Tax withheld calculator

What is the Tax withheld calculator (TWC)?

If you are an employer or another withholding payer, the TWC helps you work out the tax you need to withhold from payments you make to employees and other workers.

To use the TWC, you need the information your workers supply in their:

• Tax file number declaration (NAT 3092)
• Withholding declaration (NAT 3093)
• Medicare levy variation declaration (NAT 0929).

The TWC takes into account the:

• income tax rates
• Medicare levy
• Student Financial Supplement Scheme (SFSS) contributions
• Higher Education Loan Programme (HELP) contributions
• worker's residency status
• tax-free threshold
• tax offset entitlements.

From 1 July 2012, the temporary flood and cyclone reconstruction levy (flood levy) no longer applies.

Current version

The online version of the Tax withheld calculator (TWC) is effective from 1 July 2012 and applies to payments made in the 2012-13 income year.

From 1 July 2012 the downloadable version of TWC is no longer available.
