P11D Test Gateway is reporting false errors

We have been providing a facility for our users to test their online File by Internet submissions to HMRC via their test gateway for a number of years.

Unfortunately this year the Test Gateway is out of synch with the live gateway and is falsely reporting errors. These errors include:

• The Cash Equivalent value must equal the Cost less the Amount Made Good
• The total benefit value must equal the total of all 1A items on all P11Ds

This is due to incorrect rounding rules being present in the Test Gateway.

You should ignore these errors as they do not occur in the live gateway.
