Hi, Many IT contractors in my circle advise working as ABN contractor can save lots of tax. However they can't explain how as their tax affairs managed by accountants. Here is our situation: Spouse 1: Contract rate: $960 per day inc super - PAYG ($219k yearly taxable working 250 days a year) Spouse 2: Contract rate: $850 per day inc super - PAYG ($194k yearly taxable working 250 days a year) Considering: - Contract rates (salaries) remain same. - Tax affairs managed by accountant hence incurring accountant fee. - Own one car - drive to work together (same work location) - 2 kids. One 8 yo another 2yo. - Own 6 investment properties averaged neutral geared. question: Would we have more after tax money in our bank account at the end of year if we move from PAYG to ABN (or Pty Ltd. Not sure if it is the same thing) ?
