You’ve just matched five numbers on EuroMillions, or a roulette night at Casino Estoril went better than planned. Now you’re wondering how much Portugal will take, whether you need to file anything, and what your bank will ask when the money lands. This guide covers how lottery, casino, and online betting winnings are taxed for residents and visitors in Portugal.

How Portugal Taxes Gambling Winnings

I remember the first time a Portuguese friend handed me a Raspadinha, the scratch card sold at every café counter and kiosk. Mine was a dud. I still asked her what would have happened if I’d won big. She shrugged and said, “Santa Casa takes its cut, and you keep the rest.” That shrug turned out to be a fairly accurate summary of the system. The details matter, though, especially if you’re a foreigner trying to fit this into your own tax picture.

Portugal does not treat all gambling the same way. The rules depend on who runs the game. State-run games are handled one way. Licensed online casinos and betting sites are handled another way. Anything outside the licensed system sits in murkier territory.

State Social Games and the Stamp Duty Rule

The State social games are run by Santa Casa da Misericórdia de Lisboa under the Jogos Santa Casa brand. They include:

• EuroMillions, called Euromilhões locally
• Totoloto
• Lotaria Clássica and Lotaria Popular
• Raspadinha

Prizes from these games are not taxed through your income tax return. They are subject to Stamp Duty, known as Imposto do Selo. Item 11.4 of the Stamp Duty General Table on the Portal das Finanças sets the rule. As of October 2026, 20% applies only to the part of a prize above EUR 5,000.

That last detail confuses newcomers the first time they read it. The 20% is not charged on the whole prize. The first EUR 5,000 is untouched. Only the portion above that line is taxed.

How the Calculation Works in Practice

The tax is withheld at source, so you never pay it yourself. Santa Casa deducts it before the money reaches you. To estimate your net prize:

1. Take the gross prize amount shown for your winning ticket.
2. If the prize is EUR 5,000 or less, you keep the full amount.
3. If it is above EUR 5,000, subtract EUR 5,000 to find the taxable portion.
4. Multiply that taxable portion by 20% to get the Stamp Duty withheld.
5. Subtract the Stamp Duty from the gross prize. The result is what lands in your account.

Picture a retired couple in Tavira who share a Totoloto syndicate with neighbours. A modest win split among the group is often below the threshold for the ticket holder, so there’s nothing to worry about. A bigger EuroMillions hit is a different story. The headline figure on the news will be noticeably larger than what reaches the bank. Knowing this in advance stops a lot of disappointment.

Do You Declare Lottery Prizes on Your IRS Return?

Because Stamp Duty is withheld at source on Santa Casa prizes, the prize itself is generally settled. It doesn’t become a separate line of income on your annual return. For many expats, that’s a pleasant surprise. Back home, they may have been used to declaring winnings as income.

The money stops being tax-free the moment it starts earning. Interest on a savings account, dividends from investments, or gains on property you buy with the prize all fall under the normal rules. See Portuguese Taxes for Expats: IRS, Tax Residency, and Filing Deadlines for how that ongoing income is reported.

Casinos, Online Betting, and Foreign Games

Here’s where foreigners usually need the most clarity. Portugal has a well-developed regulated gambling market. Physical casinos operate in places like Estoril, Lisbon, Espinho, Póvoa de Varzim, and Vilamoura, and there is a licensed online sector alongside them.

Licensed Online Casinos and Sports Betting

The Stamp Duty General Table contains no item for winnings from licensed online casinos or sports betting. Item 11.4 covers only the State social games. Licensed betting sites therefore do not withhold Stamp Duty from your winnings.

The tax is collected at the operator level instead. According to SRIJ, the gambling regulator under Turismo de Portugal, licensed online gambling operators pay the special online gambling tax, the imposto especial de jogo online, or IEJO. That information comes from a page updated on 3 March 2026, as of October 2026. For you as a player, a win on a licensed Portuguese site is not hit by the 20% Stamp Duty.

Licensed operators display their SRIJ licence on their sites. Checking that licence matters for more than tax reasons. It’s also your main protection if a payout dispute arises.

Physical Casino Winnings

Land-based casinos operate under concessions and are taxed through the gaming tax regime that applies to the operator. The Stamp Duty item for prizes covers the State social games, not casino tables or slot machines. A good night at the blackjack table in Estoril does not trigger the Stamp Duty rule that applies to EuroMillions.

Keep any documentation the casino provides when you cash out a large amount, such as payout slips or cheque records. It won’t usually affect your Portuguese tax. It can matter a great deal when your bank asks where the money came from.

Unlicensed Sites, Crypto Casinos, and Foreign Lotteries

This is the grey zone. Winnings from operators that are not licensed in Portugal don’t fit neatly into either of the systems above. That includes offshore casino sites, crypto gambling platforms, and lottery tickets bought in another country. Portuguese tax residents are taxed on worldwide income, so unexplained or foreign-sourced winnings may need to be assessed under the general income tax rules. Treatment varies with the facts.

A common scenario: a digital nomad in Lisbon wins on a crypto casino and withdraws to an exchange like Binance. They then convert to euros and send the money to a Portuguese bank. Every step leaves a trail. The tax analysis may also involve the crypto itself, which How Are Crypto Gains Taxed in Portugal? covers. If this is you, don’t guess. Get an accountant to look at the full chain of transactions before you file.

Foreign lottery prizes are different again. The country where you bought the ticket may withhold its own tax. Whether Portugal taxes the prize as well depends on your residency status and on any treaty with that country.

What to Do After a Big Win in Portugal

Winning is the fun part. The admin afterwards is where expats tend to trip up, usually because of banks rather than the tax office.

Practical Steps Once You Have the Money

1. Sign the back of your Santa Casa ticket or keep your online account details safe. The ticket is the proof of ownership.
2. Claim through the official channel. Smaller prizes are paid at authorised agents. Larger ones are processed by Santa Casa directly.
3. Keep every payment document Santa Casa or the casino gives you. This is your source-of-funds evidence.
4. Tell your bank before a large deposit arrives. Portuguese banks follow anti-money-laundering rules and may freeze or question unexpected transfers.
5. If you share the prize with people outside your close family, check whether gift Stamp Duty applies. Wealth Tax, Inheritance Tax, and Stamp Duty (Imposto do Selo) in Portugal explains the gifting rules.
6. Book a session with an English-speaking accountant before you invest or move the money. Finding an English-Speaking Certified Accountant (Contabilista Certificado) has tips on choosing one.

Moving Winnings Abroad

Plenty of expats want to send part of a windfall home, perhaps to pay off a mortgage in the UK or help family in the US. If you use a transfer service like Wise, you’ll see the exchange rate and fee structure before you confirm. Check its own pricing page for current figures. For large sums, expect compliance checks on both ends. Having your Santa Casa paperwork ready makes this painless. Transferring money out of Portugal: Limits and reporting rules for large sums goes through the reporting side in detail.

Americans have an extra layer to deal with. Portugal may have taken its Stamp Duty, but the US taxes its citizens on worldwide income. Your Portuguese-withheld prize may still need to be reported to the IRS back home. If the winnings sit in a Portuguese bank, account reporting obligations can also apply. Do I have to declare my foreign bank accounts to the Portuguese IRS? covers the Portuguese side of that question.

Investing the Prize Sensibly

Once the excitement fades, the question becomes what to do with the money. Some expats open an account with a broker like Trade Republic to put winnings into ETFs. Check the provider’s own page for current costs and product terms. Remember that dividends and gains from those investments are taxable in Portugal, even though the original prize wasn’t treated as income. Capital Gains Tax in Portugal: Property Sales, Stocks, and ETF Dividends explains how that works.

For larger sums, an independent adviser can save you from impulsive decisions. Wealth Management in Portugal: Finding English-speaking independent financial advisors is a sensible next read.

A Word on Tourists and Short-Term Visitors

If you’re on holiday and win on a Raspadinha bought at a Lisbon kiosk, the same Santa Casa rules apply to you. The withholding happens at source whatever your nationality. Your home country may still expect you to declare the prize, so check its rules before you fly home with a fat envelope. For licensed online play while visiting, the operator handles its own taxation. Your home tax authority remains the bigger question.
