Is the Vehicle Circulation Tax (IUC) in Portugal set to rise in 2026? The short answer is: no, it's not. But here's where it gets a little more complicated. The IUC is an annual tax that all vehicle owners in Portugal must pay, and there's been some misinformation floating around that it's going up. Let's break it down. The IUC is changing in February 2026, when all vehicles will start paying the tax in the month they're registered, instead of the month they're purchased. This means some drivers will have to pay the IUC twice in a short period. But, according to the Portuguese government, the IUC rates won't be changing. That means the base values will stay the same. The government has also clarified that the IUC won't be increased for vehicles registered before or after 2007. So, what's the deal with the change in registration month? For vehicles registered before July 2007, the tax amount is determined by engine displacement and fuel type. For cars registered after that date, the calculation includes environmental factors like CO₂ emissions, year of registration, and fuel type, with higher tax rates for models with a greater environmental impact. This change is designed to encourage the purchase of more environmentally friendly vehicles. So, while the IUC isn't increasing, it's evolving to reflect a shift towards greener transportation. But here's where it gets controversial: some people might argue that the change in registration month could lead to a temporary increase in the tax for some drivers. However, the government has assured that the base values will remain the same, and the calculation method will stay consistent with last year's. In the end, it's important to stay informed and clear up any misinformation. The IUC is an important aspect of vehicle ownership in Portugal, and understanding the changes can help you plan accordingly. So, if you're a vehicle owner in Portugal, keep an eye on these changes and make sure you're aware of the new rules. And this is the part most people miss: the IUC is just one of many taxes and fees associated with vehicle ownership. There are also road tax, insurance, and maintenance costs to consider. So, while the IUC might not be increasing, it's still important to be mindful of the overall financial impact of owning a vehicle in Portugal. Do you think the change in registration month will have a significant impact on vehicle owners? Or is the government's clarification enough to put your mind at ease?
