Firstly, sorry if this is a daft question!
I have recently filed a SA return for a client - it's only the second one I have done as an agent, I'm rather new to this. They are expecting to hear from HMRC with a bill and explanation of how to pay. Does this happen? According to HMRC website, "a bill will be issued by post if a paper return is done". The first return I completed online for another client resulted in a bill being issued to me as their agent, and the client, about a week after I competed it.
If they don't receive a bill, how do they pay? Do I have to share the HMRC bank details etc with the client? As all the details of what's owed and how to pay are on my agent HMRC login.
