Section 171 — Income Tax Assessment Act 1936: Where no notice of assessment served

(1) Where a taxpayer has duly furnished to the Commissioner a return of income, or of profits or gains of a capital nature, and no notice of assessment in respect thereof has been served within 12 months thereafter, the taxpayer may in writing by registered post request the Commissioner to make an assessment. (2) If within 3 months after the receipt by the Commissioner of the request a notice of assessment is not served upon the taxpayer, any assessment issued thereafter in respect of that income, or of those profits or gains, shall be deemed to be an amended assessment, and for the purpose of determining whether such amended assessment may be made, the taxpayer shall be deemed to have been served on the last day of the 3 months with a notice of assessment in respect of which income tax was payable on that day.
