Can I submit last month's overdue EPS this month? It gives me error every time I try to submit it.

Hello, dee-gorgevic. 

Before we begin, could you please tell me which payroll option you use in your QuickBooks account, is it Core, Standard, or Advanced Payroll? Can you also specify the error message you received when attempting to submit?

The EPS (Employer Payment Submission) can only be submitted between the 6th and 19th of each month. If you miss the submission deadline, you may submit the EPS the following month. To submit EPS to HMRC, we can follow these steps: 

1. Go to Taxes, then select Payroll Tax.
2. In the Payroll Tax Center, you'll see that if you have an EPS filing that needs to be sent, it is listed under Due Now with a status of Overdue and the date that it was supposed to be sent.
3. Click the EPS and view the details.
4. Select Submit.

If there's anything specific you'd like help with regarding the submission process, just let me know. I’m committed to making this as smooth as possible for you!
