The short answer

If your teacher back pay is missing or looks wrong, first check it's actually due yet, then calculate it: (new annual rate − old annual rate) ÷ 365 × days covered, × your FTE. If the gap is more than a few dollars, email payroll with your working and the payslip. If it isn't fixed within a pay or two, ask your union.

Victorian VGSA 2026 was approved on 16 October 2026 and started on 23 October; back pay then needs payroll processing time.
Queensland's 4.75% award rise was due in the fortnight ending 18 October 2026, back-dated to 1 September.
The most common errors: a step change in the back pay period, part-time FTE and missed allowances.
Super should be paid on back pay of ordinary salary.

Is your back pay actually due yet?

Before chasing payroll, check where your agreement is up to. Back pay can't be paid until the new rates are legally in force, and payroll then needs time to process thousands of records. Here's the position on 20 October 2026.

How to calculate what you're owed

Back pay is the difference between what you were paid and what you should have been paid, for each day in the back pay period. The simplest reliable method uses daily rates.

Back pay in five steps

1

Find the rate change dates

From your agreement or decision. VGSA 2026 has two: the first pay period on or after 10 August and on or after 1 October 2026.
2

Find your old and new annual rates

For your step in each period. If you moved up a step during the period, split it at your increment date.
3

Work out the daily difference

(New annual − old annual) ÷ 365.
4

Multiply by days and FTE

Daily difference × days in the period × your FTE. Add each period together.
5

Add allowances and lump sums

Allowances that rise with salary should be back-paid too. Add any one-off payment, pro rata if you're part-time.

Worked example

Victorian teacher at 2-1, illustrative VGSA 2026 back pay to 30 November 2026

10 Aug to 30 Sep: ($97,274 − $94,415) ÷ 365 × 52 days: About $407
1 Oct to 30 Nov: ($106,758 − $94,415) ÷ 365 × 61 days: About $2,063
Back pay, full-time: About $2,470
Lump sum, full-time: $2,000
Total, full-time: About $4,470
Total at 0.6 FTE (back pay and lump sum × 0.6): About $2,682

Tax At your marginal rate: 32c in the dollar including Medicare for most teachers, plus HELP if you have a debt

Assumes payroll applies the new rate by 1 December 2026; the Department has not published the date. Real pay period boundaries will shift the totals slightly. Rates: VGSA 2022 and VGSA 2026 Schedule 1.

Why teacher back pay comes out wrong

Common back pay errors and how to spot them

Problem	What it looks like	What to check
Step change during the period	Back pay calculated on your old step for the whole period	Your increment date; split the period there
Part-time FTE	Back pay at full-time, or at your current FTE rather than the FTE at the time	Your FTE for each part of the period
Allowances left out	Salary back-paid, allowances not	Allowances that are a percentage of salary or rose with the agreement
Leave without pay	Back pay paid for days you weren't paid	Your leave records for the period
Higher duties	Back pay at your substantive rate only	Higher duties allowance for any acting period
Lump sum	Missing, or not pro rata correctly	Your FTE on the date the agreement measures
Super	No super contribution on the back pay	Your fund a week or two after payday
Split payments	Part of the back pay in one pay, the rest later	Whether payroll has said it's paying in stages

Victorian casual relief teachers should note that they're paid under Ministerial Order 1389, not the VGSA, so VGSA 2026 doesn't automatically change their rate or bring back pay. Queensland supply teachers did get the 4.75% award rise.

How to raise it with payroll

Most back pay errors are fixed quickly once payroll can see exactly what you think is wrong. A clear email with your working gets a better answer than "my back pay looks low".

What to put in your email

Your name, school and employee number (not your TFN or bank details)
The payslip date and the back pay line you're querying
Your step and FTE for each part of the back pay period
The rate change dates and rates you used, with the source
Your calculation and the difference you think is owed
A request for their calculation in writing if they disagree

Where to send back pay queries

State	First contact	Then
NSW	School administration manager, then the Department's payroll service via SAP ESS and staff support	NSW Teachers Federation
VIC	School business manager (they enter eduPay changes)	AEU Victorian Branch
QLD	School business services manager, then Payroll Services	Queensland Teachers' Union
WA	School manager corporate services, then Department payroll	SSTUWA
Catholic and independent	Your school or diocese payroll	IEU branch for your state

Timelines and when to escalate

Give payroll a reasonable chance. A large back pay round, like VGSA 2026, can take more than one pay to process, and corrections usually appear in a later fortnight. If you've had no reply or no fix after two pay cycles, escalate.

Follow up in writing with the original email attached and ask for a date for the correction.
Contact your union. Unions can raise individual and group underpayments directly with the Department, and they often know whether a whole group of teachers was missed.
Outside help. Teachers employed by national system employers (Victorian, ACT and NT government schools and most Catholic and independent schools) can contact the Fair Work Ombudsman about underpayments. Government teachers in NSW, Queensland, WA, SA and Tasmania are in their state industrial relations system, so the union and the state industrial commission are the usual route.

Tax and super on back pay

Back pay is taxed as ordinary income in the year you receive it, at your marginal rate. Withholding on the payslip can look high, but it's settled at tax time. If part relates to an earlier income year, you may qualify for the lump sum in arrears tax offset. Our guide to tax on teacher back pay has the details and a worked VGSA example.

Super should be paid on back pay of ordinary salary, at 12% in most states and 12.75% for Queensland state school teachers. Under Payday Super, it should be paid with the payday the back pay arrives on. If it hasn't reached your fund within a couple of weeks, ask payroll.

Frequently asked questions

When will Victorian teachers get VGSA 2026 back pay?

Once payroll processes it, which may take more than one pay. The Fair Work Commission approved the agreement on 16 October 2026 and it started on 23 October 2026, but the Department has not published the payroll date.

When is the Queensland teacher back pay being paid?

The QTU said the 4.75% award rise would be processed in the fortnight ending 18 October 2026 with back pay to 1 September. The 3% interim rise for Coach, HAT, Lead Teacher and leaders was paid in the fortnight ending 4 October.

How do I calculate my teacher back pay?

Take the difference between the new and old annual rates for your step, divide by 365, multiply by the days covered and your FTE, then add any allowances and lump sum. Split the period if you changed step.

What if my back pay is less than I expected?

Check whether it was paid in stages, then whether payroll used the right step, FTE and dates. If there's still a gap, email payroll with your calculation and ask for theirs in writing.

Do part-time teachers get full back pay?

Part-time teachers get back pay pro rata to their FTE for each part of the period, and lump sums such as the VGSA's $2,000 are also pro rata.

Do I get back pay if I've left teaching?

It depends on the agreement's eligibility clause. Some only back-pay staff employed on a certain date, as WA's 2023 agreement did. Ask payroll and check the clause.

Is super paid on teacher back pay?

Yes, on back pay of ordinary salary. Whether one-off lump sums attract super depends on how the agreement classifies them.

Who can help if payroll won't fix my back pay?

Your union first. Teachers with national system employers can also contact the Fair Work Ombudsman; state system government teachers usually go through the union and their state industrial commission.
