Following the publication of Decree-Law no.  92/2018, a new legal framework aimed at maritime shipping and merchant fleets has been introduced. With the goal of reinforcing the competitiveness of the Portuguese flag across the seas, it is established a new special regime for the computation of the taxable income based on the vessels’ tonnage (tonnage tax), as well as a special tax and contributory regime for the seafarers. The legal changes are supplemented with a revamped and simplified registration for ships and vessels.
