Limited Company Query!

T.C.

I have a self-employed client, a builder, who has just given me his accounts to sort for the year. However, he informs me that he also started a limited company with one other person to finance the building of a house. He tells me that his partner's accountant is dealing with the limited company accounts. I don't deal with limited companies, so what should I be asking for with regard to paperwork, if anything, if I am doing his self-assessment tax return? Help appreciated.

For his Self Assessment any income that belongs to him.

From said Limited Company there may be:-

A Salary
Dividends
Benefits In Kind
