I'm doing my first Form 12 return having rented out my old house for the first time in 2008.
Due to a combination of ignorance and laziness, I continued to receive Mortgage Interest Relief on this property long after it ceased to be my PPR. I eventually rang Revenue to tell them about it. I innocently expected to receive a bill from Revenue for the repayment of this relief but it never came.
Now in my Form 12 I want to use the full interest that I should have been paying as a deduction on my rental income tax. But what's the best way to do this? Should I take the interest I paid in 2008 and just subtract the relief that I already received on it?
(That wasn't as easy to explain as I thought .....)
Thanks.
