Becoming a Colombian Tax Resident (183 days, worldwide income)

The short version

Colombia does not wait for a calendar year to ask the tax-residence question. The core day-count rule looks at whether an individual remains in Colombia for more than 183 calendar days, continuous or discontinuous, including arrival and departure days, during any 365 consecutive days.

That matters because Colombian fiscal residence is not just a local paycheck issue. A Colombian tax resident can move into a worldwide-income and worldwide-asset analysis under Colombian tax law, while a U.S. citizen still has the U.S. return, foreign tax credit, FBAR, Form 8938, and investment-classification file to manage.

What the law actually says

DIAN’s Article 10 residence guidance sets out the residence rule for individuals. It treats an individual as a Colombian tax resident if the person remains in Colombia for more than 183 calendar days, continuously or discontinuously, including days of entry and exit, during any 365 consecutive day period. If the presence period spans more than one taxable year, the statute says residence is considered to begin in the second taxable year or period.

Article 9 is the paired tax-base rule. It says individuals, whether Colombian or foreign, who are residents in Colombia are subject to income tax and complementary taxes on income and occasional gains from both Colombian and foreign sources, and on patrimony possessed inside and outside Colombia. Nonresidents are generally subject only on Colombian-source income and Colombian-situated patrimony.

Those two articles are the spine of the issue. Article 10 answers when the person becomes a Colombian fiscal resident. Article 9 explains why the answer matters. For an American, this is layered on top of U.S. citizenship-based tax filing. The IRS U.S. Citizens and Resident Aliens Abroad page says U.S. citizens and resident aliens abroad generally report worldwide income the same way they would if living in the United States.

The tax problem is not simply “Where did I sleep most nights?” It is whether the travel calendar causes Colombia to ask for worldwide income and patrimony while the United States still asks for worldwide income, foreign-asset reporting, and the right relief mechanism on the U.S. return.

How it works in practice

Assume a U.S. citizen arrives in Colombia in September and keeps returning through the following year. She does not spend a clean January-to-December year there. She spends blocks of time in Medellín, visits the United States, returns to Bogotá, and spends another block in Colombia.

That pattern can still matter because Article 10 uses any 365 consecutive day period. The question is not only whether she spent more than 183 days in Colombia during a single calendar year. The question is whether any rolling 365-day window crosses the more-than-183-day line, counting both entry and exit days.

If the window crosses two taxable years, the timing detail matters. Article 10 states that when the continuous or discontinuous stay in Colombia falls over more than one year or taxable period, the individual is considered resident beginning in the second year or taxable period. That makes the move calendar part of the tax file. The file should preserve entry and exit records, flight data, lease dates, visa or permit records, work-location records, and income timing.

Once Colombian tax residence is triggered, the next question is not just whether income was earned in Colombia. Article 9 moves the resident analysis to income and occasional gains from Colombian and foreign sources, and to patrimony inside and outside the country. For a U.S. taxpayer, that means a U.S. brokerage account, private-company interest, crypto position, U.S. real estate, retirement account, or non-Colombian bank account may become relevant to the Colombian analysis even if the asset never moved to Colombia.

The U.S. return then has to be built around the same facts. The U.S. citizen still reports worldwide income. Foreign tax credit may help with double-tax pressure, but it is a calculation and not a promise. The IRS Foreign Tax Credit page, Form 1116 page, and Publication 514 all point toward a facts-and-limits review, not a simple receipt-based answer.

The numbers

These are the thresholds and rules to put into the move calendar before the taxpayer crosses the Colombian residence line.

The file to build before the line is crossed

1. A day-count file

The first workpaper is a day-count calendar. It should not be a memory exercise. Keep passport stamps, airline itineraries, boarding passes, lease dates, hotel stays, visa or permit records, and any Colombian entry and exit confirmations you can lawfully obtain.

For Article 10, the file needs to answer four questions:

Which 365-day windows did you test?
How many Colombia days were inside each window?
Did you count entry and exit days?
If the window crossed two taxable years, which year is the second year or period?

That last question is easy to miss. A person can think, “I did not spend a full tax year in Colombia,” and still have a rolling-window problem. Colombia’s rule is not written as a full-calendar-year rule.

2. An income-source file

Once residence is possible, income needs to be sorted by type and source. U.S. consulting income, Colombian employment income, investment income, capital gains, crypto sales, pension income, and rental income do not all behave the same way.

The Colombian side asks whether the person is resident, then looks to Article 9. The U.S. side still asks for worldwide income from a U.S. citizen. The U.S. foreign tax credit review then needs the foreign tax paid or accrued, income categories, timing, exchange rate, limitation basket, and support for Form 1116.

This is where people get into trouble with simple answers. Paying Colombian tax does not automatically eliminate U.S. tax. Claiming the foreign earned income exclusion does not automatically cover investment gains or self-employment tax. A Colombian move has to be documented as a two-country file.

3. An asset and patrimony file

Article 9 uses patrimony language, and Colombia’s wealth-tax provisions use UVT-denominated thresholds. For a U.S. taxpayer who becomes a Colombian tax resident, that means the asset inventory matters before the return is prepared.

The inventory should identify bank accounts, brokerage accounts, retirement accounts, crypto wallets, private-company interests, real estate, foreign entities, and liabilities. It should distinguish gross assets from net wealth because the Colombian wealth-tax threshold is a net-wealth concept.

The DIAN statute describes a 72,000 UVT individual threshold for the wealth-tax review in Articles 292-3 and 294-3, and DIAN announced that Resolution 000238 of 2025 sets the 2026 UVT at COP 52,374. Article 295-3 describes a 12,000 UVT exclusion for the home where the individual actually lives most of the time. Article 296-3 gives the marginal individual wealth-tax rate table, including 0.5%, 1.0%, and, for 2023 through 2026, the temporary 1.5% bracket. Separate 2026 emergency rules apply to certain legal entities and permanent establishments, so the owner of a company or entity should not treat the individual threshold as the whole analysis.

4. A U.S. reporting file

The U.S. reporting file has to run separately from the Colombian income-tax answer. A Colombian bank or brokerage account may trigger FBAR if a U.S. person has a financial interest in or signature authority over aggregate foreign financial accounts over $10,000 at any time during the calendar year, subject to exceptions. The IRS and FinCEN both publish FBAR guidance.

Form 8938 can apply to specified foreign financial assets under a separate threshold regime. For a taxpayer living abroad who files other than jointly, the IRS Do I Need To File Form 8938 threshold page gives $200,000 at year-end or $300,000 at any time, but only after applying the specified-person, specified-asset, return-filing, and living-abroad rules.

Local investing can add another layer. A Colombian pooled investment vehicle treated as a foreign corporation for U.S. tax purposes may require passive foreign investment company, or PFIC, review if it meets Section 1297’s passive income or passive asset test. Form 8621 can then become part of the U.S. file if the taxpayer is a direct or indirect PFIC shareholder in a reporting situation listed by the IRS.

What this means for you

If you are planning to spend serious time in Colombia, do the tax-residence work before the travel calendar becomes messy. The practical file is simple to name and annoying to rebuild later:

A rolling 365-day Colombia calendar.
The exact first day of Colombian tax residence, if Article 10 is triggered.
A U.S. and Colombian income-source schedule.
A patrimony and net-wealth schedule.
A U.S. foreign-account and foreign-asset reporting schedule.
A list of local investments that require PFIC or entity-classification review.

Colombia may still be the right move. The issue is not whether the country is attractive. The issue is whether the taxpayer can prove when Colombian fiscal residence began and what income and assets were in the file at that point.
