How to save tax on salary income

What about TDS deducted by the employer? If TDS credit is available, tax will reduce further.

Minimum five year is the lock-in period in investments that are eligible for deduction u/s 80C etc.

Open a PPF account, initially  for  five years you can not withdraw, but after five years you will  get tax benefit  by withdrawing and  depositing , as withdrawals  are  tax  free, there would  be  no  tax, and deposits  would  fetch 80C benefit 

Hi,
