Form 16 is your most important ITR document. Understand Part A vs Part B, how to use it, and what to do if you don't get it.
Part A is the official government record generated from the TRACES portal by your employer. It shows: employer's TAN number, your PAN, quarterly TDS amounts deducted and deposited with the government, and the acknowledgement numbers. Part A has a TRACES watermark and is digitally signed — it cannot be modified by the employer.
Part B is prepared by the employer itself (not from government portal). It shows: complete salary structure (basic, HRA, all allowances), deductions claimed during the year (80C investments you submitted, HRA exemption calculated, standard deduction ₹75,000 in new regime), and final net taxable salary. Part B is essentially your annual salary computation sheet.
What to check: Compare Part A (TDS deposited) with Part B (TDS calculated). Both should match. Also compare with Form 26AS — the TDS in all three should be identical. Any mismatch = contact HR immediately before filing ITR.
Step 1 — Gross Salary (Part B): This is your total CTC-based income. Use this as your "Salary" figure in ITR. Step 2 — Exemptions (Part B Section 10): HRA exemption, LTA, other allowances. Already calculated — just copy to ITR. Step 3 — Standard Deduction: ₹75,000 (new regime) or ₹50,000 (old regime) — already deducted in Form 16. Step 4 — Net Taxable Salary: After all deductions. This is your salary income for ITR. Step 5 — TDS Deducted (Part A): This credit appears automatically in your ITR from Form 26AS. Your refund = TDS deducted minus actual tax liability.
Employers are legally required to issue Form 16 by June 15. If yours doesn't: (1) Email HR formally requesting Form 16 with deadline reminder. (2) Download Form 26AS from incometax.gov.in — it shows exact TDS deducted by employer. (3) Download AIS from IT portal — shows salary income reported. (4) Use salary slips to reconstruct annual income. (5) File ITR without Form 16 using above documents — the IT portal pre-fills salary from employer's TDS returns. You can also report employer to your Assessing Officer for non-compliance.
If you changed jobs, you'll receive Form 16 from EACH employer. Common mistake: previous employer shows full tax deduction assuming no new employer, while new employer also deducts tax — resulting in DOUBLE TDS! To avoid this: inform new employer about previous salary with Form 12B. Combine both Form 16s when filing ITR. Total income = sum of both. TDS credit = sum of TDS from both. Often results in a refund.
Form 16 (TDS on salary) is different from: Form 16A — TDS on non-salary income (FD interest, professional fees, rent received). Banks issue Form 16A for TDS deducted on FD interest. Form 16B — TDS deducted by property buyer (if you sold property, buyer deducts 1% TDS). Form 16C — TDS on rent paid by tenant above ₹50,000/month. All these appear in Form 26AS and AIS.
