How to prepare final accounts with a bank summary?

How to prepare Final accounts just by using a bank summary? what if the cash is insufficient to cover the deposits in the bank?

By using the information of the entire bank statement, you will be able to come across items which would construe income & expense of the assessee, and which would go to P/L account. For a small individual, it would just be fund transfers (cash deposited, withdrawn, etc.), but will be in detail for others.

Also guide, what should be the treatment for repayment of loans which were not shown in the balance sheet date last year?

The loan should have been reflected in the previous year itself, and if they were not, the previous year financials needs to be amended, and receipt of loans is a capital receipt not chargeable to tax, however the interest payments are allowed as deductions. This would also answer your first question, where after showing the receipt of loan, there would be enough cash to cover deposits in the bank. The loan can be shown as cash withdrawn from bank.

Also, what should be the treatment of loans and advances realised which were not shown in the previous balance sheet? 

Almost same as above.

waiting for your valuable suggestions..!

Hope this helps!

I agree with Aliasgar ,  as  far as your first query is concerned , to make it more simple you can export the bank statement in excel and then further pin down on evry debit /credit identifying it as p&l item or b/s , resultant after ur above exercise will be completed ur trial balance will be ready
