When a tax return is filed it must be paid within a certain period. The latest payment date will be the earlier of:

  • The fifth working day after the submission date
  • The last working day which is, or precedes, the 44th calendar day after the end of the quarter to which the return relates

Late returns and payment of tax may incur interest (see RSTP4002) and liability to penalties (see RSTP3005 and RSTP3008).
