A few seconds after clicking on a link received via SMS, a phone displayed a form requesting banking details under the pretext of regularizing a property tax reminder. The message included the recipient's address, a plausible amount, and an administrative tone. However, the French tax authority DGFiP does not notify property tax notices via SMS, and no such messages or links exist in its official procedures. A recent hacking of DGFiP systems allowed the extraction of tax and cadastral data, which fraudsters used to make the messages more credible. These scams involve impersonating an administration's identity, a punishable offense by one year in prison and a 15,000 euro fine. The SMS messages often contain real information about victims, such as tax identification numbers, property addresses, or tax references, making them more convincing. Clicking on the link typically redirects the victim to a fake tax office page that closely resembles the official site, with differences such as a slightly modified web address or an immediate payment request that is not typical for tax office interactions. These small discrepancies are often overlooked by users, who may be tricked into entering their personal and financial information. The DGFiP only communicates through its official website, impots.gouv.fr, accessible after secure identification. Official email addresses always end with @dgfip.finances.gouv.fr, and the real tax office pages use exclusively the .gouv.fr domain. Any variation in these details should raise suspicion. The link in the fraudulent SMS did not lead to information consultation but directly to a payment form, which is not standard for official tax notices. The official payment of property tax should occur later in the tax calendar, with online payments due by October 20 and other methods by October 15. To avoid falling victim, individuals should remember that the DGFiP never asks for credit card numbers via SMS, email, or telephone. They should check the website address before entering any information, log in only via the official private space on impots.gouv.fr, and never transmit banking details in response to unsolicited messages. Fraudulent messages should be reported to the competent authorities to help prevent others from being scammed.
