Where these dates come from

Since 2024 the tax calendar is permanent (Decree 2229 of 2023): each deadline is a set business day of the month, by NIT or ID number. Saturdays, Sundays, public holidays and days that are non-working for national public entities (such as the civic day on the third Friday of April, Decree 500 of 2024) don’t count.

The 2026 dates match DIAN’s published calendar one by one.

Other obligations, such as exogenous information, the simple tax regime’s yearly return and advance payments, wealth tax, transfer pricing or municipal taxes, are not included. The foreign assets return is due on the same dates as income tax, and the national consumption tax on those of bimonthly VAT.
