proprietor Account

No... can't required to be disclosed

no, you have to file itr-3as and there you have to mention your pl and balance sheet. since you are filling only business data there no need to file personal assets but it is advisable to prepare separate balance sheet also.

No need to show R.H.in B.S ,R.H is not a B.A.

but for proprietor there is no difference between personal asset and business asset unlike partnership firm and company. and tds is deducted on new residential property purchased and old residential property got sold. Mr.A is having business income so need to prepare Profit and loss and Balancesheet. so new residential property purchased need a disclosure in balancesheet? ??
