These are common percentages across modern awards (the General Retail and Hospitality awards use similar ones), not a rule. Night shifts, split shifts and minimum engagement periods all change the answer. The Fair Work pay calculator gives the exact rates for your award.
Why a big week looks over-taxed
Payroll works out the tax on each pay as though you earned that amount every week of the year. A week with lots of overtime is treated as a higher annual income, so a larger share is withheld. Your real tax is worked out once, on the whole year, so if the overtime is occasional you will usually get some of it back at tax time. The payslip checker shows the year-end picture.
Common questions
What is time and a half?
150% of your base hourly rate. At $35.00 an hour that is $52.50. Under most awards the first two or three hours of overtime in a day are time and a half, and anything after that is double time (200%).
Do casuals get overtime on top of the casual loading?
Usually yes, but awards differ on how. Many pay casual overtime at 175% then 225% of the base rate, which builds the 25% loading in. Others apply overtime to the base rate only. Check your award.
Why does overtime seem to be taxed so heavily?
It is not taxed at a special rate. Your employer works out the tax on the whole pay as if you earned that much every week, so a big week is withheld at a higher rate. If your overtime is irregular, some of that comes back at tax time.
Is super paid on overtime?
Not under the super guarantee. Super is owed on ordinary time earnings. Penalty rates for ordinary hours (like a Saturday shift in your roster) do count; overtime hours do not.

How this is worked out
- Each line pays hours × base rate × its percentage. For casuals the ordinary hours include the 25% loading, and the typical casual percentages already include it.
- Tax is the ATO's weekly Schedule 1 withholding on the whole week's gross, with the tax-free threshold claimed.
- Super is 12% of ordinary pay plus weekend and public holiday penalty hours, but not overtime.
