Budgeting for property tax in Australia
How property tax is typically calculated from an assessed value and a rate, with a monthly budgeting figure for owners in Australia.
Key facts
| Place | Australia |
|---|---|
| Tax | GST |
| Standard rate on file | 10% |
| Multiply net price by | 1.1 |
| Tax share of a gross price | 9.09% |
| Currency | AUD |
Assessed value times rate
Most property taxes start with an assessed or rateable value set by a local authority, multiply it by a rate, and then apply any reliefs or exemptions. The assessed value is not always the market value, so use the figure on your latest notice if you have one.
Worked example
Here is the calculation with sample figures. Change any number in the Australia Property Tax Calculator to run your own.
| Assessed value | A$750,000.00 |
| Tax rate (%) | 1% |
| Annual tax | A$7,500.00 |
|---|---|
| Monthly tax | A$625.00 |
Local differences
Rates are often set locally, so two similar homes in Australia can pay very different amounts. The calculator uses 1% as a placeholder; replace it with the rate from your local authority.
Budget monthly
Dividing the annual bill by 12 gives a monthly amount to set aside, which avoids a large one-off payment catching you out.
Quick reference at 10%
Common amounts in Australia, worked both ways: adding tax to a net price, and extracting it from a price that already includes tax.
