It's important to be aware of this scam.

Revenue recently issued a warning following reports of a scam in which emails, texts and calls which appear to be from the Revenue Commissioners ask for personal information and seek credit card details.

''These emails and text messages did not issue from Revenue. The Revenue Commissioners never send emails or text messages requiring customers to send personal information via email, text or pop-up windows. Anyone who receives an email or text message purporting to be from Revenue and suspects it to be fraudulent or a scam should simply delete it. Anyone who is actually awaiting a tax refund should contact their local Revenue Office to check its status.'' The Revenue Commissioners said. ''Anyone who provided personal information in response to these fraudulent emails or text messages should contact their bank or credit card company immediately.'' They added.

Gardaí issued a similar warning about the scam.

 ''This is a scam and An Garda Síochána would like to remind the public to be wary of any contact from an unsolicited source, whether it is by telephone or email." It reads. "Do not give out your credit/debit card, bank account, or PPS number to anyone who makes contact with you over the phone. An Garda Siochana, Revenue, nor any financial institution will ever call you and ask for your PPS number or bank account details." It adds.

If you do receive a call from one of these scammers, you're advised to ring the Garda Confidential line on 1800-666-111. For more information you can visit Revenue's security section on their website.
