Please advise, during F&F settlement if an employee had declared IT savings making the TDS as Zero and hence monthly the TDS was not deducted, should we deduct the TDS for all the months clearing the IT declaration and make the settlement ?
Yes you can deduct for all the months and do the settlement.
Ideally, the employee should provide all the proofs before exiting. Frequently, this does not happen and the company should therefore nullify the declaration details and deduct the TDS. The employee can claim the benefit of investments in the next company.
If an employee gets a hike in the month of May-22 but with effective from Jan-22, How should we proceed with the TDS deduction,
No choice but to deduct the TDS in the current year.
