I received an email from a colleague that he received stating that PRSI refunds were available and the text stated is below. Anyone know if this is actually the case? Also, any possibility that it could result in finding out that on ehad under paid?! Thanks S MG '... everyone who was working in ROI in the past 4 years can claim PRSI refund(not tax!). PRSI was counted incorrectly due to some error in the calculator in years 2007-2010. It's not being advertised but it's being incorrectly calculated for everyone!! The only thing you need to do is to write simple letter with an application for your refund to below address(include PPS number): PRSI Refunds Section, Department of Social Protection, Oisin House, 212-213 Pearse Street, Dublin 2.'
