One of the most critical — and most misunderstood — issues for expats living in Colombia is tax residency. Many foreigners assume their home country status fully protects them from Colombian tax obligations. That assumption can be costly. Under Colombian law, once you are considered a tax resident, you owe income tax on your worldwide income — not just what you earn in Colombia.
How Does Colombia Determine Tax Residency?
Under Colombian Tax Code (Article 10, Estatuto Tributario), you are considered a Colombian tax resident if you meet ANY ONE of the following criteria in a given calendar year:
- You spend 183 days or more (continuous or aggregate) in Colombia during any 365-day period that overlaps a tax year
- Your primary economic interests are in Colombia (e.g., 50%+ of assets or income is Colombian-sourced)
- Your center of vital interests is in Colombia (family, permanent home, main business)
- You are a Colombian national with residency not accredited abroad
⚠️ The 183-Day Rule Is More Complex Than It Looks
The counting period is ANY 365-day window, not just the calendar year. A trip to Colombia from August to February (6+ months) can trigger residency even if you were in country for only 5 months in one calendar year.
What If You Are a Tax Resident?
As a Colombian tax resident, you must:
- Declare worldwide income to DIAN — including foreign salaries, rental income abroad, investment gains, etc.
- Disclose foreign assets on your annual tax return
- File an annual income tax return (Declaración de Renta) by the DIAN deadline
- Potentially pay wealth tax if your total net worth exceeds COP 72 billion (~USD 17.5M)
What If You Are NOT a Tax Resident?
Non-residents pay Colombian income tax only on Colombian-sourced income, at a flat rate of 35%, generally withheld at source. They are not required to declare worldwide income or foreign assets.
| Status | Tax on Colombian Income | Tax on Foreign Income |
|---|---|---|
| Resident | Progressive rates (0–39%) | Yes — worldwide income |
| Non-resident | 35% flat (withheld) | No |
Does the US–Colombia Tax Treaty Help?
As of 2026, Colombia does not have a comprehensive double tax treaty with the United States. American expats in Colombia face the risk of double taxation — paying both Colombian and US taxes on the same income. Proper structuring is essential. The US Foreign Earned Income Exclusion (FEIE) and Foreign Tax Credit can provide partial relief, but professional coordination between both countries' tax rules is critical.
Practical Strategies for Expats
- Track your days in Colombia precisely — use a travel log
- Structure your assets and income sources before the 183-day threshold
- Consider whether a Colombian visa type affects residency determination
- Work with a bilingual CPA who understands both Colombian and US/UK tax law
