When did you join your current employer? Please share your date of joining first, as it will help you in getting a proper response. If you joined them in the current financial year 2013-14 (Assessment Year 2014-15) or after April 2013, you will receive your Form 16 next year after the completion of FY13-14 (by March 2014 or as soon as the computation is done by the employer for the respective period). However, you can find the deduction details in your salary slip every month.
For example, in your current month's salary slip, you can notice the deducted amount (if/as applicable).
Further Information About Form 16
At the end of the financial year, the company/employer issues a Form 16 to an employee, which contains details about the salary earned by the employee and how much tax has been deducted, including details of the deducted tax for each month from April to March.
Lastly, there is no need to worry because Form 16 is actually a statement providing details about the tax deducted by the employer on behalf of the employee. The same amount will be paid to the government by the company, so they are required to provide Form 16 to the respective employee.
