Income Tax Assessment Act 1997
The amount of your tax offset is based on the amount of foreign income tax you have paid.
However, there is a limit on the maximum amount of your offset. The limit is the greater of $1,000 and an amount worked out under this Subdivision. This amount is based on a comparison between your tax liability and the tax liability you would have if certain foreign-taxed and foreign-sourced income and related deductions were disregarded.
You may choose to use the limit of $1,000 and not work out this amount.
There is an increase in the limit to ensure foreign income tax paid on some amounts that are not taxed always forms part of the offset.
