Section 682 | Assessments, adjustments and claims after the administration period

(1)This subsection applies if after the administration period ends it is apparent that a person is liable for income tax on estate income for any tax year who previously appeared not to be so liable or to be liable for tax on a lesser amount.

(2)If subsection (1) applies—

(a)the person may be assessed and taxed for the tax year, and

(b)any relief or additional relief to which the person may be entitled for the tax year is to be allowed if a claim is made.

(3)This subsection applies if after the administration period ends it is apparent that a person who previously appeared to be liable for income tax on estate income for any tax year is not so liable or is liable for tax on a lesser amount.

(4)If subsection (3) applies—

(a)all necessary adjustments and repayments of income tax for the tax year are to be made, and

(b)if the person has been allowed relief which exceeds the relief that could have been given by reference to the amount actually charged for the tax year, income tax is charged on the person for that year under this subsection on the excess.

(4A)The excess charged under subsection (4)(b) is treated as an amount of income for income tax purposes, except so far as it represents a tax reduction given effect at Step 6 of the calculation in section 23 of ITA 2007.^F1

(5)An assessment or adjustment made for the purposes of this Chapter or a claim made as a result of this Chapter may be made after the end of the period otherwise allowed if it is made on or before the third anniversary of the normal self-assessment filing date for the tax year in which the administration period ends.
