I use Payroll Manager. For one of the clients there was SMP in month 1 and an EPS was filed. At this point the Employer Allowance box wasn't ticked as Client was still deciding which business would claim it (I only do payroll for this Client and don't do anything for the other company). Employer Allowance box then ticked but this didn't generate an EPS to file in month 2 (then no SMP either).
Looking back on the EPS for month 1 it shows the Employment Allowance box as ticked even though it wasn't submitted with the box ticked. In fact if I untick the box in the Employer Details box it changes it on the month 1 EPS - I would have expected that once something was submitted it would be locked.
My choices seem to be to temporarily allow re-submissions and re-submit the month 1 EPS or use the HMRC basic toolkit and file a month 2 EPS. HMRC said if your software won't allow it do via the toolkit but I don't want to do it as month 3 and have HMRC claim that the month 2 payment was late (month 1 was paid in full). I don't know if I am opening a can of worms by re-submitting the month 1 EPS.
Any advice please?
