General information only

The content and calculators on Duty & Pay are general information. They are not financial advice, tax advice, legal advice or credit assistance, and they do not take account of your objectives, financial situation or needs.

Estimates, not assessments

Every figure produced here is an estimate based on published rates. Only the relevant state revenue office or the Australian Taxation Office can tell you what you actually owe. Concessions and exemptions have detailed eligibility rules that a calculator cannot assess.

Accuracy

We take care to keep rates current and to source them from official pages. Even so, rules change, announcements are made mid-year, and errors are possible. Do not rely on this site as your only source when money is at stake.

Assumptions used

• Tax calculations assume you are an Australian resident for tax purposes and claim the tax-free threshold.
• They do not include the Medicare levy surcharge, deductions, other income, or salary packaging.
• Stamp duty calculations assume a standard residential purchase. They do not include off-the-plan concessions, pensioner concessions, or duty on business assets.
• First home buyer concession amounts between thresholds are estimated on a straight-line basis. Some states use their own formula, so the exact figure can differ.
• Registration fee figures are approximate and differ by state.

External links

Links to revenue offices and other sites are provided for convenience. We do not control that content and are not responsible for it.

Liability

To the extent permitted by law, we accept no liability for any loss arising from the use of this site. If you are making a financial decision, speak to a registered tax agent, a licensed financial adviser, or a conveyancer.
