Not only does paying less tax obviously mean more money stays in your pocket than goes to the government, but it can also feed into how your financial strategy to build your wealth and every 12 months can continue to help execute on that plan. The large the amount of tax deductions, the larger your return, the more of that money you can put back into your existing home loan (which is going to be an owner occupied residency with significantly less tax advantage), the more the extra money will reduce the interest you'll pay over the life of the loan. Tax can and should become a consistent part of your wealth building strategy.
