    Online: false websites and phishing

    Attempts at deceipt make reference to supposed tax refunds through mass e-mailings which misappropriate either the identity and image of the Tax Agency or the identities of its directors. Fraud attempts often refer to alleged information that prevents the tax refund payment from being sent while supplanting the image of the Tax Agency.

    These fraudulent mailings, known as “phishing”, refer to a non-existent tax refund benefiting the receiver of the e-mail. In order to receive the money, the taxpayer has to access an address website or complete a form providing details of their bank accounts and credit cards.

    The Tax Agency reminds users that the best measure is precaution in response to any suspicious communications which include requests for bank details.

    • it never requests by e-mail from the taxpayers any confidential, economic or personal information or numbers of accounts or cards.
    • It never makes refund paments on credit cards;
    • It does not charge for the services that it provides. The user will only assume the shared cost of calls to 901 telephone numbers.

    Text messages (SMS) not sent by the Tax Agency

    Tips for the prevention of Internet-based fraud

    Fraud attempts may take the form of mass emails purporting to come from the Tax Agency and imitating its image.

    These emails usually offer a tax refund which does not actually exist. In order to receive the money, the recipient has to go to a website where they are asked to give their bank account and credit card details. Do not click on any links or attached files that come from a suspicious email.

    The Tax Agency never emails taxpayers to ask for confidential financial or personal information, or bank account or credit card details.

    For maximum security, always type the address of the Tax Agency website into the browser, rather than clicking on a link.

    And especially, before logging into the e-Office, check the site security certificate.
