The financial arrangement rules can apply to amounts that might otherwise be treated as capital amounts. They can require income and expenses to be spread over the term of the arrangement.

At the end of the arrangement there is usually a wash-up calculation called a base price adjustment (BPA). This calculation is to make sure the right amount of income will be reported.

There are several methods for spreading income and expenses. Which one you can use depends on the circumstances.

You can read more about foreign arrangement rules in our Foreign income guide - IR1247 in the compliance focus for individuals' section.
