Tax Year and Filing in Colombia

The tax year (año gravable) in Colombia constitutes the 12-month period commencing January 1 and concluding December 31, serving as the temporal reference for accrual and computation of income tax liabilities across all tax categories.

Didactically: (1) It delineates the fiscal calendar for aggregating taxable events, mandating taxpayers to consolidate revenues, costs, and deductions within this Gregorian-aligned span; (2) alternatively, as the "gravable unit," it encapsulates all renta-generating facts for declaration purposes, irrespective of payment timing.

Colombian tax doctrine, as articulated by Alfredo Chaves Quijano in Derecho Tributario Sustantivo (U. Externado, 2018), conceptualizes the año gravable not merely as a chronological container but as the crystallization nexus for hecho generador realization, aligning Colombia's system with accrual-based principles akin to IFRS yet tempered by administrative pragmatism. Roberto Stegmann (Tratado de Impuesto sobre la Renta, 2020) emphasizes filing's dual role: self-assessment (autoliquidación) and transparency instrument, critiquing perennial calendario shifts as eroding predictability. Recent scholarship post-L. 2277/2022 underscores digitalization's transformative impact, reducing evasion yet amplifying access divides for SMEs.
