Sunday Accounting provides accounting and payroll software for Australian small businesses.

Alongside our software, we publish plain-English explanations of Australian payroll, superannuation and small business compliance to help business owners understand what is required of them and why.

This site exists to explain how the rules work in practice, based on current legislation and guidance from the Australian Government.

Sunday Accounting focuses on a narrow set of topics relevant to Australian small business owners, including:

• Payroll obligations

• Superannuation, including Payday Super

• Single Touch Payroll (STP)

• BAS and related small business compliance requirements

We deliberately do not try to cover everything. Our goal is clarity, not breadth.

All content published on this site is written in plain English and reviewed against current legislation and Australian Taxation Office (ATO) guidance.

Where possible, we distinguish clearly between:

• what the law requires

• what government guidance says

• what this means in practical terms for small businesses

Content is reviewed regularly and updated when rules or guidance change.

This site does not provide personal tax, legal, or financial advice.

The explanations here are general in nature and are intended to help business owners understand their obligations, not replace advice from a qualified professional who understands their specific circumstances.

We also do not cover non-Australian payroll or tax systems.

Sunday Accounting provides accounting and payroll software for Australian small businesses.

The explanations published on this site are intended to stand on their own, regardless of what software a business uses. When software is mentioned, it is to illustrate how a requirement may be handled in practice, not to replace an explanation of the underlying rule.

This site is actively maintained.

Each page includes a review date so readers can see when the information was last checked against current legislation and ATO guidance.
