Almost everything written in English about the Colombian 183-day rule contains the same mistake: it describes the count as a calendar-year test. It is not. It is a rolling 365-day window, and that single difference is what catches people who thought they had planned their year carefully.
This article is the long version — the mechanics of Article 10 of the Estatuto Tributario, a worked day-count, the triggers besides physical presence, and what Colombian tax residency actually costs you once it arrives.
One thing to establish before anything else, because it undoes a very widespread belief: nothing about Colombian tax residency depends on your visa type. Not the digital nomad visa, not an M visa, not an R visa, not a tourist stamp. DIAN’s residency criteria do not mention immigration status at all. A tourist who overstays can be a Colombian tax resident; an R-visa holder who spends the year abroad may not be.
What does Article 10 ET actually say about the 183-day rule?
The physical presence test reads, in the original: “Permanecer continua o discontinuamente en el país por más de ciento ochenta y tres (183) días calendario incluyendo días de entrada y salida del país, durante un periodo cualquiera de trescientos sesenta y cinco (365) días.”
Unpacked, that is five separate rules, each of which is routinely reported wrongly:
| The rule | What it means |
|---|---|
| “Más de 183 días” | The threshold is more than 183 days. Day 184 triggers it. Exactly 183 days does not. |
| “Incluyendo días de entrada y salida” | Both your arrival day and your departure day count as full days in Colombia. A weekend trip out costs you fewer days than you think. |
| “Continua o discontinuamente” | Days do not have to be consecutive. Leaving and re-entering does not reset the count. |
| “Un periodo cualquiera de 365 días” | Any 365-day period — a rolling window that can start on any date. It is not the calendar year. |
| Split-year rule | Where the 365-day window spans two tax years, residency takes effect in the second of those years. |
The rolling-window point is the one that does the damage. If the test were “days in the calendar year,” a person could spend five months in Colombia from August to December, leave, come back in January for another five months, and never be resident. Under the actual rule, those two stays sit inside a single 365-day window and add together.
A worked example: how the count really runs
Take a straightforward case.
Sofía is a designer with foreign clients. She has no Colombian income at all. She arrives in Medellín on 1 August 2025 and stays until 15 December 2025, then goes home for the holidays and comes back on 10 January 2026, staying until 20 March 2026.
First stay: 1 August – 15 December 2025
| Month | Days counted |
|---|---|
| August (1–31, arrival day counts) | 31 |
| September | 30 |
| October | 31 |
| November | 30 |
| December (1–15, departure day counts) | 15 |
| Subtotal | 137 |
She leaves at 137 days. She is not resident — she is comfortably under the line — and she goes home believing the clock has reset.
Second stay: 10 January – 20 March 2026
| Month | Days counted |
|---|---|
| January (10–31, arrival day counts) | 22 |
| February 2026 | 28 |
| March (1–20, departure day counts) | 20 |
| Subtotal | 70 |
| Running total | 207 |
Now find the crossing point. She needs 47 more days after 137 to reach 184. Counting from 10 January as day one, day 47 falls on 25 February 2026.
On 25 February 2026 she is inside a 365-day window that opened on 1 August 2025, and she has been present in Colombia for 184 days within it. She is a Colombian tax resident.
Note what she did not do. She did not spend more than 183 days in either calendar year — 137 days in 2025, 70 days in 2026. Every calendar-year calculation would have told her she was safe. The rolling window says otherwise.
Which year does it land in? The 365-day window straddles 2025 and 2026, so residency takes effect in the second year: 2026. She is a Colombian tax resident for the 2026 tax year — the AG2026 return, filed in 2027 — on worldwide income, including income earned before 25 February and income earned after she flew out in March. Colombian residency attaches to the tax year as a whole; there is no split-year mechanism that switches you on halfway through.
If instead she had arrived on 1 January 2026 and crossed 184 days on 3 July 2026, the window would sit entirely inside one year and residency would apply to 2026 directly. Same outcome, different route.
The practical takeaway: count backwards, not forwards. At any moment, the question is how many days you have spent in Colombia during the preceding 365 — not since January.
If you want the arithmetic done on your own dates, keep the stamps. Passport entry and exit stamps, boarding passes and Migración records are the evidence base, and reconstructing three years of travel from memory is far worse than keeping a spreadsheet from the start.
What are the other ways to become a Colombian tax resident?
Physical presence is the main route but not the only one. Article 10 also captures:
Colombian diplomatic service abroad. Persons connected to Colombian diplomatic missions who are exempt from tax in the host state under the Vienna Conventions.
Colombian nationals with family or economic ties to Colombia. A Colombian national living abroad is a tax resident if, during the year, any of the following applies:
- their spouse or permanent partner is a Colombian tax resident;
- their dependent minor children are Colombian tax residents;
- 50% or more of their income is Colombian-source;
- 50% or more of their assets are administered in Colombia;
- 50% or more of their assets are located in Colombia;
- they fail to prove tax residency in another country when DIAN requests it;
- they are resident in a low-tax or non-cooperative jurisdiction.
There is an escape valve on that criterion: it does not apply to a Colombian national who can prove that 50% or more of their annual income is sourced in, or 50% or more of their assets are located in, their country of domicile. That exception neutralises the nationality-plus-ties criterion only. It cannot override the 184-day physical presence test. A Colombian-American who spends most of the year in Bogotá cannot argue their way out with a US income statement.
Two observations for foreign readers. First, the family and economic-interest criteria are aimed at Colombian nationals abroad — they are not a general “centre of vital interests” test applied to foreigners with a Colombian partner. Second, the tax-haven criterion is a real trigger for Colombians who have relocated to low-tax jurisdictions and assumed the move was clean.
What does Colombian tax residency actually mean?
Here is the difference in one table.
| Tax resident | Non-resident | |
|---|---|---|
| Income taxed | Worldwide — Colombian and foreign source | Colombian-source only |
| Assets declared | Worldwide | Colombian-located only |
| Return | Formulario 210 | Formulario 110 |
| Rates | Progressive cedular system, 0%–39% (Art. 241 ET) | Flat 35% (Art. 247 ET, with exceptions) |
“Worldwide income” is the phrase to sit with. It means your foreign salary, your foreign freelance income, your dividends from a foreign brokerage, your rental income from a property in another country — all of it enters the Colombian return, converted to pesos. Which form you file, and on what basis, is covered in more depth in our piece on Formulario 210 vs Formulario 110. The conversion itself is less obvious than it sounds; see which TRM to use on a Colombian return.
The rate table
Colombian personal rates apply to bands measured in UVT of taxable income, not pesos, which is why every peso figure in this niche moves each January.
| From (UVT) | To (UVT) | Rate |
|---|---|---|
| 0 | 1,090 | 0% |
| 1,090 | 1,700 | 19% |
| 1,700 | 4,100 | 28% |
| 4,100 | 8,670 | 33% |
| 8,670 | 18,970 | 35% |
| 18,970 | 31,000 | 37% |
| 31,000 | + | 39% |
The UVT for 2025 is $49,799 and for 2026 $52,374 (DIAN Res. 000238 of 15 December 2025). The full set of current values lives on our 2026 rates and thresholds page.
The filing thresholds
Being a tax resident and being obliged to file are two different questions. For AG2025 — the return filed between August and October 2026 — the thresholds use UVT 2025 ($49,799):
| Trigger | UVT | COP (AG2025) |
|---|---|---|
| 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 |
Anyone who is a responsable de IVA files regardless of amount.
A precision point that is currently being reported wrongly in Colombian consumer media. Filing thresholds are measured in the UVT of the taxable year, not the year you file. Several mainstream outlets have published $73,323,600 as the current income threshold. That figure is 1,400 × UVT 2026 and belongs to the AG2026 return, filed in 2027. The AG2025 return being filed now uses 1,400 × $49,799 = $69,718,600. If a page quotes the wrong one, check what else it got wrong. There is more on who has to file in do I have to file a Colombian tax return.
The AG2025 calendar for personas naturales runs 12 August – 26 October 2026, staggered by the last two digits of the NIT (Decreto 2229 de 2023). One live exception: following the earthquake of 10 August 2026, Decreto 1171 moved the deadlines to 27 October – 13 November 2026 for taxpayers domiciled in Cali, Palmira, Tuluá, Buenaventura, Pereira, Armenia, Manizales, Quibdó and Popayán.
The declaration nobody expects: activos en el exterior
Separately from the income tax return, Colombian tax residents whose foreign assets exceed 2,000 UVT must file a declaración de activos en el exterior (Formulario 160). Assets above 3,580 UVT must be itemised individually.
Two thousand UVT is a low bar, and the peso figure depends entirely on which year you are declaring. For AG2025, 2,000 × $49,799 (UVT 2025) = $99,598,000. For AG2026, 2,000 × $52,374 (UVT 2026) = $104,748,000. Either way, somewhere in the region of a few tens of thousands of US dollars. A modest foreign brokerage account, a retirement account, or equity in a property abroad can put a new resident over it without any Colombian income at all. Always use the UVT of the year being declared, not the year you file — and see our dedicated article on the declaración de activos en el exterior.
Do I need a cédula and a RUT?
These are separate systems from residency, and they follow their own rules.
Cédula de extranjería. Foreigners holding M and R visas, and V visas valid for more than 3 months, must register in the Registro de Extranjeros with Migración Colombia and obtain a cédula. The deadline is 15 calendar days, counted from the date the visa was approved (if applied for from inside Colombia) or from the date of entry (if applied for from abroad). Missing it can trigger administrative proceedings and fines. Holders of visitor visas for tourism, business, crew and events, and diplomatic or official courtesy visitor visas, are exempt regardless of validity — but the V–Nómada Digital is not on that exemption list, so digital nomad visa holders do need one. There is a fee, payable by card at the appointment. Migración Colombia re-indexes it each year, so take the current amount from Migración’s own site — a peso figure quoted in an article, including this one, would be stale within months.
RUT. You need a Registro Único Tributario when you become a Colombian tax resident, when you provide services to Colombian companies, when payments to you are subject to retención en la fuente, when you own a Colombian company or Colombian real estate, when you import or export, or when you need to issue electronic invoices. With a cédula de extranjería you can register virtually through DIAN’s Muisca platform. With only a passport, registration is generally in person at a DIAN office by appointment, with proof of a Colombian address. DIAN also runs a route for natural persons located abroad, which matters for non-resident property owners and foreign shareholders.
That is the practical reason the cédula matters to an accountant: without it, almost every tax and banking process becomes a slower, in-person exception.
The mistakes worth naming
“Leaving the country resets the clock.” It does not. Days aggregate across a rolling 365-day window, and both the departure and the return day count.
“I was under 183 days each calendar year, so I’m fine.” The test is not calendar-based. See Sofía above.
“Exactly 183 days makes me resident.” No — the threshold is more than 183. Day 184 is the trigger.
“My visa protects me.” It does not, in either direction. Visa type is irrelevant to Article 10. This is important enough that it has its own article: does the digital nomad visa make you a tax resident.
“I only have foreign income, so Colombia isn’t interested.” Residency brings worldwide income into the Colombian return. The source of the money is not the question; your presence is.
“Nobody tracks this.” Migración Colombia records every entry and exit, and Colombia participates in international information exchange. Assume the day count is knowable.
The rule in one paragraph
The Colombian 183-day rule is simpler than it looks and stricter than most people assume: more than 183 days — 184 — in any rolling 365-day period, counting your arrival and departure days, with non-consecutive stays adding together, and residency landing in the second year when the window straddles two. Visa type never enters into it.
If you are anywhere near the line, the useful work is arithmetic done in advance, not after. Count backwards over the last 365 days, keep the stamps, and decide deliberately whether you are planning to stay under the threshold or planning to file as a resident. Both are legitimate. Drifting into residency without noticing is the outcome that costs money.
A note on scope. Immigration rules and tax rules are separate systems, administered by different authorities under different bodies of law. We advise on the tax side: whether you are resident, what that means for your Colombian filings, and how it interacts with your obligations at home. For visa applications and immigration status, work with a Colombian immigration lawyer.

Frequently asked questions
Do entry and exit days count toward the 183 days in Colombia? Yes. Article 10 says so explicitly — “incluyendo días de entrada y salida del país.” Both ends of every trip count as full days.
Does leaving Colombia reset the 183-day count? No. The statute says continua o discontinuamente, so non-consecutive days aggregate. A trip out pauses the accumulation; it does not erase it.
What happens if my 183 days cross two calendar years? Where the 365-day window spans two tax years, residency takes effect in the second of those years. In the worked example above, the crossing happens on 25 February 2026 and residency applies to the 2026 tax year.
Is exactly 183 days safe? On the physical presence test, yes — the threshold is more than 183 days. But the margin is one day, and one delayed flight removes it. Anyone planning to land on 183 should build in a buffer and keep documentary proof of every movement.
I’m on a digital nomad visa. Does that change anything? Not for tax residency. Article 10 is presence-based and makes no reference to visa type. What the visa does change is the practical likelihood of crossing the threshold, since it runs for two years. That is covered in does the digital nomad visa make you a tax resident in Colombia.
Am I still resident if I leave halfway through the year? Residency is determined for the tax year, and it can be triggered by a window that closes after you have gone. Someone who becomes resident for a year and then departs still has a return to file for that year, on worldwide income. Departing does not undo the year that already qualified.
General information, not tax or legal advice. Figures verified 9 September 2026; Colombian tax law changed materially between December 2025 and September 2026, and every peso threshold moves each January with the UVT and the SMMLV. Confirm current figures before acting. Immigration rules are administered separately from tax rules — we advise on the tax side.
