Brazil’s Supreme Federal Court (STF) has ended degree tests for the autism tax benefit on vehicle purchases. The plenary decision came on 3 August 2026 and was unanimous.
Tax benefits cannot be restricted by the degree of autism or the severity of a mental disability.
Court Strikes Down Degree Limits
The STF struck down expressions that limited the benefit to severe or profound mental disability and moderate or serious autism. Justice Alexandre de Moraes was the rapporteur for the case.
The provision came from the tax reform regulation, Complementary Law 214/2025. Therefore, the court found those distinctions unconstitutional for this purpose.
What the Autism Tax Benefit Covers
The autism tax benefit is the zero rate of the IBS and the CBS on car sales to disabled and autistic people. Those are the two new consumption taxes.
These are the two new consumption taxes created by Brazil’s tax reform. Before the ruling, the zero rate applied only to severe or profound mental disability and moderate or serious autism.
As a result, level 1 autism and mild mental disability were excluded.
Clinical Criteria No Longer a Barrier
The court framed degree of disability as a clinical criterion, relevant to treatment but not a basis for restricting a tax benefit. In fact, it said the tax authority cannot exclude people on that ground alone.
Autistic people at level 1 support needs, and people with mild mental disability, can now apply for the zero rate. However, they must meet other legal requirements.
Level 1 Autism Explained
Level 1 in the autism support scale describes people who need some support. It is the lowest of three levels.
Previously, these individuals were not eligible for the autism tax benefit. Now, they can seek the zero rate on vehicle purchases.
No Automatic Exemption
The decision does not grant an automatic exemption. Each case is still assessed individually.
Applicants must provide proof of disability, follow rules on vehicle use or adaptation, and observe a waiting period between purchases. So, eligibility is not guaranteed.
Other Taxes Unchanged
The ruling does not change IPI, ICMS, IPVA, IOF, or income tax exemptions. Those have their own legislation and continue under their own criteria.
By contrast, the autism tax benefit specifically concerns the IBS and CBS zero rate. Therefore, other tax benefits remain unaffected.
Impact on Applicants
People with level 1 autism or mild mental disability can now apply for the autism tax benefit on vehicles. In addition, they must satisfy all other legal conditions.
The court’s decision removes the degree-based restriction. Still, each application is reviewed on its own merits.
Legal Basis and Context
The provision came from Complementary Law 214/2025, part of Brazil’s tax reform. The STF‘s ruling is a unanimous plenary decision.
Justice Alexandre de Moraes served as rapporteur. Meanwhile, the court emphasized that clinical criteria are not a basis for restricting tax benefits.
Practical Steps for Eligible Individuals
Eligible individuals must prove their disability and comply with vehicle use or adaptation rules. They also need to respect the waiting period between purchases.
Once these requirements are met, they can benefit from the zero rate on IBS and CBS. Overall, the ruling broadens access to the autism tax benefit.
