URGENT help needed: Cash Salary Slip -

Hi friends,

I've been working in a very small CA firm of 5 ppl where they pay salary by CASH of Rs.5000/- per month to me. I need last 3 mnths payslips to show to immigration which I must get the same from my employer now.

First I want to know if salary slips are given if there are no deductions like TDS, EPF, PTax, etc. in my case or will that look doubtful to show NO DEDUCTIONS AT ALL? I can mention in the covering letter that these deductions are not applicable to me but will it look doubtful? If yes, then I can just go ahead with showing salary certificate of 12 mnths.

Secondly, if my boss gives me salary slips for last 3 months, how should he show the breakup of Rs.5000 in the slip... like allowances etc.? 

Also, for 'proof of payment of Income tax', can we submit the electronically generated 'ITR-VAcknowledgement'  to Immigration or do we need to submit the entire income tax return?

Thanks a lot.
