The income tax declaration calendar in Colombia will have an exceptional change this year for taxpayers in the areas affected by the magnitude 7.4 earthquake that shook the country on August 10. The earthquake, with its epicenter in San José del Palmar, Chocó, caused damage in various municipalities in the west and center of the country and led the Government to adopt extraordinary measures to ease the obligations of those facing the emergency.

Among these measures is the modification of deadlines to file and pay the income tax declaration corresponding to the 2025 taxable year. The change does not eliminate the tax obligation for individuals who meet the requirements to declare; what changes is the deadline.
The measure aims to give additional leeway to households and taxpayers affected by the earthquake. According to the authority, the postponement represents a cash flow relief estimated at 624 billion pesos: 213 billion corresponding to income tax and 411 billion related to withholdings.
Who must declare income tax?
The obligation to declare income tax does not depend solely on income. According to DIAN, individuals who are tax residents in Colombia must file the declaration corresponding to the 2025 taxable year if they meet at least one of the conditions provided by tax legislation. Among the criteria are exceeding certain thresholds of assets, income, purchases, consumption, or financial transactions.
You must file the income tax declaration if you meet any of the following conditions as of December 31, 2025:
- Gross assets: That they have been higher than 4,500 Tax Value Units (UVT), that is, 224,096,000 pesos
- Gross income: That in 2025 they have been equal to or greater than 1,400 UVT, equivalent to 69,719,000 pesos
- Credit card consumption: That during 2025 they have exceeded 1,400 UVT or 69,719,000 pesos

Who are the beneficiaries of the postponement?
The postponement is aimed at individuals and undivided estates whose tax domicile is within the areas covered by the emergency measure. The reference to determine the taxpayer’s location is the domicile registered in the Single Tax Registry (RUT) as of August 10, 2026, the date the earthquake occurred.
The included jurisdictions correspond to the following DIAN branches:
The measure also includes an exception for those who register for the first time in the RUT and have their domicile in one of the affected areas. In these cases, the benefit may apply even if the registration is made after August 10.
The recommendation for taxpayers who have changed domicile or who do not have updated information in the RUT is to keep documents that can prove their residence, such as neighborhood certificates, lease contracts, or utility bills.
