Casino Winnings Tax in Colombia: What Gets Withheld

In-depth analysis

What matters about Casino Winnings Tax in Colombia: What Gets Withheld

Colombia does not treat a casino win the way it treats a salary. It goes in through a different door, the one marked ganancias ocasionales, occasional gains. Article 304 of the Estatuto Tributario puts lotteries, raffles, bets and anything similar into that category, and Article 317 gives all of them a single flat rate of 20%, with no brackets: win a hundred thousand pesos or a hundred million, the percentage is identical. Article 306 settles who collects it, and that is the part worth remembering. The tax is withheld at source, at the moment of payment or credit, by the payer. A Coljuegos-licensed operator acts as the withholding agent. The same rule applies word for word to sports betting.

The detail almost no guide bothers with sits in Article 404-1: withholding is only applied when the individual payment or credit exceeds 48 UVT. The UVT is the tax unit the DIAN re-prices every December, and for 2026 it was fixed at $52,374 by Resolution 000238, which puts the floor at $2,513,952. Under that figure the operator deducts nothing at all, and that is where nearly all the confusion starts. Worth knowing, too, that the rate is under debate: the tax reform bill filed on 20 July 2026 proposes changing it. Until that passes, 20% is what applies.

What the 20% is calculated on, and what it is not

The withholding is applied to the payment, not to your profit. If a $3,000,000 prize came off a $2,800,000 stake, the base is still $3,000,000: the code does not net off what you risked, and it certainly does not net off what you lost earlier in the week. The threshold is also tested payment by payment, not per session or per day: every prize is measured on its own against the same 48 UVT.

That last row matters more than it looks. The tax is triggered when the prize is paid or credited to your gaming account, not when you move the money to your bank. A large withdrawal does not create a withholding by itself, so if your cashier shows a deduction exactly at cash-out, ask what it is before assuming the DIAN took it. Timings and rail fees are a separate subject, covered in withdrawals.

48 UVT is a floor for withholding, not an exemption

Here is the mistake that gets repeated in every forum thread: assuming that if nothing was withheld, nothing is taxable. Article 404-1 governs the withholding agent, not the winner. It tells the operator when it must deduct; it does not say small prizes stop being occasional gains. Two different questions.

For most players the two answers collapse into one, because the rate withheld and the rate of the tax are the same 20%. If it was withheld, the tax on that prize is settled. If you are also required to file a return, the prize and the withholding both go into it, and the withholding is subtracted as tax already paid. The gap opens when several prizes were paid without any withholding and you do turn out to be a filer: that income exists whether or not anyone deducted it along the way.

There is also a back door that catches frequent players off guard. One of the Article 594-3 tests that forces you to file is total bank deposits and financial movements of 1,400 UVT in the year, roughly $73,323,600 at the 2026 UVT. Every casino withdrawal that landed in your account counts towards it, whether it was profit or simply your own money coming back. Finishing the year flat does not help: what is measured is how much passed through the account, not how much stayed.

Withholding, 4x1000 and fees are three different deductions

When a player says money went missing from a withdrawal, three unrelated things can be happening. Telling them apart is most of the work.

A practical way to read your statement: if the deduction is exactly 20% of a payment above $2,513,952, it is the withholding. If it is 0.4% of a sum moved out of your bank account, it is the 4x1000. If it matches neither, it is a fee, and a fee is something you can query.

Unlicensed casinos withhold nothing and certify nothing

A site without a Coljuegos licence is not a withholding agent in Colombia. It does not take the 20%, it reports nothing to the DIAN and it cannot issue you a certificate. That feels like an advantage for roughly one year, right up to the point where you have to explain where the money came from.

The check that prevents all of this takes two minutes before you deposit anywhere: verify the licence against the Coljuegos register, not against the badge the site put in its own footer. If you would rather start from a list already checked, see operators with a current licence.

What the operator pays, and why 2026 was a strange year

It is worth saying where the money the casino hands out comes from, because it explains everything else. A licensed operator keeps the GGR: everything staked minus every prize paid. On that figure it pays Coljuegos exploitation rights, and those revenues are earmarked by law for health: that is the monopoly Ley 643 de 2001 set up. Regulation also requires games run over the internet to hold a minimum return to player, a floor under RTP. There is no ceiling over the house: the margin is always there, it is why the business exists, and the licence only fences it in and taxes it.

On top of that stable arrangement, 2026 added noise. Decreto 1474 de 2025, issued under December's economic emergency, extended the general 19% VAT to online gambling, and several operators passed the cost straight to the player deposit. In April 2026 the Constitutional Court struck it down with retroactive effect in Sentencia C-079 de 2026 and ordered the revenue returned. Then came Decreto Legislativo 240 of 12 March 2026, creating a transitional 16% national consumption tax on games operated exclusively online: it is filed every two months, and questions are still open about who ultimately bears it and what base it is worked out on. None of that is your occasional-gains tax, and none of those percentages comes out of your prize. It can, however, change what you see in the cashier when you deposit.

That is why we read the cashier and the account history as closely as the game catalogue when we compare casinos: it is where you find out whether an operator is honest about deductions. The method is set out in how we review.
