The other day I received a text message supposedly from revenue.ie saying to login to website.

The Revenue Commissioners have become aware of fraudulent mobile phone text messages, purporting to come from Revenue, containing a link to a website seeking personal information in connection with a tax refund.
These text messages did not issue from Revenue.
The Revenue Commissioners never send unsolicited text messages.
Anyone who receives an unsolicited 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.
Anyone who provided credit/debit card information in response to these text messages should contact their bank or credit card company immediately.
