Offer letter vs appointment letter: what each must include

An offer letter is a conditional proposal of employment sent before joining: it states the role, CTC, joining date and conditions, and the candidate accepts it. An appointment letter is issued at joining and sets out the full terms of employment, including probation, notice, leave, conduct and termination. In India the Occupational Safety, Health and Working Conditions Code, 2020 requires employers to issue a letter of appointment to every employee.

This guide explains what each letter must contain and how to draft them. For the wider joining process, see our employee onboarding checklist.

Offer letter vs appointment letter: the key differences

Point	Offer letter	Appointment letter
Purpose	Proposes employment and records the headline terms	Confirms employment and records the full terms and conditions
Timing	After selection, before joining	On joining, or before the employee starts work
Nature	Conditional; can be withdrawn if conditions are not met	The working contract of employment, read with company policies
Length	One to three pages plus a CTC annexure	Several pages, often with annexures and policy references
Statutory basis	Not separately prescribed	Required under the OSH Code, in the form prescribed by the rules
Acceptance	Candidate accepts within the validity period	Employee signs a copy to acknowledge the terms

Some companies combine the two into a single detailed offer cum appointment letter. That is workable, provided the combined letter contains everything the appointment letter must, and is issued before the person starts work.

What the law says about appointment letters

Section 6(1)(f) of the OSH Code requires an employer to issue a letter of appointment to every employee on appointment, with the information and in the form prescribed by the appropriate government's rules. For employees already in service when the Code came into force on 21 November 2025, the Code provides a period for issuing the letter to existing staff; check the exact timeline in the Code and your state's rules.

The prescribed form typically asks for details such as the employee's name, designation, category of employment, date of joining and wages. State rules under the Labour Codes are being notified progressively, so confirm the form that applies to each location. The Codes and central rules are on the Ministry of Labour and Employment website. Where an establishment has certified standing orders, the appointment terms should be consistent with them.

What an offer letter must include

• Designation, grade and department.
• Reporting manager, by role if not by name.
• CTC, with the fixed and variable split, and a component-wise breakup as an annexure.
• Joining date, and what happens if the candidate cannot join on that date.
• Work location, and whether transfer is possible.
• Offer validity, the date by which the candidate must accept.
• Conditions, such as satisfactory background verification, submission of documents, medical fitness where relevant, and relieving from the previous employer.
• Probation and notice, in summary, with a note that full terms will follow in the appointment letter.
• Acceptance block, for signature and date.

Worked example: a CTC annexure that adds up

The CTC annexure is where offers most often go wrong. Here is a CTC of ₹10,20,000, with PF on the ₹25,000 ceiling (the PF wage ceiling from 17 September 2026) and gratuity provided at 4.81% of Basic.

Component	Monthly	Annual
Basic	₹30,000	₹3,60,000
HRA (50% of Basic)	₹15,000	₹1,80,000
Special allowance	₹25,557	₹3,06,684
Gross salary	₹70,557	₹8,46,684
Employer PF (12% of ₹25,000)	₹3,000	₹36,000
Gratuity provision (4.81% of Basic)	₹1,443	₹17,316
Fixed CTC	₹75,000	₹9,00,000
Annual variable pay at target		₹1,20,000
Total CTC		₹10,20,000

Check: ₹3,60,000 + ₹1,80,000 + ₹3,06,684 = ₹8,46,684 gross; plus ₹36,000 + ₹17,316 = ₹9,00,000 fixed; plus ₹1,20,000 variable = ₹10,20,000. Monthly: ₹30,000 + ₹15,000 + ₹25,557 + ₹3,000 + ₹1,443 = ₹75,000, and ₹75,000 x 12 = ₹9,00,000.

State that variable pay depends on performance and plan rules, and that statutory deductions (employee PF, PT, TDS and ESI where applicable) come out of gross. Under the Labour Codes, the wage base for PF and gratuity follows the wage definition and its 50% rule; see our guide to the Labour Code wage definition before you finalise structures. For how each component works, see salary structure and CTC breakup.

Are non-compete clauses enforceable in India?

Section 27 of the Indian Contract Act, 1872 provides that an agreement restraining anyone from exercising a lawful profession, trade or business is void to that extent. The only express exception relates to the sale of goodwill. Courts have generally applied this to hold that restraints operating after employment ends, such as "you will not join a competitor for 12 months", are not enforceable against an employee. The Act is published on the India Code portal.

Restrictions during employment are treated differently. A clause requiring the employee to work only for the employer while employed is generally viewed as part of the employment bargain rather than a restraint of trade. Confidentiality clauses that protect genuine trade secrets, and non-solicitation clauses, are assessed on their facts and wording, and their enforceability is not guaranteed. Draft these clauses narrowly and take legal advice; do not rely on a post-employment non-compete as your main protection.

Sample clause snippets

These are illustrations to adapt with your legal adviser, not ready-to-use terms.

• Offer validity: "This offer is valid until 20 October 2026. If we do not receive your signed acceptance by that date, the offer will lapse."
• Conditional offer: "This offer is conditional on satisfactory verification of your education, employment history and identity, and on submission of the documents listed in Annexure B."
• Probation: "You will be on probation for six months from your date of joining. The company may extend probation once, by up to three months, by written notice before it ends. Your confirmation will be communicated in writing."
• Notice: "After confirmation, either party may end employment by giving 60 days' written notice, or salary in lieu of the notice period not served, subject to the company's notice period policy."
• Confidentiality: "You will not disclose or use confidential information of the company except as required for your duties, during or after your employment."
• Exclusivity: "While employed, you will not take up any other employment, consultancy or business without the company's prior written consent."

Digital signing and acceptance tracking

Electronic signatures and online acceptance are widely used for offer and appointment letters. Whatever the method, keep:

• The exact version of the letter the candidate accepted, with a timestamp.
• A record of who issued it and who approved the compensation.
• A tamper-evident copy, so that the letter on file is provably the one that was signed.
• An expiry date on the offer, with reminders before it lapses.

Track acceptance against joining. An accepted offer that goes quiet near the joining date is the clearest early warning of a dropout; see our guide to reducing offer dropouts.

Common mistakes

• A CTC annexure that does not add up to the CTC in the letter.
• Promising a joining bonus or relocation support without stating the clawback terms.
• No offer validity date, so a candidate accepts weeks later.
• Issuing the appointment letter months after joining, or not at all.
• Probation and notice terms in the offer that differ from the appointment letter.
• Relying on a post-employment non-compete instead of strong confidentiality and access controls.
• Copying a template from another company with the wrong entity name or state.

FAQs

What is the difference between an offer letter and an appointment letter? The offer letter is a conditional proposal before joining with headline terms. The appointment letter is issued at joining and contains the full terms and conditions of employment.

Is an appointment letter mandatory in India? Yes. The OSH Code, 2020 requires employers to issue a letter of appointment to every employee, in the form prescribed under the rules. Confirm the format for your state.

Can a company withdraw an offer letter? An offer can usually be withdrawn before acceptance, or if a stated condition such as background verification is not met. Withdrawing an accepted offer without cause can create legal exposure, so take advice.

Is a non-compete clause valid in India? Post-employment non-compete clauses are generally unenforceable under Section 27 of the Indian Contract Act, 1872. Restrictions during employment, confidentiality and non-solicitation clauses are treated differently.

Can offer and appointment letters be signed digitally? Electronic acceptance and signatures are commonly used. Keep the signed version, a timestamp and a tamper-evident copy on file.
