NSW Payroll Tax Audit Objection

The situation

Dr. Anh, 52, owns a three-doctor general practice in Parramatta. Her GPs are contractors, they always have been; the practice takes a service fee and the doctors bill Medicare directly. A Revenue NSW audit letter arrives requesting five years of practitioner agreements, service-fee records, and BAS statements. Eight months later: an assessment for AU$412,000, the practice's service arrangements are "relevant contracts" under PTA 041, the GPs' patient fees are deemed wages, and interest plus 25% penalty tax is included. She has 60 days to object, and the onus is on her. What Dr. Anh doesn't know: the relevant-contract exclusions are mechanical and evidence-driven (which doctors worked fewer than 90 days; which genuinely provide services to the public from multiple locations); CPN 036v2 may wipe much of the post-September-2024 liability via the bulk-billing rebate if her billing mix clears the threshold; penalty tax at 25% presumes lack of reasonable care she can rebut with her accountant's advice trail; and the objection document that carries her onus is a structured factual-legal argument, exactly the kind of document a AU$15k adviser builds from her records, or she doesn't build at all.

Who receives this

NSW SMBs assessed or under audit for payroll tax on contractor or grouping grounds, medical/dental/allied-health practices (the enforcement wave's center), trades and construction businesses using subcontractors, IT/consulting firms, franchise groups near the AU$1.2M threshold; secondarily their accountants (the natural channel).

Why the agency will not advise you

Revenue NSW audits, assesses, and decides objections, it publishes the rulings but cannot coach objectors against its own assessments. The adviser band prices for the AU$400k assessment, not the AU$60k one. The exclusions, de-grouping factors, and rebate rules are published and mechanical, a structured tool can carry the evidence-organisation load that is most of the work.

When to bring in a professional

Self-serve responses fit routine cases: clear facts, amounts a business can absorb, and a deadline still ahead of you. Bring in a licensed professional when the amount at stake is large relative to their fee, the facts are genuinely disputed, criminal exposure is possible, or the deadline has already passed. A short paid consultation to sanity-check your plan is often worth it even when you handle the filing yourself.
