Knowing how your casino winnings get taxed is an aspect of playing responsibly. At Casoo Casino, we want you to have clear, accurate tax information before you make a bet. We operate under a recognised international licence and serve players in Portugal in full compliance with the applicable rules. This page outlines the tax obligations that may result from your activity on our platform—whether you’re a player or an affiliate. We’ll explain Portugal’s tax rules, your reporting duties, and how Casoo Casino supports your compliance. Our aim is simple: you experience the games, and you understand precisely what your fiscal responsibilities are, with no unnecessary stress.
How Portugal Imposes Tax on Gambling Winnings
Portugal imposes tax on online casino winnings from operators licensed in the EU or EEA under the Personal Income Tax Code (Código do IRS), treating them as “jogos de fortuna ou azar”. The rate is a flat 28% on your net annual gain—total prizes collected minus total amounts wagered during the tax year. Casoo Casino does not retain any tax from your withdrawals or account balance. The duty for calculating, declaring, and paying the tax is entirely yours. We recommend you keep a detailed log of all deposits, wagers, and withdrawals throughout the year. The Portuguese Tax Authority may ask for supporting documents if you’re ever audited.
Getting organised early saves time and reduces mistakes when you file your annual return. The tax isn’t calculated per session or spin. Instead, the annual aggregation method balances losing days against winning ones, which often works in your favour. This tax only applies to net gains, so if your total stakes exceed your total prizes, you owe nothing for that year. Still, keep all records so you can show your position if asked. Our platform gives you a clear, itemised transaction history you can export anytime—exactly the documentation you need to back up your declaration.
Practical Steps for Filing Your Tax Return
When tax season begins in April, export your full transaction history for the previous year. Ensure that it contains all deposits, bonuses, wagers, and withdrawals. Determine your net gain using the annual method. In the IRS portal, go to Annex G and enter the net gain in the field for foreign gambling income; the system charges the 28% rate. If you have no gain, bypass this section but retain your records. Notify our support team right away if you spot any discrepancies, and we’ll provide corrected data.
For affiliate income, utilize Annex B (individual) or Annex C (company). Declare gross commissions and deduct eligible expenses. If you’re VAT-registered, send the periodic VAT return even if no VAT is due. Create calendar reminders for deadlines (monthly VAT and the annual IRS deadline at the end of June) to escape fines. We can’t file for you, but we provide the data you need to fill out returns accurately and on time.
Tax Withholding and Reporting Obligations for Players Obligations
Numerous players believe the operator automatically deducts tax for them. At Casoo Casino, we apply no withholding tax to withdrawals. The Portuguese tax system assigns the responsibility firmly on you to report gambling income. Every year, when you complete your annual IRS declaration, you need to include your net casino winnings in the correct annex. The relevant annex for gambling income is Annex G, where you declare capital gains and other investment income, but winnings from foreign operators are placed under a dedicated code. We advise you to check the latest IRS instructions or consult a tax professional to make sure you use the correct field, because codes may change between tax years.
Failing to declare taxable gambling income may result in penalties, interest on unpaid tax, and in serious cases, criminal proceedings for tax evasion. The Portuguese Tax Authority has broadened its data-sharing agreements with international financial institutions and payment processors, so large or frequent casino transactions are increasingly visible than ever. Even when you play only now and then, we urge you to keep accurate records and provide a truthful return. The 28% special rate is applied to the net gain. If your total stakes surpass your total prizes, you have no tax liability, but you still need to be able to show that if asked. Our platform provides a clear, itemised transaction history you can export anytime.
Transnational Considerations and Taxation in Two Countries
Since Casoo Casino is licensed in Curaçao and you’re a Portuguese tax resident, dual taxation isn’t an issue. Portugal’s tax treaty with the Netherlands covers Curaçao, so gambling winnings are taxable only in Portugal. We do not deduct any Curaçao tax. Affiliate commissions are also taxed solely in Portugal. However, if you get commissions into a foreign bank account or e-wallet, you need to report that account on your IRS return. Not disclosing it can result reddit.com in severe penalties. This setup eliminates any risk of double taxation and simplifies your obligations.
Licensing and Supervisory Framework at Casoo Casino
Casoo Casino runs under a remote gambling licence from the Government of Curaçao, a jurisdiction known for robust regulatory standards. Curaçao is not an EU member, but the authorisation allows us to accommodate players in Portugal under the free movement of services within the European digital single market, as long as we comply with local consumer protection and anti-money laundering rules. Independent testing agencies audit our operations regularly to check game fairness, random number generator integrity, and the protection of player funds. We also follow strict know-your-customer and anti-money laundering protocols that correspond to Portuguese legal requirements for financial transparency.
Since our permit is not from the Portuguese gambling regulator (SRIJ), the tax handling of your winnings adheres to the rules for foreign-licensed operators casoo.pt. The Portuguese tax code specifically covers winnings from EU and EEA-licensed operators, and the Curaçao authorisation qualifies under international agreements Portugal respects. Every player can view a full transaction history (deposits, bonuses, wagers, and withdrawals) right from their account dashboard. That data is crucial for filling in the required annexes on your IRS declaration. We encourage you to download your statements regularly and save them safely. They’re your primary proof of gambling activity for tax purposes.
Taxation on Associate Earnings from Casoo Casino
If you become part of the Casoo Casino affiliate programme, the revenue you receive from referring players qualifies as business or occupational income under Portuguese tax law. According to how you organize your activity, you might have to sign up as a self-employed worker with the Portuguese Tax Authority and issue electronic invoices for the commissions you receive. The tax rate on affiliate earnings is based on the progressive IRS brackets if you are an individual, or the corporate income tax rate if you operate through a company. You may also be obliged to charge VAT on your services if your annual turnover surpasses the exemption threshold, currently €14,500 for 2024 (subject to annual updates).
We disburse affiliate commissions monthly in euros through several protected methods, and we don’t withhold any Portuguese tax from your payments. You’ll have a dedicated dashboard to follow referred players, earnings, and payment history. We suggest consulting a qualified accountant or tax advisor in Portugal to find the most efficient legal structure. Many partners opt for the simplified regime, where only a percentage of gross income is taxable. Others set up a limited company to take advantage of lower corporate rates and broader expense deductions. Your own circumstances will influence the best route, so professional advice is essential.

Documentation Best Practices for Portuguese Players
Monthly Data Export and Review
We advise downloading your Casoo Casino transaction history at the end of each month and keeping the files in a dedicated folder on your computer or cloud storage. The export features date, time, transaction type, amount, and resulting balance, so you have a thorough audit trail. Beside the casino records, keep copies of your bank statements or e-wallet statements displaying deposits to and withdrawals from your casino account. These external records confirm the casino data and give you an additional layer of proof that your reported figures are accurate. If you use multiple payment methods, gather all statements in one place so nothing gets missed.

Update it monthly so you’re not struggling to reconstruct a full year of data at the last minute.

Affiliate Program: Regulatory and Tax Aspects
Before you join our affiliate programme, be aware of the legal and tax implications. You establish a contractual relationship regulated by our terms and conditions, and your promotional activities must comply with Portuguese advertising laws—including responsible gambling messaging and the ban on targeting minors. We supply approved marketing materials, but you must use them in a way that respects local regulations. On the tax side, all commission income must be declared to the Portuguese Tax Authority, and you may be required to register as a self-employed professional before you obtain your first payment.
The tax treatment depends on whether you act as an individual or through a legal entity. For individuals, the income is classified under Category B of the IRS. You have the option between the simplified regime (where only 75% of gross commissions are taxable, with the rest treated as presumed expenses) and the organised accounting regime, which enables you to deduct actual costs like hosting, advertising, and software. If your expenses are high, organised accounting might be more beneficial. We recommend running a projection with a tax advisor to see which regime cuts your overall tax burden. Register early and issue invoices as required to stay compliant.
How to Calculate Your Assessable Casino Income
Calculating your taxable income is easy. Collect all deposit records and total wagers for the tax year (1 January to 31 December). Sum up all prizes you withdrew or that stay as a withdrawable balance. Net gain = prizes minus wagers. If the result is positive, apply the 28% rate. If it’s below zero, no tax is owed, but retain your records anyway. Don’t calculate per session; the annual aggregation offsets losing days against winning ones, which often works in your favour. Keep in mind to include all converted bonuses as prizes, because the Tax Authority views bonus money converted to cash as part of your winnings.
For example, assume you deposit €5,000, wager €12,000, and receive €14,000 in prizes. Your net gain is €2,000, and the tax due is €560. Ensure to include all bonuses that have been converted into withdrawable cash, because the Tax Authority views them as prizes. Our bonus history indicates exactly how much was awarded and converted, which aids you put together complete figures. Use that data to ensure your calculations are precise and you report the correct net gain on your return.

Value Added Tax and Further Taxes on Services on Gambling Services
Under EU VAT rules, gambling services are exempt, so you pay no VAT on stakes or account fees. The only tax on winnings is the special 28% IRS tax. For affiliates, VAT may be applicable if you are registered and your turnover surpasses the €14,500 threshold. In that case, you are required to charge 23% VAT on commission invoices. Because Casoo Casino is outside the EU, the reverse charge mechanism may allow you produce invoices without VAT if you record the business-to-business supply. We provide our company details for compliant invoicing. Get professional advice to deal with this correctly.

Updates to Portuguese Tax Law and Their Impact
Tax legislation changes, and the Portuguese government has discussed adjusting how online gambling is taxed as the market grows. At the time of writing, no definitive changes have been enacted, but we monitor legislative developments closely and will update this page if new rules come into force. We urge you to check the Portuguese Tax Authority’s official website or subscribe to our newsletter for announcements.
