Sub contractor client has no CIS paperwork
A new client came to see me yesterday.
He worked for a contractor for 17 weeks last year.
He raised invoices to the contractor.
The contractor issued paperwork which shows full amount of invoice less 20% tax, and my client was paid the net amount.
There seems to be no formal CIS certificates.
My client should be due a tax refund.
What paperwork do I need to get the tax refund for him?
