**TL;DR:** Sales-rep travel allowances in Colombia need per-trip documentation to survive a DIAN audit. Reclassification as salary triggers four years of back contributions.

- Tax Statute Art. 130: occasional vs permanent
- Logbook + receipts + report in 30 days
- Pay under a separate concept
- Reclassification = 4-year parafiscal back-pay

## Why DIAN is watching travel allowances in 2026

DIAN's 2026 Audit Plan flagged sales-rep travel allowances as one of six priority targets. During 2024-2025, many companies shifted parts of compensation into 'viáticos' to dodge social-security contributions and withholding. DIAN responded with mass cross-referencing between PILA (payment ledger) and travel-allowance reports.

## Occasional vs permanent

Article 130 of the Tax Statute distinguishes:

- **Occasional**: paid for a specific trip. Not labor income, not in the employee's income certificate, deductible to the company.
- **Permanent**: paid regularly as part of the role's package. Labor income, subject to withholding and social-security/parafiscal contributions.

Monthly payments at similar amounts are presumed permanent unless the company proves otherwise.

## Minimum documentation per trip

Signed policy, prior authorization, trip log (date, route, specific business purpose), receipts (e-invoice for fuel, tolls, lodging, meals), expense report approved within 30 days, and bank payment confirmation. Missing any of these is a common cause of disallowed deductions.

## Mileage rate

DIAN sets no rate. 2026 market: COP 1,200-1,800/km depending on vehicle and region. Document the methodology, apply equally to comparable roles, and revisit quarterly against published fuel prices.

## Withholding exposure

When DIAN reclassifies viáticos as permanent salary, the cost compounds: withholding for the last 4 years, social-security and parafiscal contributions, 100% surcharges, and statutory interest. A 12-rep, 3-year case typically costs COP 800M-1.2B.

## Common mistakes

Flat monthly payments with no link to real travel; year-end reconstructed logs; missing fuel/lodging receipts; cash payments without bank trace; policies not updated in 3 years; reimbursement >50% of base salary with no detailed documentary justification.

## Frequently asked questions

### Can travel allowance be paid in cash?

Yes, but you lose traceability. Above 100 UVT, DIAN requires a bank instrument.

### How long to retain the documentation?

Five-year minimum (DIAN statute of limitations); ten years recommended for higher-risk cases.
