My wife recently stopped working and i took her remaining credits for last year which was my entitlement. I assume her credit will remain with me for the forthcoming year. She then started consultancy from this company and they pay her monthly(cheque). Sh ahs yet to set up a company(or sole trader) but that is another matter. The yearly figure for this consultancy will be below the figure with which you have to start paying taxes(€15,500..???). My question is, do i have to take my credit back off me and back to the wife as if not, could she be hit with a 41% tax on her income..
