Cross-border business owners




Are you a cross-border worker or a cross-border business owner, living in Belgium, Germany, or the Netherlands? Are you planning to emigrate or immigrate? Then you need to be aware that, as a cross-border worker, you will have dealings with the Belgian, German, and Dutch tax authorities. You have to take account of various laws and regulations relating to taxation and social security. How do you avoid paying tax twice? What about your mortgage interest deduction, child allowance, and tax credits? Where do you need to arrange social security? What do you have to do if you’re going to work abroad? Consilio has the answers to all your questions. Our specialists will advise you on all cross-border aspects, to ensure that you don’t end up paying unnecessary tax.

To assure you of the best advice if you are a cross-border worker between the Netherlands and Belgium or the Netherlands and Germany, we work very closely with Certafin Accountancy and Financial Management, based in Genk, and Jörg Reimer Steuerberatungsgesellschaft mbh based in Aachen. .

My rock and ally for all my business-related tax matters

Chiefly as regards my own business, but also for businesses and business owners I advise to operate over the border. In this sense too, Consilio is of great help to entrepreneurs and, specifically, to my business contacts

Extremely knowledgeable

To my mind, a tax professional must like nothing better than searching for and, more importantly, finding the most tax-efficient and financially beneficial set-up for me (and my business). Kind of a tax geek, who is extremely knowledgeable about all the legislation and who has a real flair for balancing the business and the personal side of taxation. All of which adds up to tax advice that puts a smile on your face, because it works, it's feasible, and it's appropriate. Marcel does all that.

Short lines of communication, expertise, and a progressive attitude

As an experienced national and international entrepreneur, I recommend Consilio's practical, transparent and budget-friendly approach to every potential client, whether they are start-ups or well-known and established business, in any discipline. Short lines of communication, expertise in and access to many subjects and related areas, with a far-sighted and progressive attitude rather than the traditional retrospective view.

Personal attention and knowledge

We’ve worked with Consilio for more than 10 years, because of the personal attention we get and their knowledge of the financial and tax issues that are relevant to us.

Billing and bookkeeping in one, it's perfect

As a newly-established entrepreneur, I can both sort out my bookkeeping electronically and use the Consilio system to bill my customers. Admin takes up very little of my time, and I quickly get an answer to any questions. It's great!
