Is it necessary for my employer to deduct income tax from my Salary?

Yes. It is his duty as per law to deduct tax from the income paid to you by him. This deduction is called TDS (Tax deducted at source). TDS is deducted each month by employers based on tax projections declared by the employee at the beginning of each financial year. In case you think that you may not have any tax liability, you may inform your employer about your claims (including loss for setting off) and demonstrate that there is no tax liability in your hand for that particular year.
