I currently run a clients monthly payroll (to include directors and senior management) using sage and the client themselves undertake a weekly payroll using another software provider.
Historically it's always been a case that at year end, client provides me with all the data/reports from their weekly payroll and I would collate both payrolls together and submit one P35 accordingly.
Has anyone any ideas if under RTI this setup can still continue I.e. I process monthly and submit to HMRC each month and client does weekly and submits to HMRC each week ??
You can continue with the practice, but at least an hour before your first payment FPS in either piece of software you must do an EAS (Employee Alignment Submission) from one of the software packages that includes all employees currently employed in the scheme.
