Form 16, explained properly
What Form 16 actually certifies, what lives in Part A versus Part B, the employer's duties and deadlines around it, and why a clean payroll year makes it an export instead of a project.

What Form 16 is
Form 16 is the employer's annual certificate of salary paid and tax deducted at source under Section 192: the document an employee uses to file their return and to prove their income-tax position to anyone who asks. It is generated from the employer's quarterly TDS returns (Form 24Q): Part A comes from the TRACES system against the deposited TDS, and Part B is the employer's detailed salary annexure. If no TDS was deducted because the projected liability was nil, a Form 16 is not mandatory — though a salary certificate is good practice; where any TDS was deducted, issuing Form 16 by the annual deadline (15 June following the financial year, as currently prescribed) is a duty, not a courtesy.
Part A and Part B, precisely
Part A is the deduction-and-deposit certificate: employer and employee identifiers (TAN, PANs), the period, and the quarter-wise summary of TDS deducted and deposited, generated and downloaded from TRACES; it is the government-verified half. Part B is the computation annexure: gross salary and its components, exemptions claimed, standard deduction, Chapter VI-A deductions per the regime, taxable income and the tax computed: the employer-prepared half that must reconcile with Part A's totals and with the fourth-quarter 24Q annexure. An employee's return is essentially Part B re-stated; discrepancies between the two halves, or between Form 16 and Form 26AS, are what generate notices.
How Form 16 actually gets made
-
1
Deduct correctly all year
Monthly TDS per the Section 192 projection, deposited by the 7th of each following month against the establishment's TAN. Every later artifact is downstream of these deposits.
-
2
File Form 24Q quarterly
Employee-wise deduction detail each quarter; the fourth quarter carries the annual salary annexure — effectively Part B's source. Clean quarterly filings are the whole game.
-
3
Generate Part A from TRACES
After the fourth-quarter return processes, download Part A per employee from TRACES: the government-stamped certificate of what was deposited against each PAN.
-
4
Assemble and reconcile Part B
Prepare the salary annexure per employee (components, exemptions, deductions, computation) and reconcile it against Part A's totals and the year's payslips before anything goes out.
-
5
Issue by the deadline, keep the trail
Deliver both parts (digitally signed is standard) by 15 June, retain copies and the reconciliation, and handle any correction through a revised return, never through an edited PDF.
A worked example
An employee earned ₹9,60,000 gross with ₹78,000 TDS deducted across the year. Part A shows the four quarters' deposits summing to ₹78,000 against her PAN. Part B shows the salary breakup, the standard deduction, her declared deductions per the old regime she elected, taxable income and tax — landing on the same ₹78,000. Her Form 26AS agrees, so her return pre-fills cleanly and files in minutes. Her colleague's Part B, prepared from a spreadsheet that missed a mid-year revision, shows ₹4,000 less than Part A, a mismatch that takes a revised 24Q and two months to unwind. The difference between the two experiences was made monthly, not in June.

Why Form 16 season is a systems test
June exposes the payroll year. Establishments that ran clean months — projections maintained, deposits timely, quarterly returns reconciled — export certificates in an afternoon. Establishments that ran spreadsheets spend June reconstructing: chasing challans, re-deriving exemptions, discovering the March arrears that never reached a return. The test is unforgiving because three parties hold copies of the truth (TRACES, the employer, and the employee's Form 26AS) and any two disagreeing generates work. The only strategy that wins June is boring monthly correctness, which is not a June activity at all.
Form 16 beyond tax: the document's second life
Form 16 doubles as India's de facto income proof — banks underwrite loans on it, embassies read it for visas, landlords ask for it. That second life raises the stakes on accuracy and availability: an employee whose Form 16 understates income by a missed component pays for it in loan eligibility, and one who cannot retrieve older years' certificates pays in paperwork. Employers who keep every year's certificates retrievable through self-service quietly remove an entire category of HR requests, and hand their alumni a reason to speak well of the payroll long after they have left.
Part B under two regimes
Because employees elect regimes individually, one establishment's Form 16 set spans both computations: old-regime certificates carrying HRA exemptions and Chapter VI-A detail, new-regime ones mostly standard deduction on lower slabs. The annexure must reflect each employee's actual election and the deductions actually allowed against proofs, a mixed-regime workforce is precisely where hand-prepared Part Bs drift, and where system-generated ones from per-employee projections hold.
How payroll software applies this
PeopleDeck accumulates Form 16 data as a by-product of every approved run: the projection drives monthly TDS, deposits are tracked against their challans, quarterly 24Q files generate with employee-wise detail, and at year-end Part B assembles from the same records that produced every payslip, so Part A, Part B and the payslips reconcile by construction. Employees receive their certificates through self-service; filings and issuance remain the establishment's acts.

Frequently asked questions
When must Form 16 be issued?
By the currently prescribed annual deadline (15 June following the financial year's end) for every employee who had TDS deducted. Late issue attracts per-day penalties, and practically it delays every employee's return filing, which is the reputational cost.
What if an employee changed jobs mid-year?
Each employer issues Form 16 for their own period; the employee files with both. Where the second employer received Form 12B and consolidated the projection, their Part B reflects the combined computation: one of the strongest arguments for taking 12B seriously at joining.
Does payroll software 'file' Form 16?
No, and be wary of anyone claiming so. Software accumulates the salary-TDS data, prepares the 24Q returns for filing, and assembles Part B; Part A downloads from TRACES after the establishment's returns are processed. Filing returns and issuing the certificate are the employer's acts.
What is the difference between Form 16 and Form 16A?
Form 16 covers salary TDS under Section 192. Form 16A covers TDS on non-salary payments — professional fees, rent, interest. A consultant on a retainer gets 16A, not 16; classifying people correctly upstream decides which certificate they rightly receive.
What should an employee check on receiving Form 16?
PAN correctness first; then that Part A's deposited totals match the payslips' TDS lines and Form 26AS; then Part B's exemptions against what was actually declared and proved. Five minutes of checking prevents the mismatch notices that take months to unwind.
Can a Form 16 be corrected?
Yes — by the employer revising the underlying TDS return and regenerating; there is no shortcut that bypasses the return. Which is the operational lesson: correctness lives in the quarterly filings, and year-end is too late to discover the year.
What if TRACES data and our payroll records disagree?
TRACES reflects what your filed returns claimed and your challans paid, so a disagreement means a return or deposit error, fixed by revising the return, not by editing the certificate. Investigate before June: the mismatch visible in Part A generation was already visible in quarterly processing for whoever looked.
