The United States taxes its citizens on worldwide income — regardless of where they live. Colombia, once you meet residency criteria, also taxes your worldwide income. The overlap of these two systems creates one of the most complex tax situations any expat can face. The critical challenge: Colombia and the US do not have a comprehensive tax treaty to eliminate double taxation.
📌 US Citizens: You Must File Every Year Regardless
Unlike most countries, the United States requires all citizens and Green Card holders to file a US federal tax return every year, regardless of where they live or whether they owe any tax. Living in Colombia does NOT exempt you from this obligation.
The Double Taxation Problem
If you are a Colombian tax resident AND a US citizen:
- Colombia will tax your worldwide income at rates up to 39%
- The US will tax your worldwide income at rates up to 37%
- Without proper planning, both can tax the same dollar of income
US Tools to Avoid Double Taxation
1. Foreign Earned Income Exclusion (FEIE)
The FEIE allows US citizens abroad to exclude a significant portion of their foreign-earned income from US taxes. In 2025, the exclusion amount is approximately USD 126,500 per person. To qualify, you must pass either the:
- Bona Fide Residence Test: You're a bona fide resident of Colombia for a full calendar year
- Physical Presence Test: You spend 330+ days outside the US in any 12-month period
Important limitation: The FEIE applies only to earned income (salaries, self-employment income). It does NOT cover rental income, investment gains, dividends, or passive income.
2. Foreign Tax Credit (FTC)
The Foreign Tax Credit allows you to reduce your US tax liability dollar-for-dollar by taxes actually paid to Colombia. This is often more powerful than the FEIE for higher earners or those with significant investment income. You can use the FTC for Colombian income taxes paid on US-source income that is still US-taxable.
3. Foreign Housing Exclusion/Deduction
If you're abroad and qualify for the FEIE, you can also exclude or deduct housing costs above a base amount. This reduces your taxable income further and partially addresses the higher cost of maintaining two residences.
The Critical Gap: Passive Income Is Still Taxed by Both
The FEIE only covers earned (active) income. If you have:
- Rental income from Colombian properties
- Investment portfolio income
- Colombia-sourced dividends
- Capital gains from asset sales
…both the US and Colombia may tax this income. The Foreign Tax Credit helps mitigate this, but it requires careful management and often results in some residual double tax burden.
FBAR and FATCA Reporting
In addition to income taxes, US citizens with Colombian bank accounts must comply with:
- FBAR (FinCEN 114): Required if total foreign financial accounts exceed USD 10,000 at any point in the year
- FATCA (Form 8938): Required if total foreign assets exceed USD 200,000 (or USD 50,000 for single filers)
Failure to file these forms carries severe penalties — often more expensive than the underlying taxes themselves.
Practical Strategy for US Expats in Colombia
- File both Colombian and US returns annually
- Use the FEIE for earned income; use the FTC for passive and investment income
- Maintain excellent records of all taxes paid in Colombia as evidence for FTC claims
- Monitor your 183-day count carefully to manage Colombian residency timing
- Work with a CPA firm that understands BOTH US and Colombian tax law simultaneously
