Sage Payroll RTI Submission Errors can prevent payroll information from being submitted correctly to HMRC, leaving employers unsure whether their Full Payment Submission (FPS) or Employer Payment Summary (EPS) has been received. If you are trying to resolve Sage Payroll RTI Submission Errors, reviewing employee information, payroll settings, Government Gateway credentials, and software updates is a good starting point. For users who need additional assistance while checking an RTI submission, Sage Payroll RTI Submission Errors +1 (844) 341-4437 may also be used as a reference for getting help with the issue. Understanding why an RTI submission fails can make troubleshooting faster and reduce the risk of repeated payroll reporting problems.

What Are Sage Payroll RTI Submission Errors?

Real Time Information (RTI) is the system used by employers to report payroll information to HMRC. Sage Payroll uses RTI submissions to send details such as employee payments, deductions, National Insurance information, tax, and other payroll data.

An RTI submission error generally occurs when Sage cannot successfully create, validate, authenticate, or transmit the payroll information. The error may appear while submitting an FPS, EPS, or another RTI-related report.

The important point is that an error message does not always mean the payroll itself is incorrect. Sometimes the problem is caused by outdated software, incorrect employer information, Government Gateway authentication, employee records, or communication problems.

Common Sage Payroll RTI Errors

Several types of problems can occur during an RTI submission. Some of the most common Sage Payroll RTI errors include:

• FPS submission failures
• EPS submission errors
• Government Gateway authentication failures
• Incorrect PAYE reference details
• Invalid employer information
• Employee data validation errors
• Missing National Insurance information
• Incorrect tax codes
• Submission rejected by HMRC
• Sage Payroll unable to connect to HMRC
• RTI submission stuck or not completing
• Duplicate or previously submitted payroll information

Identifying the exact error message is important because different RTI problems require different troubleshooting steps.

Sage Payroll FPS Submission Error: What to Check

A Full Payment Submission reports employee pay information to HMRC. If an FPS fails, first check whether all employees included in the payroll have complete and valid records.

Review employee names, addresses, dates of birth, National Insurance numbers, tax codes, payment information, and starter or leaver details. A small inconsistency in employee information can sometimes prevent successful validation.

You should also confirm that the payroll has been processed correctly before attempting another submission. Avoid repeatedly submitting the same FPS without checking the submission status, because this can create confusion about whether HMRC has already received the information.

Sage Payroll EPS Submission Error and Its Causes

An Employer Payment Summary is used to send specific information to HMRC that may not be included in an FPS. EPS submissions can be required for circumstances such as statutory payments, Employment Allowance information, or periods where no employees were paid.

If Sage Payroll reports an EPS error, check the relevant employer settings and the period being reported. Verify that the correct tax month has been selected and that the payroll data matches the reporting period.

It is also worth checking whether an EPS has already been submitted for that period. Understanding the submission history can prevent unnecessary duplicate submissions.

Sage Payroll Government Gateway Authentication Error

One frequent variation of Sage Payroll RTI Submission Errors involves Government Gateway authentication. Sage Payroll must use the correct employer credentials and PAYE information when communicating with HMRC.

Check the Government Gateway user ID and password associated with the payroll submission. Also verify the employer PAYE reference and Accounts Office reference.

If credentials were recently changed, update the information within Sage Payroll before attempting another submission. Make sure that the credentials belong to the employer account being used for the RTI submission.

Sage Payroll RTI Validation Errors

Validation errors usually indicate that information within the payroll does not meet the requirements for an RTI submission.

Start by reading the complete error message rather than focusing only on the error number. Look for references to a specific employee, tax code, National Insurance category, date, or payroll field.

Correct the information in the employee or employer record and then run the appropriate payroll validation checks again. Keeping employee records accurate throughout the tax year can help prevent repeated validation failures.

Sage Payroll RTI Unable to Connect to HMRC

Sometimes Sage Payroll may be unable to communicate with HMRC even when the payroll information is correct. Network connectivity, temporary service interruptions, security settings, or software configuration can contribute to this type of problem.

Check that the computer has a stable internet connection and that Sage Payroll is operating normally. If the issue affects multiple submissions, check whether the problem is related to the Sage installation or the external HMRC service.

Avoid assuming that a connection error means payroll data needs to be changed. First determine whether the failure occurred during data validation or during transmission.

How to Fix Sage Payroll RTI Submission Errors

A systematic troubleshooting process is usually more effective than repeatedly attempting the submission.

1. Read the Complete Error Message

Record the exact error wording and any reference number displayed by Sage Payroll. This can help identify whether the issue involves employee data, employer information, authentication, or transmission.

2. Check Employer Details

Review the PAYE reference, Accounts Office reference, employer address, and other payroll configuration details. Incorrect employer information can cause HMRC submissions to be rejected.

3. Review Employee Records

Check the employee information included in the submission. Pay particular attention to National Insurance numbers, tax codes, dates of birth, payment details, and employment status.

4. Verify Government Gateway Credentials

Confirm that the correct Government Gateway credentials are being used and that they are associated with the relevant employer payroll account.

5. Check Sage Payroll Updates

Using an outdated payroll version can cause compatibility and submission problems. Install applicable Sage Payroll updates and ensure the software is compatible with the current payroll tax year.

6. Review Previous RTI Submissions

Check the submission history before sending another FPS or EPS. Determine whether HMRC accepted, rejected, or failed to receive the previous submission.

7. Retry Only After Correcting the Cause

Once the underlying issue has been identified and corrected, attempt the submission again. Keep a record of the submission date, payroll period, error message, and resulting status.

How to Prevent Future Sage Payroll RTI Submission Problems

Preventive payroll administration can significantly reduce RTI errors. Keep Sage Payroll updated, maintain accurate employee records, verify tax codes when changes occur, and regularly review employer information.

It is also useful to maintain a simple RTI submission record. Record the type of submission, payroll period, submission date, and acceptance or rejection status. This provides a clear history when investigating a future problem.

Before submitting payroll, review unusual employee changes, new starters, leavers, statutory payments, and payroll adjustments. Catching incorrect information before submission is generally easier than correcting a rejected report afterward.

When Should You Investigate an RTI Error Further?

An RTI error deserves further investigation when the same submission repeatedly fails, HMRC rejects the report, employee information appears correct but validation continues to fail, or Sage Payroll reports an authentication or communication problem.

Do not simply change payroll figures to make an error disappear. Payroll information should remain accurate and reflect the actual payments and deductions made during the relevant pay period.

Conclusion

Sage Payroll RTI Submission Errors can arise from incorrect employee records, employer details, Government Gateway credentials, outdated payroll software, validation problems, or communication failures. The most effective approach is to identify the exact error, review the affected payroll information, check authentication and software configuration, and confirm the previous submission status before trying again.
