2026 Federal Budget CGT rules

Your property's CGT record.
Certified. Defensible.

The 2026 Budget split capital gains into two periods and changed the rules on negative gearing and the 50% discount. CostBase assembles your cost base, models your CGT, and has a registered valuer certify the result.
