Taxation and excise

The idea

A tax is a compulsory exaction of money by a public authority for public purposes, enforceable by law and not a payment for services rendered (Matthews as glossed in Air Caledonie). Every question in this topic tests the exaction against that definition. The named parties can call it a licence or a fee, and the characterisation is decided by substance rather than by the label.

The attributes are indicia rather than elements. Neither exaction by a public authority nor payment into the Consolidated Revenue Fund is essential (Australian Tape Manufacturers; Luton). What matters is the overall character, weighed factor by factor.

Two polities can impose an exaction, and each raises different questions. When the Commonwealth imposes it, three issues follow: whether s 51(ii) supports the law, whether the tax discriminates between States, and whether s 55 has been breached. When a State imposes it one issue dominates, whether the exaction is a duty of excise that s 90 reserves to the Commonwealth.

Where it comes from

The definition comes from Latham CJ in Matthews, refined through a line of exaction cases. Air Caledonie glossed it and supplied the test for a fee for services. The disqualifying characters were then built case by case. A fee for services requires that the payer acquire something and that the amount bear a discernible relationship to its value (Air Caledonie at 467). A charge for a privilege over a limited public natural resource is a royalty (Harper). A scheme that collects and passes on existing private liabilities confers no financial benefit on the polity and is not a tax (Luton). An exaction paid to a private body can still be a tax where its purpose is public (Australian Tape Manufacturers).

The excise line runs from Parton, where Dixon J tied s 90 to real control of the taxation of commodities, through Ha and into Vanderstock. Ha fixed the modern meaning of excise, and Vanderstock extended it to taxes on the use and consumption of goods.

How it is examined

A tax or excise issue appears in six of the seven papers from 2019 to 2025, worth 10 to 24 marks. It usually opens a State scheme question with an s 92 or discrimination issue beside it.

The exaction is always given a harmless name such as a licence, an inspection fee or a registration fee. The label is bait. The marks concentrate in two places. The first is whether the exaction is a tax at all. The second is whether, for a State tax, the franchise fee exception saves it.

The threshold deserves a third of the words at most. The excise characterisation and the exception's decay factors carry the rest. One recent shift matters. Use is now live, so the 2024 paper taxed the use of a barbeque and the pass answer wrongly treated use as outside s 90. Vanderstock closes that route.

How to argue it

Work the exaction through a fixed sequence.

1. Name the polity that imposed the exaction. A Commonwealth exaction raises s 51(ii) support, discrimination and s 55. A State exaction raises s 90.
2. Decide whether the exaction is a tax. State the positive attributes, then test each disqualifying character the facts make live: a fee for services, a royalty, a penalty, or the enforcement of private liabilities. Quote the planted figure when you do.
3. Attribute the competing readings. The State will argue the payer acquires a service or a privilege (Airservices; Harper). The challenger will answer that the amount bears no discernible relationship to the value acquired (Air Caledonie). The better view follows the purpose rather than the payee (Australian Tape Manufacturers).
4. On the Commonwealth path, if the exaction is not a tax then s 51(ii) does not support it. If it is a tax lodged in a non taxation Act, s 55 strikes that provision and the rest of the Act stands. Then check for discrimination between States.
5. On the State path, ask whether the tax falls on a step in the production, manufacture, sale, distribution or use of goods. If it does it is an excise under Ha and Vanderstock. No arithmetical relationship to the goods is needed where a large flat fee precedes production and enters the price (Hematite). Each step is independent, so ruling out a tax on production proves nothing about a tax on sale.
6. If the exaction is an excise, the only escape is a genuine franchise fee (Dennis Hotels). Run the decay factors both ways: the length of the licence period, the size of the rate, the lag before assessment, and whether the scheme genuinely regulates the business. The closer the fee sits to Ha and the further from the scheme Dennis Hotels upheld, the weaker the exception.
7. Split a composite scheme and test each component separately (Dennis Hotels).

Practice problems

One hundred exam-style problems across twelve topics. Pick a topic, read the problem, write your own answer in IRAC, then reveal the Pass and H1 exemplars and the examiner's comments. Step through in order or jump to a random one. Nothing you type is saved or sent anywhere.

The trap

The costliest error is treating the label as the answer. Every paper calls its exaction a licence, an inspection fee or a registration fee, and in Ha a one hundred per cent impost was still a revenue tax under an insubstantial cloak. Characterise by substance and quote the planted figure when you do.

A second error is now common. Notes written before 2023 treat a tax on use or consumption as outside s 90, and Vanderstock closes that route. The 2024 paper tested it within a year of the decision, so treat use as a step that attracts s 90 like any other.

Key authorities

• Matthews v Chicory Marketing Board — a tax is a compulsory exaction of money by a public authority for public purposes.
• Air Caledonie v Commonwealth — a clearance fee on incoming passengers was a tax. A fee for services needs a discernible relationship to value.★
• Airservices Australia v Canadian Airlines — cost recovery pricing by a statutory provider can stay a fee for services despite disproportion to marginal cost.★
• Australian Tape Manufacturers v Commonwealth — an exaction payable to a private body for a public purpose can still be a tax.★
• Luton v Lessels — a mechanism that collects and passes on private liabilities confers no benefit on the Commonwealth and is not a tax.★
• Harper v Minister for Sea Fisheries — a charge for a privilege over a limited natural resource is a royalty rather than a tax.★
• s 55 — a taxing provision inserted into a non taxation Act is struck down while the rest of the Act stands.★
• Ha v New South Wales — an excise is an inland tax on a step in the production, manufacture, sale or distribution of goods, extended to use in Vanderstock.★
• Hematite Petroleum v Victoria — no arithmetical relationship to the goods is needed where a large flat fee precedes production and enters the price.★
• Vanderstock v Victoria — a tax on the use or consumption of goods is an excise.★
• Dennis Hotels v Victoria — a prior period licence fee survives s 90 only where substantially identical to schemes already upheld.★
