Adjust a filed CIS deduction
Edit a filed CIS deduction suffered amount by submitting an Employer Payment Summary (EPS) with the adjusted amount.
- In the Payroll menu, select RTI Filings.
- If you already have an EPS scheduled, click the EPS to open it. Otherwise, click Schedule EPS.
Enter the adjustment amount under Report CIS Deductions as a negative amount if you filed an overpayment, or as a positive amount if you filed an underpayment.
For example, if the original amount you filed was 100 and should be 80, enter '-20' to correct the filing.
- Click Schedule EPS.
The Real Time Information (RTI) service automatically submits your EPS filings to HMRC at month end.
