Hi
Receiving cash payments of salary is not recommended. Being a salary payment exceeding Rs. 10000, your employer would not be allowed for such salary expense also.
If your employer does not agree and cash payments are to be made, we can manage things in legal manner too.
Since it is a very obvious and genuine fact for doctors to have income in cash from practice. So, instead of showing salary by your employer, it would be sharing of professional fees. You can it under income from Business/Profession, claim 44ADA presumptive taxation where 50% of the gross receipts are presumed to be income and pay taxes accordingly.
However, you should consider depositing weekly/fortnightly depositing cash in bank accounts making the deposit amounts in lesser amounts.
We may discuss further on the issue to reach out at optimum tax solution.
