The Aalbers Standard

We operate where standard solutions are insufficient. By combining experience from both the tax authorities and private advisory, we provide a distinct understanding of how regulations are applied in practice. Every engagement is handled directly at the partner level, ensuring absolute accountability and discretion.

The questions that reach us usually arrive at a decision point. A company is about to buy property and its structure is not yet fixed. A client is considering a move to the island and wants to know whether the penshonado regime is within reach. A supply chain runs through several entities and turnover tax accumulates at every step. An assessment has been received and the choice is between accepting it and objecting.

The general rules behind those questions are set out in Doing Business in Sint Maarten: A Tax Guide and in Objecting to a Sint Maarten Tax Assessment. What they mean for a particular position takes a conversation.

Who We Advise

Entrepreneurs and Companies

We advise companies on Sint Maarten on profit tax, turnover tax, wage tax and social security premiums. Typical questions concern the structure of a group, the tax position of a new venture and the response to an audit by the Tax Administration.

Property Owners and Investors

Many of our clients own property on the island and live in the United States, Canada or Europe. We advise on rental income, room tax and turnover tax, transfer tax on a purchase, and on holding property in your own name, through a company or through a private fund foundation.

Moving to or Leaving Sint Maarten

Clients who plan to settle on the island want to know how their pension and investment income will be taxed and whether the penshonado regime applies to them. Clients who leave need to deregister properly and settle their position with the Tax Administration. We guide both.

Disputes With the Tax Administration

An assessment, a writ of execution or an audit report calls for a timely and well-founded response. We draft objections and appeals, arrange payment plans with the Receiver and represent clients before the Court of First Instance. The deadlines are explained in Objecting to a Sint Maarten Tax Assessment.

Experience From Both Sides of the Table
