What you can do with this calculator

This calculator is available for the current income year only.

The Income tests calculator will help you work out your:

  • adjusted taxable income (ATI) amount, which is needed in the calculation of some tax offsets – different thresholds may apply depending on the type of offset being claimed
  • rebate income for seniors and pensioners tax offset
  • income for surcharge purposes to determine liability for Medicare levy surcharge.

Your income for these income tests includes some amounts which are not included in assessable income, for example, reportable employer superannuation contributions.

Your income for these income tests excludes the assessable First Home Super Saver (FHSS) released amount. You will receive a payment summary from the ATO showing the assessable FHSS amount and tax withheld.

The results of this calculator are based on the information you provide. You should use these results as an estimate and for guidance purposes only.
