Taxpayers in Aracaju who have received a notice from the Municipal Finance Department (Semfaz) concerning a discrepancy in their property's built area or number of floors have 30 days to challenge the information by opening a review proceeding. Each recipient must check how the deadline is calculated in their own notice rather than counting automatically from the news announcement. According to a municipal statement republished by Infonet on October 27, 2026, the registry change is not implemented during the challenge period; if no response is submitted by the deadline, Semfaz says the notified data will take effect.
Who is receiving the notice, and why?
Semfaz said it began mailing letters through the postal service on October 15, 2026, with deliveries reported from October 26. The notice concerns taxpayers whose properties are located in the municipality of Aracaju and whose municipal records show a possible discrepancy in built floor area or number of storeys. This does not mean every property owner in the city has received a notice.
The department attributes the discrepancies to an aerial survey conducted in 2022, which was used to compare properties' physical characteristics with their registered information. A difference identified by the survey prompted the administrative notice; recipients who disagree with the data may seek a review within the stated period.
How to challenge the property measurements within 30 days
- Read the entire letter. Check the property's identification, the stated built area or number of floors, the date and the response instructions.
- Check your individual deadline. The period is 30 days, but the public announcement does not set a single closing date for everyone. Follow the starting point specified in your notice; if anything is unclear, confirm it with Semfaz before the period expires.
- Request a review if you disagree. Semfaz says objections must be lodged by opening a review proceeding. The required documents are listed in the notice itself and are based on Aracaju's Municipal Tax Code.
- Confirm how to file. Before submitting documents, ask the official service channel how to lodge the request and which attachments are accepted. Keep a copy of the notice and proof of submission, if issued.
Document requirements: the public statement reviewed does not supply a universal checklist of attachments or confirm a dedicated online address for this particular challenge. Without the recipient's letter or an updated filing procedure, it would be misleading to present plans, deeds, photographs or any other documents as mandatory in every case. Check the applicable list in your notice and with the department.
What happens if the recipient does not reply?
According to Semfaz's statement, no registry change is implemented during the challenge period. If the deadline passes with no response from the taxpayer, the department says the registry update takes effect and that silence is treated as acceptance of the reported information. Recipients should therefore check the deadline on their letter, including when they believe the measurements are already correct.
Is the letter a 2027 IPTU property tax bill?
No. Semfaz has clarified that the mailed notice is not the 2027 IPTU property tax bill and should not be mistaken for a payment slip. It concerns the municipal property register. The department says updating the recorded built area may affect the property's taxation. However, the statement does not specify what any individual will pay, issue a personal charge or announce a date for any future assessment arising from the review.
Where to contact Semfaz in Aracaju
The department's in-person service is at Praça General Valadão, 341, Centro, Aracaju, Monday to Friday, 8 a.m. to 4 p.m. The published official telephone number is (79) 3179-1100. Its official website is fazenda.aracaju.se.gov.br. When seeking guidance, ask specifically how to challenge the discrepancy in your letter; do not assume that a general service listed on the website is the correct filing channel.
How to spot attempted fraud
Legitimate letters do not make every message claiming to come from the municipal finance authority authentic. In a warning published on October 21, 2026, Semfaz reiterated that it has no official WhatsApp number for customer service, collections or receipt of payments. Reports described callers posing as municipal finance personnel. The department advises people not to share personal or banking details, make transfers or open suspicious links. If contacted, stop the conversation and verify the matter directly through the official phone number or website.
