An offer letter looks simple — a job title, a salary figure, a joining date — but it's the document that actually sets the terms of an employment relationship before either side has fully committed to it. Get it wrong, and a company can face a candidate who accepted based on promises the final contract doesn't honour, or worse, an offer that turns out to be structured against rules that changed under India's new labour law framework. This guide covers what an offer letter needs to include, how it differs legally from an appointment letter, and a set of genuinely new requirements that took effect under India's overhauled labour codes.
An offer letter is a formal document issued by an employer to a selected candidate, setting out the key terms of the employment being offered — job title, reporting structure, compensation, joining date, and the conditions under which the offer is made. It's typically issued after interviews are complete and before the candidate formally joins, and it functions as the employer's documented offer under contract law: something the candidate can accept, reject, or negotiate.
It's distinct from an appointment letter, which is issued once the candidate has actually joined and confirms the employment relationship has formally begun, and from a full employment contract or agreement, which typically contains more detailed terms — confidentiality, non-compete, IP assignment, and dispute resolution clauses — beyond what an offer letter usually covers.
An offer letter operates under the same basic principles as any contract under the Indian Contract Act, 1872: an offer, once accepted, creates binding obligations on both parties, provided the other ingredients of a valid contract (competent parties, lawful consideration, free consent) are present. So while an offer letter is often described loosely as "not legally binding," that's only accurate up to the point of acceptance — once a candidate accepts the terms in writing (commonly by countersigning or replying in acceptance), the offer letter becomes an enforceable statement of the terms both sides agreed to, even before a separate, more detailed employment contract is signed.
This matters in practice more than people often assume. A candidate who resigns from their current job and makes relocation or financial decisions based on an accepted offer letter has a real basis to claim damages if the employer withdraws the offer without a valid reason specified in the letter itself — which is exactly why the conditions under which an offer can be withdrawn should be spelled out clearly in the document, not left implied.
This is the most significant recent development affecting offer and appointment letter practice in India, and it changes what was previously good HR practice into an actual statutory requirement.
India's four Labour Codes — the Code on Wages, 2019, the Industrial Relations Code, 2020, the Code on Social Security, 2020, and the Occupational Safety, Health and Working Conditions Code, 2020 — consolidate 29 older central labour laws, some dating back to before Independence, into a unified framework. After years of delay, the government notified their implementation with effect from 21 November 2025.
Among the changes with the most direct, everyday relevance to hiring: every employer is now required to issue a written appointment letter to every worker, across organised, unorganised, and even gig and platform work arrangements — the codes formally define "gig worker" and "platform worker" for the first time, extending statutory coverage to categories of work that previously sat outside the formal appointment-letter framework entirely. This is a marked shift from the earlier position, where issuing an appointment letter was standard corporate practice for salaried employees but wasn't itself a universal legal mandate across all categories of work.
Central Rules under the Code on Wages were formally notified in May 2026, and state governments have been progressively notifying their own corresponding rules through 2026 — meaning the practical compliance mechanics are still being finalised in some states even as the core obligation itself is already in force. Employers relying on offer letter or appointment letter templates drafted before November 2025 should treat them as due for review, not as still current.
Beyond the standard commercial terms, a few elements are worth building into offer letters now specifically because of the Labour Code changes:
This is a genuinely significant technical change, and it directly affects how the compensation section of an offer letter should be drafted.
Under the Code on Wages, the definition of "wages" has been standardised across all four codes, and it now requires that basic pay plus dearness allowance make up at least 50% of an employee's total remuneration. Where the combined value of excluded components — HRA, conveyance allowance, overtime, special allowances, and similar items — exceeds 50% of total pay, the excess is legally treated as "wages" for the purpose of calculating Provident Fund contributions, gratuity, bonus, and other wage-linked statutory dues, regardless of what the pay slip labels it as.
This reverses a long-standing, widely used industry practice of keeping basic pay artificially low (often 30–40% of CTC) and loading compensation into allowances specifically to minimise the PF and gratuity base. Under the current framework, that structure no longer reduces statutory liability the way it used to — the excess allowance amount gets reclassified as wages regardless of the label used in the offer letter.
Practically, this means:
Generally, yes, if it's withdrawn before the candidate accepts it — an unaccepted offer creates no binding obligation on either side under ordinary contract law principles. Once accepted, withdrawal becomes considerably riskier: if the offer letter doesn't specify conditions under which it can be revoked (a background check turning up a disqualifying issue, for instance, or a specific joining deadline that passes), an employer withdrawing an accepted offer without cause can face a legitimate claim for damages, particularly where the candidate has taken demonstrable action in reliance on it — resigning from a current job being the most common example. This is exactly why a well-drafted offer letter should state clearly what conditions the offer is subject to, rather than leaving them implied.
Probation periods and notice periods are standard, enforceable terms in Indian employment offers, provided they're reasonable and clearly stated. Non-compete clauses restricting what an employee can do after leaving the company sit on much shakier legal ground — Section 27 of the Indian Contract Act, 1872 voids agreements that restrain a person from exercising a lawful profession, trade, or business, and Indian courts have consistently struck down post-employment non-compete clauses as unenforceable, even where they're framed as reasonable in scope or duration. A confidentiality clause protecting the employer's specific proprietary information, however, is generally enforceable and serves a similar protective purpose without running into the same restraint-of-trade problem — offer letters looking to protect sensitive business information are better served by a well-scoped confidentiality clause than an unenforceable non-compete.
Offer letter drafting isn't just about wording a job description well — since November 2025, it means aligning compensation structures with the new 50% wage rule, ensuring the appointment letter obligation is properly built into your hiring workflow, and drafting revocation and confidentiality terms that will actually hold up rather than create risk later. Our team at LegalDev drafts and reviews offer letters that reflect the current Labour Code requirements, helps restructure CTC breakdowns to stay compliant, and prepares the appointment letters and employment agreements that follow — so your hiring paperwork is accurate from the first document a candidate sees.

An offer letter is a formal document an employer issues to a selected candidate, setting out the key terms of the job being offered — title, compensation, joining date, and conditions — before the candidate formally joins the organisation.
Not until the candidate accepts it, but once accepted, it becomes an enforceable statement of the agreed terms under the Indian Contract Act, 1872, even before a more detailed employment contract is signed.
Yes. Under India's four Labour Codes, effective from 21 November 2025, employers are required to issue a written appointment letter to every worker, including gig and platform workers, which were formally defined under the codes for the first time. This is a new statutory obligation, not just a recommended HR practice.
Under the Code on Wages, basic pay plus dearness allowance must make up at least 50% of an employee's total remuneration; if excluded allowances collectively exceed 50%, the excess is treated as wages for PF, gratuity, and bonus calculations regardless of what it's labelled as in the offer letter. Offer letters issued today should reflect compensation structures built around this threshold.
It's legally riskier once accepted, particularly if the candidate has relied on it — for example, by resigning from a previous job. A well-drafted offer letter should clearly state the conditions under which the offer can be revoked, to avoid disputes if withdrawal becomes necessary.
Generally not, if it restricts the employee's ability to work after leaving the company. Section 27 of the Indian Contract Act, 1872 voids agreements restraining a lawful profession, trade, or business, and courts have consistently struck down post-employment non-compete clauses. A properly scoped confidentiality clause is a more enforceable way to protect sensitive business information.
An offer letter is issued after selection and before joining, and sets out the terms of the offer. An appointment letter is issued on or around the joining date and formally confirms the employment relationship has begun — and is now a mandatory document under the Labour Codes for every category of worker.
Yes. India's Labour Codes formally defined "gig worker" and "platform worker" for the first time and extended the appointment letter requirement and social security coverage to these categories, which previously sat largely outside the formal documentation framework that applied to salaried employees.
