About Workings

Workings makes Australian tax and money calculators that show their working. Where most calculators hand you a number and ask you to trust it, every figure here links back to the government office that set the rate, carries the date it was last checked, and shows you the calculation step by step.

Where our numbers come from

We don't copy rate tables from other calculator sites — a mistake on one site spreads to a dozen others that way. Every rate comes straight from the government office that sets it: Revenue NSW, the State Revenue Office, RevenueWA and the rest. We record the exact page it came from and the date we checked it, both of which are shown on every calculator.

We also check each calculation against a real example the authority publishes, so the figure you get matches what the revenue office itself would work out. If a state changes its rates and our numbers no longer match, we don't show them until they do.

How often we check

State duty rates are reviewed after each state budget, and every rate on the site carries the date it was last checked — shown on the calculator page, not buried. If a rate hasn't been reviewed within thirteen months, the site flags it for us automatically.

Where we can't help

We publish estimates, not advice. A calculator can't know your residency, your visa status, whether you've owned property before, or the conditions attached to a concession — all of which change what you actually pay. For a decision that turns on the number, talk to a conveyancer, a registered tax agent, or the revenue office directly. See our full disclaimer.
