  • 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.
