The payment of the Single Circulation Tax (IUC) will change and there are already defined dates for the new rules to come into force, but not all drivers will benefit from the possibility of dividing the tax into several installments. There is a specific criterion that determines who can pay in three installments and who will have to continue paying in a more concentrated way.
The change was approved by Parliament and is part of a reformulation of the IUC collection model, which will have a fixed calendar throughout the year. Still, the application will be phased, with a transition period before full implementation.
According to the website, the new regime foresees that tax payments will be made in April, no longer depending on the vehicle registration date, as is currently the case.
A new tax calendar
The main change is in the way the tax will be organized throughout the year. Instead of scattered dates, the IUC will focus on specific moments, which aims to simplify the process for taxpayers.
According to the same source, this change follows a logic similar to that of IPTU, in which the number of installments depends on the amount to be paid. The objective is to reduce errors and delays, which have led to a high number of administrative offense cases.
The Government argues that the current model creates confusion and contributes to unintentional non-compliances, as many taxpayers end up not correctly tracking payment dates.
The detail that defines who can share
Although the possibility of paying in installments is one of the main new features, this will not be universal. It all depends on the tax amount.
According to Notícias ao Minuto, only taxpayers with IUC greater than 500 euros will be able to divide the payment into three installments, distributed over the months of April, July and October.
This detail ends up excluding a large proportion of vehicle owners, especially those with lower taxes, who will continue to be subject to more concentrated payments.
How are other taxpayers?
For smaller values, the model will be different. When the tax is equal to or less than R$100, payment will have to be made in a single installment, in the month of April.
In cases where the amount exceeds R$100, but does not reach R$500, the payment will be divided into two stages, with payment in April and October.
According to the same publication, this differentiation aims to balance administrative simplification with the financial capacity of taxpayers, avoiding higher tax burdens.
Missing a payment can be expensive
The new model also includes more demanding rules in case of non-compliance. Failure to pay an installment within the defined period has immediate consequences.
According to information provided by the same source, if an installment is not paid on time, the others become automatically due. In other words, the taxpayer loses the benefit of the installment payment.
This measure seeks to ensure greater rigor in compliance with tax obligations and avoid prolonged delays.
A period of transition before total change
Although the new rules have already been defined, their application will not be immediate. The year 2027 will act as an adaptation phase to the new model.
According to Notícias ao Minuto, this year payment will be made intermediary. For amounts up to R$500, the tax will be paid in a single installment in October.
In cases where the amount is higher, payment can be made in two installments, in the months of July and October, maintaining the possibility of full payment in advance.
When the new rules come into force
The full implementation of the new model is only scheduled for 2028. Until then, the current regime will continue, with payment in the month of registration.
According to the same source, this phased transition aims to avoid abrupt financial impacts and give taxpayers time to adapt to the new rules.
The reformulation of the IUC appears in a context of administrative simplification, but will have different effects according to the taxpayer’s profile.
While some may benefit from greater payment flexibility, others will continue to be subject to financial effort concentrated at a single moment.
Confirming the tax amount and understanding which bracket you fall into becomes essential to anticipate how and when you will have to comply with this tax obligation.
