Colombia Credit & Debit Notes: E-Invoicing Correction Rules Explained

Colombia's electronic credit notes (Notas Crédito) and debit notes (Notas Débito) must follow the same UBL 2.1 validation process as regular e-invoices, submitted to DIAN with a CUDE code and linked to the original invoice's CUFE. Issuing manual or paper-based correction notes is no longer valid — all adjustments must be electronic and DIAN-validated.

When Do You Need a Nota Crédito?

Returns: Customer returns goods, full or partial refund Discounts: Retroactive discounts applied after invoice issuance

A Nota Crédito (credit note) reduces the value of a previously issued electronic invoice:

• Returns: Customer returns goods, full or partial refund
• Discounts: Retroactive discounts applied after invoice issuance
• Price adjustments: Overcharging errors corrected
• Complete cancellation: Voiding the entire invoice (credit note for full amount)

When Do You Need a Nota Débito?

Undercharging corrections: Original invoice was below the correct amount Interest charges: Late payment interest added

A Nota Débito (debit note) increases the value of a previously issued invoice:

• Undercharging corrections: Original invoice was below the correct amount
• Interest charges: Late payment interest added
• Additional services: Post-invoice additions to the same transaction

What Are the Technical Requirements?

the Technical Requirements includes: Format: UBL 2.

• Format: UBL 2.1 XML with Colombian extensions (same as regular e-invoice)
• CUDE: Unique document code generated from the note's data
• Reference: Must include the original invoice's CUFE (unique invoice code)
• Discrepancy reason: Coded reason from DIAN's catalog (discount, return, correction, etc.)
• Digital signature: XAdES-BES from the issuer's certificate
• DIAN validation: Must be submitted and accepted by DIAN before being valid

Common Correction Scenarios

Scenario 1: Partial Return

1. Original invoice: COP 10,000,000 for 100 units
2. Customer returns 20 units
3. Issue Nota Crédito for COP 2,000,000 referencing original CUFE
4. Submit to DIAN for validation

Scenario 2: IVA Correction

1. Original invoice applied 5% IVA instead of correct 19%
2. Issue Nota Débito for the IVA difference
3. Reference the original invoice's CUFE

Scenario 3: Complete Cancellation

1. Issue Nota Crédito for the full invoice amount
2. Reference the original CUFE
3. Both documents remain in DIAN's system (invoices cannot be "deleted")
