You may consider, in a particular case, that you have grounds
for making a discovery decision based on both S20(1) (revision of
income tax liability) and S20(4) (fraud or neglect). If so, you may
be able to make a discovery decision up to five years after the end
of the year, rather than up to one year after the date on which the
income tax liability was revised. You should not, however, seek to
establish fraud or neglect purely so that you can extend the time
limit for making your discovery decision. Nor should you normally
delay making your discovery decision, unless there are particular
reasons for doing so.
Where both
you should normally make your discovery decision before the earlier of the two time limits. This will avoid the potential for the claimant(s) to dispute your right to make a discovery decision on the grounds of fraud or neglect.
Mark is a self employed DJ, who claimed and was awarded tax
credits for 2003/2004. He files his 2004 SA return on 28 January
2005. No SA enquiry is made into the 2004 return, so the NTC
enquiry window for 2003/4 closes on 31 January 2006.
Mark’s 2005 SA return is subsequently taken up for
enquiry on 27 July 2006 and, as part of that enquiry, an SA
discovery assessment is made on 15 January 2007 to increase his
self employed income for 2003/2004.
As a consequence of the SA discovery assessment, you need to
make a discovery decision for 2003/2004. If your reason for making
the discovery decision is solely because Mark’s income tax
liability for that year has been revised, you will have one year
from the date of the revision to make your decision. As the
revision (the SA discovery assessment) was made on 15 January 2007,
you would have to make the NTC discovery decision by 15 January
2008.
If you had established fraud or neglect on Mark’s part,
you would have until 5 April 2009 to make the discovery decision
– though in practice, you should still normally make it by
the earlier date of 15 January 2008. In this example, it is likely
that you would be able to establish fraud or neglect, as the making
of the SA discovery assessment as part of an SA enquiry is likely
to indicate that the taxpayer has committed an offence.
