What Is the CIB and Why Is It Being Implemented

Since 2025, Brazil has created the Brazilian Property Registration (CIB), a unique identifier for each property. This registration applies to both urban and rural properties.

It will function as a “CPF of the property.” The Sinter — National System for Territorial Information Management — will integrate the system.

This system consolidates land data used by federal, state, and municipal agencies. Thus, there will be greater integration and control over property records.

How This May Affect IPTU and the Calculation Base

Although the measure does not mandate an increase in rates, it promises to improve oversight. Experts highlight that transactions involving buying, selling, or renting are expected to become less informal.

As a result, the use of market values that are closer to reality is anticipated. The calculation will use the so-called ‘reference value’.

In summary, municipalities that use outdated assessed values may need to review their registrations. Consequently, there may be an increase in the IPTU calculation base.

More properties may end up paying higher taxes. This will occur in accordance with the new reference value.

Smaller cities, with limited technical infrastructure, are more impacted. There, assessed values are often outdated.

These municipalities will need to update the assessed value when using the CIB as a parameter. The goal is to bring records closer to the actual market value.

Additionally, there are complications with rural properties, plots, or transition areas. In these situations, determining the value can be more complex.

Experts warn that if there are no clear criteria, the risk increases. Taxpayers may end up paying more without adequate compensation.

What Changes in the IPTU Calculation and Implementation Timelines

Each municipality charges the IPTU annually based on the assessed value of the property. It applies to ownership, beneficial ownership, or possession.

The assessed value is estimated by the municipality according to local laws. Thus, each city maintains autonomy over this calculation.

According to lawyers and tax consultants, there are no changes in the rates. However, what defines the tax base of the property tax may be altered.

In other words, the tax burden may indirectly increase. This will happen if the assessed value is revised upwards.

The timeline indicates that the CIB was officially created in 2025. The implementation in capitals is expected for 2026.

The expansion to other municipalities should occur by 2027.

The Soviet Union spent 22 years drilling into the Earth’s crust and reached a depth of 12,262 meters — they found water where it was thought impossible, hydrogen bubbling from the rock, granite that is 2.7 billion years old, and temperatures of 180 degrees that melted the drill bits.
