STATUTORY RULES 1987 No. 120

ISSUED BY THE AUTHORITY OF THE TREASURER

INCOME TAX REGULATIONS (AMENDMENT)

The purpose of the amending regulations is to ensure that instalments of company tax in respect of income of the 1986-87 year, and notified to companies and payable by them after 1 July 1987, are calculated having regard to the new 49 per cent company rate of tax that is to apply in calculating the tax payable by companies On incomes of the 1986-87 year. The company rate of tax is declared by the Income Tax Rates Act 1986. That Act was amended by the Income Tax Rates Amendment Act 1987 to increase the company rate of tax from 46 per cent to 49 per cent in respect of the incomes of companies for the 1986-87 and subsequent years.

Under the provisions of Division 1A of Part VI of the Income Tax Assessment Act 1936 (the Assessment Act) companies may be required to pay during a financial year three instalments of company tax in respect of the income of the preceding financial year, “the income year”, or the accounting period


adopted in lieu of that year. The balance of the tax in respect of the income year is payable following the receipt of a notice of assessment. The instalments generally are equal to one quarter of the company’s notional tax - an amount that is the income tax assessed in respect of the company’s taxable income (other than any capital gain) of the year preceding the income year. For example, the notional tax of a company in respect of income of the 1986-87 income year (tax on which will be payable at the new 49 per cent rate) would be the tax payable on the company’s 1985-86 taxable income - that is, tax calculated at the rate of 46 per cent.

Subsection 221AD(2) of the Assessment Act provides that, where the rate of income tax payable by companies for an income year is changed, the notional tax amount used for the purposes of calculating tax instalments may be varied by regulation to reflect the new rate of tax.

The amending regulations vary the notional tax of most companies and prescribed unit trusts (trusts that are taxed as companies) in respect of the 1986-87 income year. The notional tax will not be varied for registered organizations or for non-profit companies, not being registered organizations, whose income tax assessed in respect of the 1985-86 income year is less than $1753.98.

Notes on each of the amending regulations are set out below:


Principal Regulations

Regulation 1 facilitates reference to the Income Tax Regulations, which are referred to as the “Principal Regulations” in the amending regulations.

Heading to Division 3 of Part VI

By regulation 2, the existing heading to Division 3 of Part VI of the Principal Regulations is to be replaced with a new heading - “Division 3 - Notional Tax and Provisional Tax”.

Variation of amount of notional tax of companies

Regulation 3 will insert new regulation 54ZA into the Principal Regulations.

Subregulation (1) of regulation 54ZA sets out, as authorised by subsection 221AD(2) of the Assessment Act, the basis by which the amount that would otherwise be the notional tax of a company for the 1986-87 year of income is to be varied to ascertain the amount that is to be the notional tax for that year of income.


By subregulation (1), the notional tax for the 1986-87 year of income is to be the amount otherwise applying in accordance with subsection 221AD(1) multiplied by the factor 49/46. That is, the income tax assessed in respect of the taxable income of a company for the 1985-86 year of income multiplied by 49/46.

Subsection 221AD(2) of the Assessment Act stipulates that the notional tax of a company, calculated by a provision made by regulations, is to apply on and after the date that is prescribed. By subregulation (2) the notional tax of the company for the 1986-87 income year, as a consequence of the operation of subregulation (1), is to apply in respect of instalments of tax notified on or after 1 July 1987.

Subregulation (3) of regulation 54ZA specifies that for the purposes of regulation 54ZA, the term “company” includes a corporate unit trust and a public trading trust (terms used in the Income Tax Rates Act 1986 and the Assessment Act), but does not include -

a registered organization, that is, a trade union and any other registered employee organization, and a friendly society (other than a friendly society dispensary) that is not carried on for the purpose of profit or gain to individual members (paragraph (a)); or


a non-profit company, not being a registered organization, where the notional tax that would otherwise apply in respect of the 1986-87 income year does not exceed $1753.98 (paragraph (b)).

The exclusion of registered organizations by paragraph (3)(a) applies because there has been no increase in the rate of tax, 20 per cent, payable by such organizations. The exclusion by paragraph (3)(b) of non-profit companies operates to ensure that such a company’s notional tax will not be varied unless, having regard to the tax assessed on the company’s 1985-86 taxable income, it is likely that the company would be required to pay tax at the 49 per cent rate on its 1986-87 taxable income - that is, where its 1986-87 taxable income exceeds $3,813.

Subregulation (4) of regulation 54ZA is a drafting measure to ensure that a reference to the taxable income of a company includes a reference, where appropriate, to the net income of a corporate unit trust or the net income of a public trading trust.

Overview

The Income Tax Regulations (Amendment) Statutory Rules 1987 No. 120 were enacted to address the need for adjusting company tax instalments for the 1986-87 income year following the increase in the company tax rate from 46% to 49%. This change was declared in the Income Tax Rates Amendment Act 1987. The regulations were issued under the authority of the Treasurer and aim to ensure that tax instalments for the specified income year are calculated with the new tax rate in mind. The Income Tax Assessment Act 1936, which governs the payment of tax instalments by companies, allows for adjustments to the notional tax through regulation when the tax rate changes. The regulations vary the notional tax for most companies and prescribed unit trusts for the 1986-87 income year to reflect the new tax rate, while excluding registered organisations and certain non-profit companies from this adjustment. These amending regulations were introduced to provide clarity and consistency in tax calculations for companies, ensuring that the new tax rate is appropriately reflected in their tax instalments for the 1986-87 income year. By inserting new regulation 54ZA into the Principal Regulations, the amendments specify the method for calculating the varied notional tax and ensure that the changes apply to the correct entities, thereby facilitating a smooth transition to the new tax rate and maintaining compliance with tax obligations.

Scope and Application

The Income Tax Regulations (Amendment) Statutory Rules 1987 No. 120, issued by the authority of the Treasurer, specifically target companies and prescribed unit trusts to modify their notional tax amounts for the 1986-87 income year to reflect the new 49 per cent company tax rate, as declared by the Income Tax Rates Act 1986 and amended by the Income Tax Rates Amendment Act 1987. This adjustment applies to most companies and prescribed unit trusts, except for registered organizations, which include trade unions, registered employee organisations, and friendly societies not carried on for profit or gain to individual members, as well as non-profit companies, not being registered organizations, with a notional tax not exceeding $1753.98 for the 1986-87 income year. These amendments are designed to ensure compliance with the new tax rate by adjusting the basis for calculating tax instalments due from companies on or after 1 July 1987. The regulations extend to the Commonwealth level and are enforced through the Income Tax Assessment Act 1936, which allows for the variation of notional tax amounts by regulation when the rate of tax changes.

Key Provisions

The Income Tax Regulations (Amendment) Statutory Rules 1987 No. 120 amend the existing income tax regulations to adjust the calculation of company tax instalments for the 1986-87 income year, in light of the new company tax rate of 49% introduced by the Income Tax Rates Amendment Act 1987 (section 2). Under the Income Tax Assessment Act 1936 (the Assessment Act), companies are generally required to pay three instalments of company tax during a financial year based on their income from the preceding year (subsection 221AD(1)). The amendment ensures that for the 1986-87 income year, the notional tax, which forms the basis of these instalments, is recalculated using the new tax rate (subsection 221AD(2)). The amending regulations impose specific obligations on companies and prescribed unit trusts to recalculate their notional tax for the 1986-87 income year by multiplying their 1985-86 taxable income by the factor 49/46 (regulation 54ZA(1)). This adjustment applies to tax instalments notified on or after 1 July 1987 (regulation 54ZA(2)). Notably, the regulation excludes registered organizations and non-profit companies with a notional tax of $1753.98 or less, as they are not subject to the new tax rate (regulation 54ZA(3)). Additionally, the regulation ensures that references to taxable income include the net income of corporate unit trusts and public trading trusts where appropriate (regulation 54ZA(4)). Failure to comply with the new tax calculation requirements could result in inaccuracies in the instalment payments, potentially leading to underpayment or overpayment of tax. While the amending regulations do not explicitly outline specific penalties for non-compliance, general tax law provisions apply. For instance, under the Assessment Act, failure to pay tax on time or underpay can result in penalties and interest on the unpaid amount (section 186). Additionally, serious or repeated non-compliance might lead to more severe consequences, including fines and, in extreme cases, criminal charges for tax evasion or fraud.
