Colombia has never signed a comprehensive income tax treaty with the United States. For dividends from US stocks, that means the full 30% default withholding applies, with no reduced rate to claim via W-8BEN.
On the Colombian side, how a capital gain on US stocks is taxed depends heavily on one number: how long you held the position. Colombia draws a sharp line at two years, and which side of that line you’re on changes the applicable rate dramatically.
Colombia Has No Treaty - So 30% It Is
Absent a treaty, filing W-8BEN will not move the rate. It records you as non-US and keeps off backup withholding - 24%, lower but applied to gross proceeds too - while the statement still reads 30%.
Capital gains: the US generally does not tax capital gains realized by a non-resident alien on US securities under domestic law (IRC §871), independent of treaty status - this part doesn’t depend on a US-Colombia treaty existing at all.
First: Are You Actually a Colombian Tax Resident?
Everything below turns on this, and it is settled by a day count - not by where your broker sits, where your money lands, or what passport you hold.
Article 10 of the Estatuto Tributario makes you a Colombian tax resident if you spend more than 183 calendar days in the country, continuous or discontinuous, within any 365 consecutive calendar days. Three details in that sentence do real work:
- “More than 183” means 184. At 183 days exactly you are not resident; one more day flips it.
- The days need not be consecutive, and entry and exit days both count. Four separate trips add up the same as one long stay.
- The window is any rolling 365 days, not the calendar year. It can straddle a year boundary - and when the qualifying stay spans more than one taxable period, residency takes effect from the second year, not the first.
If you are not a Colombian tax resident, Colombia taxes only Colombian-source income, and a dividend from a US company is not that. The entire Colombian half of this guide simply does not apply to you. That is why this is the first question, not the last.
Colombia’s Side: The 2-Year Line Between Two Very Different Rates
Colombian tax residents are taxed on worldwide income, including dividends and capital gains from US stocks. For capital gains specifically, Colombia applies one of two entirely different regimes depending on the holding period:
Held 2 years or more: the gain is classified as ganancia ocasional (“occasional gain”) and taxed at a flat 15% - a preferential rate well below Colombia’s top marginal income tax bracket.
Held less than 2 years: the gain is taxed as ordinary income at Colombia’s progressive rates, which run from 0% up to 39% for tax residents - potentially more than double the long-term rate for an investor in a higher bracket.
The practical gap: an investor in the top bracket realizing a short-term gain can pay up to 39% on it, while the identical gain realized just past the two-year mark is taxed at 15%. That’s a larger rate differential than the holding-period distinctions covered for most other countries in this series, making the exact acquisition date of each lot worth tracking with real discipline rather than approximation.
Foreign dividends from sources like US stocks are taxed at Colombia’s ordinary progressive rates (0%-39%) - the same schedule that applies to short-term gains, with no preferential treatment analogous to the ganancia ocasional rate available for long-held capital gains.
The Two-Year Line, Priced
Colombia’s holding-period rule is the single biggest lever a Colombian investor has, and it is entirely within their control. On a $25,000 gain:
| Held | Colombian classification | Tax | Kept |
|---|---|---|---|
| 2 years or more | ganancia ocasional, flat 15% | $3,750 | $21,250 |
| Under 2 years, top bracket | ordinary income, up to 39% | $9,750 | $15,250 |
Selling a month early can cost $6,000 on this position - not through any change in the investment, only in the calendar. That is a far larger swing than the missing treaty produces on the dividend side, which is why the article opened by saying the holding period matters more than the treaty here.
Dividends have no such escape. A $3,000 US dividend loses $900 to the 30% statutory withholding at source, with Colombian treatment applying to what remains - and with no treaty, no instrument guarantees the US tax credits against it.
The TRM Trap: Which Exchange Rate Values Your US Holdings
A Colombian return is filed in pesos, so every dollar figure on your brokerage statement has to be converted using the tasa representativa del mercado (TRM). The intuitive assumption - take the TRM on 31 December and convert everything - is the wrong one for assets, and it is a common enough error to be worth stating plainly.
Since a 2022 change to the reporting instructions, foreign assets are carried at the TRM in force when the asset was first recognised - the rate on the day you bought it - rather than the year-end rate. Exchange-rate movement is picked up when you dispose of the position, not re-measured every December.
The practical effect is worth understanding. A position bought when the dollar was around COP 4,000 and still held after the rate moves to COP 4,300 does not, by itself, manufacture a Colombian gain out of the peso’s movement while you continue to hold it. Guidance published before 2022 says the opposite and is still circulating, so if your contador year-end-converts your whole portfolio, ask which rule they are applying.
Two Forms, and a Threshold Denominated in UVT
Colombian investors with a US brokerage account are usually dealing with two separate filings:
- Formulario 210 - the individual income tax return, where the US dividend and any realised gain are reported.
- Formulario 160 - the declaración de activos en el exterior, a separate annual filing covering foreign assets, submitted electronically.
Form 160 is driven by a threshold set in UVT (unidad de valor tributario), Colombia’s inflation-indexed accounting unit, rather than a fixed peso figure. For 2026 the DIAN set the UVT at COP 52,374, which puts the numbers here:
| Trigger | In UVT | In 2026 pesos |
|---|---|---|
| Must file Form 160 (foreign assets held at 1 January) | 2,000 UVT | COP 104,748,000 |
| Single asset that must be itemised rather than aggregated | 3,580 UVT | COP 187,498,920 |
Because the threshold is fixed in UVT and the UVT is re-set every year, the peso line moves annually on its own. An account that sat comfortably below the filing threshold last year can cross it without you buying a single additional share - through the UVT revision, the dollar, or the market. Check the current year’s UVT rather than reusing last year’s peso figure.

Your Next Steps as a Colombian Resident
Before you place the first trade from Colombia:
- Settle your residency status first - more than 183 days in any rolling 365 makes you resident, and nothing on the Colombian side of this guide applies until it does
- Expect 30% US dividend withholding with no treaty reduction - file W-8BEN anyway to certify status and avoid backup withholding
- Track acquisition dates per lot carefully - the 2-year threshold is the difference between a 15% ganancia ocasional rate and ordinary progressive rates up to 39%
- Record the TRM on each purchase date, not just the year-end rate - foreign assets are carried at the rate at initial recognition
- Check whether your foreign assets at 1 January cross 2,000 UVT (COP 104,748,000 for 2026), which triggers Formulario 160 on top of your Formulario 210
- Report US dividends as ordinary income (0%-39% progressive rates) on your Colombian return, since no preferential rate applies to foreign dividend income the way it does to long-held capital gains
- Report worldwide investment income to DIAN regardless of whether funds are repatriated to Colombia
- Verify current onboarding requirements with Interactive Brokers or eToro yourself
The Last Word on Colombia
One thing to watch: the 15% ganancia ocasional rate is not a fixture. It was 10% until Law 2277 of 2022 raised it, and a tax reform debated in late 2025 proposed taking it to 30% - which would erase most of the advantage the two-year rule currently buys. That was a proposal rather than enacted law, and proposals in Colombia are frequently amended or dropped, so confirm the rate in force for your filing year before you plan a sale around it. A rate that has already moved once in this decade can move again.
No treaty means the 30% US withholding on dividends is fixed - there’s no form that improves it. On the Colombian side, the two-year holding period is the single most consequential number in this guide: it’s the line between a 15% flat ganancia ocasional rate and ordinary progressive taxation reaching 39%, a far bigger gap than the more modest holding-period distinctions found elsewhere in this series. Getting that timing right is worth more than almost any other planning decision covered here.
None of this is advice on investing from Colombia for your own circumstances. No comprehensive US-Colombia income tax treaty exists at the time of writing. Colombian personal income tax brackets and the ganancia ocasional rate can change annually. A qualified Colombian tax advisor should review your specific position before you act.
