Thanks Domo.
In '05, i was in UK for first 7 months, 1 month back in Ireland and then 94 days in US. While in UK, I was working in UK company and paying tax there. All time spent in US I was working for Irish compnay and PAYE in Irish system.
In '06, I spent 160+ days in US before returning home. Not sure if i'm entitled to anything? I rang tax office about this and they told me they didn't know (!) but that I should send in a letter with my details.
Preparing a letter with details at the moment.
Any thoughts?
