Outstanding Issues

IRIS Business Tax

HMRC Filing Error 

An HMRC filing error displays for a user that tries to file a return when a RDEC claim with Box 657 is ticked. 
An automatic workaround has been introduced into Business Tax, so when the box is ticked it will not be printed in Box 657.

Workaround advised by HMRC
Do not tick Box 657 when submitting the CT600 return. This is a HMRC filing issue and is expected to be fixed by April.
