About PAYG Calculator Australia

What this site does

PAYG Calculator Australia does one job: it shows how much tax comes out of Australian pay, and what lands in the bank. The calculators cover PAYG withholding, take-home pay, PAYG instalments and the 2026-27 tax tables for weekly, fortnightly and monthly pay. The guides explain the system behind the numbers: how withholding works, what an income statement shows, when the ATO puts you on instalments, and how HELP repayments come out of your pay.

Everything on the site is free to use. Every rate and threshold quoted is for the 2026-27 financial year and traces back to a published ATO source.

What this site is not

• It is not tax advice. The figures are general estimates based on the details you enter. They do not account for your deductions, offsets beyond the low income tax offset, or anything else specific to your return. For advice on your own situation, see a registered tax agent.
• It is not the ATO. This site is independent. It is not affiliated with, endorsed by or connected to the Australian Taxation Office or the Australian Government in any way.
• It is not selling anything. There are no accounts, no lead-generation forms, no paid services and no advertising. Nobody will call you, and your salary figures never leave your browser.

How the figures are produced

Every number on the site comes from a single tax engine that implements the 2026-27 rates the ATO has published: the resident, non-resident and working holiday maker tax scales, the Medicare levy with its low-income phase-in, the low income tax offset, HELP marginal repayments and the 12% super guarantee. The tax tables are generated from that engine, not typed in by hand, so a rate can only ever exist in one place.

Per-pay figures are annualised approximations of the ATO's per-pay-event schedules, so a payslip can differ by a few dollars each pay. The full detail, including sources and known limitations, is on the methodology page.

Who writes the content

The guides and explanations are written by Narelle Hartigan, CPA, a tax accountant with over a decade of experience in Australian personal taxation and payroll. She checks every rate on the site against the ATO's published figures.
