What is the most important document for ITR filing?

Form 16 (for salaried employees) and AIS/Annual Information Statement are the two most critical documents. Form 16 summarizes your salary and TDS deducted. AIS shows all financial transactions reported to the Income Tax Department — interest income, dividends, securities transactions, and more. Always reconcile your ITR with AIS before filing.

Where can I download Form 26AS and AIS?

Both Form 26AS and AIS are available on the Income Tax e-filing portal at incometax.gov.in. Log in with your PAN credentials, go to 'e-File' > 'Income Tax Returns' > 'View AIS' for AIS/TIS, and 'Services' > 'View 26AS' for Form 26AS.

Do I need all documents if my only income is salary?

For salaried individuals with no other income, you need: Form 16 (Part A & B), AIS/TIS, Form 26AS, bank account details (IFSC, account number), PAN, and Aadhaar. If you have savings account interest or FD interest, you also need bank interest certificates. Investment proofs are needed only for deduction claims under 80C, 80D, etc.

What documents are needed for ITR with capital gains?

For capital gains ITR: broker's P&L statement and contract notes for equity/F&O trades, Consolidated Account Statement (CAS) from CAMS or KFintech for mutual funds, sale deed and purchase deed for property sales, and indexed cost workings. Short-term and long-term gains must be reported separately.

Can I file ITR without Form 16?

Yes. Form 16 is not mandatory for filing ITR. If you don't have Form 16, you can compute your income from your salary slips, bank statements, and reconcile it with Form 26AS and AIS. However, having Form 16 (Part A and B) makes the process much simpler and accurate.
