Dear Susmitha,
The TDS is Deducted on Taxable Salary only (on basis of different slabs for the year)..
The Taxable salary is calculated after deducting various exemptions and deductions from the Salary. The deductions and exemptions depends upon the Investment Declaration provided by the employee and salary structure.
So, it is better first share detailed breakup of the Salary, investment declarations and applicable deductions & allowances.
