I'm thinking of setting up a homebased business which initally will not be making much profit (starting small). I'm trying to find out how this will effect our joint tax situation. I am currently PAYE but will fininsh work soon. If I go ahead with the business idea and register for tax as a sole trader - how does this effect our credits etc and also if I am not generating much (if any profit) for the first few years will I have to pay PRSI from money I am not earning? Sorry if this sounds a stupid question but have surfed around and can't find the answer.
