(i) Notices of assessment
13 On 11 September 2001, the DCT issued a Notice of Assessment to the defendant for income tax and additional tax for 1999 due and payable on 16 October 2001. The taxable income was calculated at $500,000. This Notice of Assessment was subject to challenge by the defendant in the Federal Court of Australia. On 22 June 2004, the DCT issued a Notice of Amended Assessment for the year ending 30 June 1999. The amended taxable income was $80,291. The date due for payment was expressed to be "as previously advised".
14 On 14 December 2004, Mr Justice Hill made the following orders:
"1. The objection decision be set aside and in lieu thereof the applicant's objection be allowed in part so that the taxable income and tax payable thereon in respect of the relevant year of income be in accordance with the amended assessment issued to the applicant on 22 June 2004.
2. The respondent pay the applicant's costs."
15 Hence, the taxable income and tax payable is in accordance with the amended assessment issued on 22 June 2004. Justice Hill did not decide that the date which the tax was payable was incorrect. It is true to say that his Honour made no finding on this issue.
16 The defendant says the 1999 assessment was the subject of a decision of Justice Hill of the Federal Court of Australia on 14 December 2004 and submitted that because of the orders made by Justice Hill, that assessment is, as described at the time, "dead in the water".
17 The defendant submitted that there are material differences between the 1999 assessments issued on 11 September 2001 and the amended assessment issued on 22 June 2004. At paragraph 8 of the FASC an amount of $58,344.56 in relation to interest for late payment calculated from 16 October 2001 is claimed. The defendant says that this amount cannot be claimed as it is calculated from the due date of the original assessment. According to the defendant, the date from which interest can be claimed is from 21 days after 22 June 2004 ie, 13 July 2004.
18 The DCT has pleaded that by reason of the failure to pay income tax by the due date, the defendant became liable to pay the general interest charge (GIC) pursuant to s 204 of the ITAA36 and Part IIA of the TAA. The GIC was calculated on a compounding daily basis from the end of each of the respective due dates until 8 January 2008 by multiplying the GIC rate for each day (GIC daily rate) by the sum of so much of the following amounts as remained unpaid: a) the income tax for the year ending 30 June 1999; and b) the GIC from previous days (paras [6]-[7] FASC).
19 Section 163B of the ITAA36 provides that if a person does not lodge a return by the due date for lodgement and an assessment is made of the income tax payable by the person for the year of income, the person is liable to pay additional tax, being GIC on an amount calculated pursuant to s 163B(2) for the period starting on the day by which the return was to be furnished and ending on the day before the return is furnished or the day the Commissioner made the assessment, whichever is earlier.
20 Section 204 of the ITAA36 relevantly reads:
