New Real Estate Registration Creates Unique Identification for Each Property in the Country, Expands Data Cross-Referencing Between Federal, State, and Local Governments, and Promises to Strengthen Oversight on Undeclared Operations, Including Rental Contracts.
The Federal Revenue Service has begun to establish a more efficient enforcement against undeclared rentals with the implementation of the Brazilian Real Estate Registry (CIB).
Provided for in the Complementary Law 214/2025, the unique identifier for properties will be used together with CPF and CNPJ to standardize registrations and cross-reference information between government levels, notaries, and tax systems.
The measure was detailed by the Normative Instruction RFB No. 2,275, of August 15, 2025, which establishes how notarial and registration services must report real estate transactions to the public authorities.

What Changes with the CIB in Rental Oversight
According to Harrisson Barboza de Holanda, in his column on the Portal Migalhas, the CIB inaugurates a new stage of asset traceability: “each property will have a national number,” which will be incorporated into documents, titles, and registry bases of the Federal Government, States, Federal District, and municipalities.
As he explained, this standardization facilitates the simultaneous sharing of data and, consequently, speeds up the verification of operations and the detection of discrepancies.
According to the author, the flow of information will be updated with each action taken in the notary office, from buying and selling to donation, including amendments and registrations.
He highlighted that integration with the Sinter (National System of Territorial Information Management) is a key element of this mechanism, as Sinter serves as the base that connects registries and attributes of properties for use by tax administrations.
As he emphasized, this infrastructure “optimizes and facilitates tax oversight”, including the new IBS and CBS, foreseen for the transition of tax reform.
Legal Basis and Implementation of the Registration
The LC 214/2025 consolidated the architecture of the consumption reform and determined the creation of the CIB for interoperability of registrations and efficient management of the IBS and CBS.
The article 59 provides for the integration of information between tax administrations, establishing grounds for the exchange of property data.
In addition, the IN RFB 2,275/2025 regulates the adoption of the CIB by notaries and public registries, describes obligations for electronic sharing via Sinter, and sets operational parameters for the continuous updating of the database.
Practically, as Harrisson Barboza de Holanda pointed out, “for each real estate transaction, the data will be transmitted” to federal, state, district, and municipal tax administrations.
He further noted that the standardization is likely to make the questioning of declared values and the verification of simulated operations, such as masked donations of sale and purchase, which historically required time and scattered diligence for verification, more expedient.
Possible Cross-Referencing to Detect Omitted Rentals
As the columnist highlighted, each property becomes inseparable from a national code, which expands the range of cross-referencing.
Among the examples cited, he mentions the capture of all properties linked to the same person by CIB and the matching of addresses reported by third parties in Income Tax Returns, a scenario that may suggest unformalized rental contracts before the tax authorities.
On the other hand, the correlation between asset transactions and declared income helps to highlight inconsistencies that previously went unnoticed.
Additionally, integration with Sinter allows consolidating the characteristics of the asset, transaction history, and registration links.
In practical terms, the public authorities can verify, with greater precision, whether rent is being received without the corresponding entry in the IRPF or IRPJ, as the case may be.
According to him, the combination of CIB + CPF/CNPJ + Sinter raises the level of transparency and reduces the gray area in which rents could circulate off the radar.
Risks to the Taxpayer Who Does Not Declare Rent
When the Federal Revenue identifies signs of undeclared rentals, the taxpayer may face penalty for the tax due, along with fines and interest.
As Harrisson Barboza de Holanda points out, the requirement typically covers the five years prior to detection, considering applicable decadential and prescriptive periods.
He also noted that one of the most severe aspects is the eventual configuration of tax evasion, in which case, in addition to the tax liability, there may be criminal responsibility.
How to Consult the CIB and Confirm the Property’s Linkage
The CIB number can be checked in the Federal Revenue environment and in interfaces integrated with Sinter.
The public consultation allows locating properties by map or by filters such as CIB, address, and reference codes (for example, INCRA), facilitating the verification of ownership and essential attributes of the asset.
For owners and tenants, verifying the code is a simple step to regularize registrations and avoid inconsistencies.
“The Brazilian real estate registration can be consulted on the website of the Federal Revenue of Brazil,” emphasized Harrisson Barboza de Holanda in the Portal Migalhas.
While guiding the consultation and storage of the number, he stressed that registration consistency is an ally of tax compliance and tends to mitigate risks of future questioning.
Why the CIB Accelerates Intelligent Cross-Referencing
Meanwhile, the Federal Revenue emphasizes that the CIB functions as a pillar of legal security for owners, buyers, and sellers, and as a technological basis for the implementation of a dual VAT starting in 2027.
This same infrastructure, in turn, facilitates automated analyses regarding the life cycle of the property, from registration to rental, with national data standards.
The expected outcome is a more efficient oversight and a reduction of disputes resulting from conflicting information.
Transparency and Document Organization
For those who rent or intend to rent a property, the guidance is straightforward: formalize contracts, register receipts, and declare income correctly.
Additionally, keep proof of payment, receipts, income statements, and CIB data organized.
In the case of legal entities, it is wise to review internal rental policies, update registrations, and align accounting systems to reflect the new identifier in documents and controls.
Finally, as Harrisson Barboza de Holanda emphasized, the combination of a unique identifier per property with the ability to cross-reference between CPF and CNPJ significantly reduces the margin for omission of rentals.
In his words, the CIB “makes it more effective to discover undeclared operations”, which tends to put an end to cycles of informality and promote tax compliance in the rental market.
