What Is an RTI Submission in Sage Payroll?

Real Time Information (RTI) is the process employers use to report employee payroll information to HM Revenue & Customs (HMRC). Sage Payroll allows employers to prepare and submit payroll information electronically after completing a pay run.

Depending on the payroll process, an employer may need to submit a Full Payment Submission (FPS), Employer Payment Summary (EPS), or another required report. Sage checks payroll information before sending the submission.

When an RTI submission fails, Sage may display an error message instead of confirming the submission. The exact cause can vary, so checking the message and submission details is important before attempting the process again.

Why Is Sage Payroll RTI Submission Failing?

Several issues can prevent Sage Payroll from successfully submitting RTI information.

1. Incorrect Employee Information

Employee records must contain accurate information before payroll data is submitted. Missing or incorrectly entered details can cause validation failures.

Check information such as:

  • Employee name and address
  • National Insurance number
  • Date of birth
  • Employment status
  • Tax code
  • National Insurance category
  • Payroll ID
  • Starter or leaver information

A small discrepancy can sometimes prevent the submission from being accepted.

2. Incorrect Employer or PAYE Details

Your employer information also needs to match the details registered with HMRC. Review the PAYE reference, Accounts Office reference, employer name, and other payroll registration details.

If the employer information in Sage does not correspond with HMRC records, the submission may be rejected.

3. Payroll Data Has Not Been Finalised Correctly

RTI is generated from payroll information. If the pay run contains incomplete or incorrect entries, the resulting submission can contain invalid data.

Before submitting, review the payroll calculations and make sure the relevant pay period has been completed properly.

4. Internet or Connectivity Problems

Sage Payroll requires an internet connection to communicate with online services. A temporary network problem can interrupt the submission process.

If the connection is unstable, close unnecessary applications that use significant bandwidth and try the submission again after confirming that your internet connection is working normally.

5. HMRC Service Availability

Sometimes the problem is not caused by Sage at all. HMRC services can experience maintenance periods or temporary technical problems.

If everything in the payroll records appears correct but submissions repeatedly fail, checking the status of the relevant HMRC service can help determine whether the issue is external.

6. Outdated Sage Payroll Software

Older versions of Sage Payroll may not contain the latest changes required for payroll processing or online submissions.

Check whether a Sage Payroll update is available and install applicable updates before retrying the RTI submission.

How Can You Fix a Failed Sage Payroll RTI Submission?

Start with the error message displayed by Sage. It can provide a useful clue about whether the problem relates to employee data, employer information, submission details, or communication with HMRC.

Step 1: Check the Submission Status

Open the relevant payroll area and review the RTI submission history. Determine whether the submission is marked as failed, rejected, pending, or incomplete.

Do not immediately create another submission without understanding what happened to the previous one.

Step 2: Review Employee Records

Check the employee affected by the submission. Compare their payroll details with the information you have on file.

Pay particular attention to National Insurance numbers, tax codes, dates, employment status, and starter or leaver information.

Step 3: Verify Employer Settings

Review the employer's PAYE and HMRC-related details in Sage Payroll. Correct any obvious discrepancies before generating another submission.

Step 4: Check the Payroll Period

Confirm that the correct pay period and payment date have been selected. An incorrect payment date can affect the RTI information being reported.

Also verify that the payroll has been processed for the intended period.

Step 5: Update Sage Payroll

If the software is not current, install the appropriate update. Restart Sage after updating and review the payroll records again.

Keeping payroll software current can also help avoid compatibility and submission problems.

Step 6: Retry the Submission

Once the underlying issue has been corrected, follow the normal Sage RTI submission procedure. Check the confirmation message after sending the information.

If the submission is accepted, retain the confirmation details for your payroll records.

What Should You Do If Sage RTI Is Rejected by HMRC?

A rejection is different from a temporary submission failure. HMRC may provide a reason explaining why the information was not accepted.

Read the rejection message carefully and identify the employee, payroll period, or field mentioned in the response. Correct the relevant information in Sage and follow the appropriate resubmission procedure.

Avoid repeatedly submitting unchanged information because the same error may simply occur again.

How Can You Prevent Future RTI Submission Problems?

A few routine checks can reduce payroll submission issues:

  • Keep Sage Payroll updated.
  • Review employee records regularly.
  • Verify PAYE details.
  • Check tax codes and National Insurance categories.
  • Confirm payment dates before submitting.
  • Keep records of successful RTI submissions.
  • Review HMRC rejection messages carefully.
  • Maintain a reliable internet connection during submission.
  • Back up payroll data according to your normal business procedure.

Regular checks are especially useful before payroll deadlines because they give you time to correct errors instead of discovering them immediately before an RTI deadline.
