The Federal Budget on 9 May 2023 did not result in any changes to tax rates or income thresholds for the 2023-24 income year. The stage 3 legislated tax cuts don’t take effect until the 2024-25 income year. Therefore, there are no changes to Schedule 1 – Statement of formulas for calculating amounts to be withheld (NAT 1004) nor to the regular tax tables. The updates that were made on 13 October 2020 to schedule 1 and the regular tax tables will continue to apply to payments made from 1 July 2023.
However, for the 2023–24 income year we will be updating Schedule 8 – Statement of formulas for calculating study and training support loans components (NAT 3539) and study and training support loans weekly, fortnightly and monthly tax tables due to the annual indexing of the repayment income thresholds. The NAT 3539 output file that will apply from 1 July 2023 is provided under 'Resource Attachments'.
The updated schedule 8 and associated tax tables will be published from mid-June at ato.gov.au/tax tables
Other important information
We do not update the statement of formulas and regular tax tables to only accommodate the annual indexation of the Medicare levy thresholds. We only factor in the Medicare levy changes when we have to make changes to the tax tables due to changes to tax rates and/or income thresholds. We don’t consider making changes to tax tables just for Medicare levy thresholds economical for employers, digital service providers and the ATO, as their effect on withholding is minimal. When individuals lodge their income tax return for the year, the up-to-date Medicare levy thresholds will apply.
