I have a limited company client with a single director payroll that I process quarterly.
A couple of days ago with the client's permission I filed March RTI including the final return EPS using Moneysoft.
Yesterday they told me in passing that the company had suffered CIS deductions from customers throughout the year. As I had no knowledge of this previously none of this has been reported via RTI.
How am I best to correct this? I know we are still in year officially but with the final RTI already having been filed, I am seeking advice as to what is best to do.
