Market Valuation Required
Where a taxpayer’s main residence was first acquired after 19 September 1985, and first used to produce income after 7.30pm on 20 August 1996, the taxpayer is generally deemed to have acquired the property, for CGT purposes, at the market value at the time it was first used to produce income. This means for main residences converted to income producing after 20 August 1996, a capital gain or loss is calculated on the difference between the market value at the date of change of use and the net sale price when subsequently sold.
A market value must be obtained at the date the home first became available to produce income if it:
-
was first used as a main residence and
-
was first used to produce income after 20 August 1996 and
-
was rented out for more than 6 years or the taxpayer elects another home as their main residence for tax purposes
The market value on that date is used as the cost base for CGT purposes, rather than the original cost. This will usually reduce the CGT payable.
Double Dip! Even though the capital gain is not determined by reference to the original cost, the taxable capital gain/loss will still be determined by apportioning the gain/loss calculated using the market value as the cost base between the rental period (taxable) and the actual and deemed residence period (tax free).
Market Valuation Not Required
However, the market value at the date of change of use is not relevant if:
-
the home was first used to produce income before 21 August 1996 or
-
the home was first used to produce income before it became the taxpayer’s main residence or
-
the property was purchased pre-20 September 1985
Unless the property was acquired pre-20 September 1985, you will be required to calculate the capital gain over the whole period you have owned it and then apportion the gain between the number of days it was covered by your main residence exemption and the number of days it was not.
The costs, including 3rd element costs of ownership (see container above and Section 110-25(4) of the Income Tax Act) that are associated with the period you lived in it, count proportionally towards reducing CGT on the period when it was rented and so exposed to CGT, if you have not already previously claimed them as a tax deduction
The six-year absence rule
Where a taxpayer’s main residence is acquired after 19 September 1985, the taxpayer can elect to continue to treat the home as their main residence for a maximum of six consecutive years while it is being rented out, provided that they do not elect to treat any other property as their main residence during this period. Each time they re-occupy the home as their only principal residence the six-year concession starts again.
If your vacated home is not used to produce income, you can elect to treat it as your only main residence for an unlimited period.
