Emigration to The Netherlands, buying or selling a house, changing your mortgage or switching to another mortgage provider, these are examples of ‘fiscal moments’ that impact your tax return in The Netherlands considerably.

With The TaxSavers, we investigate what you need to file your tax return properly, and involve you in the process, that you can do it yourself in the future.

During the process of preparing your tax return we will require your (online – DigiD) authorization to check which details the Belastingdienst has about you. We remain in frequent and close contact with you so we don’t miss any details.

Together we follow the tax return roadmap, a step by step process in completing your tax return which eventually is submitted to the Belastingdienst.


Before the tax return is submitted, we personally discuss the ins and outs of the fiscal process, so you are well-equipped, to complete it yourself in the following years. Upon your approval, the tax return is submitted to the Belastingdienst. Our service includes a check of the provisional tax assessment (voorlopige aanslag) that the Belastingdienst sends, for the coming year.

It’s a comfortable feeling when your tax return has been discussed, checked and submitted to the Belastingdienst. A few months later, you will receive a final tax assessment from the authorities, which we will also review.

Our Services

Tax Return

Your tax return for the current or even previous years, are completed, checked, and submitted to the Belastingdienst. Even the final tax assessment will be checked. Comfort with expertise.

Tax Assessment

Have you paid interest on your mortgage, healthcare costs, or any other tax-deductible expenses? We are up to date on which expenses are deductible, and can file a provisional tax assessment for you.

Double Check

Have you completed and filed your own tax return, but still not quite sure if you have missed anything? We can double-check this for you, and let you know if, and what you have missed. We will give you pointers on what you should take into account when filing for future years. It can save you time and money.


Immigration or emigration? If you have moved to or from The Netherlands you need to file a special tax return, the so-called M-form. We can help you prepare and file your M-form.
