Size is not wealth, and the court has now said so in a ruling every Brazilian municipality has to follow.

Brazil’s Supreme Court has ruled that a city cannot charge a higher property tax rate simply because a building is large. If you own property in Brazil, this is the kind of decision that changes a bill.

What the court actually decided

The thesis is one sentence: it is unconstitutional for a municipal law passed after Amendment 29 of 2000 to fix the IPTU rate on the basis of the area of the property.

IPTU is Brazil’s municipal property tax. Amendment 29 let cities charge progressive rates, but it named the grounds: the value of the property, where it is, and what it is used for.

Floor area is not on that list. Chapecó argued that a bigger building means more intensive use of the land and therefore justifies a higher rate. The court rejected that.

The reasoning is straightforward. Area is a proxy for wealth, and the Constitution already provides a direct measure of wealth — the assessed value. A city that wants to tax wealth should tax the value.

The rule that started it

Chapecó, a city of about 250,000 in Santa Catarina, passed Complementary Municipal Law 639 in 2018.

It set the IPTU rate at 1% for properties with a built area of 400 square metres or more. Smaller properties paid less.

A taxpayer challenged it, the lower court ordered the rate cut to 0.5% with a refund, and the case travelled up to the Supreme Court, where it was given general repercussion — the status Brazil uses when a ruling should bind every court in the country.

That is why a dispute over one city’s tax table now governs municipal taxation nationwide.

What cities can still do

Quite a lot. Progressive rates by assessed value remain lawful, which is the main tool most municipalities use anyway.

So do different rates by location, which is how cities charge more in central districts, and by use, which is how they separate residential from commercial.

What is gone is the shortcut: a flat rule that says anything over a certain number of square metres pays a higher rate.

Whether you can get money back

Be careful here, because this is where reporting tends to overreach.

In the Chapecó case itself the lower court had already ordered the rate corrected to 0.5% and the overpayment refunded. That is the specific case.

We found no modulation of effects in the Supreme Court decision — nothing limiting how far back it reaches. But that is not the same as a national refund entitlement, and Chapecó has said the decision is not yet final for it.

If you are paying an area-based IPTU rate somewhere, the ruling is binding guidance for every court in the country. Whether you recover past payments is a question for a lawyer and your municipality, not for a headline.

Why it matters if you own property here

General repercussion means the thesis binds every court in Brazil. Municipalities with area-based rules will have to rewrite them.

For foreign owners the practical point is narrower and more useful: check which criterion your IPTU rate is actually set by. If the answer is square metres rather than assessed value, the rule behind your bill is now unconstitutional.

It also tells you something about how Brazilian property taxation works. The country taxes value, location and use, and the Supreme Court has just refused to let cities add a fourth criterion by the back door.

Frequently Asked Questions

What did the Supreme Court decide?

That a municipal law passed after Constitutional Amendment 29 of 2000 cannot set the IPTU property tax rate according to the area of a property. The decision was unanimous, concluded on 5 August 2026, with Justice Dias Toffoli as rapporteur.

Can cities still charge different rates?

Yes. Rates can still vary by the assessed value of the property, by location and by use. Those are the three grounds the 2000 amendment authorised. Floor area is not one of them.

Can I get a refund?

In the Chapecó case the lower court ordered the rate corrected and the overpayment refunded. There is no reported modulation limiting how far back the ruling reaches, but that is not a general national entitlement — it depends on your municipality and your own case.

Does this apply everywhere in Brazil?

The thesis carries general repercussion, so it binds every court in the country. Chapecó has said the decision has not yet become final in its own case.
