I am currently in the market to purchase a principal place of residence. My dad has some money saved that is currently held by a company of which he is a shareholder/director. Dad and I have discussed me borrowing a sum of money from him to use towards a house deposit.
I am wondering (a) what is the tax treatment for my Dad's company if it loans me the money? (b) does the loan have to be made at a set interest rate or can we agree on an interest rate between the two of us (eg a rate approxiately the same as bank loans are being offered)? (c) how does the loan get treated for my personal income tax purposes?
