HMRC Error code 6010

• HMRC error 6010 occurs: Your submission is not in the correct format. This
  means that it is too early to submit the P11D(b) return for this Employer - You will need to wait until after 5th April before you can submit this.

  (If after 5th April, check that you are only trying to submit for the previous tax year & that you are in the correct tax year on BrightPay - check the tax year at the top left of your screen).

If you have moved over to BrightPay mid-year, check the mid-year totals are correct and that the figures entered are not causing the negative YTD values that HMRC are rejecting.

If your FPS or EPS submission to HMRC is unsuccessful, check your PAYE credentials, RTI settings, ensure you are not submitting outside the valid period, and review any HMRC error codes for further troubleshooting. For common errors, see Common HMRC Error Messages or contact support.

If you receive error 4065 — Invalid content at AtLELYTD — this occurs when an employer has been set up as a mid-year start and the value entered in the At LEL field within the employee's mid-year totals is too high or in an incorrect format.

To resolve:

1. Go to the RTI tab and open the rejected FPS. Use Ctrl+F (Windows) or Cmd+F (Mac) to search for the value shown in the error message — this will help you identify which employee is causing the issue.
2. Once you have identified the employee, go to their record and open the Mid-Year Totals section.
3. Locate the National Insurance line and review the figure entered in the At LEL field.
4. Correct the figure, then re-open and re-finalise their payslip, then resubmit the FPS.
