The regular deadline is March 31 of the following year. With an extension, you can push this to September 30. We automatically request an extension for all our clients.

How much does a professional tax return cost?
Costs depend on the complexity of your tax situation. Simple tax returns take just a few hours, while complex cases with international ties or corporate investments require more effort. However, the tax savings usually far exceed our fees.
What documents do I need?
Typical documents include your salary certificate, bank statements, insurance policies, receipts for professional expenses, donation receipts, mortgage interest statements, and pension certificates. We will send you a complete checklist.
What is the difference between withholding tax and regular assessment?
Withholding tax is deducted directly from your salary. With a regular assessment, you file a tax return. The regular assessment allows significantly more deductions and is usually cheaper.
