Quick Tax Calc

This is a quick calculator for the ATO Australian tax witholding formula

It's based on Scale 2 - claiming the tax free threshold, no Medicare levy exemption.

How to use

Type your annual pre-tax amount in the income section and see your after tax annual and fortnightly amounts.

You can use the memory button (M) to remember a given fortnightly amount for comparison.

The income section also allows for formulae so you can do things like:

  • How might a 10% raise affect my income?
  • What if I get an extra job paying 500 a week?
  • If I go 3 days a week, how much will I get paid?
  • What contractor daily rate is comparable with my full time salary?
