Form 16: What It Is, How to Read & Download It (2026)

If you earn a salary in India, Form 16 is probably the single most important tax document you will handle each year. It is the paper trail that connects the tax quietly deducted from your monthly pay to the return you file with the Income Tax Department. Yet most people glance at it once, see a lot of numbers, and file it away without really reading it. This guide explains exactly what Form 16 is, how its two parts differ, who issues it and when, and how to actually use it.

What Form 16 is

Form 16 is a certificate issued by your employer that states how much tax was deducted at source from your salary during a financial year and deposited with the government against your PAN. In other words, it is your employer's formal confirmation that they collected income tax on your behalf, month by month, and paid it to the exchequer. The legal basis is Section 192 of the Income-tax Act, which requires an employer to deduct tax from salary and, having done so, to give the employee this certificate.

Think of it as a receipt and a summary rolled into one. It tells you what you were paid, what deductions and exemptions were considered, how much tax was due, and how much has already been paid. That is precisely the information you need to file an accurate income tax return.

Part A and Part B: the two halves

Form 16 comes in two parts, and knowing which is which makes the whole document far less intimidating.

1. Part A — the tax summary. This is the section generated through the government's TRACES system, so it carries an authenticity that a manually typed sheet does not. It contains your name and PAN, the employer's name and TAN, the period of employment, and a quarter-by-quarter record of the amount of tax deducted from your salary and the amount actually deposited with the government. If you switched jobs during the year, you will usually get a separate Part A from each employer.
2. Part B — the income summary. This is prepared by the employer and annexed to Part A. It breaks down your gross salary, the allowances that are exempt, the standard deduction, any deductions claimed under the relevant sections for investments and eligible expenses, and finally arrives at your taxable income and the tax computed on it. Part B is where you see how your final tax figure was built up.

Put simply, Part A answers "how much tax was paid and when," while Part B answers "how that tax amount was calculated." You need both to file confidently.

Who issues it, and by when

Only your employer can issue Form 16, because only the deductor can download the certified Part A from TRACES. Employers are required to issue it by 15 June following the end of the financial year. So for a financial year ending 31 March, your Form 16 should be in your hands by the middle of June the same year — comfortably before the usual return-filing deadline.

One important nuance: an employer only issues Form 16 if tax was actually deducted from your salary. If your income was below the taxable limit and no TDS was deducted, you may not receive a Form 16 at all. That is not a mistake — it simply means there was no salary TDS to certify. You can still file your return using your payslips, bank credits and your Form 26AS.

Can you download it yourself?

This is a common misunderstanding. You cannot log in to the income tax portal and generate your own Form 16 — the certificate is produced by your employer from TRACES and handed to you, usually as a password-protected PDF. What you can and should download yourself are two related documents from the income tax e-filing portal:

1. Form 26AS, a consolidated statement of all tax credited against your PAN, including salary TDS. It lets you confirm that the tax shown in your Form 16 was actually deposited.
2. The Annual Information Statement (AIS), a broader record of your financial transactions and reported income, useful for spotting anything your return should include.

Reconciling Form 16 against Form 26AS and the AIS is the single best habit for error-free filing.

How to use Form 16 to file your ITR

Form 16 is essentially a pre-filled worksheet for your return. When you file, the figures flow across almost directly:

1. Your gross salary and exempt allowances from Part B populate the salary section of the return.
2. The standard deduction and your eligible deductions from Part B reduce your income to the taxable figure.
3. The TDS already deducted, taken from Part A, is claimed as tax paid, so you are only taxed on any shortfall — or refunded any excess.

If your employer deducted exactly the right amount across the year, filing is often a matter of confirming the numbers and submitting. Where it gets interesting is when the deducted amount was too high or too low, which is decided by how TDS was estimated. Our companion guide on TDS on salary explains how that monthly deduction is calculated and why it can end up short or in excess.

Form 16 versus Form 16A

The similar names cause endless confusion, so keep the distinction crisp. Form 16 is the TDS certificate for salary income under Section 192. Form 16A is the TDS certificate for non-salary income — things like interest from deposits, professional or contractor fees, rent, or commission. If a bank deducted tax on your fixed-deposit interest, you would receive a Form 16A for that, not a Form 16. Both are TDS certificates; the difference is simply the type of income they cover.

What to check before you rely on it

Errors in Form 16 do happen, and catching them early prevents a mismatch notice later. Before you file, verify each of these:

1. Your PAN is correct — a wrong PAN means the TDS was not credited to you.
2. The employer's TAN is present and correct in Part A.
3. The quarter-wise TDS in Part A matches your Form 26AS.
4. The salary and exemptions in Part B match your own records and payslips.
5. The deductions you actually claimed are reflected, and nothing you did not claim has been added.

If something is wrong, raise it with your employer's payroll or finance team. Because Part A is generated from TRACES, a genuine correction usually requires the employer to revise their TDS return so the corrected figures flow through.

What if you changed jobs or never got Form 16?

Two situations trip people up every filing season, and both have clean solutions.

1. You switched employers during the year. Each employer that deducted tax issues its own Form 16 for the portion of the year you worked there. To file correctly you need all of them, because your total taxable income is the sum across employers. A common problem is that each employer separately gave you the basic exemption and standard deduction, so your combined tax works out higher than either certificate suggests — the return reconciles this, and you may owe a little more.
2. You never received a Form 16. If no tax was deducted, there is nothing to certify, so no Form 16 is issued. You are still required to file if your income crosses the threshold. Use your monthly payslips, your bank statements and your Form 26AS to build the salary figure, and file on that basis. If tax was deducted but the employer simply failed to give you the certificate, ask for it — they are obliged to provide it.

In both cases, Form 26AS is your anchor. It shows every rupee of tax credited to your PAN regardless of how many employers you had, so it is the reference against which you check whatever certificates you do hold.

The bottom line

Form 16 is your employer's certified statement of the tax deducted from your salary and paid to the government, split into a TRACES-generated Part A that proves the tax was deposited and an employer-prepared Part B that shows how your taxable income was worked out. You receive it by 15 June, you cannot generate it yourself, and you use it — cross-checked against Form 26AS — to file an accurate return. Understand those points and the annual ritual of filing becomes far less daunting.
