Employers will be required to lower the amount of tax withheld for affected taxpayers to factor in the new lower tax rate effective from 1 October. Any tax overpaid beforehand will be refunded by the ATO on assessment after the end of the 2016/17 financial year. This means that all affected taxpayers will be able to obtain the benefit of the cut within one month of new PAYG withholding tax schedules being published.
In the meantime, the ATO has made the Taxation Administration Act Withholding Schedules October 2016 (F2016L01380, registered on 2 September 2016) to give effect to the new arrangements from 1 October 2016. The instrument contains eight new withholding schedules.
