Colombia operates one of Latin America’s most comprehensive real-time clearance e-invoicing systems, managed by the national tax authority DIAN. Nearly all commercial transactions must be digitized, with invoices validated by DIAN before delivery to the buyer.

1. Scope and Applicability

• Domestic B2B & B2G: All VAT-registered businesses must issue Factura Electrónica de Venta (FEV). Invoices require real-time DIAN clearance before delivery. The same rules apply to sales to government entities (mandatory since November 2020).
• Domestic B2C: Businesses issue either a standard FEV or an approved Documento Equivalente Electrónico (DEE) (e.g., validated POS receipts). Paper receipts have been largely replaced; by November 2024, most consumer-facing transactions required electronic reporting.
• Cross-Border:
  • Exports: Special electronic export invoice (0% VAT), cleared in real time by DIAN.
  • Imports/Purchases from non-invoicing parties: Colombian buyer issues a Documento Soporte (self-billing/support document) and submits it to DIAN for validation to claim deductions/credits.
• Triangulation/Chain Transactions: Each leg requires a separate e-invoice or equivalent, cleared by DIAN. No special exemptions.
• Special Regimes: Handled within the standard system using appropriate tax codes (e.g., “exento” or “excluido” with 0% VAT).

2. Taxable Persons

Applies to all individuals and legal entities required to issue invoices under Colombian law, including all VAT-registered businesses (large and small).

Foreign entities without Colombian tax registration do not issue e-invoices directly; buyers use Documento Soporte.

Exemptions exist for certain financial services, specific public transport, and persons below VAT thresholds. Voluntary adoption is allowed but requires full technical compliance. DIAN provides free tools for micro/small enterprises.

3. Implementation Timeline

• 1995: Legal equivalence for electronic invoices.
• 2013–2016: Pilots and optional regime.
• 2018–2019: Mandatory for large taxpayers under clearance model.
• November 2020: Mandatory for all VAT-registered taxpayers across B2B, B2G, and B2C.
• 2021: Law 2155 expanded coverage to electronic payroll and support documents.
• 2022–2024: Focus on retail with Documento Equivalente Electrónico. Resolution 000165 (Nov 2023) set staggered 2024 deadlines for various document types (utilities, transport, event tickets, etc.). By November 2024, the regime became near-universal.
• 2025–2026: Ongoing refinements, including simplified buyer data at POS, sector-specific grace periods (e.g., 48 hours for utilities), and integration with supply chain finance (RADIAN).

4. Technical & Functional Requirements

• Format: XML based on UBL 2.1 with DIAN extensions; must be digitally signed with an accredited 509 certificate. A human-readable PDF with QR code is generated, but the validated XML is the legal record.
• Key Data: Supplier/buyer NIT, sequential invoice number (DIAN-authorized range), line items, taxes, total in COP, CUFE (96-character SHA-384 hash), digital signature.
• Model: Real-time Continuous Transaction Control (CTC) clearance. No separate periodic e-reporting file — validation itself constitutes reporting.
• Process: Invoice transmitted to DIAN for automated validation (schema, arithmetic, signature). Approval (with timestamp and CUFE) is usually received in seconds. Rejected invoices are invalid and must be corrected/re-submitted.
• Channels: DIAN free web service (low volume), direct API, or authorized Technology Service Providers (PST).
• Contingency: Offline issuance allowed; must be transmitted within 48 hours of system restoration.

5. Error Correction

Direct modification of validated invoices is prohibited. Corrections use:

• Electronic Credit Note (to reduce/annul) or Debit Note (to increase).
• Both notes and any replacement invoice must reference the original CUFE and be cleared by DIAN. A validated credit note legally nullifies the original (fully or partially).

6. Self-Billing – Documento Soporte

Buyers issue this electronic XML document (with signature and DIAN clearance) for purchases from suppliers not obligated to invoice (e.g., unregistered persons, foreign suppliers). It must be generated at or near the time of purchase.

7. Archiving & Retention

Documents must be retained for 5 years (from January 1 of the following year) in their original validated XML format with signature and DIAN stamp. Offshore storage is permitted if readily accessible to DIAN.

8. Penalties & Enforcement

• Formal errors: Up to 1% of invoice value (capped at 950 UVT ≈ USD 9,000).
• Failure to issue/report: 5% of the transaction value (same cap).
• Repeated non-compliance: Temporary business closure (or heavy fine in lieu).
• Buyers cannot claim VAT credits or deductions on non-compliant invoices.
• DIAN uses automated cross-checks and encourages consumers to demand e-invoices (“¡Exige tu factura!”).

9. Pre-Filled VAT Returns

DIAN generates suggested VAT returns (“declaración sugerida de IVA”) based on issued/received e-invoices. Taxpayers remain fully responsible for accuracy and must make adjustments if needed.

10. Impact on SMEs

Phased rollout, free DIAN tools, and guidance eased adoption. Initial costs (certificates, software) have decreased due to competition and free options. Benefits include up to 80% lower invoicing costs, faster payments, access to financing via RADIAN, reduced errors, and accelerated digital transformation/formalization.
