The government uses this information to calculate the amount of income tax you owe or the refund you might be eligible for.

    • Form 16 is one of the most important documents required for ITR filing to a salaried person. It is a Tax Deducted at Source (TDS) certificate given by an employer and provides a detailed break-up of the salary and the tax deducted on it.

    • You can ask for Form 16 from your employer if no TDS is deducted from your salary.
      Part A and Part B are the parts in Form 16.
      Part A:
      This part provides details including the tax deducted by your employer during a year; the Permanent Account Number (PAN) and TAN of your employer.
      Part B:
      This gives information about the gross salary break-up details such as exempt allowances, perquisites, and so on.
  2. Bank / Post Office Interest Certificates:
    • This is another most important documents required for ITR filing. Interest earned from savings accounts, post office savings, fixed deposits, and recurring deposits is taxable per income tax regulations.
    • To exactly report this, individuals must gather interest certificates from banks and post offices, detailing the interest income from various sources.

    • Downloading Form 26AS from the new income tax portal is important, aiding as a tax passbook detailing deducted and deposited taxes against your PAN. Cross-checking with TDS certificates and interest certificates is mandatory.
  4. Tax-saving Investment, Expenditure Proofs:
    • Collecting proof of tax-saving investments and expenditures is significant for claiming deductions. It’s worth mentioning that individuals can claim such benefits in the old tax regime while filing their ITR.
