Hi Saureb,
As per my understanding and HMRC guide line "FPS has to be send each time employee receives the payment". So dont think so HMRC Gateway would have any issue when you report your FPS or how many time you report FPS (either for Salary or for Bonus- as long as FPS has been submitted before payment day or on the day of payment).
here is one scenario,
Multiple payroll runs in the same month
The employer has a monthly pay run on 14th of the month and employees are paid on the last banking day of the month.
In December the employer runs the December payroll on the 7th of December, and submits the payment file to Bacs on the following day.
On the 14th of December the employer runs the January payroll and submits the payment file to Bacs on the following day.
On the 20th of December the employer runs a supplementary payroll to provide employees with their annual bonus which is paid on the first banking day of the New Year.
When does the employer make an RTI submission for the various payroll runs and when is the Employer required to pay HMRC?
Employer has undertaken three PAYE calculations on respectively and in chronological order:
(a) the December pay run;
(b) the January pay run; and
(c) a supplementary pay run.
Chronologically the pay dates for these are (a), (c) then (b).
After running (c) the employer will have to re-run (b) as the year to date figures for (b) will be altered by (c).
Appropriate RTI returns will be required at or before the dates of payment (a), (c) and (b). If the employer has submitted (b) at the time the payment file was submitted to Bacs then a further submission will be required if the re-run of (b) results in changes to the amounts to be paid in January.
I believe this should be similar to your requirement, you can do supplementary run,(your bonus run), the issue which you would have it is in GB payroll there is no standard Off-cycle payment workbench and you would have to go through painful process adjusting your mid period supplementary run into your main payroll(you are asking for trouble if you do go down the route)
I could be miles away from reality here so I would advise you to get in touch with HMRC to confirm this and secondly check your SAP solution if this can be handled,
