Being aware of how your casino winnings are taxed is part of playing responsibly https://casoo.pt/legal-and-affiliates/. At Casoo Casino, we aim to provide you with clear, accurate tax information before you make a bet. We operate under a recognised international licence and cater to players in Portugal in full compliance with the applicable rules. This page addresses the tax obligations that might come from your activity on our platform—whether you’re a player or an affiliate. We’ll walk you through Portugal’s tax rules, your reporting duties, and how Casoo Casino helps you stay compliant. Our aim is simple: you have fun with the games, and you know exactly what your fiscal responsibilities are, with no unnecessary stress.
How Portugal Imposes Tax on Gambling Winnings
Portugal levies tax on online casino winnings from operators licensed in the EU or EEA under the Personal Income Tax Code (Código do IRS), classifying 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 withhold any tax from your withdrawals or account balance. The obligation for calculating, declaring, and paying the tax is entirely yours. We suggest 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 is time-saving and minimises mistakes when you file your annual return. The tax isn’t calculated per session or spin. Instead, the annual aggregation method nets 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.
Partnership Program: Regulatory and Taxation Factors
Before you join our affiliate programme, be aware of the legal and tax implications. You will enter a contractual relationship governed by our terms and conditions, and your promotional activities must follow Portuguese advertising laws—including responsible gambling messaging and the ban on targeting minors. We provide approved marketing materials, but you are required to use them in a way that adheres to local regulations. On the tax side, all commission income must be reported to the Portuguese Tax Authority, and you may need to register as a self-employed professional before you receive 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 may choose 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 may work out better. We suggest running a projection with a tax advisor to see which regime reduces your overall tax burden. Register early and issue invoices as required to stay compliant.
Taxation on Partner Commissions from Casoo Casino
If you become part of the Casoo Casino affiliate programme, the income you generate from recommending players is classified as professional or occupational income under Portuguese tax law. Depending on how you organize your activity, you might be required to register as a independent worker with the Portuguese Tax Authority and produce electronic invoices for the commissions you collect. The tax rate on affiliate earnings adheres to the progressive IRS brackets if you’re an individual, or the corporate income tax rate if you work through a company. You could also have to charge VAT on your services if your annual turnover surpasses the exemption threshold, currently €14,500 for 2024 (subject to annual updates).
We remit affiliate commissions monthly in euros through several safe methods, and we do not withhold any Portuguese tax from your payments. You’ll have a dedicated dashboard to track referred players, earnings, and payment history. We advise consulting a qualified accountant or tax advisor in Portugal to identify the most optimal legal structure. Many partners opt for the simplified regime, where only a percentage of gross income is taxable. Others establish 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.
How to Calculate Your Taxable Casino Income
Computing your taxable income is straightforward. Gather 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 above zero, apply the 28% rate. If it’s negative, no tax is owed, but keep your records anyway. Don’t calculate per session; the annual aggregation offsets losing days against winning ones, which often operates in your favour. Remember to include all converted bonuses as prizes, because the Tax Authority considers bonus money converted to cash as part of your winnings.
For example, imagine you deposit €5,000, wager €12,000, and gather €14,000 in prizes. Your net gain is €2,000, and the tax due is €560. Be sure to incorporate 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 helps you compile complete figures. Utilize that data to ensure your calculations are accurate and you report the correct net gain on your return.
Documentation Best Practices for Portugal-based Players
Monthly Export and Checking
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 includes date, time, transaction type, amount, and resulting balance, so you have a full audit trail. Alongside 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 back up the casino data and give you an further layer of proof that your reported figures are correct. If you use multiple payment methods, gather all statements in one place so nothing gets missed.
We also suggest creating a straightforward spreadsheet that summarises your annual activity. Include columns for total deposits, total wagers, total prizes, and the calculated net gain. Update it monthly so you’re not scrambling to reconstruct a full year of https://pt.wikipedia.org/wiki/Categoria:Jogos_de_azar data at the last minute. If you’re in our affiliate programme, keep a distinct ledger for commission income—date each payment was received, gross amount, and any expenses you plan to deduct. Good record-keeping keeps you tax-compliant and aids you analyze your playing patterns and affiliate performance, contributing to smarter decisions and better bankroll management. Our support team is always accessible to help you find specific transactions if you run into trouble with the export function.
Authorisation and Regulatory Framework at Casoo Casino

Casoo Casino operates under a remote gambling licence from the Government of Curaçao, a territory known for stringent regulatory standards. Curaçao is not an EU member, but the licence allows us to cater to players in Portugal under the free movement of services within the European digital single market, as long as we meet local consumer protection and anti-money laundering rules. Independent testing agencies inspect our operations regularly to verify game fairness, random number generator integrity, and the protection of player funds. We also implement strict know-your-customer and anti-money laundering protocols that correspond to Portuguese legal requirements for financial transparency.
Since our licence is not from the Portuguese gambling regulator (SRIJ), the tax processing of your winnings complies with the rules for foreign-licensed operators. The Portuguese tax code explicitly covers winnings from EU and EEA-licensed operators, and the Curaçao authorisation qualifies under international agreements Portugal recognises. Every player can retrieve 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 keep them safely. They’re your primary proof of gambling activity for tax purposes.
Withholding Tax and Reporting Obligations for Players Obligations
Numerous players assume the operator deducts automatically tax for them. At Casoo Casino, we don’t apply withholding tax to withdrawals. The Portuguese tax system assigns the responsibility directly on you to report gambling income. Annually, when you file your annual IRS declaration, you need to include your net casino winnings in the right annex. The particular 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 recommend you to consult the latest IRS instructions or work with a tax professional to ensure you use the correct field, because codes change between tax years.
Failing to declare taxable gambling income can result in penalties, interest on unpaid tax, and in serious cases, criminal proceedings for tax evasion. The Portuguese Tax Authority expanded its data-sharing agreements with international financial institutions and payment processors, so large or frequent casino transactions are more apparent than ever. If you play only now and then, we strongly advise you to keep accurate records and provide a truthful return. The 28% special rate applies to the net gain. If your total stakes surpass your total prizes, you carry no tax liability, but you must still to be able to show that if asked. Our platform offers a clear, itemised transaction history you can export anytime.
International Considerations and Double Taxation
Since Casoo Casino is licensed in Curaçao and you’re a Portuguese tax resident, taxation in two countries 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 exclusively in Portugal. However, if you obtain commissions into a foreign bank account or e-wallet, you are required to report that account on your IRS return. Not disclosing it can result in severe penalties. This setup eradicates any risk of double taxation and eases your obligations.
VAT and Other Indirect Taxes on Gaming Services
Under EU VAT rules, gambling services are exempt, so you incur no VAT on stakes or account fees. The only tax on winnings is the specific 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 let you produce invoices without VAT if you document the business-to-business supply. We provide our company details for compliant invoicing. Get expert advice to manage this correctly.
Essential Guide for Filing Your Tax Return
When tax season begins in April, download your full transaction history for the previous year. Check that it includes all deposits, bonuses, wagers, and withdrawals. Compute 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 uses the 28% rate. If you have no gain, omit this section but retain your records. Contact our support team right away if you detect any discrepancies, and we’ll furnish corrected data.
For affiliate income, utilize Annex B (individual) or Annex C (company). Report gross commissions and deduct eligible expenses. If you’re VAT-registered, submit 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 prevent fines. We can’t file for you, but we give the data you need to finish returns accurately and on time.
Casoo Casino’s Pledge to Safe and Regulated Play
We provide tools to support your money management: deposit caps, loss caps, and session alerts. These enable you regulate spending and make tax filings simpler. We explain bonus terms clearly so you avoid reporting errors. Our customer support team is prepared to answer your questions without promoting risky behaviour. We run a strict anti-money laundering programme that includes ID verification and transaction oversight, aligned with FATF standards and Portuguese law. External auditors review our operations regularly, checking asset safety and fair play.
Frequent Errors to Avoid When Declaring Casino Income
Many players do preventable mistakes when declaring online casino income. The most typical ones are:

- Not reporting small net gains, thinking only large amounts count.
- Reporting gross withdrawals as income without deducting total wagers.
- Considering deposits as taxable income (they aren’t).
- Neglecting to include converted bonuses as part of your prizes.
- Combining personal and gambling transactions in the same account without a clear separation.
Using a dedicated e-wallet or a separate bank account for all casino transactions gives you a clean paper trail and minimizes audit stress. If you’re ever in doubt about a specific transaction, talk to a Portuguese tax professional who knows the gambling sector. The cost of professional advice is tiny compared to the potential penalties for filing incorrectly.
Amendments to Portuguese Tax Law and Its 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 track 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. One area under discussion is a potential centralised reporting system that would require foreign operators to share player data directly with the authorities. If that happens, accurate self-reporting would become even more critical. Casoo Casino is ready to comply with any lawful data-sharing obligations and will tell you in advance about any changes to our reporting practices. Your diligence in meeting tax obligations supports the integrity of the online gaming industry and helps keep a positive regulatory environment for everyone involved.
