IVA - PAYE and CIS returns

Hello,

I have a client which has entered an IVA mid-month. Can anyone advise on how monthly PAYE / CIS returns can be made for the periods pre- and post-IVA commencement. The client has indicated that their online filing allows for only a single monthly return to be filed for each.

The pre-commencement will form part of the creditors' claims in the IVA and the post-commencement liabilities need to be paid as normal.

I would be grateful for any help.
