Portuguese citizens targeted as tax authority scam season opens

If you receive messages of this type, confirm the legitimacy directly with your Tax Authority. If this is not the case, delete them without opening them.

Tax season has begun, and the story repeats itself every year: the hunt for scams begins, with new techniques challenging even the most astute of taxpayers.

The new year had barely begun when the tax authorities in Portugal issued warnings about a fraudulent email inviting taxpayers to visit a certain link to receive their IRS refund. In this case, the attempted scam is fairly obvious, especially since it occurs in January – the Tax Authority never refunds taxes before the income tax returns are filed, which only begins in April. And even if this fact isn't enough to raise suspicions, a closer look helps to expose the fraud - the email address from which the email was sent did not end in ".pt", the domain associated with Portugal, but in ".in", registered in India...

In April 2023, for example, an email that circulated all over the country suggested taxpayers to change "access credentials to the Finance portal". Although this would be perfectly plausible at that time of year, it was, in fact, a scam. In August, another email message warned about "discrepancies" in the IRS declaration and urged correction through the sent link. And, three months later, other emails about supposed tax debts of the recipients appeared, which may have led to some clicks on the pages of cybercriminals.

If you receive such messages, confirm with the Tax Authority of your country if they are legitimate. If not, delete them without opening. In these phishing scams - which allow scammers to access your data - just one click is enough to give them access to everything you own.

Did you know?

In one of the fraud attempts, the address through which the email was sent did not end in ".pt", a domain associated with Portugal, but in ".in", registered in India.

Romance scams continue to grow worldwide, exploiting trust, emotional vulnerability, and online relationships to manipulate victims into financial and emotional harm. Timed around Brazil’s Valentine’s Day period, the latest GASA meet-up, Golpes do Amor — Como eles acontecem e como se proteger, explored how these scams operate, why they are so effective, and how individuals can better recognise warning signs before becoming victims.  Hosted by the Brazil Chapter of the Global Anti-Scam Alliance (GASA), the discussion highlighted findings from O Estado dos Golpes no Brasil. According to the report, romance scams have already affected 18 per cent of surveyed Brazilian adults, while 6 per cent of victims reported falling for this type of scam more than once. Beyond financial losses, speakers emphasised the severe emotional consequences victims often experience, including shame, trauma, and loss of trust.  Read the Report – O Estado dos Golpes no Brasil  Speakers: Rose Leonel, Journalist and Founder – ONG Marias da Internet Tanila Savoy, Founder – Associação Nacional de Vítimas da Internet (ANVINT) Lisandréa Salvariego Colabuono, Police Chief and Coordinator – NOAD, Polícia Civil de São Paulo Renata Salvini, Brazil Chapter Director – Global Anti-Scam Alliance  A major focus of the discussion was the manipulation techniques commonly used in romance scams. Speakers explained how scammers frequently create convincing identities, often pretending to be foreigners, military personnel, or individuals living abroad, while avoiding in-person meetings and building emotional dependency over time. Urgency and financial pressure were highlighted as major warning signs, particularly when victims are pushed to act quickly or send money under emotional circumstances.  The webinar also explored the lasting psychological impact of these crimes and reinforced that victims should never be blamed. Rose Leonel shared her personal story of transforming trauma into advocacy after becoming a victim of non-consensual intimate image sharing, an experience that ultimately contributed to the creation of the Rose Leonel Law in Brazil. Speakers stressed the importance of reporting scams, noting that even small details can assist investigations and help prevent future victims.  The conversation reinforced the need for greater public awareness, victim support, and collaboration between civil society, law enforcement, and digital platforms to address emotionally manipulative fraud more effectively. Through initiatives like this meet-up, GASA continues working with experts and organisations worldwide to strengthen scam prevention and support victims of online fraud.  Watch the full discussion below to learn how individuals and organisations can better recognise and respond to romance scams.
