If you wish to dispute the
assessment, you must lodge a notice of objection in writing
stating precisely the grounds of objection
within one month after the issue date of the notice of assessment.
If the tax charged is excessive by reason
of errors or omissions in the return already submitted, you
may apply for revision of assessment within 6 years after
the end of the relevant year of assessment or within 6 months
after the date on which the relevant notice of assessment
was served, whichever is the later. State details of the error
or omission and submit sufficient evidence to substantiate
If the claim is accepted, revised notice
of assessment will be issued and the relevant tax will be
refunded (if the tax has been paid) or discharged (if the
tax has not yet been paid).
