Hi, Say I have $1,000 equity from an IP(in an offset account offsetting loan of this IP). Repair expense of $2,000 was taken from equity and personal account ($1000 each). Repair guy gave me one single receipt of $2,000 towards repair. Question 1 : Do I need to ask maintenance vendor to provide me two receipts of $1,000 each so that it is easy to explain to ATO comes tax time? Or ATO will understand and allows mixed receipt? Questions 2: I own a duplex which I am planning to subdivide. Is the interest for subdivision cost tax deductible (provided I use borrowed money)?
