These are located in the “Unclassified” field and can be reclassified or manually added, as long as the corresponding supporting documentation is available.
Tax payment in installments The SAT indicated that –this year– taxpayers who are determined to have a tax to pay can cover it in up to six installments, provided they file the declaration and make the first payment in April 2026.
Requirements for the annual declaration Password or an active e.firma. When the result of the declaration is a favorable balance equal to or greater than 10,000 pesos –even if it's just one peso–, you must send it with an e.firma. If the result is a tax to pay, you can pay it in up to six installments, but only if you file and pay the first one in April.

SAT's benefit On the SAT Portal, there will be an informative calendar that will allow taxpayers to identify the days with the highest system traffic during the 30 days the declaration can be filed, in order to facilitate the planning of this procedure.
“The tax authority works to strengthen the available tools to support taxpayers, with the aim of facilitating the voluntary compliance with this important tax obligation for the benefit of the country's development,” the SAT concluded.
SAT's Exemption Individuals who are taxed under the Resico regime may be exempt from filing the Annual Declaration. “Those who apply what is established in rules 3.13.20 and 3.13.21 may choose to file it”.
Improvements to the annual declaration application Additionally, the SAT has implemented the following improvements and updates to the form, with the aim of supporting those who will file this procedure:
You must complete each section of the declaration before moving on to the next. The detail of other exempt income is shown, breaking down the perceptions identified in the payroll CFDI that workers obtained during the fiscal year. The suggested pre-loading of information from withholding agents for declarants is shown, specifically for Business Activity, Rental, Resico, and technological platforms, which can also be consulted in the new Withholding Viewer. Individuals with income from interest paid by Sofipos will see two fields to capture the amount of taxable and exempt interest. New functionalities are integrated to apply the incentives provided for in the Plan Mexico, aimed at taxpayers who have an Authorization Certificate. Informative messages are presented to inform the taxpayer of their situation in case of modifying the pre-loaded data. In the “Personal Deductions” section, CFDIs that have any inconsistencies will be shown.
April is not just any month. It is the moment when the SAT puts you against the wall: you enter, declare your taxes or you get into trouble.
