To date, over 107,000 people have signed the petition - available here - "against the expected increase in IUC for cars prior to 07-2007".
"The purpose of this petition is to present an alternative suggestion, which we believe to be fairer and more coherent. Electric vehicles are currently exempt from paying IUC, as part of an effort to promote the energy transition. We recognise the importance of this transition, but we consider that should not serve as a pretext for all fiscal measures".
Therefore, those responsible for the petition propose that "electric vehicles start paying the IUC according to the power of their engines, eliminating the current exemption, and that they are not subject to the additional carbon tax that is applied to combustion vehicles".
"We believe this is the fairest and most equitable measure, which will not harm those who face significant financial difficulties and who do not even use these same highways. Often, these people are not seeking subsidies, they simply wish not to be further burdened by disproportionate tax burdens".
According to the report accompanying the OE2024 proposal, vehicles registered up to 2007 in "category A and E" will be covered.
Contacted by Notícias ao Minuto, a source from the Tax Authority (AT) clarified that, "according to the Single Circulation Tax Code, vehicles whose first registration date is before 1981 are not subject to IUC".
This means that the IUC will be increased for cars registered between 1981 and 2007.

So what is the message here, let's tax more those who can least afford to pay more tax? This is another hidden tax hidden under the guise of emissions, but targets those who can least afford to pay the tax. What is the goverment expecting, that these mostly low income earners can alternately choose to purchase a qualifying car to avoid the tax increase? If the goverment were serious about emissions reduction, they would provide an incentive to buyers of lower priced new cars or newer used cars. In fact if the government were really serious, they would reduce taxes (there are so many, it's not easy to list them all) for lower income earners. This in turn will offer better opportunities for this important group to stay in Portugal, instead of emigrating to other countries in the EU for higher salaries. The future in Portugal must be in eliminating emigration, and not be reliant upon immigration of foreigners. I will add my name to support the petition.

Instead of charging more tax on older cars ("to pay for reduced toll charges" - weird logic IMO) , the government should offer financial incentives for people to trade up to a newer car. The number of 'old' cars that I see on the roads in Portugal is alarming. Reducing their number will reduce pollution, increase safety on the roads, and boost the car market in Portugal. It will also help to encourage the investment in car charging points, since many people will consider electric vehicles as their upgrade choice. Penalising owners of older cars to pay for reduced toll charges is completely wrong in my opinion.

The same senseless comments from people on here. On the one hand, complaining that taxes are too high, on the other they want more subsidies (i.e. paid for via higher taxes) to encourage certain behaviour. You can't have it both ways. If you expect the government to provide everything for you, expect it to also take everything from you! That's how the failed Socialist model works that so many European countries are still clinging to.

The only incentive is increasing the tax for those very polluting cars. Otherwise there will be no incentive for people to buy newer cars. Most of those cars are using parking spots and are hardly used.
