Commentary on Sections Part 6 - Interest Sections 157-160 – Interest on amounts payable to WRA
187.Section 157 provides that interest is payable by a person on devolved tax and related penalties that are not paid before the late payment interest start date. Interest is incurred from the late payment interest start date until the tax or penalty is paid. Subsection (3) states that in a normal case the late payment interest start date is the day after the day the amount of tax or penalty becomes payable.
188.Section 158 provides that late payment interest is not payable on late payment interest. It also makes clear that when an amount of tax or penalty that is payable is set off against an amount to be repaid to the taxpayer by WRA, the date of that set-off is counted as the date of payment for the purposes of working out when interests stops accruing.
189.Section 159 establishes the late payment interest start date where an amount of devolved tax becomes payable in circumstances where an assessment (including a self-assessment or WRA assessment or a determination) has been amended or corrected.
190.Section 160 establishes the late payment interest start date in circumstances where a person dies before an amount of devolved tax or related penalty becomes payable and the executor or administrator is not able to pay the amount until probate or letters of administration or another equivalent document is resolved. Late payment interest will start from the later of the standard late payment interest start date, or 30 days after the grant of probate or letters of administration.
