I am cross-checking Form 16 before filing my return

How do I verify Form 16 against AIS and 26AS before filing ITR?

Sec 192Sec 139Sec 139(5)Sec 234FVerified 2026-08-11

Cross-check Form 16 Part A (monthly TDS) against Part B (annual computation), then match the totals with Form 26AS and the AIS on the portal — any mismatch should be resolved before filing. Choose the correct ITR form for your income type, since a wrong form makes the return defective under section 139(9), and file by 31 July to avoid late-fee interest under section 234F.

Your legitimate options

Every route the statute actually gives you — with its condition, cap and deadline.

RouteConditionCap / deadline
Form 16 Part A vs Part BPart A has employer TAN, your PAN, and monthly salary/TDS; Part B has the annual computation of income and deductionsBoth parts together form the complete employer certificate
AIS and Form 26AS reconciliationMatch all TDS, interest, dividends and capital gains reported in AIS with your records before filingUnmatched or missing entries cause notices or refund delays
ITR form choiceITR-1 (salary+other sources), ITR-2 (capital gains/property), ITR-3 (business/professional), ITR-4 (presumptive)Wrong form = defective return u/s 139(9)

The #1 trap

Trusting the pre-filled ITR blindly — pre-filled figures pull from AIS/26AS, which can contain employer errors, duplicate TDS or income from a previous employer that was later corrected. Also, many taxpayers file ITR-1 when they have capital gains or rental income, and the return comes back defective under section 139(9) with no time left before the 31 July due date.

The decision path

Follow it top to bottom — the first condition that matches is your answer.

  1. IF your employer issued Form 16 → verify Part A monthly TDS totals against Part B annual figures.
  2. IF the AIS or 26AS shows entries not in Form 16 → reconcile with payslips and bank statements before filing.
  3. IF you have salary and only interest income → ITR-1 is correct for residents.
  4. IF you have capital gains, rental income or foreign assets → use ITR-2 or higher; ITR-1 will be defective.
  5. IF you have business or professional income → use ITR-3 (actual) or ITR-4 (presumptive).
  6. IF a mismatch remains at filing → file with the best available figures and note the dispute; do not suppress income.
  7. IF you miss the 31 July due date → a late fee under section 234F applies and revised returns lose flexibility. [VERDICT: reconcile AIS before you trust the pre-filled form.]

Worked example

Ankit, finance manager reconciling before his first ITR filing

Ankit downloads his Form 16, which shows salary income of ₹13,00,000, standard deduction of ₹75,000 and TDS of ₹1,05,000 deducted by the employer. He opens the AIS on the income-tax portal and sees the same salary and TDS, plus fixed-deposit interest of ₹18,000 from a bank where he holds an FD, and dividend income of ₹6,500 from shares — none of which appears in his Form 16, because the employer only reports salary. His Form 26AS shows the employer's TDS of ₹1,05,000 and additional TDS of ₹1,800 cut by the bank on the FD interest under section 194A. Ankit adds the interest and dividend to his return, because AIS entries are pre-filled into the ITR and suppressing them invites a notice. His total income becomes ₹13,00,000 minus ₹75,000 plus ₹18,000 plus ₹6,500, which is ₹12,49,500, and the bank's ₹1,800 TDS becomes a credit in his return. Because he has dividend and interest income, ITR-1 still works for a resident with only salary and other sources, so he files ITR-1. His colleague who sold shares for a capital gain must file ITR-2, and a friend with freelance consulting income files ITR-3. Ankit verifies that the pre-filled salary matches his Form 16 exactly, because a duplicate entry from a previous employer would overstate his income. He files by 31 July, paying the small balance of tax computed, and keeps the Form 16, AIS and bank statements together. A quick call with us dials in the final figure. Ankit also compares the employer's TDS amount in Form 16 Part A with the quarter-wise entries in Form 26AS, because a missing quarter means his TDS credit is short and his refund is delayed. If the AIS shows an interest entry from a bank account he closed years ago, he checks whether it is a duplicate or a genuine missed credit before removing it, because deleting a genuine entry can cause a mismatch notice. The pre-filled ITR is convenient but not authoritative: he edits the salary figure only if the employer's correction statement (Form 26) changed it after Form 16 was issued. If his total income exceeds the threshold or he has any income to declare, the 31 July due date controls, and filing late attracts a fee under section 234F of ₹5,000 (₹1,000 for small incomes). A quick call with us dials in the final figure.

Questions people actually ask

What is the difference between Form 16 Part A and Part B?

Part A carries employer details, your PAN/TAN and month-wise salary and TDS; Part B contains the annual computation of total income and deductions claimed by the employer.

What if the AIS shows income not in my Form 16?

Add the extra income to your return — AIS is pre-filled into the ITR and unmatched entries trigger notices. Reconcile against bank statements and 26AS first.

Which ITR form should I use?

ITR-1 for salary plus other sources (residents); ITR-2 when you have capital gains, rental income or foreign assets; ITR-3 for business/professional; ITR-4 for presumptive income.
