Wondering if this is a good strategy: - Loan of 300k - 100% offset account - Interest rate around 6.5% Dad sold his property and has spare cash which he has put his money into an account that gives him a return of around 6%.. obviously he pays tax on the returns too. So.. instead, what if Dad gave me 300k to put into my offset account. Obviously the bank would be making no money in interest. But that 300k is now 'tax free'. And instead of me paying the bank back.. I can now just give Dad an agreed interest rate return on his money invested in my offset account. Is this a good strategy? Would Dad still get taxed on my 'donations' back to him for 'lending' me the money in my offset?
