Default interest

May 2010

This notice cancels and replaces Notice 700/43 (June 2009).

1 Introduction

1.1 What is this notice about?

This notice explains how default interest works and when it is applied. It also gives advice about what to do if you think you have been charged too much interest.

1.2 What is default interest?

Main narrative treatment—V5.361–V5.365.
