Northern Territory payroll tax threshold history

Since FY 2021/2022, the annual payroll tax threshold in Northern Territory has risen 66.7%. In FY 2026/2027 it is $2,500,000. The table below shows the threshold and headline rate for every financial year currently tracked in the engine. These values are drawn directly from the statutory registry, so if a legislative amendment is recorded there it will automatically appear here.

Rates and thresholds should be confirmed against the official Payroll Tax Act 2009 (NT)and the relevant state revenue office website before lodgement.

The NT has the highest threshold in the country

From 1 July 2025 the Northern Territory threshold is $2,500,000, with a diminishing taper of $1 for every $2 of Australian wages above it, reaching nil at $7,500,000. Older references to a $1.5M flat threshold are out of date and will understate the shelter available to a practice.

At $2,500,000 of NT wages a practice pays nothing at all — the calculator's example at exactly the threshold returns zero. At $4,000,000 the apportioned deduction is $1,750,000, the taxable amount is $2,250,000, and the liability is $123,750. Because the threshold is the highest in the country and there is no medical-specific relief, most NT practices sit below it, and the deemed wages question, while real, does not produce a liability.

The 6.5% large-employer rate is tested at group level

From 1 July 2026 a 6.5% rate applies where Australian-wide group wages reach $100,000,000. The test is at group level and is not prorated for a part-year. The standard rate remains 5.50%.

That means an individual NT employer with wages far below $100,000,000 can pay 6.5% if the group it belongs to exceeds the threshold nationally. A practice connected to a larger corporate group — through common control, common directors or shared employees — should establish the group's total Australian wages before assuming the standard rate applies.

The NT's two practical quirks

The Northern Territory is the only jurisdiction that does not require monthly returns by the 7th of the following month. Its returns are due on the 21st. Practices running a single national lodgement calendar routinely get this wrong, and the error is entirely avoidable.

Apprentice and trainee wages are also exempt from 1 July 2025. The exemption has to be applied before the threshold and rate, not after — excluding those wages from taxable wages can move a practice below the apportioned threshold entirely. There is no medical-specific guidance for the NT, and the apprentice and trainee exemption is the only sector-adjacent relief available.

Who is caught in the NT, and who is not

The Northern Territory has no medical-specific relief, so the relevant contract provisions apply to every practitioner type. A GP engaged under a Service Facility Agreement where the practice bills and remits produces deemed wages in the NT just as a specialist, dentist or allied health practitioner would. The GP exemption that exists in Queensland, Victoria, South Australia and the ACT does not exist here.

The saving grace is the threshold. At $2,500,000, combined with employed staff wages, most NT practices sit below the apportioned threshold and pay nothing. The question that matters is therefore not whether deemed wages arise — they usually do — but whether the practice's total taxable wages cross the threshold. A practice with a large contractor cohort and a growing staff payroll should model the combined figure rather than assuming the threshold absorbs it indefinitely.

How the NT's taper interacts with grouping

The NT's deduction tapers by $1 for every $2 of Australian group wages above $2,500,000 and reaches nil at $7,500,000. In a group the deduction is then apportioned by the NT's share of national wages, so an interstate group can reduce an NT practice's shelter even where the NT wages themselves are well below $2,500,000.

A group with $5,000,000 of Australian wages and $2,000,000 of NT wages has a tapered deduction of $1,250,000 before apportionment — the $2,500,000 threshold reduced by $1 for every $2 of the $2,500,000 excess. Apportioned by the NT's 40% share of national wages, the deduction is $500,000, leaving $1,500,000 taxed at 5.50% — $82,500.

The NT practice's own payroll did not change between the two positions; only the group's national wages did. That is the effect of the apportionment rule, and it is the reason an NT practice inside a growing group should model the group total rather than its own wages alone.
