We’d like to remind you of how errors occur in MDC submissions. There are several reasons why you may receive an email advising of necessary corrections.

Please familiarise yourself with the following common errors:

• Missing fields such as name, dob, NINO, F/T, P/T earnings
• Incorrect file names
• Excessive part-time salary
• Full-time salary recorded as part-time annual salary
• Personal data doesn’t match with what we hold on our system
• Incorrect LA/Establishment number
• Establishment isn’t linked to the payroll provider or MAT who submit the data
• Incorrectly recorded concurrent service
• Missing salary data, e.g, full-time annual salary
• Incorrect dates.

If you’re still unsure, we’ve a guidance document (PDF, 626 KB) (This link opens in a new window) and further MDC resources specifically designed to help you.
