Practical And Updated Guide To Report Rentals In The Carnê-Leão Web, Understand What Changes With CIB + Sinter And Which Receipts To Keep To Avoid Tax Problems.
The Federal Revenue published Normative Instruction 2.275, of August 15, 2025, putting the Brazilian Real Estate Registry (CIB) and integration with notaries and municipalities via Sinter into practice. The regulation was published in the Official Gazette on August 18 and took effect immediately after publication.
The goal is to unify data on deeds, registrations, and municipal records, allowing for automatic cross-referencing with the taxpayer’s declaration. This includes lease contracts and essential changes in properties.
In practice, those who receive rent have less room for informality, and those who pay rent need to accurately report their expenses in the annual declaration, under penalty of inconsistencies.

The government requests the Federal Revenue Service for a new system to automate the income tax declaration, reducing errors, time, and bureaucracy for millions of Brazilians.

What Changes With The CIB And Sinter In Rentals
The CIB creates a unique number for each property, connecting notaries and municipal records to Sinter. This data is now sent electronically and almost in real time, allowing the Revenue to track deeds and leases better.
The official Sinter page explains that the system integrates legal, tax, registry, and geospatial information on urban and rural properties, with participation from the Federal Government, States, and Municipalities. This provides technical backing for the new cross-referencing.
This advancement also reaches the citizen, as there is already a public service to consult properties in Sinter, searching by CIB, address, and other identifiers. The trend is for rental inconsistencies to appear more quickly.
Who Should Use The Carnê-Leão Web To Declare And Where To Access It
Those who receive income such as rent from individuals (or from abroad) should fill out the Carnê-Leão, monthly calculating the owed tax and issuing the DARF. Access is through e-CAC, in the “Calculate Carnê-Leão” service.
The Carnê-Leão Manual details annual calendar configurations and filling out, including when income comes from rent, covering fields for applicable exclusions/deductions.
Beyond the CIB, there are other cross-referencing sources. Industry companies send DIMOB with information on leasing and brokerage, strengthening the coherence between what the lessor declares and what the market reports.
Step By Step To Report Rent In The Carnê-Leão Web
- Log Into the e-CAC and open “Calculate Carnê-Leão”. Set up the calendar year and profile. The official manual teaches this initial step.
- In Income, record the rent received in the month. If there is co-ownership, each owner registers their share according to the contract.
- In Payments/Cash Book, report expenses necessary for income perception and the maintenance of the source, when paid by the lessor. In practice, the calculation considers the net amount of the rent, and reference materials indicate condominium and IPTU as items commonly deducted when paid by the owner. Keep the receipts.
- Generate the DARF for the month and pay within the legal deadline. The official service allows you to generate the document and, in the following year, import the Carnê-Leão data into the DIRPF.
Receipts That The Revenue Crosses Now
With CIB + Sinter, records from notaries and municipalities feed the federal base, making it easier to verify if a contract is active and if there is coherence with the Taxable Income of the lessor.
Keep contracts and addenda, rent receipts, bank statements, condominium invoices, and IPTU when paid by the owner, as well as the settled DARFs from the Carnê-Leão. This supports the documentary narrative in case of doubt.
For the formal market, the DIMOB from property managers and real estate agencies is an additional data vector that can indicate discrepancies in values and involved parties.
Deadlines, Fines, And How To Regularize Late Payments
The Carnê-Leão is monthly. Accumulating and leaving everything to be adjusted in the annual declaration increases the risk of tax issues, especially now, with the reinforcement of Sinter.
If there is a delay, issue a DARF with updates and settle the debt before submitting the DIRPF. The official environment guides the calculation and import of data for the annual declaration.
The golden rule is consistency: received amounts, proven deductions, and contracts compatible with what public databases display after the adoption of the CIB.
For Renters, How To Report Rent Paid In The DIRPF
Those who pay rent should report the amount in the Payments Made section, code 70 – Rentals of real estate, providing the CPF or CNPJ of the lessor and the total paid in the year. Various reference guides and economic coverage reinforce this procedure.
Important: rent paid is not deductible for individuals, but reporting it helps close the cross-reference with what the lessor declares and avoids inconsistencies. Keep receipts, transfer proofs, and contracts. With the advancement of Sinter, omissions tend to appear more quickly.
And what do you think, will the automatic cross-referencing between CIB and Sinter really end the shortcuts in rent or will it only increase pressure and the risk of tax issues for lessors and renters? Share your opinion in the comments.
