Income Tax Assessment Amendment Regulations 2005 (No. 1)

Section 9091 of the Income Tax Assessment Act 1997 (the Act) provides that the Governor-General may make regulations prescribing matters required or permitted by the Act to be prescribed, or necessary or convenient to be prescribed for carrying out or giving effect to the Act.

The purpose of the amending regulations is to insert the cents per kilometre rates for calculating deductions for car expenses for the 2004-2005 income year in Part 2 of Schedule 1 of the Income Tax Assessment Regulations 1997 (the Principal Regulations).

Division 28 of the Act outlines the four methods for calculating deductions for car expenses. To calculate the deduction under the ‘cents per kilometre’ method (section 2825), the number of business kilometres the car travelled during the year of income is multiplied by a specified number of cents. The cents per kilometre rate is determined in relation to the car’s engine capacity and is prescribed in the Principal Regulations. This method can be used for the first 5,000 business kilometres only. If a taxpayer wishes to claim more than 5,000 business kilometres, he or she must use one of the other methods outlined in Division 28 of the Act.

The number of cents used in the ‘cents per kilometre’ method are set out in Part 2 of Schedule 1 to the Principal Regulations. The rates are revised each year and the ones currently prescribed apply only up to and including the 2003-2004 financial year. Since the 19861987 financial year, the rates in the Regulations have followed the rates of motor vehicle allowance for the Commonwealth Public Service set out by the Department of Employment and Workplace Relations.

The rates for the 2004-2005 income year are as follows:

 

Description

Engine capacity of car not powered by a rotary engine (cubic centimetres)

Engine capacity of car powered by a rotary engine (cubic centimetres)

Rate per kilometre (cents)

Small car

Not exceeding 1600cc

Not exceeding 800cc

52

Medium car

Exceeding 1600cc but not exceeding 2600cc

Exceeding 800cc but not exceeding 1300cc

62

Large car

Exceeding 2600cc

Exceeding 1300cc

63

 

The Regulations are also relevant for the purposes of the Fringe Benefits Tax Assessment Act 1986 (FBTAA). The definition of ‘basic car rate’ in subsection 136(1) of the FBTAA provides that the rate is the same as that prescribed for the purposes of section 2825 of the Act. ‘Basic car rate’ is used in the calculation of the taxable values of a number of fringe benefits.

 

The Regulations commenced on the day after they were registered on the Federal Register of Legislative Instruments.

Overview

The Income Tax Assessment Amendment Regulations 2005 (No. 1) were enacted to address the need to update the 'cents per kilometre' rates for calculating deductions for car expenses under the Income Tax Assessment Act 1997. These regulations were issued by the Minister for Revenue and Assistant Treasurer under the authority of the Governor-General, in accordance with section 909-1 of the Act. The primary objective of these amendments is to provide the necessary rates for the 2004-2005 income year, ensuring that taxpayers have the correct figures for claiming deductions under the 'cents per kilometre' method. These rates are crucial for the calculation of business kilometres travelled by a car and are linked to the car’s engine capacity, with different rates applied to small, medium, and large cars, as well as those powered by rotary engines. The rates prescribed in these regulations are intended to align with the motor vehicle allowance rates set by the Commonwealth Public Service and are also relevant for fringe benefits tax assessments under the Fringe Benefits Tax Assessment Act 1986.

Scope and Application

The Income Tax Assessment Amendment Regulations 2005 (No. 1) concern the calculation of deductions for car expenses under the Income Tax Assessment Act 1997. These regulations apply to individuals and entities who use the 'cents per kilometre' method to calculate their car expense deductions for the 2004-2005 income year. This method involves multiplying the number of business kilometres driven by a specified number of cents, determined by the car's engine capacity. The rates prescribed in these regulations apply to cars with engine capacities up to and including 2600 cubic centimetres and are also relevant for calculating taxable values of fringe benefits under the Fringe Benefits Tax Assessment Act 1986. The rates are categorised into small, medium, and large cars, with differing rates for cars powered by rotary engines. The Regulations are necessary to provide the specific rates for the mentioned income year and have a direct impact on taxpayers' ability to claim deductions. The rates are set in line with those used for the Commonwealth Public Service, ensuring consistency in tax treatment.

Key Provisions

The Income Tax Assessment Amendment Regulations 2005 (No. 1) establish the rates for calculating deductions for car expenses under the ‘cents per kilometre’ method for the 2004-2005 income year (section 909-1). These rates are prescribed in Part 2 of Schedule 1 of the Income Tax Assessment Regulations 1997 (Principal Regulations) and are based on the engine capacity of the car. The method allows taxpayers to claim deductions for the first 5,000 business kilometres travelled during the income year by multiplying the number of kilometres by the specified rate in cents. This method applies to both non-rotary and rotary engine cars, with different rates for small, medium, and large cars. Taxpayers who use the ‘cents per kilometre’ method must adhere to the rates set out in the regulations for the relevant financial year. The rates for the 2004-2005 income year are 52 cents per kilometre for small cars, 62 cents for medium cars, and 63 cents for large cars, with specific definitions of engine capacity for both non-rotary and rotary engines. The rates are consistent with those used by the Commonwealth Public Service since the 1986-1987 financial year, as set out by the Department of Employment and Workplace Relations. This ensures uniformity and fairness in the application of these rates across different sectors. The Regulations impose several obligations on taxpayers who claim car expenses as deductions. They must accurately calculate the number of business kilometres travelled and apply the correct cents per kilometre rate based on their car’s engine capacity. Additionally, taxpayers must ensure that their claims comply with all other relevant provisions of the Income Tax Assessment Act 1997 and associated regulations. Failure to accurately calculate or document these expenses can lead to errors in tax returns and potential scrutiny from the Australian Taxation Office (ATO). Breaching the provisions of the Income Tax Assessment Act 1997 or the Income Tax Assessment Amendment Regulations 2005 (No. 1) can lead to various consequences. The Act outlines penalties for making false or misleading statements, failing to lodge tax returns, and understating taxable income. The penalties can include fines, interest on the unpaid tax, and in severe cases, criminal charges. The maximum penalties vary depending on the nature and extent of the breach, with potential fines reaching thousands of dollars and imprisonment for serious offences. The ATO has the authority to investigate and enforce compliance with these regulations, ensuring that taxpayers accurately report and pay the correct amount of tax.
