You will have to calculate the TDS based on applicable slab after taking into consideration all the deductions. You will also have to take investment declaration from the employee.
Say total salary is Rs 3 lacs and employee makes investment u/s 80C of Rs 1 lacs.
So you need not deduct TDS since exemption limit is Rs 2 lacs and deduction u/s 80C is 1 lac. If after all deduction and exemption income is taxable only then you need to deduct TDS from salary.
