How does the tax return work?


Preparation is a crucial step. We'll start with a consultation to understand your sources of income, potential deductions and investments. 

At this stage, we'll guide you through the documents and information you need to prepare your tax return correctly.


We prepare your tax return. This involves a detailed analysis of your documents and information, applying the appropriate tax codes, and maximizing available deductions and credits. We also ensure compliance with current tax laws. Once the return has been prepared, we'll present you with an outline for review and approval.


Once you've approved the declaration, we submit it on your behalf to the tax authorities. 

But our commitment doesn't stop there. We remain available to answer your questions, to help you in the event of any subsequent correspondence or inquiries from the tax authorities. 

We're here to support you all year round, not just during the tax season.
