Landlords can already deduct the interest on mortgages used to purchase their rental property. They can deduct, as Ms Costello said, insurance costs, maintenance costs, repair costs and RTB registration fees. When we compare that with workers who have mortgages, they cannot deduct from taxes they pay for their labour mortgage costs, interest rate costs, the cost of insurance or the cost of maintenance. Therefore, the passive income earned by landlords is already taxed less than income earned through work. What is the effective tax rate on rental income after those deductions are made?
