Understand How the Municipal Tax Works That Guarantees the Buyer Ownership and See Practical Examples of Calculation in Different Brazilian Cities

The Property Transfer Tax (ITBI) is one of the taxes that surprises those who buy a property. In addition to the price of the asset, notary fees, and financing, this municipal tax can represent up to 5% of the total transaction value, according to the rules of each city. Without it, the notary does not register the transfer, and the buyer does not officially become the owner, even after paying for the property.

History and Importance of the Tax

The ITBI gained strength after the Federal Constitution of 1988, which granted municipalities the authority to collect the tax on any onerous transfer of properties. Since then, its collection has become mandatory throughout the country. Therefore, the payment is not just a formality: it ensures the legal possession of the property.

Real estate law specialists explain that, without the payment of the ITBI, the deed is not executed, and the notary does not complete the registration. This requirement has been in effect since the 1990s and continues to be applied in all Brazilian cities.

How to Calculate the ITBI in Each Municipality

Calculating the ITBI is simple, but requires attention. The tax corresponds to a percentage applied to the property’s value, which varies between 2% and 5%, depending on local laws.

  • Example São Paulo: since 2023, the city hall applies a rate of 3%. A property worth R$ 500 thousand generates an ITBI of R$ 15 thousand.
  • Example Belo Horizonte: the rule follows the same pattern, with a rate of 3% set by municipal law.
  • Example Brasília: the Federal District uses 2%, which reduces the cost to R$ 10 thousand for a property worth R$ 500 thousand.
  • Example Porto Alegre: the capital of Rio Grande do Sul also charges 3%, according to the 2022 update.

Furthermore, the calculation base takes into account the greater value between the declared sale price and the market value set by the city hall, a criterion already adopted for IPTU since the 2000s.

Who is Responsible for the Payment

The most common rule in the Brazilian real estate market defines that the buyer must pay the ITBI. This happens because it is the buyer who acquires the right of ownership, and the tax serves to formalize the transfer at the notary.

The legislation, however, allows the buyer and seller to negotiate differently in the contract. Nevertheless, the established practice maintains the buyer as responsible. This interpretation, in effect since the 1980s, has been reinforced by courts and property registry offices.

In specific situations, exceptions arise. In the assignment of rights for properties under construction, those who assign these rights may bear the payment. Such cases must be clearly stated in the contract, according to guidelines from the National Justice Council (CNJ) issued in 2017.

Timing and Place of Payment

The ITBI must be paid before the public deed is executed or the contract is registered at the notary. Thus, the buyer presents the proof of payment and completes the transfer without obstacles. This practice, regulated by the National Tax Code since 1966, remains in effect today.

In Brazilian capitals, such as São Paulo, Rio de Janeiro, and Curitiba, the process occurs through electronic guides issued by the city hall. The deadline usually coincides with the signing of the deed, which avoids delays or blockages at the notary.

Exemptions and Exceptions Provided by Law

Although the ITBI is mandatory, some situations guarantee exemptions or reductions. Housing programs, such as My House My Life, created in 2009, offer discounts in several cities. Additionally, low-value properties may be exempt in certain municipalities, according to decrees published over the last decade.

These measures aim to encourage the formalization of property ownership among low-income families and expand access to legalized housing. Nevertheless, each city sets its own rules, and consulting the city hall before negotiations is essential.

In summary, ITBI ensures the formalization of property transfers in Brazil. Without payment, there is no registration at the notary, and the buyer does not acquire legal ownership. Therefore, knowing how to calculate, understanding the timing of payment, and knowing the rules of responsibility is essential to avoid issues in negotiations.

And you, have you included the ITBI in your planning before buying a property, or were you surprised at the final stage of the purchase?
