Summary

How to submit forms P11D and P11D(b) using Sage 50 P11D.

Description

Once you process all of your employees' benefits and checked they're correct, you can submit to HMRC. Sage 50 P11D makes it easy to submit forms P11D and P11D(b) online.

HMRC's deadline for you to submit these forms is 6 July 2025. If you fail to submit on or before this date, you may be subject to a fine.

Resolution

If this is your first submission, check your ▼ submission settings are correct in your software.

If you haven't already done so, register for the PAYE Online for employers service with HMRC. To register, go to Gov.UK.

After you register, you receive your user ID and activation code in the post. When you receive your user ID and activation code, you have 28 days from the date on the letter to activate the service.

You can then enter your HMRC User ID and password into Sage 50 P11D. Enter your submission settings.

 NOTE: If you have more than one company with different credentials, you can change these as you make your P11D submissions.

Before you can submit

The submission isn't possible unless you've completed your Employer Declaration.

For help with doing this, follow the print your Employer's P11D(b) Declaration article.
