Statute of limitations on DIAN tax collection:
legal extinguishment of tax debts and bank unfreezing with the reference tax-law firm in Colombia.

Under Colombian tax collection procedure, DIAN's legal action to collect tax obligations expires by statute of limitations within five (5) years pursuant to Article 817 of the Tax Statute (Estatuto Tributario - E.T., as amended by Article 53 of Law 1739 of 2014). This statutory period is counted from four distinct procedural milestones: 1) the filing deadline fixed by the national government for timely tax returns; 2) the actual date of submission for late-filed tax returns; 3) the date of submission of amending returns (respecting additional assessed taxes); and 4) the date of administrative finality (ejecutoria) of the official tax assessment or dispute decision. The statute of limitations may be decreed ex officio or upon debtor petition by authorized DIAN officials. It is critical to distinguish the collection statute of limitations (5 years, Article 817 E.T.) from the finality of private tax returns (firmeza, 3 years general rule under Article 714 E.T.) and from statutory forfeiture of penalty powers (caducidad), which operate at entirely separate procedural stages.

Under Article 818 of the Tax Statute (as amended by Article 81 of Law 6 of 1992), the collection limitation period is strictly INTERRUPTED by four statutory events: formal service of the payment order (mandamiento de pago, Article 826 E.T.), granting of formal payment facilities (Article 814 E.T.), court admission of a debt restructuring petition (concordato), and official declaration of mandatory liquidation. Once interrupted, the 5-year clock restarts on the day following service of the payment order, termination of the concordato, or closing of mandatory liquidation; if a payment agreement is declared breached, collection resumes. Furthermore, the term is SUSPENDED from the order suspending auction proceedings until finality of the resolution deciding revocation, the resolution correcting address notification errors under Article 567 E.T., or a definitive court ruling under Article 835 E.T. Critical warning: under Article 819 of the Tax Statute, any payments made to satisfy a time-barred debt can neither be offset nor refunded, even if paid without knowledge of the statute of limitations. Upon service of a payment order (Article 826 E.T., with a citation to appear for notification within 10 days), the debtor has fifteen (15) days after notification to pay or file exceptions (Article 830 E.T.), among which Article 831(6) E.T. expressly establishes the exception of statute of limitations, to be decided within the following month (Article 832 E.T.). Under Article 829-1 E.T., substantive merits that should have been debated during prior assessment appeals cannot be raised during collection. Under Article 101 CPACA, only decisions resolving exceptions in favor of the debtor, ordering execution to continue, or liquidating the credit are actionable before administrative courts. Additionally, the law provides for the remission of certain debts under specific conditions (Article 820 of the Tax Statute).
