enough time? Then turn to us for help. We can even delay applications until May 1, 2023. Please contact us at BAS.
