Portugal’s Tax and Customs Authority has issued a public warning after identifying a rise in fraudulent emails and text messages circulating in its name. The scam attempts are designed to mislead taxpayers imitating official communication and prompting recipients to take urgent action. Authorities say the messages often claim there are pending tax issues or refunds available, encouraging users to click on links or provide personal information. Officials have stressed that these communications are not legitimate and are part of a broader wave of digital fraud targeting individuals during sensitive financial periods.
According to the authority, several examples of these messages have already been reported taxpayers, raising concerns about the scale of the activity. The emails typically include subject lines related to tax regularisation or provisional deductions, creating a sense of urgency to prompt quick responses. In many cases, the sender names appear similar to official tax departments, but the email addresses themselves are clearly unrelated to government domains. These tactics are commonly used to gain trust and trick recipients into revealing confidential data such as login credentials or banking information.
Officials have advised taxpayers to remain cautious and to avoid clicking on any suspicious links or downloading attachments from unknown sources. The authority emphasized that it does not request sensitive personal or financial information through unsolicited emails or SMS messages. Any communication that appears to demand immediate action or threatens penalties should be treated with caution. Instead, individuals are encouraged to access official services directly through the government’s online portal to verify any claims regarding their tax status.
Cybersecurity experts note that phishing attempts tend to increase during periods when individuals are expecting tax related communication, making it easier for fraudsters to exploit uncertainty. The use of realistic language and official sounding references can make these messages difficult to identify at first glance. However, inconsistencies such as unusual email domains, spelling errors or generic greetings often serve as warning signs. Public awareness remains a key defence against these types of scams, especially as digital communication becomes more central to government services.
The tax authority has indicated that it will continue monitoring the situation and encourages anyone who receives suspicious messages to report them through official channels. tracking these incidents, authorities aim to limit the spread of fraudulent campaigns and protect taxpayers from potential financial harm. The warning forms part of ongoing efforts to strengthen digital security and maintain trust in public institutions as online interactions between citizens and government agencies continue to grow.
