Philipsburg – On Thursday, November 12, 2026, more than twenty tax advisors took part in a hybrid demonstration of the Sint Maarten Tax Administration’s new online business tax portal. Organized by the Transformation Tax Administration (TTA) team in collaboration with Computech, the company responsible for its development, the session allowed participants to explore the platform and share feedback ahead of its expected launch in the second half of January 2027.
The new platform will expand the digital services available to businesses, providing additional ways to manage their tax obligations online. While Turnover Tax and Wage Tax declarations can already be submitted through the existing portal, the new platform will build on these services by introducing online filing for Car Rental Tax, Room Tax, and Timeshare Tax in January 2027.
Additional functionalities will be introduced throughout the year, including online filing of Profit Tax declarations and collective wage statements, access to historical tax filing and payment records, an overview of outstanding tax assessments and payment obligations, and a dedicated digital inbox for communication with the Tax Administration.
Businesses will also be able to review their filing and payment history, identify discrepancies, and upload supporting documentation when declarations or payments are not correctly reflected in the Tax Administration’s records. The submitted information will be reviewed and processed to improve the accuracy of taxpayer records, helping to reduce the need for unnecessary tax assessments and subsequent objection procedures.
The demonstration was well received, with tax advisors sharing questions, observations, and suggestions for further improvements. Their feedback will be taken into consideration as development of the portal continues.
Alongside the business tax portal, preparations are also underway to introduce online filing for Personal Income Tax. Following the successful completion of a pilot project for 2025 income tax returns, the Tax Administration is preparing to introduce online filing for the 2026 tax year in 2027.
Over the coming months, the Tax Administration will continue developing and testing new digital services. Businesses, tax advisors, and individual taxpayers will be kept informed about available functionalities and practical arrangements ahead of the respective launches.
