and\n\n(b) any instrument made or having effect under a law referred to in paragraph (a)—\n\nbut does not include a law of the Commonwealth, whether written or unwritten, or an instrument made or having effect under such a law;\n\n***State taxing law*** means a State law that is a State taxing law within the meaning of the Commonwealth Act.\n\n\t4 This Act binds the Crown\n\ns. 4\n\nThis Act binds the Crown in right of the State and, in so far as the legislative power of the State permits, in all its other capacities.\n\n_______________\n\nPart 2—Administration and Operation of State Taxing Laws as Applied Laws in Relation to Commonwealth Places\n\n\t5 Arrangements with Commonwealth\n\ns. 5\n\nThe Governor may make an arrangement with the Governor-General of the Commonwealth in relation to the exercise or performance of a power, duty or function (not being a power, duty or function involving the exercise of judicial power) by a State authority under an applied law.\n\n\t6 Variation and revocation of arrangements\n\nThe Governor may arrange with the Governor-General for the variation or revocation of an arrangement made under section 5.\n\n\t7 Exercise of powers etc. by State authorities\n\nDespite any State law, a State authority has any power, duty or function that the Commonwealth Act authorises or requires the authority to exercise or perform.\n\nS. 7A inserted by No. 69/2013 s. 3.\n\n\t7A Modified operation of State taxing laws\n\n(1) If, in relation to a State taxing law, there is a corresponding applied law, the State taxing law is to be read and construed with any modifications that are necessary or convenient for any of the following purposes—\n\n(a) for the purpose of enabling the effective operation of the State taxing law in conjunction with the corresponding applied law;\n\n(b) for the purpose of enabling the State taxing law to operate so that a taxpayer has a combined liability under—\n\n(i) the State taxing law; and\n\n(ii) the corresponding applied law—\n\nthat is as nearly as possible the same as the taxpayer's liability would be under the State taxing law alone if the Commonwealth places in the State were not Commonwealth places.\n\n(2) If a State taxing law applies to an event, state of affairs or transaction that occurred, existed or was entered into on or after 30 January 2001, then, to the extent of any inconsistency, the modifications (if any) to the State taxing law that have effect under this section in relation to the event, state of affairs or transaction prevail over the amendments (if any) to the State taxing law made by section 19.\n\n**Note**\n\nSection 19 of this Act amended the **Debits Tax Act 1990**, the **Financial Institutions Duty Act 1982**, the **Pay-roll Tax Act 1971**, the **Stamps Act 1958** and the **Taxation Administration Act 1997**.\n\nS. 7B inserted by No. 69/2013 s. 3.\n\n\t7B Actions taken under corresponding applied law\n\ns. 7B\n\n(1) A person is not required to take an action in relation to an event, state of affairs or transaction that is otherwise required or permitted, or could be required or permitted, under a State taxing law that applies, or could apply, to any extent, to or in relation to the event, state of affairs or transaction if—\n\n(a) a corresponding applied law applies, or could apply, to any extent, to or in relation to the same event, state of affairs or transaction; and\n\n(b) the person is required or permitted, or could be required or permitted, to take the action under both the State taxing law and the corresponding applied law in relation to the event, state of affairs or transaction; and\n\n(c) the person has taken the action in accordance with the corresponding applied law; and\n\n(d) the Commissioner of State Revenue has sufficient information about the event, state of affairs or transaction to carry out his or her functions in relation to it under the State taxing law or the corresponding applied law or both, as the case requires.\n\n(2) If subsection (1) applies to a person in relation to an event, state of affairs or transaction, the Commissioner of State Revenue may carry out his or her functions in relation to the event, state of affairs or transaction as if the person had taken whatever action is required or permitted under the State taxing law in relation to the event, state of affairs or transaction.\n\ns. 7B\n\n_______________\n\nPart 3—Proceedings\n\n\t8 Continuation of proceedings if place found not to be a Commonwealth place\n\ns. 8\n\nIf—\n\n(a) proceedings have been commenced in a court under a law as an applied law; and\n\n(b) the court is satisfied that the State taxing law that corresponds to that law is not excluded by section 52(i) of the Commonwealth Constitution—\n\nthen the proceedings must be continued as though they had been commenced under the State taxing law.\n\n\t9 Objection not allowable on ground of duplicate proceedings\n\nIn any proceedings under a State taxing law, an objection must not be allowed merely on the ground that proceedings have been commenced, or are pending, under a corresponding applied law.\n\n\t10 Proceedings on certain appeals\n\n(1) This section applies to an appeal from a judgment, decree, order or sentence of a court in proceedings under a law as an applied law.\n\n(2) If the court is satisfied that the State taxing law that corresponds to that law is not excluded by section 52(i) of the Commonwealth Constitution, then the court must deal with the appeal as though—\n\n(a) the proceedings in relation to which the appeal was brought had been brought under the State taxing law; and\n\n(b) the judgment, decree, order or sentence had been given or made in proceedings brought under the State taxing law.\n\n\t11 Certificates about ownership of land\n\ns. 11\n\n(1) In proceedings under a State taxing law (or purporting to be under a State taxing law) in which any question arises as to whether a place is a Commonwealth place, a certificate in writing given by an authorised person about any of the following matters relating to land is evidence of the matters stated in the certificate—\n\n(a) the ownership of the land, or of an estate or interest in the land, on a date or during a period specified in the certificate;\n\n(b) the existence and ownership of a right in respect of the land, on a date or during a period specified in the certificate.\n\n(2) A document that purports to be a certificate referred to in subsection (1) is to be regarded as being such a certificate, and to have been duly given, unless the contrary is proved.\n\n(3) In this section—\n\n***authorised person*** means a person who is a delegate, in respect of any power or function, under section 139 of the Lands Acquisition Act 1989 of the Commonwealth.\n\n_______________\n\nPart 4—Validation and Saving\n\n\t12 Validation of things purportedly done under an applied law\n\ns. 12\n\nIf—\n\n(a) something purports to have been done under a law as an applied law; and\n\n(b) the State taxing law that corresponds to that law is not excluded by section 52(i) of the Commonwealth Constitution—\n\nthen that thing is to be regarded as having been done under the State taxing law.\n\n\t13 Provisions as to operation of applied law and State taxing law if a place ceases to be a Commonwealth place\n\n(1) This section applies if an applied law ceases, or ceased, to have effect in relation to a place at a particular time because the place ceases, or ceased, to be a Commonwealth place at that time.\n\n(2) The State taxing law to which the applied law corresponded immediately before that time—\n\n(a) applies, or is to be regarded as having applied, in relation to that place from that time; and\n\n(b) is to be read and construed as though it provided expressly that it was intended to apply in relation to the place from that time.\n\n(3) The following things are not affected—\n\n(a) any right, privilege, obligation or liability acquired, accrued or incurred under the applied law;\n\n(b) any penalty, forfeiture or punishment incurred in respect of an offence against the applied law;\n\n(c) any investigation, legal proceeding or remedy in respect of any right, privilege, obligation, liability, penalty, forfeiture or punishment referred to in paragraph (a) or (b).\n\n(4) Any penalty, forfeiture or punishment referred to in subsection (3)(b) may be imposed as if the applied law had not ceased to have effect.\n\n(5) An investigation, legal proceeding or remedy referred to in subsection (3)(c) may be instituted, continued or enforced as if the applied law had not ceased to have effect.\n\n\t14 Provisions as to operation of State taxing law if a place becomes a Commonwealth place\n\ns. 14\n\n(1) This section applies if a State taxing law ceases, or ceased, to have effect in relation to a place at a particular time because the place becomes, or became, a Commonwealth place at that time.\n\n(2) The following things are not affected—\n\n(a) the previous operation of the State taxing law before that time;\n\n(b) any right, privilege, obligation or liability acquired, accrued or incurred under the State taxing law;\n\n(c) any penalty, forfeiture or punishment incurred in respect of an offence against the State taxing law;\n\n(d) any investigation, legal proceeding or remedy in respect of any right, privilege, obligation, liability, penalty, forfeiture or punishment referred to in paragraph (b) or (c).\n\n(3) Any penalty, forfeiture or punishment referred to in subsection (2)(c) may be imposed as if the State taxing law had not ceased to have effect.\n\n(4) An investigation, legal proceeding or remedy referred to in subsection (2)(d) may be instituted, continued or enforced as if the State taxing law had not ceased to have effect.\n\ns. 14\n\n_______________\n\nPart 5—Miscellaneous\n\n\t15 Instruments referring to applied law\n\ns. 15\n\n(1) This section applies to an instrument or other writing that relates to an act, matter or thing that has a connection with a Commonwealth place.\n\n(2) In so far as—\n\n(a) the instrument or writing contains a reference to a law as an applied law; and\n\n(b) the State taxing law that corresponds to that law is not excluded by section 52(i) of the Commonwealth Constitution—\n\nthe reference has effect as if it were a reference to the State taxing law.\n\n\t16 Appropriation\n\nAny liability of the State—\n\n(a) to pay money to the Commonwealth to enable it to comply with section 23(1) of the Commonwealth Act; or\n\n(b) under an arrangement with the Commonwealth under section 5—\n\nis to be met out of the Consolidated Fund which is appropriated to the necessary extent.\n\n\t17 Double jeopardy\n\nIf an act or omission constitutes an offence under both a law of the State and an applied law and the offender has been punished for the offence under the applied law, the offender shall not be liable to be punished for the offence under the law of the State.\n\n\t18 Regulations\n\ns. 18\n\nThe Governor in Council may make regulations for or with respect to any matter or thing necessary to be prescribed to give effect to this Act.\n\n_______________\n\nPt 6 (Heading and s. 19) repealed by No. 28/2007 s. 3(Sch. item 11).\n\n* * * * *\n\nSch. amended by No. 74/2000 s. 3(Sch. 1 item 23), repealed by No. 28/2007 s. 3(Sch. item 11).\n\n* * * * *\n\nSch.\n\n\n\nENDNOTES\n\nEndnotes\n\n1.

S. 2: The operation of this Act and the Commonwealth Act will depend on the making of an arrangement under section 5 of this Act and section 9 of the Commonwealth Act. As soon as the arrangement is made, the State taxing laws are taken to have always applied in relation to Commonwealth places in the State, but not so as to impose any liability for tax for things that happened before 6 October 1997.

Amendments (notably the 2013 inserts of ss 7A and 7B) added active interpretive rules requiring State taxing laws to be read with modifications to preserve combined taxpayer liability and to allow actions taken under corresponding Commonwealth applied laws to satisfy State law requirements (ss 7A–7B). Those additions move the Act from simply recognising mirror application to reshaping how State taxing laws operate in practice and reducing duplicate compliance — a substantive broadening of operational scope compared with the original, narrower purpose statement (s 1). The Act also contains validation/saving measures (ss 12–14) and appropriation rules (s 16) that further extend its practical effects on State administration and finances."},"complexity_factors":["Multiple cross-jurisdictional references: frequent cross‑references to the Commonwealth Places (Mirror Taxes) Act 1998 and to section 52(i) of the Commonwealth Constitution (affects interpretation throughout)","Defined terms concentrated in one section: ~14 defined expressions in s 3 (e.g. applied law, Commonwealth place, corresponding applied law, State authority)","Moderate number of Parts and provisions: 5 substantive Parts (plus repealed Pt 6), covering administration, proceedings, validation and miscellaneous topics","Conditional modification clauses: s 7A requires reading State taxing laws with modifications “necessary or convenient” and contains a prevailing‑over rule tied to specific amendment history (adds interpretive complexity)","Operational delegation and discretion: s 5 grants the Governor power to enter arrangements with the Commonwealth, and s 18 gives regulation‑making power — both create practical uncertainty about exact administrative arrangements","Evidentiary presumptions: s 11 deems certain Commonwealth certificates as evidence unless proved otherwise (legal effect and challenge points)","Interlocking validation and saving provisions: ss 12–14 validate past acts and preserve rights across status changes of places, creating temporal complexity","Procedural interactions: rules governing continuation/transfer of proceedings and appeals (ss 8–10) add litigation‑management complexity"],"plain_english_summary":"**What this law does (mechanics first)**\n\n- The Act makes rules for how State taxes operate in places in Victoria that are also Commonwealth places (land or property the Commonwealth has acquired for public purposes). It applies where the Commonwealth has made its own “mirror” version of a State taxing law (the Commonwealth Places (Mirror Taxes) Act 1998) and the State’s law is applied as a Commonwealth law in relation to those places (see the definitions and purpose: s 1, s 3).\n\n- The Governor of Victoria may enter into an arrangement with the Governor‑General to manage how State authorities exercise functions under those applied laws (s 5). The Governor can also vary or revoke those arrangements (s 6).\n\n- State authorities retain the powers, duties and functions the Commonwealth mirror regime authorises or requires them to exercise (s 7). The Act binds the Crown (s 4).\n\n- Where a State taxing law has an applied Commonwealth counterpart (a “corresponding applied law”), the State law is to be read with any modifications needed to make the two work together and to produce, as far as possible, the same combined tax liability a taxpayer would have had if the place had not become a Commonwealth place (s 7A).\n\n- If a taxpayer has done what is required under the corresponding Commonwealth applied law, they generally do not have to repeat the same action under the State law, provided the State revenue commissioner has enough information to perform their functions (s 7B).\n\n- The Act contains procedural and evidentiary rules for legal proceedings that involve whether a place is a Commonwealth place: proceedings begun under an applied law can continue under the State law if the court finds the State law is not excluded by s 52(i) of the Commonwealth Constitution (s 8, s 10). A written certificate from an authorised Commonwealth delegate about ownership or rights in land is taken as evidence unless disproved (s 11).\n\n- The Act validates acts done under an applied law as having been done under the State taxing law where the corresponding State law is not excluded by the Constitution (s 12). It preserves existing rights, liabilities, penalties and ongoing proceedings when a place changes status to or from a Commonwealth place (s 13, s 14).\n\n- Other practical points: references in instruments to an applied law are treated as references to the State law where appropriate (s 15); the State will meet any liabilities to pay the Commonwealth to honour the Commonwealth mirror obligations from Consolidated Fund appropriations (s 16); double jeopardy is prevented — a person punished under an applied law cannot be punished again under the State law for the same act (s 17); and the Governor in Council may make regulations to implement the Act (s 18).\n\n**Who this affects**\n\n- State and Commonwealth administrative bodies that collect or administer taxes in relation to Commonwealth places (courts, revenue offices, State or Commonwealth land administration delegates) (see s 3 definition of State authority, ss 5–7B, 11).\n- Taxpayers and businesses that own, occupy or transact in land or other assets that are or may become Commonwealth places, because their tax liability may be split or mirrored between State and Commonwealth regimes (see s 7A and s 7B).\n- The State government budget, to the extent the State meets payments to the Commonwealth under arrangements (s 16).\n\n**Why it matters (official rationale and how that plays out mechanically)**\n\n- Officially the Act exists to provide the administration and operation of State taxing laws when those laws are applied by the Commonwealth to Commonwealth places (s 1). Mechanically, it creates a legal framework so that State taxing rules and their Commonwealth-applied counterparts work together rather than producing duplication, gaps or uncertainty.\n\n- The Act tries to achieve two practical aims: (a) keep taxpayers’ combined liability as close as possible to what it would have been if the land had stayed purely under State law (s 7A), and (b) avoid forcing taxpayers or administrators to perform identical compliance steps twice if they have already acted under a corresponding applied law (s 7B).\n\n**Costs, incentives and trade‑offs — what to expect in practice**\n\n- Who pays: the State meets payments required to the Commonwealth under any arrangement from the Consolidated Fund (s 16). That creates a direct budgetary cost for the State where arrangements require payments.\n\n- Administrative incentives and burden: the Act centralises some decision‑making (the Governor negotiates arrangements: s 5) and gives the State revenue commissioner authority to accept actions done under the Commonwealth-applied law in lieu of duplicate State actions if the commissioner has sufficient information (s 7B). This reduces duplicate compliance for taxpayers but imposes an information‑sharing and recordkeeping requirement on revenue authorities (s 7B(d)).\n\n- Legal and implementation risk: the Act depends on an intergovernmental arrangement and on the constitutional question whether a particular State taxing law is “excluded by section 52(i)” of the Constitution (frequently litigated). That creates scope for disputes about whether a State or applied law governs a particular case (see ss 8, 10, 12, 13, 14). The Act builds procedural rules to manage that risk (e.g. certificates as prima facie evidence — s 11), but litigation over constitutional exclusion can still arise.\n\n- Effects on private enterprise and competition: the Act does not itself change tax rates or create new taxes. Its effects on businesses are administrative: it can reduce duplicative compliance and clarify liability where land changes status, but it also introduces additional complexity when determining whether a place is within State or Commonwealth taxing reach (ss 7A, 7B, 11, 13, 14). That may increase transaction costs for firms that deal with property transitioning between State and Commonwealth ownership or use.\n\n- Contract freedom and property dealings: the Act preserves prior rights, liabilities and proceedings when land changes status (ss 13–14). That reduces legal uncertainty for contractual counterparties but can create complexity in ongoing tax disputes about which law applies.\n\n- Concentrated benefits, diffuse costs: any administrative simplification mainly benefits affected taxpayers and revenue offices (concentrated). The State bears funding obligations to the Commonwealth (s 16) which are diffuse across the State budget.\n\n**Implementation discretion and enforcement mechanics**\n\n- The Act gives the Governor a role in arranging administration with the Commonwealth (s 5) and leaves implementation detail to regulations (s 18) and the State revenue office (s 7B). Courts are given rules for converting proceedings from applied law to State law where appropriate (ss 8, 10).\n\n**Immediate compliance or behaviour changes**\n\n- Taxpayers and advisers must check whether actions taken under Commonwealth-applied mirror laws satisfy State requirements (s 7B) and whether combined liabilities are being preserved (s 7A).\n- State authorities must put in place information flows with Commonwealth counterparts so the Commissioner of State Revenue can rely on actions taken under corresponding applied laws (s 7B(d))."}},"importantCases":[],"_links":{"self":"/api/acts/vic-commonwealth-places-mirror-taxes-administration-act-1999","history":"/api/acts/vic-commonwealth-places-mirror-taxes-administration-act-1999/history","analysis":"/api/acts/vic-commonwealth-places-mirror-taxes-administration-act-1999/analysis","conflicts":"/api/acts/vic-commonwealth-places-mirror-taxes-administration-act-1999/conflicts","importantCases":"/api/acts/vic-commonwealth-places-mirror-taxes-administration-act-1999/important-cases","documents":"/api/acts/vic-commonwealth-places-mirror-taxes-administration-act-1999/documents"}}
