It will mean that “between 15,000 and 20,000” vehicle owners with license plates registered in December will have to pay the tax twice in three months or less — the first time by the last day of this year and the second time shortly after, at the beginning of 2026.
“This amount covers both cars that are in circulation and those that are still in showrooms waiting for a buyer, which are also subject to the tax,” explains Nuno Silva, president of the Portuguese Association of Automotive Trade, quoted by Jornal de Notícias.
The government's plans, which still need to receive the green light from Parliament, foresee that the IUC (Vehicle Tax) of up to 100 euros will be paid in one lump sum in February, while the tax above that amount can be divided into two instalments, to be paid by October.












So if I just paid in full in September 25, do I have to pay again in February or will it be collected in October next year and February 27??

This is not a help, but a pain. Those who owe more than €100 are given a payment reference number for only the first instalment. Anyone wanting to pay the full amount has to log on to the Finanças website to find the (different) payment reference number associated with paying in full. That number is usually not easy to find. It would be much easier if they allowed us to use the same payment reference number irrespective of whether we are paying just an instalment or the full amount.
It´s the same nonsense with IMI. The tax authorities shouldn´t be behaving as if everyone is destitute, and assume we´re all struggling to pay our way! If you can´t afford the IUC or IMI in one full annual payment, then you shouldn´t own a home or a car, it´s that simple.

So the title question remains unanswered. Do we pay twice or not? Knowing that our well funded and heeled government, who has been very succesful at taking money out of taxpayer's pockets is deciding this, it seems unescapable that we will pay twice.

The “paying twice” is referring to making one or two payments depending on the amount owed, not two full payments in one year - as written, the headline is a bit of click bait…
