Goods and Services Tax for Business and Property Transactions
GST becomes manageable when every transaction is classified before it is calculated. The recurring question is not simply whether a business has made money. It is whether the facts disclose a taxable supply, a GST-free supply, an input-taxed supply, a creditable acquisition, a taxable importation or an adjustment, and what the GST Act then requires.
1. The statutory architecture: what a strong GST answer does
The primary legislation is the A New Tax System (Goods and Services Tax) Act 1999 (Cth) (GST Act). A problem should be broken into separate supplies and acquisitions. For each outgoing supply, ask whether s 9-5 is satisfied. For each business acquisition, ask whether s 11-5 and the creditable-purpose rule in s 11-15 are satisfied. Then test the special regimes: GST-free supplies in Division 38, input-taxed supplies in Division 40, importations in Divisions 13 and 15, adjustments, deposits and property rules.
| Provision | Function | Exam / tutorial trigger |
|---|---|---|
| s 9-5 | Taxable supply | Consideration + enterprise + indirect tax zone + registration, unless GST-free/input taxed |
| ss 9-70, 9-75 | Amount/value | 10% of value; usually 1/11 of GST-inclusive price |
| Div 11 | Creditable acquisitions | Input tax credits for acquisitions made for a creditable purpose |
| Div 23; Div 188 | Registration / turnover | Current and projected GST turnover; exclusions matter |
| Div 38 | GST-free | No GST on supply; related credits generally preserved |
| Div 40 | Input taxed | No GST on supply; related credits generally denied |
| Divs 13, 15 | Importations | GST at border; possible matching credit for registered business importer |
| Div 72 | Associates | Supplies for no / inadequate consideration can still be taxable |
| Div 75 | Margin scheme | Special GST calculation for eligible real-property supplies |
| Div 99 | Security deposits | GST deferred until deposit is forfeited or applied as consideration |
2. Registration: enterprise first, turnover second
Under s 23-5, an entity is required to register if it is carrying on an enterprise and its GST turnover meets the registration turnover threshold. The current ordinary threshold is $75,000, set by reg 23-15.01 of the GST Regulations 2019; the non-profit threshold is $150,000. Division 188 requires both current GST turnover and projected GST turnover to be understood. The supplied reading specifically identifies GSTR 2001/7 as the key ruling on GST turnover.
Do not add every receipt in the taxpayer's life. Employment remuneration is not a supply in the course of the employee's own enterprise. Input-taxed supplies are excluded from current and projected GST turnover. This is why ordinary residential rent is treated differently from taxable commercial studio hire. A strong answer therefore classifies each stream before adding figures.
3. Taxable supplies: s 9-5 must be worked element by element
A supply is taxable if: (a) it is for consideration; (b) it is made in the course or furtherance of an enterprise carried on by the supplier; (c) it is connected with the indirect tax zone; and (d) the supplier is registered or required to be registered. Even then, the supply is not taxable to the extent it is GST-free or input taxed. In a high-quality answer, each element is tied to a fact.
Consideration can be monetary or non-monetary. Section 9-75 values non-cash consideration by reference to its GST-inclusive market value. That is why barter can produce GST even where no cash changes hands.
4. Creditable acquisitions and input tax credits
Section 11-5 requires an acquisition; a creditable purpose; a taxable supply to the acquirer; consideration; and registration/required registration. Section 11-15 denies creditable purpose to the extent an acquisition relates to input-taxed supplies or is private/domestic. The input tax credit is generally the GST payable on the supply, subject to apportionment and special rules.
This explains the tutorial distinctions: business materials from a registered supplier can generate a credit; a kiln used wholly in a taxable enterprise can generate a full credit; a phone used 60% for business is only partly creditable; wages are not ordinary taxable supplies by employees; interest commonly relates to input-taxed financial supplies; and a purchase from an unregistered supplier carries no GST merely because the purchaser is registered.
5. GST-free and input taxed: same customer-facing GST, different upstream consequence
Both categories ordinarily mean no GST is charged to the customer, but their input-tax-credit consequences are fundamentally different. GST-free supplies generally preserve credits for related acquisitions. Input-taxed supplies generally deny credits to the extent acquisitions relate to making those supplies. This is one of the most important distinctions in the topic.
Food - Subdivision 38-A
Section 38-2 makes qualifying food GST-free, but s 38-3 and Schedules 1 and 2 create important exclusions and beverage rules. Basic fresh fruit is ordinarily GST-free. Cakes, sandwiches and hot takeaway food are commonly taxable. Beverage classification requires close attention: qualifying fruit/vegetable juice and specified water can be GST-free, while prepared coffee and flavoured/carbonated drinks are commonly taxable. Food supplied for consumption on the premises is excluded from GST-free treatment. The fact that tables exist is not enough by itself; the issue is whether the particular supply is for consumption on those premises.
Education - Subdivision 38-C
Qualifying education-course tuition can be GST-free under s 38-85. Course materials supplied by the course provider and necessarily consumed or transformed by students can be GST-free under s 38-95. A textbook retained after the course and a laptop from an ordinary retailer are not made GST-free merely because they are used for study.
Health - Subdivision 38-B
A qualifying medical service is GST-free under s 38-7. The statutory definition and exclusions must still be checked, particularly for services outside the Medicare-linked professional-service framework or cosmetic services.
Residential premises - Division 40
Ordinary residential rent is generally input taxed under s 40-35. Sales of existing residential premises are generally input taxed under s 40-65, while sales of new residential premises under s 40-75 can be taxable. GSTR 2012/5 is the key supplied ruling on residential premises; GSTR 2012/6 addresses commercial residential premises.
6. Mixed and composite supplies: apportionment is a legal characterisation exercise
The supplied materials distinguish a mixed supply, where separately identifiable taxable and non-taxable components require reasonable apportionment, from a composite supply, where a minor or incidental component follows the character of the dominant supply. GSTR 2001/8 is the supplied authority for apportioning consideration between taxable and non-taxable parts.
7. Non-cash consideration, gifts and associates
Barter does not escape GST. A registered landscape designer who performs a taxable service in exchange for private accommodation vouchers may still have output GST because the vouchers are non-monetary consideration. Whether the recipient has any input tax credit is a separate question and depends on creditable purpose and the GST status of the reciprocal supply.
Gifts to associates require extra care. Division 72 can make a supply to an associate taxable even without consideration where the associate is unregistered or does not acquire solely for a creditable purpose. Under s 72-10 the value is the GST-exclusive market value. This is an important precision point in the Sophie and Amelia tutorial problems: if the question does not give market value, a fully exact Division 72 calculation may require an additional fact. Private-use adjustment provisions can also be relevant depending on exactly what was acquired and later applied privately.
8. Going concerns: s 38-325
A sale of a business is not automatically GST-free. Under s 38-325, the supply must be for consideration; the recipient must be registered or required to be registered; the parties must agree in writing that the supply is of a going concern; the supplier must supply all things necessary for continued operation of the identified enterprise; and the supplier must carry on that enterprise until the day of supply. GSTR 2002/5 is the central supplied ruling.
The practical lesson is contractual. Registration, written agreement, necessary assets, premises, systems, goodwill and continuity of operation should be addressed before settlement. A mere statement that the seller is transferring "the business and assets" does not itself establish the statutory conditions.
9. Security deposits and ordinary part-payments
Division 99 applies only to a deposit genuinely held as security for performance. An ordinary non-refundable part-payment is consideration immediately and follows the normal attribution rules. A genuine security deposit is not treated as consideration until it is forfeited or applied. GSTR 2006/2 and GSTR 2009/3 are the supplied rulings. Where part of a security deposit is applied to a specific charge such as repairs or extraordinary wear, that amount can become consideration for that identifiable supply.
10. Taxable importations and creditable importations
Under s 13-5, a taxable importation generally arises when goods are imported and entered for home consumption, unless the importation is non-taxable. GST on a taxable importation is 10% of the statutory value under s 13-20, which includes customs value, relevant international transport/insurance and customs duty. Registration is not required for the importation itself. Division 15 then asks whether a registered importer has made a creditable importation, allowing a matching input tax credit where the goods are imported for a creditable purpose. GSTR 2003/15 is the supplied ruling.
11. Property: new residential premises, margin scheme and purchaser consequences
Property questions often involve several regimes at once. First characterise the property under Division 40. New residential premises can be taxable, whereas existing residential premises are generally input taxed. GSTR 2003/3 is the supplied ruling dealing with new residential premises.
Division 75 then permits the margin scheme for eligible taxable supplies of real property. The margin scheme is not an accounting-profit calculation. Under the basic method in s 75-10, GST is generally 1/11 of the statutory margin, and the margin is generally consideration for the supply less the relevant consideration for the acquisition, subject to the detailed statutory rules. Development costs do not simply reduce the margin; they are dealt with separately, including through available input tax credits. The supplier and recipient must agree in writing to use the margin scheme on or before the supply (or within a further period allowed by the Commissioner). GSTR 2006/8 is the supplied ruling.
A recipient who acquires real property under the margin scheme is not entitled to an input tax credit for that acquisition under s 75-20. For new residential premises, the purchaser withholding regime may also require attention separately from the supplier's final GST liability.
12. Adjustments and later changes
GST is not frozen forever at the first transaction. Division 19 contains the general adjustment-event framework. Divisions 129, 130 and 132 can become relevant where intended or actual use changes, goods are applied privately, or particular property rules produce an adjustment. The supplied reading identifies GSTR 2004/8 for decreasing adjustments under Division 132. A strong tutorial answer always asks whether a later event changes the original GST position.
