Editorial policy

Responsibility for our calculations and content

Clear sources, visible limitations and a practical way to report errors.

Policy updated 14 September 2026

Who is responsible

Payko is published by Synthetik, a registered business name of Cenex Pty Ltd. The publisher is responsible for calculator content and corrections. Publisher and contact details.

No individual tax professional is named as a reviewer for this release. Automated calculation checks are software verification; they are not a professional tax review. We will only identify a reviewer and their qualifications when a specific review has actually been completed.

Sources and dates

Tax rates and thresholds should be traced to legislation or the relevant Australian government authority. Each release's source register distinguishes confirmed inputs from carried-forward assumptions. Source-check dates and test-run dates are recorded separately.

Writing and automation

Calculators and salary examples can be generated from shared software. Software and AI-assisted drafting may be used to prepare updates. A generated example does not establish professional review. Published test claims must link to the checks actually run and describe their scope.

Review priorities

Rate reviews should focus on the July financial-year change, new legislation, ATO schedule updates and reported discrepancies. A scheduled review intention does not mean a review has happened; the dated source register is the record of completed checks.

Commercial independence

Calculator results should follow the documented inputs and rules. Sponsored material and advertising must be clearly labelled and kept separate from results. An external link must not be presented as a government or professional endorsement.

Corrections

Report a suspected error to hello@payko.com.au. Include the page, year, nonsensitive example inputs, expected result and supporting source. Confirmed calculation changes should be dated on the corrections page, with their impact and verification. Please do not send personal tax documents, a TFN or bank details.
