GST Act: The Act is deeply integrated with the A New Tax System (Goods and Services Tax) Act 1999. Most definitions (supply, enterprise, registration, connected with the indirect tax zone, net amount, consideration, and many others) are imported from the GST Act (section 27-1). Attribution rules for LCT cross-reference GST attribution rules (sections 13-15 and 13-10). LCT amounts are incorporated into GST net amounts (section 13-5). Division 165 of the GST Act anti-avoidance provisions apply to LCT on importations (section 13-30).
Imposition Acts: LCT is imposed by three separate Acts: the A New Tax System (Luxury Car Tax Imposition-General) Act 1999, the A New Tax System (Luxury Car Tax Imposition-Customs) Act 1999, and the A New Tax System (Luxury Car Tax Imposition-Excise) Act 1999. The rate applicable under whichever of those Acts covers the supply or importation determines the multiplier in the LCT formula in sections 5-15 and 7-15.
Taxation Administration Act 1953: Parts 3-10, 4-1 and 4-15 in Schedule 1 to the TAA 1953 contain administration, collection, and recovery provisions. The general interest charge under section 105-80 of that Schedule applies to excess credits treated as LCT payable under section 17-15. Assessment of LCT on importations is covered by Division 155 of Schedule 1 to the TAA 1953.
Customs Act 1901: The customs value, entry for home consumption, and the regime for securities and undertakings under sections 162 and 162A of the Customs Act all interact with the LCT importation rules. Security arrangements under those sections can defer LCT payment where goods are later re-exported (section 13-25).
Customs Tariff Act 1995: Schedule 4 items of the Customs Tariff Act 1995 exempt certain importations from LCT (section 7-10(3)).
Income Tax Assessment Act 1997: The definition of primary production business (section 995-1 of the ITAA 1997), approved form (section 995-1), and the indexation methodology for the luxury car tax threshold and fuel-efficient car limit (Subdivision 960-M) all come from the ITAA 1997.
Road Vehicle Standards Act 2018: The fuel consumption rating used to identify fuel-efficient cars is measured under national road vehicle standards in force under section 12 of the Road Vehicle Standards Act 2018 (section 25-1(4)).
A New Tax System (Australian Business Number) Act 1999: The ABN used in quoting is defined by section 41 of the ABN Act (section 27-1). Section 23 of that Act provides penalties for misuse of ABNs (Note 3 to section 9-30).
