Australian tax calculator for salary and side income

Add your salary, WFH hours, reviewed expense claims and optional sole trader income. See an indicative refund or amount owing without signing in.

Estimate only. Not financial advice.

1. Your job

Enter total gross pay and tax deducted across all jobs for the year.

2. WFH and employee expenses

The 2025–26 fixed rate is 70¢ per recorded WFH hour for eligible running costs. Equipment claims are separate.

Other employee expenses

Enter the amount you expect to claim. If you used an item 50% for work, you may only be able to claim part of its purchase price.

Don’t duplicate costs covered by your WFH claim or reimbursed by your employer.

3. Business / Side hustle (optional)

For sole trader income, enter revenue and eligible expenses. (GST registered? Enter amounts excluding GST.)

Business expenses

Enter this year’s claim for each expense. For assets, this may be less than the full cost.

I meet the ATO requirements for the small business income tax offset (estimate up to $1,000)

If business expenses exceed revenue, the loss is flagged for review and is not used to reduce salary in this estimate.

Sources and scope

Calculator last updated: 24 September 2026. Calculation basis: 2025–26 Australian tax rules.

The estimate uses ATO resident income tax rates, the low income tax offset, the single-person Medicare levy, the 70¢ WFH fixed rate and, only if selected, the small business income tax offset. It is for planning, not lodging.
