NSW vs VIC vs QLD payroll tax: a state-by-state comparison

NSW, VIC and QLD all charge payroll tax on wages above a threshold — but the mechanics behind that simple idea are genuinely different in each state. Assuming one state’s formula applies to another is one of the more common ways businesses miscalculate a cross-border estimate. This post walks through each state’s mechanics individually, with worked figures computed by the same calculation logic that powers this site’s calculators.

The headline figures, 2026-27

See the About page for how each figure is sourced and how often it’s re-verified.

NSW: a flat threshold, worked

NSW is the simplest of the three mechanically. There’s one threshold and one rate. Take a NSW-only business paying $1,500,000 in wages for the full year: the threshold available is the full $1,200,000 (no apportionment needed with only one state in the picture), taxable wages come to $300,000, and the estimated annual liability is $16,350 — an effective rate of 1.09% on total wages paid, noticeably lower than the headline 5.45% rate because the threshold shields the first $1,200,000. The complexity only appears once you add a second state or a grouped entity — see our interstate threshold guide.

VIC: a threshold that phases out for larger employers, worked

VIC uses the same idea for small and mid-sized employers, but its threshold isn’t fixed forever — it phases out once total Australian wages climb into the tens of millions, reducing the tax-free amount available to very large employers. Take a VIC-only business with $4,000,000 in wages for the full year — inside VIC’s phase-out band. Instead of the full $1,000,000 threshold, this business gets only $500,000, because the threshold is being wound back at a 50% rate for every dollar of wages above the phase-out start point. That leaves $3,500,000 taxable and an estimated annual liability of $169,750. For the businesses this site is built for — the SMB and mid-market range — the phase-out rarely bites; it’s the apportionment-by-wage-share mechanic that matters most day to day. It only becomes relevant once total Australian wages start approaching the phase-out start point noted in our VIC calculator page.

QLD: a deduction, not a threshold, worked

QLD works differently in a way that catches people out if they assume it mirrors NSW. Instead of a threshold apportioned by each state’s wage share, QLD calculates a deduction based on your total Australian wages, then subtracts that deduction directly from your QLD wages. Take a QLD-only business with $7,000,000 in wages for the full year — above QLD’s $6,500,000 tier threshold, so the higher 4.95% rate applies instead of 4.75%. The deduction available at that wage level works out to $485,714 — smaller than the maximum $1,300,000, because the deduction itself shrinks as Australian wages climb — leaving $6,514,286 taxable and an estimated annual liability of $322,457.

A separate mental health levy applies on top for large employers. Take a QLD-only business with $10,500,000 in wages — above the levy’s primary threshold — and the estimated liability rises to $521,000, including a mental health levy component of roughly $1,250. This levy is layered on top of the base rate calculation, not blended into it, which is why QLD results sometimes show a separate line item that NSW and VIC results don’t.

The same wage bill, run through all three states

To make the contrast concrete, take a single hypothetical wage bill of $2,000,000 for the full financial year, and run it entirely through each state’s formula in turn, as if that were the only state the business operated in:

Three genuinely different results from an identical input, because the underlying mechanics — not just the headline numbers — differ. This is the practical reason a side-by-side comparison tool earns its place over reading three separate rate pages: the gap between these figures isn’t visible from the threshold and rate alone, only from running the actual calculation each state uses. It’s also why this figure will shift for your business depending on your specific wage level — these three results are only valid at exactly $2,000,000; a different total wage bill would produce a different ranking between the three states, particularly once VIC’s phase-out or QLD’s higher rate tier come into play at larger wage levels.

Common mistakes when comparing the three

• Assuming QLD apportions its threshold the way NSW and VIC do. It doesn’t — the deduction is calculated from total Australian wages and subtracted directly from QLD wages, without a separate wage-share apportionment step.
• Comparing headline thresholds without the rate. A bigger threshold with a higher rate doesn’t automatically mean a lower total bill — the two figures have to be considered together, at your actual wage level.
• Assuming VIC’s phase-out applies to a typical small business. It only bites once total Australian wages reach VIC’s phase-out start point — well above the range most SMB users of this site are operating in.
• Overlooking QLD’s mental health levy as a separate cost. It’s additional to the base rate calculation, not included in the headline 4.75% figure.
• Eyeballing which state is “cheaper” from the rate table alone. Because the three states differ in calculation shape, not just numbers, the cheapest state for a given wage bill isn’t always the one with the lowest headline rate or highest threshold.

Regional and large-employer variations not modelled here

This comparison — and this site’s calculators — cover the core threshold, rate and deduction mechanics for each state. A small number of edge cases sit outside that scope deliberately rather than being silently estimated: VIC’s reduced regional employer rate, and VIC’s large-employer payroll tax surcharge for very large wage bills, are both noted in our rate configuration as not modelled in this comparison. If either applies to your business, treat the figures here as a starting point and confirm the specific adjustment with SRO Victoria directly.

What to do next

1. Model your actual wage split — not a headline comparison — using the comparison calculator.
2. Don’t compare states on threshold or rate alone; the calculation shape differs enough that only a full run at your actual wage level gives a meaningful comparison.
3. If your business is grouped or pays wages in more than one state, layer that in before comparing — both change the threshold each state gives you.
4. If you’re a large employer approaching VIC’s phase-out band or QLD’s mental health levy thresholds, get specific advice rather than relying on the general mechanics described here.
