Since the 1st of January 2019, there are new tax rules for sea-going vessels. To benefit from a VAT zero rate, vessels must issue a declaration that it is used for at least 70% outside national territorial waters.


The 70% rule can be determined by the distance traveled, the routes or the time spent outside territorial waters. As Marine Regions provides a global map of territorial waters, this layer (among others) can be used as input for the calculation of the tax rate.

Marine Regions

Marine Regions is a standard list of marine georeferenced place names and areas. It integrates and serves geographic information from the VLIMAR Gazetteer and the MARBOUND database. The purpose of Marine Regions is therefore to create a standard, relational list of geographic names, coupled with information and maps of the geographic location of these features. This will improve access and clarity of the different geographic, marine names such as seas, sandbanks, ridges and bays and display univocally the boundaries of marine biogeographic or managerial marine areas.
