If your household moves in 2025, there’s one tax detail you shouldn’t ignore. The Tax Authority allows you to update the household composition until February 28, 2026, an essential step for the Automatic IRS to work correctly or for the Model 3 declaration to appear pre-filled with correct data. Missing this deadline could result in errors in tax assessment or loss of tax benefits.
Updating the household is an annual procedure, but it only becomes mandatory when there are relevant changes in the taxpayer’s personal or family situation. Even so, even those who did not register changes must confirm that the information on the Finance Portal is correct.
Why is it important to confirm the household
The IRS is calculated based on several personal factors, from marital status to the number of dependents, including the existence of shared custody or tax residence.
According to information released by the Tax Authority and cited by the website Pplware, specialized in current affairs and technology, this data is crucial for calculating deductions, the family quotient and access to the Automatic IRS.
If the information is not up to date, the system may assume incorrect data and lead to a less favorable settlement, requiring the delivery of a replacement declaration.
In what situations should you update the data
The household update must be carried out whenever, throughout 2025, any of the following situations have occurred:
- Birth of a son
- Divorce or separation
- Dependents under joint custody
- Children who have reached the age of 26
- Death of a member of the household
According to the same source, these are the most common cases that require communication to the Tax Authority, to ensure that the declaration reflects the taxpayer’s family reality.
How to update the household on the Finance Portal
The process is carried out exclusively online and does not require in-person travel. To update the household, you must access the Finance Portal and enter the IRS reserved area.
After authenticating, you must select the option related to the household and confirm the data presented. If there are new dependents, you can add them through the “Add dependent” option, available at the bottom of the page.
After this step, the system forwards information regarding the household’s permanent housing. This is where data such as the tax address appears, which must match the information contained in the property register.
Final confirmation and submission
After checking all the fields, the procedure follows a simple sequence: confirm or fill in the data, proceed to the next step and submit. Only after submission does the Tax Authority consider the information validated for IRS purposes.
According to the explanation, many common errors arise precisely because the taxpayer leaves the page without completing the final submission, leaving the process incomplete.
What happens if you don’t update
If you do not update the household within the legal deadline, the Tax Authority will consider the data from the previous year. This may affect the amount of tax payable or received, especially in situations involving the birth of children, shared custody or a change in marital status.
Furthermore, a poorly defined aggregate may prevent access to the Automatic IRS, requiring manual delivery of the Model 3 declaration.
A simple step that can avoid problems
Updating your household is one of the simplest steps in the tax calendar, but also one of the most forgotten. Still, it has a direct impact on the IRS calculation and the speed with which the process takes place.
Confirming this information in advance is a practical way to avoid surprises when it comes time to submit the declaration, ensuring that the tax reflects your real and updated situation.
