Appointment Letters Are Now Mandatory in India — Most SMBs Aren't Compliant Yet
Since 21 November 2025, issuing a written appointment letter to every employee isn't a courtesy anymore — it's the law. India's four Labour Codes, which came into force that day, require every employer, right down to a 15-person startup, to give every employee a formal appointment letter covering their job details, wages, and social security coverage. If a recent HR audit turned up employees at your company who never got one, they're not unusual. They're just non-compliant.
For years, a written appointment letter was something only larger, more process-heavy Indian companies bothered with consistently. Plenty of 10–150-employee tech firms ran on a signed offer letter, a verbal confirmation from the founder, and not much else on paper. That gap is exactly what the new rule closes — and it closes it retroactively, not just for new hires.
What actually changed
Before the Labour Codes, there was no single central requirement forcing every employer to issue an appointment letter. Larger, unionised, or factory-registered employers often had one anyway, driven by sector-specific Standing Orders. Everyone else treated it as good practice, not law.
The Labour Codes remove that gap. Every employer, across every sector and headcount band, now has to issue a written appointment letter to every employee — not just to whoever asks for one, and not just to new joiners going forward.
> An offer letter is a promise. An appointment letter is a record — and as of late 2025, a legal one your company is required to keep.
What the letter has to cover
The requirement itself is broad rather than a rigid template: every appointment letter must state the employee's job details, their wages, and their social security coverage. In practice, for an Indian tech company, that means the letter should clearly lay out:
- Designation and reporting structure
- Work location
- Wage structure — Basic Pay, HRA, and other components, not just a single CTC number
- Applicable social security coverage (PF and ESI enrollment, where they apply)
- Probation duration and the notice period during and after confirmation
That last point is where a lot of appointment letters written before this rule fall short. A one-line "you're hired at ₹X CTC" letter satisfies neither the spirit nor, arguably, the letter of "job details, wages, and social security" — a wage number alone isn't a wage structure, and it says nothing about social security enrollment at all.
The deadline for employees you already have
This is the part most HR teams miss: the requirement isn't limited to people who join after 21 November 2025. Guidance following the Labour Codes points to a three-month window for issuing appointment letters to employees who were already on the payroll and had never been given one. If your company has been operating on offer letters and verbal terms for existing staff, the clock on fixing that started the day the Codes took effect — not the day you happen to notice the gap.
Offer letter vs. appointment letter vs. relieving letter
These three documents get confused constantly, and now that one of them is a legal requirement, the mix-up is worth clearing up properly.
| Document | Issued when | Binding? | Core purpose |
|---|---|---|---|
| Offer letter | Before joining | Not fully — a candidate can still negotiate or decline | Proposes role, CTC, and joining date |
| Appointment letter | On or around the joining date, after acceptance | Yes — the formal employment contract | Confirms designation, wage structure, social security, probation, and notice terms |
| Relieving letter | On or after the last working day | Confirms release, not new terms | States the resignation was accepted and dues/duties are settled |
Only the middle one is what the Labour Codes now mandate. An offer letter, however detailed, doesn't satisfy the requirement — it's issued before the employment relationship exists, and it's usually still negotiable at that stage.
What to actually do about it
For a 10–150-employee tech company, catching up doesn't need a legal overhaul. It needs three concrete things:
1. Audit who's missing one. Pull your employee list and check who has a signed appointment letter on file — not an offer letter, not an email thread, an actual appointment letter.
2. Standardise the format once. Build a template that covers designation, wage structure, social security, probation, and notice terms, so every letter going forward is consistent without HR rewriting it from scratch each time.
3. Backfill existing employees inside the window. For anyone missing one, issue a dated appointment letter now rather than waiting for an audit to force the issue later.
We built a free [appointment letter generator] that covers exactly this format — designation, reporting manager, wage structure split into Basic/HRA/Special Allowance, probation duration, and separate notice periods for during and after probation — so a founder or a one-person HR team can generate a compliant letter in a couple of minutes instead of starting from a blank document. It's a starter draft, not a substitute for legal review, but it gets the structure right.
Inside Clan, the same designation, wage structure, and joining date entered once carry through to every payslip automatically — so the record the appointment letter creates doesn't have to be re-typed into payroll separately, and doesn't drift out of sync with it over time. See [Clan's HR and payroll plans] for how that record flows from onboarding through to every monthly run.
The bottom line
This isn't a compliance nice-to-have with a vague enforcement horizon — it's a rule that took effect on a specific date, with a specific catch-up window for people you already employ. If your company has been running on offer letters and good intentions, the fix is a straightforward documentation exercise, not a legal minefield. Treat it as one, close the gap this quarter, and move on — this doesn't replace a labour lawyer's sign-off on your specific company's exposure, but it's enough to know exactly what you're missing and why.
