Income tax: what are the consequences if a taxpayer fails to respond to a notice to produce documentary evidence, issued under subsection 82KZA(2) the Income Tax Assessment Act 1936?

The failure of a taxpayer to respond to a notice under subsection 82KZA(2), will result in a deduction for the unsubstantiated expense being disallowed, and deemed to have never been allowable.

The failure to respond to the notice is not an offence.

Interest may be imposed under section 170AA.
