No U.S.–Colombia Tax Treaty

Bilateral status as of May 2026

As of May 18, 2026, there is no comprehensive income tax treaty between the United States and the Republic of Colombia. None is in force, none has been signed, and no public negotiating round is on the Treasury or Hacienda calendar. The U.S.–Colombia bilateral tax architecture consists of two narrow instruments and nothing else:

• The Agreement Between the Government of the United States of America and the Government of the Republic of Colombia for the Exchange of Information Relating to Taxes — the TIEA — signed at Bogotá on March 30, 2001 and entered into force on April 30, 2014 (U.S. Department of State, Treaties and Other International Acts Series 14-430).
• The FATCA Model 1 Intergovernmental Agreement, signed on May 20, 2015, which obliges Colombian financial institutions to report U.S. account-holders to DIAN, which then forwards the data to the IRS, and vice versa.

Neither instrument is an income tax treaty. Neither caps withholding, allocates taxing rights, breaks dual-residence ties, or opens a competent-authority forum. Together they amount to a one-way mirror: each tax authority can see into the other's accounts, but the substantive rules that prevent double taxation between the two countries do not exist.

The negotiating record is short. Exploratory rounds were held in 2008, 2014, and 2016; none produced initialed text. After the U.S. Tax Cuts and Jobs Act of 2017, the entire U.S. treaty pipeline froze while Treasury worked through the implications of GILTI, BEAT, and the participation exemption for treaty partners. Colombia's worldwide-income system, its 2022 dividend-tax overhaul, and its 10% top-rate surtax further complicated the U.S. position. The file has been dormant ever since.

The tie-breaker gap

The starkest consequence of the treaty vacuum is the absence of a residency tie-breaker. Article 4(2) of the OECD Model — and every income tax treaty Colombia has signed — provides a sequential test (permanent home, center of vital interests, habitual abode, nationality, competent-authority resolution) that forces dual residents into a single residency for treaty purposes. No such mechanism exists between the United States and Colombia.

A U.S. citizen who exceeds 183 days of physical presence in Colombia during any rolling 365-day window becomes a Colombian tax resident under Article 10 of the Estatuto Tributario (ET). Colombia then taxes that individual on worldwide income. The United States, on a separate track, continues to tax the same individual on worldwide income on the basis of citizenship. Both sovereigns claim the entire base — no Article 4(2) sequence intervenes to assign primary taxing rights.

The only mitigation available is unilateral: each country grants a foreign tax credit (FTC) for taxes paid to the other, subject to its own sourcing and limitation rules. As we will see, the absence of treaty re-sourcing means the FTC fails to neutralize U.S.-source income — the most common income category for American retirees and remote workers.

Colombia-side withholding without a treaty

For Colombian-source payments to a non-resident U.S. person, there is no treaty schedule to fall back on. Statutory rates apply in full. The most important rates for fiscal year 2026:

One legislative footnote worth noting: the 2025 tax reform proposal would have raised the non-resident dividend withholding rate to 30%. That measure was rejected by the Senate Finance Commission on December 9, 2025, so the 20% rate remains in force for 2026. Americans cannot count on it staying that way — without a treaty, every statutory revision is a unilateral risk the U.S. citizen bears alone.

U.S.-side withholding without a treaty

The U.S. side of the asymmetry has two faces.

For the U.S. citizen who lives in Colombia: citizenship-based taxation means the individual files a full Form 1040 on net basis. The 30% gross-basis withholding on FDAP income (dividends, interest, rents, royalties) that applies to non-resident aliens does not apply to U.S. citizens. So a Colombian-resident American does not directly suffer the 30% NRA rate on her own U.S. portfolio income.

For Colombian-citizen family members and Colombian entities: the picture is brutal. A Colombian-citizen spouse receiving U.S.-source dividends, a Colombian SAS receiving U.S. royalties, or a Colombian-resident parent receiving U.S. pension income all face the full 30% statutory withholding rate under IRC §§871(a) and 881. Treaty residents in Mexico, Chile, or the United Kingdom would see that rate fall to 5%–15% under their respective treaties. Colombian recipients have no such relief. For mixed-nationality households, that 30% rate is a quiet but enormous tax on cross-border family wealth transfers.

No treaty re-sourcing — the most expensive consequence

This is the single most damaging gap, and the one most often missed in pre-move planning.

U.S. citizens living abroad use the Foreign Tax Credit (Form 1116) to avoid double taxation. The FTC is computed by income basket. Crucially, the credit allowed against U.S. tax on a given basket is limited to the foreign-source portion of taxable income in that basket. U.S.-source income, by default, generates no foreign-source numerator, so foreign tax paid on that income cannot offset U.S. tax — it strands.

Congress addressed this in IRC §§865(h), 904(d)(6), and 904(h)(10), which permit a U.S. citizen resident in a treaty country to re-source specified U.S.-source items — typically dividends, interest, capital gains, and pension income — to the country of residence by treaty. The re-sourced amounts are reported on a separate Form 1116 in the "Certain income re-sourced by treaty" basket, and the foreign tax paid on that income can finally be credited.

The arithmetic is unforgiving. A U.S. citizen in Medellín drawing $80,000 per year of U.S. dividends pays U.S. tax on that income (qualified dividend rates plus NIIT). Colombia also taxes the same dividends as worldwide income at progressive rates that top out at 39% (35% plus the 4% surtax for individuals above the threshold). The Colombian tax on U.S.-source dividends cannot be re-sourced to Colombia for U.S. FTC purposes. The American pays both bills in full and watches a six-figure Colombian credit accumulate uselessly on her Form 1116 carryover schedule.

No Mutual Agreement Procedure

Every modern income tax treaty includes a Mutual Agreement Procedure (typically Article 25 of the OECD Model). MAP gives a taxpayer caught in a conflict — a transfer-pricing adjustment, a residency dispute, a disagreement over the character of an income item — a competent-authority forum to negotiate a single, coordinated outcome between the two tax administrations.

U.S. citizens in Colombia have no MAP. The TIEA does not provide one; the FATCA IGA does not provide one. A Colombian-resident American hit with an IRS transfer-pricing adjustment on her consulting income and a parallel DIAN assessment on the same fees has no bilateral forum to resolve the conflict. Her recourse is limited to:

• Unilateral FTC claims, with all the limitation and sourcing problems described above;
• Colombian administrative litigation under Law 1437 of 2011 (the CPACA), starting with a recurso de reconsideración before DIAN and proceeding, if needed, to the contencioso-administrativo courts;
• Parallel U.S. administrative appeals and, ultimately, U.S. Tax Court.

Two separate, uncoordinated processes — one in each country — on the same facts. There is no mechanism to force them to agree.

No reduced rates on pensions, royalties, gains, or students

Treaties typically carve out preferential rules for pensions and annuities, Social Security, royalties, capital gains, and students/teachers/researchers. None of these is available between the U.S. and Colombia. In practice:

• U.S. Social Security received by a Colombian-resident American: Colombia taxes it as worldwide pension income (subject to the 1,000 UVT/month exemption under ET Art. 206(5) for certain qualifying pensions); the U.S. taxes it under §86. No treaty bracket exists to allocate primary taxing rights to one country.
• U.S. pension distributions (401(k), IRA, defined-benefit plans): full U.S. tax, full Colombian tax, no treaty reduction.
• Royalties (literary, software, patent): 20% Colombian source withholding, no reduction; full U.S. taxation on net basis as a U.S. citizen.
• Capital gains on U.S.-listed securities held by a Colombian-resident American: U.S. long-term capital gains rates plus Colombia's 15% ganancia ocasional if held more than two years (otherwise ordinary income).
• Students, trainees, researchers: no exemption window; ordinary residency rules apply once the 183-day threshold is crossed.

Colombia's treaty network — what U.S. persons miss

The contrast with Colombia's other partners is what makes the U.S. gap feel especially punitive. Colombia maintains income tax treaties with (among others):

• Spain (2008), Chile (2009), Switzerland (2011), Canada (2012), Mexico (2013), South Korea (2014), India (2014), Portugal (2015), Czech Republic (2015), United Kingdom (2019), France (2022), Italy (2023), Japan (2024);
• Plus the multilateral Andean Community Decision 578 covering Bolivia, Ecuador, Peru, and Colombia.

The United States has more than 60 income tax treaties in force worldwide. The intersection of these two networks — countries with treaties to both the U.S. and Colombia — is large and includes most of the major European economies, Canada, Mexico, Chile, and Japan. A U.S. citizen relocating to Chile, Mexico, the United Kingdom, or Spain gets a fully reciprocal framework: tie-breaker, withholding caps, MAP, and treaty re-sourcing. The same citizen moving to Bogotá or Medellín gets nothing.

What the TIEA and FATCA IGA actually do

It is worth being precise about the two instruments that do exist, because in client conversations they are routinely mischaracterized as treaties.

The TIEA (TIAS 14-430)

The Tax Information Exchange Agreement authorizes the IRS and DIAN to exchange tax information on request. It covers federal income taxes on the U.S. side and the Colombian income tax and its complementary taxes on the Colombian side. The TIEA provides:

• Exchange of information on request (Article 5);
• Possibility of tax examinations abroad (Article 6);
• Procedures for confidentiality and use of information (Article 8).

It does not provide withholding-rate reductions, tie-breakers, permanent-establishment rules, MAP, arbitration, non-discrimination protection, or re-sourcing. It is a pure transparency instrument.

The FATCA Model 1 IGA

The IGA signed May 20, 2015 implements the Foreign Account Tax Compliance Act in Colombia. Colombian financial institutions report U.S. account-holders to DIAN, which transmits the data to the IRS. Reciprocally, U.S. institutions report Colombian account-holders to the IRS for transmission to DIAN. Like the TIEA, the IGA is information-only — it creates no substantive tax rules.

Practical scenarios

Scenario 1 — The retiree in Medellín

A 67-year-old U.S. citizen draws $80,000/year from a U.S. defined-benefit pension and lives full-time in Medellín. Colombia treats her as a tax resident under ET Art. 10 and taxes the pension as worldwide income, applying the 1,000 UVT/month exemption under Art. 206(5) to the portion that qualifies. The U.S. taxes the same pension on its own schedule. Because the pension is U.S.-source under §861, the Colombian tax cannot be re-sourced — it accumulates as a stranded FTC carryover that, in most cases, expires unused after the ten-year window of IRC §904(c).

Scenario 2 — The SAS owner

A U.S.-citizen entrepreneur owns 100% of a Colombian SAS that earned COP 2 billion of taxable profit. The SAS pays the 35% Colombian corporate tax. The after-tax profit is distributed as a dividend; because the profit was taxed at the corporate level, the dividend suffers a 20% non-resident withholding (the rate that would have been reduced to 5%–15% under almost any treaty). The U.S. owner then reports the dividend at qualified-dividend rates on her 1040 — but qualified-dividend treatment requires that the payer be a "qualified foreign corporation," and the §1(h)(11) definition is met only if the payer is a U.S.-treaty resident (it is not) or if the stock is readily tradable on a U.S. securities market. Most Colombian SAS dividends therefore land at ordinary income rates with FTC for the 20% withholding only.

Scenario 3 — Selling U.S. stock from Bogotá

The same retiree sells $200,000 of Apple stock held five years. The U.S. taxes the gain as long-term capital gain (sourced to the U.S. under §865(a)(1) as the residence of the seller — but for U.S. tax purposes she is a U.S. person, so this is U.S.-source). Colombia taxes the gain as ganancia ocasional at 15%. Without treaty re-sourcing the Colombian 15% cannot be credited against U.S. capital gains tax. Double taxation in full.

The pre-residency planning window

The year before crossing the 183-day threshold is the single most valuable planning window any U.S. citizen contemplating Colombia will ever have. Once Colombian residency triggers under ET Art. 10, the worldwide-income regime applies and no treaty exists to soften the blow. Common pre-residency moves include:

• Realizing built-in capital gains on U.S. brokerage positions while still a U.S.-only resident, so the gain falls outside Colombia's worldwide net;
• Completing Roth conversions from traditional IRAs and 401(k)s while only the U.S. taxes the conversion;
• Finalizing intergenerational gifts of appreciated U.S. assets, since Colombia has its own gift and inheritance regime that will reach worldwide assets once residency triggers;
• Restructuring concentrated stock positions via §1014 step-up planning, charitable remainder trusts, or qualified opportunity zone deferrals before the Colombian net catches them;
• Documenting the precise day-count against the rolling 365-day window — this is the only objective fact that determines when Colombian residency begins.
