If a trustee is dissatisfied with an assessment, the trustee may object against that assessment, generally within four years of the deemed assessment date. However, a trustee’s right to object to an assessment ascertaining that there is no taxable income or no tax to pay on the taxable income is limited. The objection must be made in the approved form, lodged with the Commissioner in the prescribed period and state within it, fully and in detail the grounds that the trustee relies on.
