Regulation 6

When the notice of assessment in respect of the income accrued, derived or received by a self‑employed person in any relevant year is subsequently issued after the end of the relevant year, the amount of contributions payable by the person must be recomputed on the basis of the amount of income stated in that assessment.

Where a self‑employed person’s income in any relevant year is not stated in a notice of assessment because his or her income is not chargeable to tax, the amount of contributions payable for that year may be recomputed on the basis of the amount of income assessed by the Comptroller and stated in a notice of computation or contributions notice, as the case may be.

Where the notice of assessment in respect of income of a self‑employed person for any relevant year before 1 January 2018 is amended or varied on appeal or where a notice of additional assessment has been issued by the Comptroller, the amount of contributions payable by the person for that year must be recomputed by taking into account the amount of income which has been varied or added.

Paragraphs (1) and (2) do not apply to contributions payable by a self‑employed person for the relevant year beginning 1 January 2002 and any subsequent relevant year.
