Colombia has never signed a comprehensive income tax treaty with the United States, so the full 30% US withholding applies to dividends with no reduction available. But the number that actually determines a Colombian investor’s after-tax return on a US stock sale is a single date: whether the position was held for two years or more.
This guide covers what you can buy, the withholding reality, and exactly how Colombia’s two-year rule works.
Everything here is verified from official sources for 2026.
Meet Camila
Camila is 29, lives in Medellín, and works in logistics. She has COP 40,000,000 saved and wants to start investing in US equities. She has heard Colombia has no tax treaty with the US and assumes that means the tax situation is simply worse across the board. Part of that is true - but the more important number for her actual return is not the treaty (or lack of one), it is how long she holds each position.
Step 1: Your Investable Universe From Colombia
Colombia is not covered by PRIIPs, the EU rule that forces European investors into UCITS wrappers instead of US-domiciled funds. Camila can buy VOO, VTI, and QQQ directly through a broker offering US market access.
Step 2: No Treaty - The 30% Is Fixed
Without a treaty, Form W-8BEN does not reduce US dividend withholding the way it does in treaty countries - it still certifies non-US person status and prevents backup withholding, but the number on Camila’s dividend statement will read 30%, with nothing to optimize.
Capital gains: the US generally does not tax capital gains realized by a non-resident alien on US securities under domestic law, independent of treaty status - this part does not depend on a US-Colombia treaty existing at all.
For the full mechanics, see our US-Colombia tax treaty guide.
Step 3: Colombia’s Side - The 2-Year Line
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 very different regimes depending on holding period:
Held 2 years or more: the gain is classified as ganancia ocasional and taxed at a flat 15% - a preferential rate well below Colombia’s top marginal bracket.
Held less than 2 years: the gain is taxed as ordinary income at Colombia’s progressive rates, running from 0% up to 39% for tax residents.
The gap is large. 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%. This makes tracking the exact acquisition date of each lot genuinely worth the discipline, rather than treating it as an approximation.
A worked illustration of the stakes: Camila buys $10,000 of VOO and, 22 months later, it’s worth $13,000 - a $3,000 gain. If she sells at that point (two months short of the two-year mark) and is in Colombia’s top bracket, she could owe up to $1,170 in Colombian tax on that gain (39% ordinary rate). If she instead waits two more months to cross the two-year threshold, the same $3,000 gain is taxed at the flat 15% ganancia ocasional rate - $450. That’s a $720 difference on the exact same dollar amount of gain, driven entirely by a two-month timing decision. This is precisely why per-lot acquisition-date tracking matters more in Colombia than in almost any other country covered in this series - the financial stakes of getting the date wrong, or selling impatiently, are unusually concrete and calculable.
Foreign dividends - including US dividends - are taxed at Colombia’s ordinary progressive rates (0%-39%), the same schedule that applies to short-term gains. There is no preferential rate for dividend income analogous to the ganancia ocasional treatment available for long-held capital gains.
Step 4: W-8BEN: The Form That Sets Your Rate
Form W-8BEN still matters even without a treaty rate to claim - it certifies Camila’s non-US status to her broker and avoids the risk of backup withholding, a higher default rate applied to accounts without valid tax documentation.
Step 5: Broker Selection for Colombia Residents
Account opening is available to Colombian residents at Interactive Brokers (IBKR) and eToro. See our full IBKR review → · See our full eToro review →
Step 6: What Camila’s Portfolio Looks Like in Practice
Broker: Interactive Brokers, since cost matters more as the account builds.
Portfolio allocation:
- 80% VOO (S&P 500, bought directly)
- 20% VXUS (ex-US developed and emerging markets)
- Deliberately low-turnover: since Camila’s Colombian tax outcome hinges on how long she holds each position rather than on treaty relief, the allocation is built to be left alone rather than rebalanced actively
- W-8BEN filed to avoid backup withholding
Annual tax situation:
- 30% US withholding on dividends - her only US layer, since there is no treaty rate to reduce it
- US dividends reported and taxed at Colombia’s ordinary progressive rates (0%-39%)
- Any capital gains taxed at 15% (ganancia ocasional) if held 2+ years, or ordinary progressive rates up to 39% if sold sooner
She logs the exact purchase date of every lot she buys, since crossing the two-year mark before selling is the single biggest lever she has over her actual tax bill on this portfolio.
The Usual Mistakes Around Colombia
Selling just before the two-year mark. The difference between 15% and up to 39% is large enough that waiting a few extra weeks can matter significantly.
Assuming US dividends get a preferential rate like long-held capital gains. They do not - dividends are taxed as ordinary income at Colombia’s progressive rates.
Not tracking acquisition dates per lot. With Colombia’s two-year rule, approximate record-keeping can cost real money.
Skipping W-8BEN because there’s no rate benefit. It still matters for avoiding backup withholding.
What to Do First From Colombia
- Open a broker account. IBKR or eToro, both confirmed to accept Colombian residents.
- File your W-8BEN to avoid backup withholding, even without a rate reduction.
- The US-domiciled funds can be bought directly; UCITS versions are an EU requirement.
- Set up per-lot acquisition date tracking from your very first purchase, given how much the two-year threshold matters.
General information about Colombia - not a recommendation you should act on unaided. There is no comprehensive income tax treaty between the United States and Colombia as of this update. Colombian personal income tax brackets and the ganancia ocasional rate can change annually - consult a qualified Colombian tax advisor for advice specific to your situation.
Frequently Asked Questions
Can I buy VOO and QQQ directly as a Colombian investor? Yes. Nothing in Colombia mirrors PRIIPs, so US-listed stocks and ETFs are directly accessible through your broker.
Does filing W-8BEN reduce my US dividend withholding? No. Without a US-Colombia tax treaty, the 30% default withholding applies regardless. Filing it still matters because it prevents backup withholding.
How does Colombia tax my US stock capital gains? It depends entirely on holding period: 15% flat (ganancia ocasional) if held 2+ years, or ordinary progressive rates up to 39% if sold sooner.
How are my US dividends taxed in Colombia? As ordinary income at Colombia’s progressive rates (0%-39%) - there is no preferential rate for dividends the way there is for long-held capital gains.
Which brokers accept Colombian residents? Interactive Brokers and eToro are both confirmed to accept Colombian residents for account opening.
