Funnily enough she got the age credit Joe. I can't fathom it tbh. Between her employer and her accountant (and herself not paying enough attention to her finances) some big mistakes have been made IMO. When I say she paid PRSI, I mean she paid it on her PAYE income, but she has been furnishing her accountant with her P60 so he must have seen it. I'm a layman and it was something I found fairly quickly on the Revenue site.
I called the DSP Refunds Section and gave her PPS and the guy told me she should claim a refund asap as she's already overpaid PRSI to the tune of 3.5k but can only claim app. 3k back (ie, the last 4 tax years @ app. 750 per year.
Ok, I'll stick with the Form 11 and pay prelim tax and the balance for last year. It suits me this way anyway because I want her to register for Income Tax and ROS and then I can submit her returns for her from where I live (in Germany) without hindrance. As you correctly point out, an electronic Form 12 submission is not yet possible.
I've all the workings done anyway, just need to copy the figures over to the Form 11 from the Form 12 but there's only a few entries really.
As an aside: did they not eliminate the PRSI on rental income exemption for PAYE taxpayers in a recent budget?
