Hi
We were able to have deductions such as - interest paid on the mortgage, insurance, maintenance costs, travel (flight to Ireland), phone calls.. We had the property rented so could show the rental income for this . I think there are different forms that need to be completed if the business is loss making, so you should check with an advisor (maybe someone in HR block) I think it may mean that you're more prone to being audited but I'm not sure.
I think when we move home I'll make contact with a tax advisor to sort it all out. The first year I worked with someone in Ireland but I haven't dealt with them since and haven't done any returns in Ireland since then as I didn't think I needed to..
And yes - I am the worrying kind .. I want to make sure that everything is absolutely right.. I'm sure there's a few things I've overlooked but seeing as I'll be back in Ireland in a few months it will be easier to sort out then I think.
Thanks for the feedback.
