Portugal has a structured online gambling framework regulated by SRIJ (Serviço de Regulação e Inspeção de Jogos), the Gambling Inspectorate under the Portuguese Tourism of Portugal authority. The Portuguese legal framework (Decree-Law No. 66/2015) licences domestic online casino, sports betting, and poker operators. Licensed domestic operators include PokerStars PT, bet365 PT, Betclic, Solverde Online, and others. Offshore operators without a SRIJ licence are prohibited from serving Portuguese players — SRIJ maintains a blacklist of unlicensed sites that Portuguese ISPs are required to block.
This guide covers the SRIJ regulatory framework, Portugal's blacklist and ISP blocking, the EUR deposit path for Portuguese players (MB Way, SEPA, Portuguese exchanges), Portuguese tax on gambling winnings (IRS), and practical guidance for Portuguese high-limit players. For the broader European context, see Europe regulatory overview and Spain guide. Full operator ranking at high roller crypto casinos.
Decree-Law No. 66/2015: Portugal's primary online gambling legislation, creating the SRIJ licensing framework. Licences are issued for online casino games, sports betting, and poker. The framework is open to private operators who meet financial and technical requirements — not a state monopoly. Multiple international operators hold SRIJ licences.
SRIJ Blacklist (Lista de Sítios Proibidos): SRIJ maintains a public blacklist of websites prohibited from offering gambling services in Portugal without a licence. Portuguese ISPs (MEO/Altice, NOS, Vodafone PT, NOWO) are required to block blacklisted domains. Offshore crypto casino domains are routinely listed. The blacklist is publicly accessible on srij.turismodeportugal.pt.
ISP blocking mechanism: Portugal uses DNS-level blocking of blacklisted casino domains. A VPN bypasses this effectively. Crypto USDT payments on TRC-20 are network transfers not subject to ISP-level payment blocking — only the domain access (for the web interface) is affected.
Portuguese Gambling Tax: Gambling winnings from SRIJ-licensed operators are exempt from IRS (Imposto sobre o Rendimento das Pessoas Singulares — personal income tax) under Article 12 of Decree-Law 66/2015. Offshore gambling winnings do not benefit from this exemption and may be treated as miscellaneous income subject to IRS at marginal rates.
EUR to USDT — The Deposit Path for Portuguese Players
MB Way: MB Way is Portugal's dominant mobile payment system, operated by SIBS (the Portuguese interbank payment network). Over 6 million registered users. MB Way allows instant EUR transfers between Portuguese bank accounts via mobile phone number. Most major crypto exchanges (Coinbase, Bison Digital Assets) accept MB Way as a payment method in Portugal. MB Way → Coinbase → USDT TRC-20 is the fastest EUR-to-casino path for Portuguese players.
Bison Digital Assets: Bison is a German-origin crypto exchange with Portuguese market coverage. Accepts SEPA and MB Way for EUR deposits. Offers USDT TRC-20. Licensed under EU MiCA framework. A solid option for Portuguese players wanting a regulated EU exchange with MB Way support.
Coinbase Portugal: Coinbase is available in Portugal under its EU regulatory framework (MiCA compliance from Dublin entity). Accepts MB Way and SEPA. Offers USDT (ERC-20 primarily, but USDT can be transferred and converted). Purchase USDT, verify TRC-20 withdrawal support before initiating casino deposit.
SEPA bank transfer → Kraken/Bitstamp: Portuguese bank accounts (Caixa Geral de Depósitos, Millennium BCP, BPI, Montepio) support SEPA EUR transfers. SEPA to Kraken or Bitstamp settles within 1 business day. For larger EUR-to-USDT conversions without MB Way, SEPA to Kraken is the most cost-effective path.
VPN for SRIJ-blocked sites: Use a VPN (NordVPN, ExpressVPN, Mullvad) to bypass Portuguese ISP DNS blocking of SRIJ-blacklisted casino domains. Connect to a Spanish, Swiss, or French server for geographic proximity.
SRIJ-licensed operator winnings — tax exempt: Gambling winnings from SRIJ-licensed operators are exempt from IRS under Article 12 of Decree-Law 66/2015. This covers major licensed online casino operators (PokerStars PT, bet365 PT, Betclic, Solverde Online).
Offshore gambling winnings: Winnings from offshore operators without a SRIJ licence are not covered by the Article 12 exemption. They may be taxable as "other income" (Categoria H or other categories) under IRS. Portugal taxes worldwide income for tax residents. Autoridade Tributária e Aduaneira (Portugal's tax authority) has increased attention on unreported foreign income including crypto-related activity.
Crypto taxation: Portugal introduced a comprehensive crypto asset tax framework. Crypto gains from disposal (selling, exchanging) held for less than 365 days are subject to IRS at 28%. Gains from crypto held more than 365 days are tax-exempt for individuals. USDT (a stablecoin) held for casino play and returned as USDT is unlikely to generate a taxable gain unless the EUR value of USDT changes significantly (USDT maintains EUR/USD parity by design).

Frequently Asked Questions
Can Portuguese players use offshore crypto casinos?
Offshore crypto casinos without a SRIJ licence are prohibited from serving Portuguese players. SRIJ maintains a public blacklist — Portuguese ISPs block these domains at DNS level. Individual Portuguese players using offshore sites are in a grey zone — enforcement has targeted operators, not individual players. A VPN bypasses DNS blocking. Crypto USDT payments are not subject to payment-level blocking by Portuguese banks.
How do Portuguese players deposit at crypto casinos?
MB Way → Coinbase or Bison Digital Assets (EUR to USDT) → casino wallet (USDT TRC-20). MB Way is Portugal's dominant instant mobile payment (6M+ users) and is accepted by Coinbase and Bison in Portugal. Alternatively, SEPA bank transfer to Kraken/Bitstamp. Send USDT TRC-20 to casino (fees: €0.50–€1.00). If casino domain is SRIJ-blacklisted, use a VPN.
Are gambling winnings taxed in Portugal?
Winnings from SRIJ-licensed operators are exempt from IRS (personal income tax) under Article 12 of Decree-Law 66/2015. Offshore casino winnings are not covered by this exemption and may be taxable as other income under IRS at marginal rates. USDT-denominated winnings converted to EUR may additionally be subject to Portugal's crypto asset tax framework (28% on gains from assets held under 365 days; exempt if held over 365 days). Consult a Portuguese tax advisor (TOC) for specific guidance. Not tax advice.
