US expat taxes in Colombia hinge on a single tripwire that catches even seasoned remote workers off guard: spend 183 days or more in the country within any 365 day period and DIAN, the Direccion de Impuestos y Aduanas Nacionales, stops treating you as a visitor and starts taxing your worldwide income as a Colombian resident, with no US-Colombia income tax treaty to soften the landing. Medellin and Bogota have turned into magnets for remote workers on the country's dedicated digital nomad visa, but the IRS keeps taxing US citizens and green card holders on worldwide income the entire time regardless of where they actually live, so once that 183-day line is crossed, two governments are taxing the same income with no treaty tie-breaker standing between them. An American living in Colombia has to build double-tax protection entirely out of the Foreign Tax Credit, the Foreign Earned Income Exclusion, and careful attention to a growing list of separate reporting requirements, since there is no totalization agreement covering social security either.
Do US Citizens Living in Colombia Have to File Both DIAN and US Tax Returns?
Yes, for anyone who qualifies as a Colombian tax resident. Colombia determines residency mainly on a time basis, generally reached by staying in the country 183 or more days within any 365 day period, and a resident is then taxed by DIAN on worldwide income, not just income earned inside Colombia. The United States applies a completely separate rule, taxing its citizens and green card holders on worldwide income no matter where they live, so US filing status never turns on how much time you actually spend in Colombia.
Because those two triggers run independently and there is no treaty tying them together, an American who has become a Colombian tax resident typically owes a DIAN return covering worldwide income and a US Form 1040 covering the same worldwide income for the same year. Paying Colombian tax does not excuse the US filing obligation, and filing in the US does not excuse the DIAN obligation. The Foreign Tax Credit and Foreign Earned Income Exclusion are what keep that overlap from becoming actual double taxation on the US side.
How Does Colombia Tax Residents on Worldwide Income?
Colombia taxes individual residents on worldwide income using a progressive rate structure that climbs as income rises, applied through DIAN's annual filing process. Because Colombia has become a major hub for remote workers, with Medellin and Bogota in particular drawing large digital nomad communities and a dedicated digital nomad visa category, a growing number of Americans cross the residency threshold without necessarily intending to become long-term Colombian tax residents.
Confirm the current year's bracket structure and deduction rules directly with a Colombian tax advisor or DIAN, since a stale figure can throw off both the local calculation and the US Foreign Tax Credit that depends on it. What matters for US planning purposes is simpler: once you cross the residency threshold, Colombian tax exposure on worldwide income becomes real, and it needs to be factored into your US return the same year it is incurred, not after the fact.
Should You Claim the FEIE or the Foreign Tax Credit on Colombian Income?
This is a closer call in Colombia than in many higher-tax expat destinations, because Colombia's progressive rates do not reliably exceed the comparable US rate at every income level. That makes a genuine year-by-year comparison worthwhile rather than defaulting to whichever election feels simpler.
The Foreign Tax Credit on Form 1116 credits Colombian income tax paid, computed by income category under IRC Sections 901 and 904, dollar for dollar against US tax, and any unused credit carries back one year and forward ten years on Schedule B. The Foreign Earned Income Exclusion on Form 2555 instead excludes foreign earned income up to an annually indexed maximum, for example $130,000 for 2025, under IRC Section 911. The FEIE does nothing to reduce self-employment tax, a real issue for the many Americans in Colombia working as independent contractors, can disqualify a family from the refundable Additional Child Tax Credit, and once revoked generally cannot be re-elected for five years without IRS consent. See our FEIE versus Foreign Tax Credit comparison for the full decision framework.
What Does the US-Colombia Tax Treaty Do for Double Taxation?
Nothing, because no comprehensive US-Colombia income tax treaty has ever been signed and ratified. That puts Colombia in the same position as several other major Latin American expat destinations, and it means the tie-breaker residency rules, saving clause carve-outs, and treaty-based pension deferral provisions that shape planning in treaty countries are simply not available to Americans in Colombia.
Double-tax relief instead rests entirely on domestic US law: the Foreign Tax Credit under IRC Sections 901 and 904, and the Foreign Earned Income Exclusion under IRC Section 911. Colombian income tax paid is generally still creditable on Form 1116 as a matter of the Internal Revenue Code itself, so the absence of a treaty does not eliminate relief, but it does mean there is no treaty article to fall back on if a dual-residency conflict or an unusual income type falls outside what the Code and its regulations already address.
Does the US Have a Totalization Agreement with Colombia?
No, and this is one of the more expensive gaps for self-employed Americans in Colombia. The United States and Colombia have never signed a totalization agreement, so there is no certificate of coverage process available to exempt a worker from paying into one country's social security system while covered by the other. That is a meaningful difference from countries that do have an agreement in place with the United States.
For a US employee sent to Colombia by a US employer, this mainly affects Colombian pension system contributions required locally. The bigger exposure falls on self-employed Americans working from Colombia, including the many digital nomads and independent contractors based in Medellin and Bogota, who can owe full US self-employment tax on their net earnings with no Colombian totalization credit to offset it, on top of whatever Colombian pension contributions apply under local law. Our guide to totalization agreements and self-employment tax abroad explains how the certificate of coverage process works in countries that do have an agreement, which is useful context for understanding exactly what Colombia is missing.
How Are Colombian Pensions and Retirement Accounts Taxed by the US?
Not automatically deferred, and this is where the missing treaty bites again: without a treaty provision to fall back on, Colombia's mandatory pension system and any private supplementary retirement vehicle don't get tax-deferred treatment in the US simply because Colombian law treats them favorably.
The general US default rule, under IRC Sections 401(a) and 402(b), taxes income accruing inside a foreign retirement arrangement to a US person currently, unless a specific tax treaty provision defers it. Because no US-Colombia treaty exists, that exception is not available, so every Colombian pension or retirement account has to be evaluated under the general default rule rather than any treaty carve-out. Our foreign pension US tax treatment guide walks through the four questions that determine the outcome for any foreign plan: whether growth is taxed as it accrues, whether a treaty defers it, what has to be reported, and how distributions are eventually taxed.
Are Colombian Investment Funds Taxed as PFICs?
Usually, yes, and it catches out plenty of newly settled nomads who open a local brokerage account in Bogota or Medellin instead of leaving their portfolio with a US firm. A Colombian mutual fund or other pooled investment vehicle typically meets the definition of a passive foreign investment company under IRC Section 1297, with Sections 1291 and 1298 governing the tax treatment. That classification is purely a matter of US tax law, does not depend on how the fund is regulated or taxed inside Colombia, and applies with equal force whether or not a tax treaty exists.
Once a fund crosses into PFIC territory, the IRS default is harsh: absent a timely election, gains and certain distributions get spread across your entire holding period, taxed at the top rate in effect for each of those years, and layered with an additional interest charge. Each PFIC generally requires its own Form 8621 filing, often even in a year with no distribution and no tax actually due, which is why Americans relocating to Colombia are usually better off keeping their investment accounts at a US-based brokerage rather than opening one locally.
What Else Do You Have to Report to the IRS?
Filing a return to DIAN and one to the IRS is not the end of it: Colombian financial accounts and investment funds carry their own separate reporting duties that apply whether or not any US tax is actually owed, and none of them hinge on a tax treaty that doesn't exist. These filings are enforced separately from the income tax return, and the penalties for missing them typically dwarf whatever tax would have been due on the underlying account.
The Colombia Reporting Stack
Reference- FBAR (FinCEN Form 114). Required when the combined balance of your Colombian bank, brokerage, and pension-related accounts exceeds $10,000 at any point during the year. See our FBAR filing guide.
- Form 8938 (FATCA, IRC §6038D). A separate filing threshold, higher for Americans living abroad, that can require you to list the same Colombian accounts directly on your federal tax return. See our Form 8938 guide.
- Form 8621 (PFIC). Generally required for each Colombian mutual fund or other pooled investment fund that qualifies as a passive foreign investment company. See our PFIC and Form 8621 guide.
For a nomad who spent months testing out Medellin or Bogota on a tourist stamp before applying for the digital nomad visa and settling into full residency, whether the IRS even counts you as a US resident for part of that year is a separate question, governed by the substantial presence test.
Bottom Line
The 183-day mark is the whole story for US expat taxes in Colombia: cross it and there is no tax treaty standing by to soften what happens next. With no income tax treaty and no totalization agreement in place, the Foreign Tax Credit and the Foreign Earned Income Exclusion have to carry the entire double-tax planning burden on their own, and self-employed Americans in particular need to plan around the full US self-employment tax exposure that a totalization agreement would otherwise offset. Get the residency call wrong, or skip the reporting stack that comes with it, and the penalties will dwarf whatever Colombian or US tax was actually at stake.
