South Australian Consolidated Acts14—Form of assessment and service on taxpayer
(1) The Commissioner
may make an assessment only by a written notice that is—
(a)
expressed to be an assessment of liability to the tax; and
(b) in a
form approved by the Commissioner.
(2) The assessment
must be served on the taxpayer concerned.
(3) However, neither
the validity of an assessment nor the recovery of an amount to which it
relates is affected by failure to serve the assessment on the taxpayer.
(4) The receipt by the
Commissioner of a return or an amount as payment of a tax does not constitute
the making of an assessment of tax liability.
