A company has one employee paid fortnightly well under PAYE/NIC limit. 2 weeks ago or so the director was incredibly busy, coronavirus rules to blame, and RTI filing was overlooked. The gap in submissions was discovered after subsequent filing. Now Basic PAYE Tools do not permit filing for the previous period saying ‘The date you have entered is not valid. The payment date must be after the date of the last payment to this employee. Please amend your entry.’
Cannot find instructions on what to do anywhere. Presumably many of you use commercial software – does it have the same problem?
