The main change in the new IUC law is that the tax will no longer be paid in the month of vehicle registration em vigor a partir de 2027.
The Single Circulation Tax (IUC), popularly known as the "car stamp", is about to undergo significant changes as announced by the government. These new rules are part of the Agenda for Tax Simplification and seek to make the IUC payment process more accessible and less bureaucratic for taxpayers.
New IUC rules
The main change is that the IUC will no longer be paid in the month of vehicle registration. Instead, the deadline para a liquidação do imposto será até abril, para valores a pagar igual ou inferior a 100€.
If the IUC exceeds 100 euros será pago em two instalments, em abril e em outubro, com objetivo de proporcionar uma maior flexibilidade aos contribuintes.
