Form 16 Decoded: Every Field Explained for Salaried Employees

Most salaried employees receive Form 16 every June, glance at the bottom-line tax figure, and forward the document to whoever files their ITR. That routine has worked for years and will probably keep working. But it has costs. The fields you don''t check are the ones most likely to be wrong, and when they''re wrong they create problems at filing time that take weeks of back-and-forth to resolve. Knowing what each field actually means — and which fields commonly contain errors — turns a five-minute check into a habit that prevents the worst kinds of tax-time grief.

This guide walks through Form 16 line by line, with particular attention to the fields that tend to be wrong, the cross-checks that catch errors before filing, and what to do when something doesn''t add up. Form 16 is being replaced by Form 130 from Tax Year 2026-27 onwards under the new Income Tax Act, 2025, so the article also covers what changes and what stays the same.

What Form 16 Actually Is

Form 16 is a TDS certificate issued under Section 203 of the Income Tax Act, 1961 (and Rule 31 of the Income Tax Rules, 1962). It certifies two things: that your employer paid you a specific amount of salary during the financial year, and that they deducted a specific amount of TDS from it and deposited that TDS with the Government of India. Think of it as a receipt for the tax your employer collected on the IT department''s behalf.

The certificate has two structurally distinct parts that come from different sources. Part A is generated by the Income Tax Department itself through the TRACES portal, after your employer files their quarterly TDS return (Form 24Q). It shows the TDS challans your employer deposited each quarter and confirms the deposits actually reached the government. Part B is prepared by your employer''s payroll system and contains the detailed breakup of your salary, the exemptions and deductions claimed, and the tax computation that produced the TDS amount.

Both parts together form one complete certificate. An employer issuing only Part B without Part A is technically issuing an incomplete document; some smaller employers do this to skip the TRACES step, and you should ask for the complete version.

When You Should Receive It

Rule 31(3) of the Income Tax Rules, 1962 sets the issuance deadline at 15 June of the assessment year following the financial year in which TDS was deducted. So Form 16 for FY 2025-26 (income earned April 2025 through March 2026) must reach you by 15 June 2026. The reason for the mid-June deadline rather than April: employers can only generate Part A from TRACES after they file their Q4 TDS return (Form 24Q), and Q4 returns are due 31 May. That gives employers two weeks to download Part A, combine with their own Part B, and distribute.

If your employer misses 15 June, the penalty under Section 272A(2)(g) of the old Act is ₹100 per day per certificate, capped at the TDS amount. For employees this is largely theoretical — the IT department prosecutes employers for systematic non-compliance, not isolated delays — but you have grounds to escalate if a certificate is significantly overdue. A written request to HR (email is sufficient) usually resolves it. If they still don''t comply, you can complain to the IT department through the e-filing portal, which prompts the employer''s TDS officer to act.

For employees who switched jobs during the year, every employer who deducted TDS must issue a separate Form 16 for the period you were with them. Three employers in a year means three Form 16s. All three have to reconcile with your AIS, and all three must be reported in your ITR.

Part A: The TRACES-Generated Section

Part A is the section most people don''t bother reading because it looks like a wall of identifiers. That''s a mistake. The errors that surface in Part A are the ones that prevent your TDS from showing up correctly in Form 26AS, which in turn means you can''t claim it as credit in your ITR. The five fields that genuinely matter:

1. Employer details: Name, address, PAN, and TAN (Tax Deduction Account Number). The TAN is the identifier under which your employer files all their TDS returns. If the TAN on Form 16 is wrong, the entire chain of TDS attribution breaks. This is rare but does happen during corporate restructurings — verify it matches the TAN on your monthly payslips.

2. Employee PAN: Your PAN must appear correctly. A single digit wrong in the PAN means the TDS gets credited to a different person''s tax account. Cross-check with your PAN card. If wrong, your employer must file a TDS correction return with the right PAN — a regular revised Form 16 won''t fix it.

3. Assessment Year and Period: Form 16 for FY 2025-26 will show "Assessment Year 2026-27" and the period as 1 April 2025 to 31 March 2026 (or your actual employment dates if you joined or left mid-year). The dates must match your actual employment dates exactly. If you joined on 7 May 2025 but Form 16 says "01-04-2025 to 31-03-2026," that''s an error worth getting fixed because it implies salary was paid for April when it wasn''t.

4. Quarterly TDS summary: Four rows showing TDS deducted and deposited each quarter. Each row should match the salary TDS shown on your payslips for that quarter. Discrepancies here are the single most common Form 16 error — about 20% of certificates I''ve reviewed have at least one quarter mismatch, usually because of correction statements that didn''t fully process.

5. Challan-wise deposit details: The actual challan numbers and deposit dates. These should match the challans visible in your Form 26AS for the same period. If a challan exists in Form 16 but not in 26AS, the deposit didn''t process correctly — your TDS credit is at risk.

Part A is digitally signed by the employer''s authorised signatory. The signature is essential — without it, the document isn''t a valid TDS certificate. Almost all modern payroll systems sign automatically; smaller employers occasionally forget. Check the signature panel before filing.

Part B: The Salary Breakup and Tax Computation

Part B is where the actual tax math lives, and it''s also where most employees should focus their review effort. The standard structure runs through the following sections:

Gross Salary (Section 17): The total salary paid during the year, broken into salary as per provisions of Section 17(1), perquisites under Section 17(2), and profits in lieu of salary under Section 17(3). The first line — basic salary plus dearness allowance plus other components — should match the sum of the gross salary figures on your monthly payslips. If it doesn''t, something has been omitted or double-counted.

Allowances exempt under Section 10: HRA (under what is now Section 12 of the new Act, formerly Section 10(13A)), LTA, and various other exempt allowances. The exempt amount appears here as a deduction from gross salary. For HRA in particular, the exempt amount is the lower of three calculations — actual HRA received, rent paid minus 10% of basic salary, or 50%/40% of basic salary depending on city — and this is one of the most error-prone fields. Check that the HRA exemption figure here matches what you''d compute manually with your rent receipts and basic salary numbers.

Standard Deduction: Under the new regime for FY 2025-26, this is ₹75,000. Under the old regime, ₹50,000. The applicable figure depends on which regime your employer used to compute your TDS. If you elected the old regime via Form 12BB and the certificate shows ₹75,000, your TDS was computed under the wrong regime — material correction needed.

Professional Tax (Section 16(iii)): The state-level professional tax deducted from your salary, typically ₹2,400 to ₹3,000 per year depending on the state. Karnataka, Maharashtra, and West Bengal levy it; Delhi doesn''t. Verify against your payslips.

Net Salary: Gross salary minus Section 10 exemptions minus Section 16 deductions. This is your "income from salary" head as it will appear in your ITR.

Other Income (if reported): Income from other sources — typically interest income — that you declared to your employer for inclusion in TDS computation. Many employees skip this and let their full TDS be computed on salary alone, then add other income at ITR time. Either approach works.

Chapter VI-A Deductions: 80C, 80D, 80E, 80CCD(1B), and so on — the deductions you claimed by submitting investment proofs to your employer. Each deduction should appear with the specific instrument and amount. If you submitted ₹1.5 lakh of 80C proof but the certificate shows ₹1 lakh, your TDS was computed on a higher taxable income than necessary; you''ll claim back the difference at ITR time.

Total Income and Tax Computed: The taxable income after all deductions, the tax computed under the chosen regime''s slabs, the Section 87A rebate (₹60,000 in the new regime if total income is ≤ ₹12 lakh), the 4% Health and Education Cess, and the final tax payable. The final figure should match the total TDS in Part A. If they don''t reconcile, somewhere in the year the employer either over-deducted or under-deducted, and you''ll see the difference as either a refund or additional tax in your ITR.

Cross-Checking Against Form 26AS and AIS

Form 16 alone isn''t enough. Before filing your ITR, you should reconcile three documents: Form 16 itself, your Form 26AS (the IT department''s record of all TDS deposited under your PAN), and your AIS (the Annual Information Statement, which consolidates Form 26AS plus dividend, interest, mutual fund, and securities transaction data from multiple sources).

The expected match: total salary in Form 16 Part B should equal the salary line in AIS. Total TDS in Form 16 Part A should equal the TDS shown under your PAN in Form 26AS for the relevant TAN. Both should appear as filed-and-credited transactions, not just deposited-but-pending.

Three common mismatches and what they mean:

• Form 16 shows TDS but Form 26AS shows less. The employer deducted TDS from your payslip but hasn''t fully deposited it with the government, or has filed an incorrect TDS return. Resolution: ask the employer to file a correction statement. Do not file your ITR with the Form 16 figure if Form 26AS shows less — you can only claim TDS credit for what 26AS reflects.
• AIS shows salary higher than Form 16. Usually means a previous employer''s salary is also showing up. Submit Form 12B disclosing the previous employment and reconcile both Form 16s in your ITR.
• AIS shows interest income that Form 16 didn''t consider. Bank interest, mutual fund interest, or savings account interest that your employer didn''t know about. Add it to your ITR under "Income from Other Sources." This is the most common reason employees end up owing self-assessment tax at filing time.

What to Do When Something is Wrong

Errors in Form 16 are common enough that knowing the resolution path matters. The path depends on what''s wrong.

Wrong PAN, wrong TAN, wrong assessment year: Your employer must file a TDS correction return on the TRACES portal. Once processed (usually 1-2 weeks), they can regenerate Part A and reissue Form 16. A revised Form 16 alone — without a correction statement — won''t fix the underlying TDS attribution.

Wrong salary figure in Part B: Your employer reissues Form 16 Part B with the corrected figure. If TDS was already correctly deducted on the right salary, no correction statement is needed; just a corrected Part B.

Wrong deduction amount (e.g. 80C declared as ₹1L but should be ₹1.5L): Two paths. If your employer can reissue with the corrected figure before you file ITR, that''s cleanest. If not, claim the higher deduction directly in your ITR — the IT department processes the ITR figure, not the Form 16 figure, so you''ll get the correct refund.

Quarterly TDS mismatch in Part A: Almost always a correction statement issue. Ask HR specifically for a "Form 24Q correction return" — most HR teams know to escalate this to their TDS partner.

Get any correction in writing. An email saying "we will issue a corrected Form 16" is your evidence if there''s a delay. The legal obligation to issue accurate Form 16 sits with the employer, not with you.

The Form 130 Transition Coming Next Year

This is the last year of Form 16 as you know it. From Tax Year 2026-27 (income earned 1 April 2026 to 31 March 2027), the TDS certificate for salaried employees becomes Form 130 under Section 402 of the new Income Tax Act, 2025. Issued by 15 June 2027, after the Q4 quarterly TDS return (now Form 138, replacing Form 24Q) is filed.

What changes:

• Three parts instead of two. Form 130 has Part A (TRACES-generated TDS summary), Part B (quarter-wise reconciliation of salary paid and TDS deducted), and Part C (employer-prepared salary breakup with deductions, equivalent to old Part B).
• New section references. The deductions that used to reference Section 80C, 16(ia), 10(13A), etc., now reference the new Act sections — for example, Schedule XV read with Section 123 for what was 80C, and Section 19 for what was 16(ia) standard deduction.
• Mandatory digital issuance. Form 130 must be issued through TRACES; the offline option that some employers still used for Form 16 is no longer available.
• Period of employment field. Form 130 explicitly shows the dates you worked for the employer during the tax year — useful for mid-year joiners and leavers.

What stays the same: the substantive purpose, the cross-check requirement against Form 26AS and AIS, the 15 June deadline, the penalty for late issuance, and the role of the certificate in ITR filing. If your employer''s payroll software is modern, the transition will be transparent to you. If you''re at a smaller employer using older systems, June 2027 may bring some confusion.

Frequently Asked Questions

What is the deadline for receiving Form 16?

15 June of the assessment year following the financial year in which TDS was deducted. For FY 2025-26 income, the deadline is 15 June 2026. Employers face a penalty of ₹100 per day per certificate under Section 272A(2)(g) of the old Act if they miss this deadline. For Tax Year 2026-27 onwards, Form 130 (which replaces Form 16) must be issued by 15 June 2027.

Can I file my ITR without Form 16?

Yes. Form 16 makes ITR filing easier but is not legally mandatory for filing. You can use your salary slips, Form 26AS, and AIS to compute your taxable salary and tax deducted. However, if your employer was supposed to issue Form 16 (because they deducted TDS), they remain legally obligated to do so. You can file your ITR using alternative documentation while still pursuing the Form 16 from your employer.

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

Part A is generated by the Income Tax Department through the TRACES portal and contains the official record of TDS deposited under your PAN — quarterly breakup and challan-wise deposit details. Part B is prepared by your employer and contains the detailed salary breakup, exemptions claimed, deductions allowed, and the tax computation. Both must be issued together as one complete certificate.

What is Form 130 and how is it different from Form 16?

Form 130 is the new TDS certificate for salaried employees under the Income Tax Act, 2025, replacing Form 16 from Tax Year 2026-27 onwards. It is issued under Section 402 of the new Act (replacing Section 203 of the old Act). Form 130 has three parts instead of two — Part A (TDS summary from TRACES), Part B (quarterly reconciliation), and Part C (salary breakup and deductions). The substantive purpose and cross-check requirements are unchanged. Form 16 will still be issued for FY 2025-26 income; Form 130 begins with FY 2026-27 income.

What should I do if my Form 16 doesn''t match my Form 26AS?

Don''t file your ITR using the Form 16 figure if Form 26AS shows less TDS — you can only claim what 26AS reflects, not what Form 16 claims. Contact your employer in writing and ask them to file a TDS correction return on TRACES. Once the correction is processed (usually 1-2 weeks), your Form 26AS will update and your employer can reissue Form 16. If the discrepancy is small and the deadline is close, file using the lower 26AS figure and revise your ITR after the correction is processed.

Do I need to keep my Form 16 after filing the ITR?

Yes, for at least 7 years. The IT department can reopen assessments going back several years under Section 263 (was Section 139) of the new Act, and Form 16 is your primary evidence of salary and TDS for that period. Most CAs recommend keeping Form 16 along with payslips, investment proofs, and ITR acknowledgement for 8 years — the same period for which capital losses can be carried forward. Digital copies are acceptable; print is not required.

What happens if my employer doesn''t issue Form 16?

You have multiple recourse paths. First, send a written request to HR (email is sufficient) — most cases are resolved at this step. If they still don''t comply, file a complaint with the IT department through the e-filing portal''s "Grievances" section, which prompts the employer''s TDS officer to act. The employer faces a penalty of ₹100 per day per certificate, capped at the TDS amount, under Section 272A(2)(g) of the old Act. In the meantime, you can file your ITR using salary slips, Form 26AS, and AIS — Form 16 is convenient but not legally mandatory for filing.
