According to this email, South African tax agency SARS has confirmed your filing and credited your account with your refund. It asks you to click a link to confirm your deposit.
However, the email is not from SARS and the link does not open any legitimate transaction record.
Instead, the email is a phishing scam designed to steal your personal and financial information. Clicking the link opens a fraudulent website that looks like it belongs to SARS. Once on the fake site, you will be asked to supply your credit card details along with your name and address and other identity-related information. The site will claim that you must provide this information before your supposed tax refund can be processed.
The information you submit on the fake site will be collected by criminals and used to commit credit card fraud and identity theft.
Tax refund phishing scams are very common and target taxpayers in many countries. Be wary of any email or text message that claims that you are eligible for an unexpected refund and should click a link or open an attached file to verify your details.
Legitimate tax agencies will not send you unsolicited emails that make such requests.
SARS has information about identifying and reporting phishing scams on its website.
