Form 16 is the final certificate issued by your employer giving details of the salary you have earned and the tax deducted on your behalf and paid to the government. This article addresses the following questions:

  • Form 16A and Form 16:
  • What if you have changed jobs?
  • What if you cannot get form 16 from the previous employer?
  • Do you have to attach Form 16 with I-T returns?
  • What other particulars should be checked in Form 16?
  • What if there is an error in figures in Form 16?

Didn’t get tax break? Take the refund route
A tax refund could be due to the following: tax deduction at source at a rate higher than the actual tax payable; wrong (ie, higher) estimation of income while computing advance tax liability; not reporting all investments to the employer while the employer deducts taxes on salary; and claim of exemption in tax returns.
