I joined a company in Nov 2013, where my salary was 13000 approx. I was paid in cash. When I resigned in Jan, 2017 my salary was around 18000 still paid in cash. Only professional tax was cut and no TDS was cut and my salary is below income tax with no documentations such as Form 16. Since, my salary was less, I never deposited the cash in bank. But I have joining letter, salary slip, appreciation letter. My salary does not have breakups but only the amount I will receive and the amount subtracted because of professional tax. Will I face any issue while joining a new company at the time of verification process post my MBA? What should I do now?
