The most valuable thing you can send is a correction. If a figure on this site does not match the ATO or Fair Work, I want to know — email silvanopara@gmail.com and the fix gets logged publicly with the date.

This reaches Silvano Para, who builds and maintains the site. It's a one-person project, so replies aren't instant — but corrections to a published figure are treated as urgent and fixed the same day they're confirmed.
What to send
- A correction. Include the page URL, the figure you think is wrong, what it should be, and the ATO or Fair Work page you're working from. See corrections for how these are handled and logged.
- A methodology question. If something in the method is unclear or you think an assumption is wrong, that's useful — assumptions are where calculators quietly diverge.
- A privacy enquiry. See privacy first; we hold no calculator data, so there is usually nothing to access or delete.
What I can't help with
I can't advise on your personal tax position, tell you what to claim, review your return, or intervene in a dispute with an employer. Those need:
- Your tax — a registered tax agent, or the ATO directly.
- Pay, awards, redundancy entitlements or a workplace dispute — the Fair Work Ombudsman.
- General money guidance — the government's MoneySmart.
Media and data requests
The methodology and all underlying rates are published openly on the methodology page and may be cited with attribution. If you need the figures in a machine-readable form, see /llms.txt.
