If you don't submit your EPS by the deadline for a tax month, you can submit an EPS when you process the next period. Each EPS includes year to date values, so HMRC receive the correct totals for the tax year to date.
NOTE: If you forget to submit your EPS, you can add the values to the next submission because it's a cumulative submission.
TIP:Tax months run from the 6th of one month to the 5th of another, for example 6 April to 5 May.
Check the P32 - Employer Payment Record report
Click Reports then click Period End.
Click Form - P32 Employer Payment Record then click Preview.

There are different scenarios where you may need to submit the EPS. You may need to adjust your payment to HMRC because you have statutory payments to recover and any related NI compensation. You may also need to let HMRC know that there's no payment due for this month, previous months or future months.
