Online Casino Licensing in Portugal: What the SRIJ Actually Requires

Portugal does not issue one universal online gambling licence. Games of chance (casino-style games including slots, roulette, blackjack and poker), sports betting, and other approved formats each require their own separate SRIJ licence, and land-based and online licences are entirely distinct. Operators must also provide a €500,000 guarantee per licence to cover player liabilities. There is a genuine open question worth flagging here: some sources describe live-dealer online casino games specifically as currently prohibited in Portugal pending regulatory review, while others describe online casino games generally as licensable without that carve-out. Given that conflict, check the SRIJ’s current published rules directly for the up-to-date position on live-dealer games specifically, rather than assuming either way.

Check an operator directly against the SRIJ’s current published list of licensed operators before depositing. A licence from another jurisdiction does not make an operator licensed in Portugal, and the exact count of licensed entities changes as licences are granted, renewed or revoked — SRIJ’s own list is the authoritative current source, not a fixed number cited in an article.

This is an important difference from several other countries covered in this section. According to SRIJ, players who bet on unlicensed platforms face their own penalties: an administrative fine (contraordenação) of €2,500 to €25,000 for illegal online betting, or up to six months’ imprisonment plus a fine for illegal land-based gambling. Operators face substantially harsher criminal penalties — up to five years’ imprisonment and fines running to hundreds of day-fines — but the player is not exempt from consequences here the way they are in some other jurisdictions.

Beyond the player-side penalties above, SRIJ enforcement against unlicensed platforms has intensified: in the second quarter of 2025 alone, SRIJ issued 97 cease-and-desist orders and requested blocking of 110 unlicensed websites, part of a total exceeding 1,500 blocked illegal sites since the market opened in 2015. In March 2026, SRIJ ordered a nationwide ISP block of the prediction market Polymarket, treating it as unlicensed gambling. SRIJ also works with payment processors to disrupt transactions to unlicensed platforms.

Portugal taxes gambling at the operator level, not the player level, through the Imposto Especial de Jogo Online (IEJO): a progressive 15% to 25% of gross gaming revenue for casino games as revenue grows, and 8% to 16% of total stakes for sports and horse-race betting. Player winnings from a licensed operator are not separately taxed or declared — what you receive is already the net amount. This tax-exempt treatment is specific to SRIJ-licensed play; it does not automatically extend to winnings from an unlicensed offshore platform, so that is not something to assume without checking current guidance, particularly since the exemption is generally understood to apply to recreational players rather than anyone treating gambling as a primary professional income source.

Licensed operators may currently advertise, subject to Article 21 of Portugal’s Advertising Code and SRIJ guidance, while unlicensed operators are barred from advertising entirely. As of 2026, Portugal’s parliament has been actively debating further restrictions, including possible bans on influencer endorsements and sports sponsorships, with binding legislation expected by the end of the year. Treat any claim about the final shape of these rules as provisional until that legislation is actually finalised.

SRIJ administers a national self-exclusion register connected to every licensed operator, so registering blocks a player across the whole licensed market rather than site by site. Linha 1414 operates as a national support line for anyone concerned about gambling, separate from the self-exclusion mechanism itself.

Given the criminal penalties attached to promoting unlicensed gambling in Portugal, the administrative penalties that apply directly to players using unlicensed platforms, and the fact that none of the internationally licensed casinos in our own data hold an SRIJ licence, we are publishing this page as a factual explainer rather than a recommendation list.
