* does not maitain books of account in their business which is u/s 44AE
**filled in item 51d (as there is "NO ACCOUNT CASE)

---------------------
ITR-4
Schedule BP  (computation of income from business or profession)
---------------------------------------------------------------------------------------------          ---------
1. Profit before tax as per profit and loss account (item 43 or item 51d of Part A-P&L)**        - 152300

2. Net profit or loss from speculative business included in 1                                          - 0
 
3. Income/ receipts credited to profit and loss account considered under other heads of income         - 0
 
4. Profit or loss included in 1, which is referred to in section44AD/44AE/44AF/44B/44BB/               - 152300
   44BBA/44BBB/44D/44DA Chapter-XII-G/ First Schedule of    Income- tax Act

5. Income credited to Profit and Loss account (included in 1) which is exempt                          - 0

6. Balance (1-2-3-4-5d)                                                                                - ???

  
as logic is that item#1 - item#4 than it comes to "NIL". isn't it.
  
Please help.
