If you need to deal with Aracaju's IPTU now, in 2026, the first precaution is to separate the beginning-of-year campaign from the services that remain available throughout the tax year. For checking debts and issuing payment slips, the municipal channel indicated by City Hall is the Portal do Contribuinte of the Municipal Finance Secretariat (Semfaz), at fazenda.aracaju.se.gov.br. The 7.5% discount for a single payment was temporary and ended on February 6, 2026, after an extension.
What is Aracaju's official IPTU portal
The direct address of the Portal do Contribuinte is fazenda.aracaju.se.gov.br. There is also a safe route through the City Hall homepage at aracaju.se.gov.br: in the featured services area, the "Portal do Contribuinte" link points to the Semfaz domain. This route is useful when search results show ads, old pages or third-party results.
In March 2026, City Hall began a new phase of portal modernization. The homepage gained an area for the most-used services, simpler wording and progressive adaptation for mobile phones. For that reason, a screenshot or tutorial from previous years may not show exactly the same buttons seen today. The most reliable criterion is the official address, not the appearance of the screen.
CEAC also maintains service pages that direct users to Aracaju City Hall functions, including debt inquiries and duplicate IPTU bills. This does not change the entry point for the municipal tax service: to issue or check a payment slip, prefer Semfaz's Portal do Contribuinte. AjuInteligente is another official municipal system used for various requests and protocols, but the specific 2026 IPTU guidance directs bill issuance to the Portal do Contribuinte.
How to issue a duplicate 2026 IPTU bill
Go to fazenda.aracaju.se.gov.br and look for the service related to IPTU, payment booklet issuance or debt inquiry. Because the portal is being modernized, the name and position of the shortcut may change without the service ceasing to be official.
Have the property's details at hand. In Semfaz's own guidance on issuing IPTU documents, the property registration number is one of the pieces of information used to locate the record; in
recent versions of the service, taxpayer identification may also be required. After the inquiry, check that the selected tax year is 2026, that the property matches the expected record and that the document shows the installment or debt you intend to pay.
At the beginning of 2026, City Hall asked taxpayers to issue a new single-payment bill if they wanted to use the discount after the deadline was extended. That guidance was tied to the January and February campaign and does not mean that duplicate bill issuance is restricted to that period. The Portal do Contribuinte remains the official channel for checking debts and generating municipal collection documents.
How to check the 2026 IPTU installments
Municipal Decree No. 8,429, dated December 22, 2025, established the original 2026 IPTU calendar. Installments were scheduled for February 6, March 6, April 8, May 8, June 8, July 7, August 7, September 8, October 7 and November 9, 2026. The single-payment due date had initially been set for January 16, but City Hall extended payment with a 7.5% discount through February 6.
As of August 28, 2026, therefore, the first seven installments on the calendar had already expired. For taxpayers still paying the assessment normally, the future dates were September 8 for the 8th installment, October 7 for the 9th and November 9 for the 10th. If you are reading this after those dates, check the Portal do Contribuinte again, because the status of a payment slip changes after its due date.
Not every taxpayer receives ten installments. The annex to Decree No. 8,429 ties the number of installments to the total assessed amount. The table starts with one installment for amounts up to R$ 100 and increases by ranges, reaching ten installments when the IPTU is above R$ 3,000. Therefore, "installment payment in up to ten installments" does not mean that every property will have ten payment slips available.
What to do when the payment slip or installment is overdue
If the installment is already overdue, do not treat an old payment booklet as if the amount and date were still current. Return to the Portal do Contribuinte, check the property's debt and look for issuance of the document that corresponds to the current situation. The municipal Tax Code provides for late-payment charges, interest and monetary adjustment for taxes paid after the deadline, so the amount due may differ from what was originally printed.
If the portal does not present an updated payment slip, if there is a discrepancy in the registration data or if you cannot identify which debt is outstanding, use Semfaz assistance before paying. Its headquarters is at Praça General Valadão, 341, Centro, and the service hours reported by City Hall are Monday through Friday, from 8 a.m. to 4 p.m. The general phone number is (79) 3179-1100. The Portal do Contribuinte offers online self-service.
Is the 7.5% discount still valid?
No. For the 2026 IPTU, City Hall announced a 7.5% discount for a single payment. The original deadline was January 16 and it was extended through February 6, 2026. That window has already closed.
This detail matters because search results may display old pages, terms from previous tax years or third-party texts with different percentages, including 10%. To deal with the IPTU during the year, do not use an old discount as a reference for the current amount. Check the 2026 tax year in the portal and use the payment slip issued for the property's situation at that time.
How to recognize a payment slip before paying
The safest route is to generate the document from fazenda.aracaju.se.gov.br or enter the portal through the official City Hall website. Before completing payment, check the tax year, the
property registration, the selected installment or debt, the amount and the due date. If the payment slip offers PIX through a QR Code, as occurred in the 2026 campaign, scan it from the document generated through the official channel and review the details shown by your bank before confirming.
If any information does not match the property, or if the link was received through a message, advertisement or page that does not belong to the official domain, do not proceed merely because the screen looks similar to City Hall's. Return to the official address and repeat the inquiry.
The shortest route to resolve IPTU issues during the year
For a duplicate bill or installment inquiry, start with Semfaz's Portal do Contribuinte at fazenda.aracaju.se.gov.br. Check the 2026 tax year and the current status of the debt. If an installment is overdue, generate or request a document compatible with the updated amount. If the question cannot be resolved in the portal, use official Semfaz assistance.
The central point is not to mix the promotional campaign from the beginning of the year with the routine of paying throughout 2026. The 7.5% discount has passed, the calendar continues to advance and the official portal is the reference for knowing what is still open, what is overdue and which payment slip should be used.
