• Uniform capital allowance system (UCA)

    From 1 July 2001, there are new rules for working out deductions for your depreciating assets, such as your plant and equipment. These new rules are part of the uniform capital allowance system or UCA.

    The UCA also introduced some new deductions for business related capital expenditure that was previously not deductible. The expenditure is written off over five years. The deduction is only available for amounts incurred from 1 July 2001.

    If your business earns income that is not assessable, such as exempt income, your deduction is reduced.

    Costs in establishing your business structure

    The UCA allows a deduction over five years for capital expenditure to establish your business structure. Your business structure means the entity, such as a company or trust that carries on your business and holds the business assets. However, if you are an individual taxpayer, the non-commercial loss rules may defer your deductions for pre and post-business expenditure.


    Examples of business structure costs that may be deductible are the expenses of incorporating a company, creating a trust or forming a partnership. The deduction is not available for the cost of acquiring a franchise or goodwill, or in relation to leases.

    Other types of capital expenditure that are now deductible under the UCA include the costs to stop carrying on your business and to convert your business structure to a different structure - for example, if you are a sole trader and decide to start carrying on your business through a company. These costs may also be written off over five years. The relevant expenditure is deductible to the extent that the sole trader business was, and the company business is proposed to be, carried on for a taxable purpose.
