Part 6Assessments
108BExtension of time bars
The application of a time bar that is referred to in subsection (3) may be delayed for a taxpayer by a waiver—
- for 12 months from the time at which the time bar would otherwise apply if—
- the taxpayer and the Commissioner agree to the waiver; and
- their agreement is recorded in a document; and
- the taxpayer and the Commissioner agree to the waiver; and
- for a further 6 months from the end of the 12-month period referred to in paragraph (a), by
notice given by the taxpayer. A waiver under subsection (1) does not affect the application of a time bar to an assessment of the taxpayer by the Commissioner on a ground that was not identified and known to the taxpayer and the Commissioner before the time at which the time bar would have applied but for subsection (1).
An agreement under subsection (1)(a) must be in the prescribed form and must be signed and delivered to the Commissioner before the expiry of the relevant 4-year period.
A notice under subsection (1)(b) must be given to the Commissioner before the expiry of the 12-month period referred to in subsection (1)(a).
Subsection (1) applies to—
- the time bar occurring under section 25 of the Income Tax Act 1976 after the period of 4 years from the end of the year in which the notice of original assessment was issued; and
- the time bar occurring under section 107A after the period of 4 years from the end of the year in which the notice of original assessment was issued; and
- the time bar occurring under section 108 (as that section applied before it was amended by section 29 of the Tax Administration Amendment Act (No 2) 1996) after the period of 4 years from the end of the year in which the notice of original assessment was issued; and
- the time bar occurring under section 108(1), (1B), and (1C) (as amended by section 29 of the Tax Administration Amendment Act (No 2) 1996) after the period of 4 years from the end of the tax year in which the taxpayer provides a return of income; and
- the time bar occurring under the former section 31 of the Goods and Services Tax Act 1985 (as that section applied on 30 September 1996) after the period of 4 years from the end of the month in which the GST return was provided or, as the case may be, the assessment made; and
- the time bar occurring under section 108A(1) after the period of 4 years from the end of the GST return period in which the GST tax return was provided; and
- the time bar occurring under section 108AB after the period of 4 years from the date on which the taxpayer provided the employment income information.
