Assumes a similar week across the year. A one-off big week has more withheld on payday under the weekly tax table, with the difference squared up in your tax return.

The multipliers come from your award, not the tax law

Time and a half for the first few hours and double time after that is a common pattern, but it is set by your award or enterprise agreement, not by any tax rule. That is why the multipliers in this tool are editable rather than fixed. The Fair Work Ombudsman at fairwork.gov.au is the authority on what your role must be paid; this page, like the rest of our pay calculators, handles the tax side.

Casual loading is a separate thing again and stacks differently under each award. If you are casual, the casual pay calculator starts from the loaded rate. And if you just want to translate an hourly figure into annual pay without overtime, use the hourly rate calculator.

How overtime is taxed in 2026-27

There is no special tax rate for overtime. It is ordinary income taxed through the same 2026-27 tax brackets as the rest of your wages. On $40 an hour with 4 hours of overtime at 1.5x each week, the overtime adds $240 gross and about $163 to weekly take-home, meaning you keep roughly 68% of it at that income.

The reason overtime feels heavily taxed is the withholding mechanics. A one-off big week is annualised by the withholding tables, as if you earned that much every week, so payday tax jumps. The overpayment washes back as a refund when you lodge. To check what a single week should have withheld, put the gross through the weekly tax calculator.

Frequently asked questions

Is overtime taxed at a higher rate?
No. Overtime is ordinary income under the 2026-27 brackets. A single overtime-heavy week has more withheld on payday because the weekly tax table treats it as your normal pay, but the extra comes back at assessment if the year evens out.
What rate should my overtime be paid at?
Whatever your award or enterprise agreement says, commonly 1.5x and then 2x the base rate. There is no universal legal multiplier, which is why this calculator lets you edit them. Check your award on fairwork.gov.au.
Does overtime count towards super?
Generally no. Overtime payments are not ordinary time earnings when your ordinary hours are clearly identified in an award or agreement, so the 12% super guarantee is not payable on them. If ordinary hours cannot be identified, all hours count.
Why did a huge chunk of my overtime week disappear in tax?
PAYG withholding annualises each pay period. One $2,500 week is withheld as if you earn $2,500 every week of the year, which lands in a higher part of the scale. Your actual tax is worked out on annual income when you lodge, and the difference is refunded.
Do casual employees get overtime rates?
Often yes, on top of or interacting with casual loading, but the rules are award-specific. The Fair Work Ombudsman pay tools will tell you what applies to your classification.
Can my employer require overtime?
That is an employment law question rather than a tax one. The National Employment Standards deal with maximum weekly hours and reasonable additional hours; fairwork.gov.au covers where the line sits.
