A few months there was a scam going around purporting to come from Revenue offering you a refund of income tax and it was a good attempt to scam people but of course seeking personal information. This time of year is always busy with the scam front and I have been subject to an ongoing issue with PayPal myself which they are still trying to sort out.
Again this email is similar and here is what you need to look out for and it will ask you to open a link and fill in information but by all means DO NOT open any link in the email and just discard it straight away you can see the information provided in the link as what you need to watch out for so you have been warned and it is another phishing attempt.
Revenue do have an advice section on their website if you need or feel you have got a suspicious link HERE
