The Decree 1226 of August 18, 2026 establishes special deadlines for certain tax obligations of individuals and illiquid estates affected by the seismic event that occurred on August 10, 2026.
The measure adds transitional paragraphs to articles 1.6.1.13.2.15. and 1.6.1.13.2.33. of Decree 1625 of 2016 and contemplates special rules for the income and complementary tax return for tax year 2025, the return of assets held abroad, and withholding and self-withholding at source returns.
Who do the special deadlines apply to?
For the income tax return for tax year 2025, the measure applies to individuals and illiquid estates required to file who, as of August 10, 2026, had their tax domicile in municipalities belonging to the following sectional directorates:
- Cali, Palmira, Tuluá and Buenaventura, in the department of Valle del Cauca.
- Pereira, in Risaralda.
- Armenia, in Quindío.
- Manizales, in Caldas.
- Quibdó, in Chocó.
- Popayán, in Cauca.
The tax domicile for the purposes of these deadlines is the one reported in the RUT as of August 10, 2026.
Changes made afterward to the RUT do not trigger the application of these special deadlines, unless the taxpayer demonstrates, through legally admissible evidence, that their domicile was located in one of the benefiting municipalities before the seismic event occurred.
New deadlines for 2025 income tax
The due dates are determined according to the last two digits of the NIT as stated in the RUT, disregarding the verification digit:
| Last two digits of the NIT | Due date |
|---|---|
| 01 and 02 | Eighteenth business day of October |
| 03 and 04 | Nineteenth business day of October |
| 05 and 06 | Twentieth business day of October |
| 07 and 08 | Twenty-first business day of October |
| 09 and 10 | First business day of November |
| 11 and 12 | Second business day of November |
| 13 and 14 | Third business day of November |
| 15 and 16 | Fourth business day of November |
| 17 and 18 | Fifth business day of November |
| 19 and 20 | Sixth business day of November |
| 21 and 22 | Seventh business day of November |
| 23 and 24 | Eighth business day of November |
| 25 and 26 | Ninth business day of November |
The same deadlines apply to individuals and illiquid estates in the indicated municipalities that were already required to file the income tax return for tax year 2025 before the Decree entered into force.
In these cases, the Decree establishes that no late-payment interest or penalties will apply.
The special deadlines also apply to the return of assets held abroad.
The measure also covers income tax taxpayers who register in the RUT for the first time, provided they have their domicile in the indicated municipalities and the last two digits of their NIT fall within one of the established ranges.
Withholding and self-withholding at source
The Decree establishes a special deadline for withholding agents and self-withholders who, as of August 10, 2026, have their tax domicile in one of the municipalities covered by the measure.
These taxpayers may file and pay the monthly withholding and self-withholding at source return corresponding to July 2026 within the deadlines established for the return corresponding to August 2026.
The same rule applies to those who were required to file the return corresponding to July before the Decree entered into force.
When the return and payment are made within the special deadline, no late-payment interest or penalties will apply.
The other deadlines for filing and paying withholding and self-withholding at source returns remain unchanged.
Large Taxpayers
The Decree expressly establishes that none of its provisions apply to Large Taxpayers.
Entry into force
Decree 1226 of August 18, 2026 takes effect the day after its publication in the Official Gazette and transitionally adds articles 1.6.1.13.2.15. and 1.6.1.13.2.33. of Decree 1625 of 2016.
Individuals, illiquid estates, withholding agents and self-withholders who consider themselves to be within the scope of the measure must verify their tax domicile as of August 10, 2026, the corresponding tax obligation, and the last two digits of the NIT to determine the applicable deadline.
