You moved to Medellín, or Bogotá, or Santa Marta. Your income is the same as it was. Your bank is now Bancolombia. And somewhere around month seven you found out that the United States never stopped taxing you, and that Colombia has started.
That is the whole problem in one sentence. Two countries, both claiming your worldwide income, and no treaty between them to sort out who gets what. This guide explains exactly what each side wants, what relief actually exists, and which of it applies to you.
Figures verified 9 September 2026. Colombian tax law changed materially between December 2025 and September 2026, so confirm anything time-sensitive before you act on it.
Do Americans in Colombia really have to file two tax returns?
Very often, yes.
The United States taxes its citizens and green card holders on worldwide income, regardless of where they live. There is no “I live abroad now” exemption. If your income clears the normal filing thresholds, you file a Form 1040 from Colombia exactly as you would from Ohio.
Colombia taxes residents on worldwide income too. If you are not a Colombian tax resident, Colombia only taxes your Colombian-source income.
So the question that decides whether you have one return or two is not your visa. It is your day count.
When does Colombia start taxing my worldwide income?
Article 10 of the Colombian tax code is presence-based and visa-irrelevant. You become a Colombian tax resident when you spend more than 183 days — meaning 184 — in Colombia during any rolling 365-day window. Not a calendar year. Any 365 consecutive days.
The details that catch people out:
- Entry and exit days both count. A weekend in Cartagena is two days, not zero.
- Non-consecutive days aggregate. Four separate six-week trips add up.
- Where the window straddles two years, residency lands in the second year.
- A digital nomad visa does not protect you. Nothing in the residency test depends on visa type. The V visa for nómadas digitales does not count toward permanent residency, but it does absolutely nothing to stop you becoming a tax resident on day 184.
Residency also attaches through family or centre of economic interests in Colombia, and through specific rules for Colombian nationals living abroad.
The full mechanics, including how to count a split year, are in our guide to the 183-day rule.
Once you are resident, Colombia wants a declaración de renta covering your worldwide income if you cross any of the AG2025 triggers (all figures use UVT 2025 of $49,799):
| Trigger for AG2025 | UVT | COP |
|---|---|---|
| Gross income | 1,400 | $69,718,600 |
| Gross assets (patrimonio bruto) | 4,500 | $224,095,500 |
| Credit card consumption | 1,400 | $69,718,600 |
| Total purchases | 1,400 | $69,718,600 |
| Bank deposits or investments | 1,400 | $69,718,600 |
Note the assets trigger. It is measured on your worldwide assets once you are resident, and a modest US retirement account will clear it on its own.
Is there a US–Colombia tax treaty?
No. There is no income tax treaty between the United States and Colombia, and there is no totalization (social security) agreement either.
That absence shapes everything below, and most people arrive believing the opposite, because two other agreements do exist:
- A Tax Information Exchange Agreement signed in 2014. It shares taxpayer data. It reduces exactly zero withholding rates.
- A FATCA intergovernmental agreement — Model 1, signed 20 May 2015, in force 27 August 2015. Colombian banks report US account holders to DIAN, which passes the data to the IRS.
So you get the information-sharing burdens of a treaty relationship and none of the reliefs. No tie-breaker article to stop both countries treating you as resident. No reduced Colombian withholding on dividends or interest paid to you. No pension article. No totalization certificate of coverage. We cover the consequences in detail in why there is no US–Colombia tax treaty.
What you have instead are the unilateral reliefs in US law. They are real, and for most people they are enough. They are just not automatic.
What relief do I actually get against double taxation?
Three mechanisms, and choosing between them is the central planning decision of your expat tax life.
The Foreign Earned Income Exclusion (Form 2555)
Excludes a capped amount of earned income — salary, wages, self-employment profit. Not dividends, not interest, not rental income, not pensions.
| Tax year | Maximum FEIE per qualifying person | Default housing limit |
|---|---|---|
| 2024 | $126,500 | $37,950 |
| 2025 | $130,000 | $39,000 |
| 2026 | $132,900 | $39,870 |
To qualify you need a tax home in Colombia plus either the bona fide residence test (an uninterrupted period including an entire tax year) or the physical presence test (330 full days in any 12 consecutive months).
The foreign housing exclusion
Layered on top of the FEIE. It excludes qualified housing expenses above a base amount — 16% of the maximum exclusion, which the IRS printed as $20,800 for 2025 — up to a cap.
Here is the part almost nobody publishes: Colombia is on the IRS high-cost housing list. For both 2025 and 2026, the limit is $58,700 a year for Bogotá and $49,400 a year for every other Colombian city, against a default of $39,000 (2025) and $39,870 (2026). If your housing costs are genuinely high, that is thousands of dollars of additional exclusion that the standard software prompts will never mention.
The Foreign Tax Credit (Form 1116)
A dollar-for-dollar credit for Colombian income tax paid, against the US tax on the same income. It has no cap, it covers investment and rental income as well as earned income, and unused credits carry back one year and forward ten.
Do not accept the shortcut you will read elsewhere — that Colombia’s top rate of 39% beats the US top rate of 37% so the credit always wins. That compares top marginal rates. Colombia’s 39% band only begins above 31,000 UVT of taxable income, and the cédula general allows substantial deductions and exempt income, so a mid-income American in Medellín can face a Colombian effective rate well below the US rate. Then the credit leaves residual US tax and the exclusion may be better. It is a calculation, not a rule of thumb, and it is worked through properly in FEIE vs foreign tax credit in Colombia.
One warning that belongs on this page: revoking the FEIE once elected locks you out of it for the next five tax years without IRS approval. This is not a decision to flip year to year on a whim.
What do I have to report even if I owe nothing?
Most of the catastrophic outcomes in expat tax are not about tax. They are about unfiled information returns, where the penalty applies whether or not a single dollar of tax was due.
| Form | Triggered by | Filed with |
|---|---|---|
| FinCEN 114 (FBAR) | Foreign financial accounts exceeding $10,000 in aggregate at any point in the year | FinCEN, separately from your return |
| Form 8938 | Specified foreign financial assets above $200,000 (single, abroad) or $400,000 (MFJ, abroad) at year end | IRS, attached to Form 1040 |
| Form 5471 | Owning 10% or more of a Colombian SAS or other foreign corporation | IRS, attached to Form 1040 |
| Form 8858 | Owning a foreign disregarded entity or operating a foreign branch | IRS, attached to Form 1040 |
| Form 3520 | Gifts or bequests over $100,000 from a non-resident alien or foreign estate | IRS, filed separately |
The FBAR threshold is an aggregate, any-point-in-time test, not a year-end test and not per account. A cuenta de ahorros, a cuenta corriente, a CDT and signature authority over your company’s account are summed together. Signature authority alone counts even if the money is not yours. The current civil penalties are $16,536 for a non-willful violation and the greater of $165,353 or 50% of the balance for a willful one, per the regulations effective 17 January 2025. See FBAR and FATCA for Americans in Colombia.
Form 5471 is the one that ambushes small business owners. Form a Colombian SAS, own all of it, and you are a filer — with a $10,000 base penalty per corporation per year, an additional $10,000 per 30 days after IRS notice up to $50,000, and a reduction to your foreign tax credits on top. That is the case even for a dormant company with no profit. Read Form 5471 and your Colombian SAS before you incorporate, not after.
What happens to my self-employment tax?
This is where the missing totalization agreement costs real money.
Self-employment tax applies to US citizens abroad on exactly the same terms as at home, once net earnings reach $400. The rate is 15.3% — 12.4% Social Security up to the wage base ($184,500 for 2026) plus 2.9% uncapped Medicare, with an additional 0.9% Medicare tax above $200,000 single, $250,000 married filing jointly, $125,000 married filing separately.
Three things make this brutal in Colombia specifically:
- The FEIE does not reduce self-employment tax. You can exclude every dollar of your income from income tax and still owe 15.3% on the whole net profit.
- The foreign tax credit does not reduce it either. SE tax is not an income tax, so §901 credits do not reach it.
- There is no totalization agreement to elect out of one system. A self-employed American resident in Colombia is contributing to Colombian health, pension and ARL on their ingreso base de cotización and paying 15.3% US self-employment tax on the same earnings, with no mechanism to relieve either.
The mitigations are structural rather than clerical — usually a question of entity choice, which reintroduces the Form 5471 machinery. There is no clean answer here, only a trade-off, and it deserves a real conversation before the year starts rather than in April.
What about my investment income and the NIIT?
The Net Investment Income Tax is 3.8% on the lesser of net investment income or modified AGI above $200,000 (single), $250,000 (married filing jointly) or $125,000 (married filing separately). It reaches interest, dividends, capital gains, rental and royalty income — including Colombian rental income.
Two traps stack here:
- Excluded income is added back. Amounts you exclude under §911 go back into MAGI for NIIT purposes, so the FEIE does not keep you under the threshold.
- The foreign tax credit cannot offset it. The credit operates against Chapter 1 tax; the NIIT sits in Chapter 2A. Taxpayers in France and Canada have won treaty-based arguments to credit foreign tax against the NIIT, but those cases turned on treaty text. Colombia has no treaty, so that route is closed. For Americans in Colombia the NIIT is an unrelievable 3.8% on top of whatever Colombia charges.
Separately: be extremely careful with Colombian fondos de inversión colectiva. Depending on how the fund is structured, a US person may be looking at punitive PFIC treatment on Form 8621, or foreign trust reporting on Forms 3520/3520-A, or both. The classification has to be analysed fund by fund. Do not buy one on a comisionista‘s recommendation without US advice first.
What are my deadlines?
United States, for Americans abroad:
| Date | What |
|---|---|
| 15 April | Interest starts running on unpaid tax, extensions notwithstanding. FBAR nominally due |
| 15 June | Automatic 2-month extension to file, no form required, if you live and work outside the US |
| 15 October | Extended deadline via Form 4868, filed before 15 June. Also the automatic FBAR extension date |
| 15 December | Discretionary further extension, requested by letter |
Form 2350 is a different animal: it buys time for someone who needs more days to qualify for the FEIE under the bona fide residence or physical presence test.
The rule people forget: an extension to file is not an extension to pay. Interest runs from 15 April regardless.
Colombia, for the AG2025 return being filed now: 12 August to 26 October 2026, sequenced by the last two digits of your NIT. Following the 10 August 2026 earthquake, Decreto 1171 moved those dates to 27 October – 13 November 2026 for taxpayers domiciled in Cali, Palmira, Tuluá, Buenaventura, Pereira, Armenia, Manizales, Quibdó and Popayán.
One more Colombian-side point worth checking: use UVT 2025 ($49,799) for the AG2025 return you are filing during 2026. UVT 2026 ($52,374) applies to next year’s return. Several Colombian outlets have published the AG2026 threshold as though it applied now.
What if I haven’t filed in years?
You are in a very large club, and the situation is usually more fixable than it feels at 3am.
The IRS runs the Streamlined Foreign Offshore Procedures for people whose failure to file was non-willful — negligence, inadvertence, mistake, or a good-faith misunderstanding of the law. For taxpayers who genuinely live abroad, the miscellaneous offshore penalty is zero. The submission is three years of returns, six years of FBARs, and a signed certification of non-willfulness.
The eligibility conditions are strict and the certification is made under penalty of perjury, so this is not a self-service form to fill in over a weekend. But it exists, it works, and it closes the file. See streamlined procedures for Americans in Colombia.
One thing you can fix this week
If you send money to Colombia, check how you are funding the transfer.
IRC §4475 imposes a 1% excise tax on remittance transfers funded with cash, a money order, a cashier’s check or a similar physical instrument, for transfers made after 31 December 2025. Transfers funded by withdrawal from an account at a regulated US financial institution, or by a US-issued debit or credit card, are not taxed.
Same money, same destination, same provider. Fund it from your US bank account or card and the 1% does not apply.
Two systems, one adviser
You have two tax systems, no treaty to arbitrate between them, and a set of unilateral US reliefs that work well if you elect them correctly and expensively if you do not. The residency question is decided by day count, not visa. The exclusion-versus-credit question is a calculation specific to your numbers. The reporting forms carry penalties that have nothing to do with how much tax you owe. And self-employment income is the one place where the missing agreements genuinely cost you money with no fix on the compliance side.
None of that is a reason to panic. It is a reason to get one adviser looking at both returns together, rather than a US preparer who has never seen a declaración de renta and a Colombian contador who has never seen a Form 1116.
Frequently asked questions
If I pay tax in Colombia, do I still have to file in the US? Yes. Filing is required whenever your income clears the normal thresholds, regardless of what you paid Colombia. The credit and the exclusion reduce what you owe; they do not remove the obligation to file, and both must be claimed on a filed return.
Does my digital nomad visa keep me from becoming a Colombian tax resident? No. Colombian tax residency turns on days present, not visa category. Past 183 days in any rolling 365-day window you are a resident, taxable on worldwide income, whatever your visa says.
Can I just use the FEIE and stop worrying? Only if all your income is earned, it fits under the cap, and you have no reporting obligations. The FEIE does not touch self-employment tax, does not cover investment or rental income, does not help with the NIIT, and does not excuse an FBAR.
Will the IRS actually find my Colombian bank account? Assume yes. The FATCA intergovernmental agreement has been in force since August 2015, and Colombian financial institutions report US account holders through DIAN.
Is residence-based taxation about to pass so I can stop filing? No. The bill introduced in the 118th Congress died in committee, and as of this writing nothing has been enacted. Do not plan around it.
