Medical Practice Payroll Tax — Victoria

What this means for your practice

If 60% of your GP service income is bulk-billed, then 60% of your GP wages are exempt from payroll tax. The remaining 40% is taxable and tested against the $1,000,000 threshold (which phases out between $3M and $5M of Australian wages). Non-GP specialists, dentists, physiotherapists, psychologists and other allied health are not covered — their payments under relevant contracts remain fully taxable regardless of bulk-billing proportion.

Payroll tax threshold context

Victoria threshold: $1,000,000 (FY 2026/2027). Deemed wages plus employed staff wages are tested against this threshold.

Where Victorian deemed wages come from

Victorian deemed wages arise whenever a practice invoices in its own name and forwards the balance to a practitioner. The forwarded amount is the deemed wage; the GP share of it is then cut back by the proportional exemption, while every other practitioner's share stays in the base untouched.

The amount is struck practitioner by practitioner, and it is what is forwarded — gross billings less the retained fee — not the practitioner's drawings or the practice's own margin.

Measuring the Victorian exempt proportion

Victoria's exemption tracks bulk billing exactly: exempt GP wages equal the bulk-billed share of GP service income. A practice with 60% of its GP income bulk billed exempts 60% of its GP wages. The ratio is applied to wages, not to total billings.

Because the mix shifts through the year, the ratio should be recalculated each period. The annual reconciliation figure is the weighted proportion across the year, not the mean of twelve monthly percentages.

The Victorian disclosure obligation

Victoria is alone in requiring the exempt GP wage figure to be shown separately at annual reconciliation. An exemption claimed without that disclosure is an incomplete claim, and the SRO can test the reported figure against the practice's own bulk-billing data.

A practice therefore needs a payroll process that splits GP wages into exempt and taxable parts each period, so the disclosed figure comes out of the records rather than being rebuilt at year end.

Practitioners the Victorian exemption leaves out

The exemption is drawn around GPs and GP registrars. Specialists, dentists, physiotherapists, psychologists and allied health practitioners are all outside it, and their contract payments remain fully taxable however high the practice's bulk-billing rate climbs.

A mixed practice has to keep the GP cohort separable from the rest in its payroll system; without that split it cannot apply the exemption it is entitled to.

What a Victorian practice should keep on file

A Victorian practice should be able to produce the Service Facility Agreements, the working that derives the bulk-billed proportion of GP service income, and the reconciliation showing how the exempt figure was reached and reported.

One further fact needs establishing: whether the practice has already heard from the SRO. Retrospective relief to 30 June 2025 runs only to practices the SRO had not previously advised.

Where Victorian positions go wrong

The commonest errors are extending the exemption to all practitioner payments instead of the GP cohort, and reporting the exemption without the separate exempt-wage disclosure. The first inflates the benefit; the second leaves the claim incomplete.

A third is overlooking the threshold phase-out. A practice inside a national group above $3,000,000 of Australian wages has a reduced deduction, and the group's growth — not the practice's payroll — governs how much.

Victoria's exemption reaches employed GPs as well as contractors

Victoria exempts wages paid to GPs and GP registrars whether they are contractors or employees, which sets it apart from the contractor-focused relief elsewhere. A practice cannot sidestep the exemption question by putting doctors on its own payroll: where an employed GP bulk bills, the attributable part of that GP's wages is exempt on the same proportional basis as a contractor's remittances.

The corollary is that the practice must attribute wages to bulk-billed work for both groups. For a contractor the attribution runs off the remittance; for an employed GP it runs off the practitioner's own service data. A practice that tracks bulk billing only at practice level, rather than by GP, cannot compute the exempt portion for an employed cohort.

Classifying a Victorian consultation that is not cleanly bulk billed

The Victorian exemption turns on the fully funded share of GP work, and not every consultation is cleanly one thing or the other. Where a practice charges a gap, or where a service is only partly funded, the proportion is less obvious than the headline figure suggests, and the practice should be able to classify each service rather than estimate the split.

Where the classification is genuinely mixed, the practice should document the method it used and apply it consistently across periods. An inconsistent method is harder to defend on review than a conservative one applied throughout, because the SRO can test the reported exempt figure against the practice's own data.

What a Victorian practice should have in place before its first exempt return

Before the first return that carries the exemption, a Victorian practice should have three things: a payroll split that separates GP wages from all other wages, a method for deriving the bulk-billed proportion from service data, and a reconciliation that ties the exempt figure to the reported total. Without the split the exemption cannot be applied at all; without the method the disclosed figure is an estimate.

The disclosure obligation makes this concrete. Because the exempt GP wage figure is reported separately at reconciliation, the practice's own return is the first place an error shows. A process that produces the figure from the ordinary payroll run avoids the year-end reconstruction that so often fails to reconcile.

A worked Victorian medical scenario

Take a Victorian practice with $700,000 of employed staff wages and $1,200,000 of GP payments, with 60% of GP service income bulk billed. The exemption removes 60% of the GP wages — $720,000 — leaving $480,000 of taxable GP wages. Added to the $700,000 of staff wages, the taxable total is $1,180,000. The $1,000,000 threshold applies in full because the group's national wages are below the $3,000,000 phase-out start, so $180,000 is taxed at 4.85% — $8,730.

Move the same practice into a group with $4,000,000 of national wages and the deduction halves to $500,000. The taxable amount rises to $680,000 and the liability to $32,980 — a larger change than most movements in the bulk-billing proportion would produce.
