Introduction: More Than Just a Lucky Spin
When you win big at an online casino, your first thought is celebration—not taxes. However, in Denmark, the legality and taxation of gambling winnings is a subject that deserves more attention than most players realize. For Danish residents, especially in 2025, understanding the rules around taxation on online casino winnings is critical—not just to stay compliant with the law, but also to maximize your earnings legally.
It becomes even more relevant when discussing the growing number of Danes who play on udenlandsk casino med Trustly—foreign-based platforms that may or may not fall within Danish tax laws, depending on their license status and payment channels.
This in-depth guide provides expert insights into the complexities of taxation on casino winnings in Denmark, focusing on licensed versus unlicensed platforms, cross-border play, reporting requirements, and what you can (legally) keep after hitting that jackpot.
Danish Gambling Law: A Short Overview
The foundation of how winnings are taxed starts with understanding how gambling is regulated in Denmark. Since 2012, the Danish Gambling Authority (Spillemyndigheden) has maintained a firm grip on the online gambling sector with a dual mission:
- Protect consumers and vulnerable groups
- Ensure fair, transparent, and taxed play within Danish jurisdiction
Any casino that wishes to legally offer services to Danes must be licensed by Spillemyndigheden. This ensures consumer protections, tax compliance, and data transparency, especially in connection with ROFUS (the Danish self-exclusion register) and AML (anti-money laundering) obligations.
Are Winnings from Danish Online Casinos Tax-Free?
The good news for Danish players is this:
Winnings from online casinos licensed in Denmark are tax-free for the player.
Here’s why:
- The casino operator, not the player, is responsible for paying taxes to the Danish government.
- Operators pay a 20% GGR (gross gaming revenue) tax, which is taken before any winnings are distributed to players.
- Since these winnings have already been “taxed at the source,” players are not required to declare them in personal income tax.
So if you’re playing at a Danish-licensed platform and hit a million kroner on a slot machine, you’ll get the full amount without owing Skat (the Danish tax authority) a single øre.
What About Foreign Casinos?
This is where things get more nuanced—and potentially risky.
If you play on a foreign casino that is not licensed in Denmark, the rules change depending on where the platform is licensed and your residency.
EU/EEA Licensed Casinos
Denmark follows the EU principle of the freedom to provide services across member states. This means if you’re gambling on a platform licensed in another EU/EEA country—such as Malta, Sweden, or Estonia—and it meets certain regulatory standards, your winnings may also be tax-free.
However, there’s a catch.
- The foreign casino must be subject to a regulatory regime comparable to Denmark’s, with sufficient consumer protection and transparency.
- If it is, then EU law overrides national tax rules, and you don’t have to pay tax.
- But if it’s not, or if there’s no license at all, your winnings become taxable income.
Outside EU/EEA
If the casino is based in a non-EU/EEA country, such as Curaçao or Costa Rica, and does not hold a Danish license, then all winnings must be declared and taxed as personal income.
That means:
- You must report the winnings on your annual tax return
- They are taxed at your personal income tax rate (can be up to 55% including top tax in Denmark)
- Failure to report can lead to penalties, back taxes, and interest
The Rise of Udenlandsk Casino med Trustly
With many players seeking faster payouts, fewer restrictions, or more diverse games, the use of udenlandsk casino med Trustly has exploded. Trustly—an instant bank transfer service—gives users a quick, anonymous way to deposit and withdraw funds without traditional credit card systems.
While these platforms are attractive, players must understand:
- Just because a casino accepts Trustly, doesn’t mean it’s licensed or tax-free
- Many of these casinos are based outside Denmark, sometimes even outside the EU
- Playing on such platforms may trigger tax obligations, even if the operator claims otherwise
Bottom line: convenience does not equal compliance. Trustly is a payment method—not a regulatory safeguard.
Case Study: Danish Player Wins 500,000 DKK on Foreign Platform
Let’s consider a real-world-style scenario.
Anders, a Danish resident, plays on a foreign platform based in Curaçao, which accepts Trustly. He wins 500,000 DKK on progressive slots and withdraws it successfully.
What are the consequences?
- Because the platform is not licensed in Denmark or the EU, the winnings are not automatically tax-free
- Anders is legally obligated to report the winnings as personal income
- If he’s in a 45% tax bracket, he may owe over 225,000 DKK in taxes
- If he fails to report it and is audited, he could face back taxes, penalties, and interest
Compare this with Anders playing on a Danish-licensed casino—he would keep the full 500,000 DKK, tax-free.
Do You Need to Report Winnings?
If you play on Danish-licensed platforms: No.
If you play on unlicensed platforms—especially outside the EU/EEA: Yes.
The Danish Tax Agency does not receive automatic reports from foreign casinos. However, with modern banking surveillance, unexplained large deposits can trigger audits.
You are responsible for reporting winnings honestly on your annual tax return. Failure to do so is considered tax evasion, not an oversight.
How to Stay on the Right Side of the Law
To avoid unwanted surprises, follow these steps:
1. Stick to Licensed Platforms
Check the official list of licensed online casinos on Spillemyndigheden’s website. If it’s not listed, think twice.
2. Keep Records of Foreign Play
If you play on a foreign platform:
- Save screenshots of games played
- Keep email confirmations
- Document withdrawal amounts and methods
- Record where the platform is licensed
This helps if you need to justify your earnings to tax authorities.
3. Consult a Tax Professional
Especially for high-value winnings, speaking with a Danish tax advisor is critical. They can help you:
- Evaluate if winnings are taxable
- Minimize your obligations legally
- Avoid future penalties
Misconceptions About Casino Taxes in Denmark
Many myths circulate in online gambling forums and Facebook groups. Let’s clarify a few.
Myth 1: You Don’t Pay Tax on Foreign Winnings If They’re Small
Wrong. Even if you win just 500 DKK, if it’s from a non-EU platform, it must be reported.
Myth 2: If You Use Crypto, It’s Invisible to Skat
Wrong. Cryptocurrency exchanges in the EU must report large transactions. Even peer-to-peer wallets can be tracked if linked to fiat withdrawals.
Myth 3: Trustly Means It’s Legal
False. Trustly is just a payment facilitator. It does not guarantee regulatory compliance or Danish licensing.
What Happens If You Don’t Report?
The Danish Tax Agency is thorough and proactive. If you fail to declare taxable winnings:
- You may face back taxes for up to 10 years
- Penalties of up to 60% of the undeclared amount
- In severe cases, criminal charges for fraud
Furthermore, repeated offenses can impact your eligibility for loans, mortgages, or even government employment.
Will Tax Laws Change in the Future?
As of 2025, there are ongoing discussions in the Danish Parliament to:
- Strengthen cross-border gambling regulations
- Increase cooperation with payment providers (like Trustly) to track unlicensed play
- Introduce automated player reporting systems for foreign licensed casinos
Some experts predict that by 2027, all winnings from outside Denmark will require real-time tax withholding—a shift that could end the current “grey zone” for foreign play.
Expert Opinion: Why the System Works
While some players find the Danish tax model restrictive, most international analysts agree: it offers a fair balance.
- Players enjoy tax-free winnings from trusted, regulated platforms
- Casinos bear the tax burden, leading to more transparent operations
- The market remains safe, legal, and socially responsible
This model is now being explored by Switzerland, Ireland, and parts of Germany, inspired by Denmark’s balance of freedom and control.
Conclusion: The Real Value of Playing Smart
Winning at an online casino should be exciting—not stressful. But unless you understand how taxes work in Denmark, that thrill could turn into confusion or worse.
Here’s what to remember:
- Play on Danish-licensed platforms for full tax exemption and legal safety
- Be cautious with udenlandsk casino med Trustly—they may feel legitimate, but still trigger tax duties
- If in doubt, consult a tax expert, especially for large winnings
- Keep detailed records of foreign gameplay and withdrawals
In 2025, online gambling is more accessible than ever. But with that freedom comes responsibility. Know the rules, follow the law, and you can enjoy your winnings with peace of mind—and a clean conscience.
And remember: in Denmark, the house may take a cut—but Skat always knows when the chips fall.
