Get in touch

G'day! Dinkum Calc is kept going by one person checking rates against the ATO and the state revenue offices. If something looks off, a rule has changed or you've got an idea for a tool, we'd love to hear from you.

Contact details are coming soon.

What you can write about

• Report a wrong figure

  Tell us which page, what you entered and what you expected. A link from a calculator's Copy link button (or its "Spot a wrong figure? Tell us" link) fills your inputs back in for us.

• A rate or rule has changed

  A new tax rate, threshold, duty bracket or concession? A link to the official source (the ATO, Treasury or a state revenue office) helps us update it quickly.

• Idea for a new tool

  A money question you can't find a calculator for? Tell us what it would work out and who it would help.

• Something else

  Feedback, a broken link or anything that doesn't fit above.

Or write to us directly:

How it works

• There's no form. Nothing is sent from this site. Each button opens your own email app with a subject and a few prompts filled in, and you choose what to send.
• Wrong-figure emails carry your inputs. The link in them includes the figures you entered so we can see the same result. Delete anything you'd rather not share before you send.
• We read every message, but we can't promise when, or that we'll reply to each one.
• We can't give personal financial advice. We can't tell you what to do with your money or check your own tax position. For that, talk to the ATO, a registered tax agent or a licensed financial adviser.

See the privacy policy for how your information is handled and the terms of use for how the calculators may be used.
