How to write an offer letter in India.

A practical guide for Indian startup founders — what to include, what to avoid, the laws that apply, and how to get it signed.

Quick answer

An Indian offer letter must include: candidate name, role, compensation in INR, start date, offer expiry, IP assignment, confidentiality, probation and notice period, and governing law. Avoid post-employment non-competes (void under Section 27 ICA) and at-will termination language. Always get a signed copy returned to make it binding.

What is the difference between an offer letter and an appointment letter?

Offer letter
  • ✓Issued before the candidate joins
  • ✓Conditional — void if candidate doesn't accept or join
  • ✓Sets the terms of employment
  • ✓Candidate signs to accept the offer
Appointment letter
  • ✓Issued on or after the joining date
  • ✓Confirms the employment relationship
  • ✓May include additional terms beyond the offer
  • ✓Signed on day one

Most Indian startups send an offer letter pre-joining and issue an appointment letter on day one. Firmly handles the offer letter — the document you send before the candidate walks in the door.

What to include

What must every Indian offer letter include?

1
Candidate name and address
Full legal name and current address. The address matters if you ever need to serve formal notice.
2
Job title and employment type
State the role clearly and specify whether it is full-time employment, an internship, or a contractual engagement. Each type carries different legal obligations.
3
Compensation
Annual CTC or monthly stipend in INR. Break down fixed pay, variable, and any joining bonus. If you're offering ESOPs, include the grant value, vesting schedule, and cliff period.
4
Start date and offer expiry
A start date and an expiry date for the offer. Without an expiry, the candidate can accept months later and you have limited grounds to refuse.
5
IP assignment
Under the Indian Copyright Act, work created by an employee belongs to them by default unless assigned in writing. Include explicit IP assignment and work-for-hire language.
6
Confidentiality
A confidentiality obligation that covers both during and after employment. Post-employment confidentiality — unlike non-competes — is enforceable under Indian contract law.
7
Probation period and notice period
For full-time employees: probation duration, notice period during probation (usually shorter), and notice period after confirmation. This governs how exits work.
8
POSH and DPDP acknowledgement
For companies with 10+ employees, POSH compliance is mandatory. Including a POSH clause and a DPDP Act 2023 data privacy clause shows due diligence and is expected by legal auditors.
9
Governing law and jurisdiction
Specify India and the city where disputes are resolved (typically where the company is registered). Without this, jurisdiction becomes contested.

What to avoid

What offer letter mistakes turn into disputes?

✗
Post-employment non-compete
Section 27 of the Indian Contract Act voids any agreement that restrains someone from exercising a lawful profession after employment. Non-competes are common in US offers — they're largely unenforceable in India. Use non-solicitation and confidentiality instead.
✗
Missing IP assignment
The default position under the Indian Copyright Act is that the creator owns the copyright. If your offer letter doesn't assign IP to the company in writing, your developer's code may legally belong to them — not you.
✗
At-will termination language
Indian courts don't recognise at-will employment for formal employees. Including US-style at-will language creates ambiguity that a wrongful-termination argument can exploit. Use clear probation and notice period terms instead.
✗
Intern offer that looks like an employee offer
If an intern offer letter reads like an employee contract — with PF deductions, standing-orders coverage, and permanent-job framing — a labour audit can reclassify the intern as an employee and backdate PF, ESI, and gratuity liability.
✗
No offer expiry date
Without an expiry, a candidate can accept weeks later when your hiring situation has changed. Adding 'This offer is valid until [date]' gives you a clean way to move on.

The legal context

Which Indian laws apply to offer letters?

Indian Contract Act, 1872
Governs whether an offer letter is a binding contract (it is, once accepted). Also voids post-employment non-competes under Section 27.
Indian Copyright Act, 1957
Work created by employees belongs to them by default — not the employer — unless assigned in writing. This is why IP assignment clauses exist.
Industrial Employment (Standing Orders) Act, 1946
Governs probation, classification of workers, and termination procedures for companies with 50+ workers. Shapes how probation and notice period clauses should be worded.
POSH Act, 2013
Mandatory for companies with 10+ employees. Requiring acknowledgement in the offer letter ensures the employee is aware of the policy from day one.
Digital Personal Data Protection Act, 2023
Governs how personal data of employees and candidates is collected and processed. Including a DPDP clause in offer letters documents the data-processing consent.

FAQ

Common questions

An offer letter is issued before the candidate joins — it's a conditional document that becomes void if the candidate doesn't accept or doesn't join. An appointment letter is issued on or after the joining date and confirms the employment relationship. Both are binding contracts once signed. Most Indian companies use offer letters before joining and issue appointment letters on day one.

To be enforceable as a contract, there must be acceptance — which means the candidate needs to sign and return it. An unsigned offer letter is evidence of your offer but isn't a binding agreement. Always get a signed copy back.

It should be on company letterhead (or include your company name and logo), signed by an authorised signatory, and dated. Plain English is fine — legal jargon is not required. What matters is that the key terms are specific: role, compensation, start date, notice period, IP assignment.

If the offer includes an expiry date and the candidate doesn't accept by that date, the offer lapses. If there's no expiry and the candidate accepts late, you're in a grey zone — it's advisable to confirm in writing whether the offer is still open rather than relying on the original document.

Under the Indian Contract Act, an offer can be revoked at any time before it is accepted. Once the candidate signs and returns the letter, it becomes a binding contract and revocation is much harder — potential damages or reputational exposure. Revoke early if circumstances change.

For standard startup hires, no — Firmly handles every item in this guide by default. IP assignment, confidentiality, probation, POSH, DPDP, and governing law are all included.
