ABOUT US
If you are thinking of expanding your business into North America, you need a strong partner at your side to help you set up your company, manage your finances and master your taxes. We are your bridge to navigating the financial, tax and business landscape of North America and pride ourselves on providing services tailored to our clients' needs.
The Massat Group has been serving international companies in a variety of industries since 1986. Our strength lies in guiding our clients in structuring and growing their overseas operations. Specifically, we act as a link between parent companies and subsidiaries in the areas of financial reporting, tax services and management consulting.
Massat Hoyer Consulting is our response to the increasing pace of change in US sales tax regulations. The Wayfair decision in 06/2018 introduced the system of economic nexus, which enormously increased the complexity of sales and use tax management. Since then, most states have introduced new sales and use tax obligations, also known as nexus. However, no two states' nexus laws are the same, resulting in more than 13,000 different sales tax jurisdictions for remote sellers.
Very good knowledge of the host country language is no longer sufficient today. You must have a good understanding of local habits and go beyond cultural gaps that may exist between business actors of different backgrounds.
