Revenue has issued a further warning to taxpayers to be vigilant of individuals claiming to be Revenue officials and seeking personal information (e.g. PPSN numbers or addresses, details of earnings) and/or demanding payment of tax. Readers are advised that, if they receive a telephone call purporting to be from Revenue, or receive an email or other contact demanding payment, of about which they have doubts, they should contact their local Revenue Office or Revenue's Collector General's Division.
