This is a first for me so thought I would share...
New accountant requested our client Moneysoft payroll back up rather than do a Mid year start as they presumably noticed that we use the same software as them. They were not aware that Moneysoft does not protect your HMRC log-in details and if you open the back up in Notepad you can view the agent log in details on each RTI submission.
If you manually edit the file to try and remove this then you corrupt it and it is useless. Moneysoft don't to seem to have any official guidance on this but I would suggest that you do not pass agent backups to new accountants.
Anyone else had issues around this or even worse given away a Moneysoft back up to a new accountant? If so change your HMRC password immediately which no doubt will mess up any other HMRC submissions that you are doign until each software instance has been updated.
