What happens when your assessment increases?
When your local assessor raises the assessed value of your property — whether due to market conditions, renovations, or a periodic reassessment — your property tax bill will typically increase. At a 0.366% effective rate in Australia, a $50,000 increase in assessed value would add approximately $183 to your annual tax bill, or about $15 per month.
