What the letter should contain
| Element | Why |
|---|---|
| Review period covered | Distinguishes this cycle from the last and anchors the assessment |
| Rating or outcome | The employee's record of what was decided |
| Revised structure, component by component | Components drive contributions, tax and every later computation |
| Effective date | Determines arrears, contribution recomputation and the tax year |
| Arrears treatment | Whether the difference is paid in one cycle or applied to the original months |
| Change in designation or grade | If any, along with any change in reporting line |
| Change in other terms | Notice period, variable pay eligibility, or benefits, if these move with the grade |
| Variable pay terms | Target, weighting and the period it applies to, if applicable |
Issuing only a revised cost to company figure is the common shortcut, and it produces the recurring problem: the employee cannot check their own payslip against the letter, and payroll ends up explaining the difference between a headline figure and a monthly net every year.
Effective date, arrears and the tax consequence
Indian appraisal cycles commonly run to a financial year starting in April, with letters issued in June or July and revisions effective retrospectively. That gap has consequences the letter should deal with explicitly.
- Arrears for the intervening months are payable, and the letter should say when. An unstated payment date produces queries from every recipient in the same week.
- Decide whether arrears are applied to their original months or paid in the current cycle. The choice affects the period the amount is attributed to for contribution computations and the tax year it falls in, and it should be a recorded decision rather than a system default.
- Provident fund and other contributions on the revised wages for the retrospective period have to be computed and remitted, not just the salary difference.
- Tax deducted at source for the year should be recomputed on the revised annual figure, so the remaining months absorb the change rather than leaving a shortfall in March.
- Where an employee resigned between the effective date and the issue date, the position on their arrears and their eligibility should be settled by policy rather than case by case.
Wording that commits you
- Avoid future promises. A line saying the position will be reviewed again in six months, or that a promotion will follow on completion of a project, is read as a commitment and produces a grievance when it does not happen.
- Be careful with performance-linked language. Describing a payout as assured, or as part of the salary, can make a variable component something you must pay regardless of outcome.
- State discretion where it exists, and then exercise it consistently. A reserved discretion applied differently to two similar cases is what a grievance is built on.
- Do not use the letter to introduce unrelated changes, such as a longer notice period or a new restrictive covenant, buried among the numbers. A change to terms should be visible and agreed.
- Keep it consistent with the appointment letter and the policy. Where three documents say different things about notice or variable pay, the employee will rely on the most favourable.
- Where the outcome is no increase, say so in writing with the reason. Employees who receive nothing and hear nothing assume they were overlooked, and the assumption is usually more damaging than the decision.
Issuing and recording
- Issue every letter in the same cycle. Staggered issue is read, correctly, as a signal about who mattered.
- Have the manager deliver the outcome in conversation before the letter arrives. A letter that is the first the employee hears of their rating turns a decision into an ambush.
- Record acknowledgement, and keep the version issued. Where a revision is later disputed, the document actually given to that person is what matters, not the template.
- Make sure payroll and the letter come from the same source of truth. A structure typed into a letter and separately keyed into payroll will differ for somebody.
- Keep the assessment behind the rating, not only the outcome. Where a rating drives a payout or a later decision, the record of how it was reached is what defends it.
- Check the aggregate before issuing anything. A distribution of ratings that differs sharply by gender or by location within the same role is worth examining before the letters go out rather than after.

What the Code on Wages, 2019 replaced
4 enactments stand repealed under s. 69, in force 21 November 2025 by S.O. 5322(E).
- Payment of Wages Act, 1936
- Minimum Wages Act, 1948
- Payment of Bonus Act, 1965
- Equal Remuneration Act, 1976
Across all four labour Codes, 29 enactments stand repealed. A policy or handbook that still cites one of them by name is describing rules that no longer exist.
Statutory reference
- Act
- Code on Wages, 2019
- Section
- Code on Wages, 2019: the definition of wages, its exclusions and the one-half proportion rule at the first proviso to section 2(y), which determine the effect of a revised salary structure on statutory computations; the requirement to maintain registers of wages and issue wage slips reflecting the revised structure. Code on Social Security, 2020: contribution bases for provident fund and insurance and the computation base for gratuity, which follow the definition of wages, and the recomputation required where a revision is retrospective. Income-tax Act, 2025, Section 392 (deduction from salary at the average rate on the estimated income for the year, which is what requires the liability to be recomputed across the remaining months when a revision is retrospective). No counterpart has been located in the Income-tax Act, 2025, so no relief is asserted here. Indian Contract Act, 1872: under Section 62 a contract is altered only by agreement of the parties, and under Section 25 a promise without consideration is void unless it falls within one of three savings, none of which covers an appraisal letter. In force 21 November 2025 for the Codes
- Key limits
- A retrospective revision requires contributions on the revised wages for the intervening period, not only payment of the salary difference. An appraisal letter is not by itself a variation of the contract, since Section 62 requires agreement of the parties. Verify the wage definition and its effect on the contribution and gratuity base, and the tax treatment of arrears, before issuing revised structures. That Act was repealed with effect from 1 April 2026.
Frequently asked questions
What should an appraisal letter contain?
The review period, the outcome or rating, the revised structure component by component, the effective date, how arrears will be paid, and any change in designation, grade or other terms. A single cost to company figure is not enough for the employee to check anything against.
How are arrears handled when a revision is retrospective?
The salary difference is paid, and contributions on the revised wages for the intervening period have to be computed and remitted as well. Whether arrears are applied to the original months or paid in the current cycle affects the attribution and should be a recorded decision.
Does an appraisal letter change the employment contract?
Yes, it varies the terms, which is why the wording matters as much as the number. A promise recorded in it, such as a further review in six months, is capable of being held to whether or not it was intended as a commitment.
Should we issue a letter to someone getting no increase?
Yes, with the reason. Employees who receive nothing and hear nothing conclude they were overlooked, and that assumption usually does more damage than the decision itself.
When should the letter be issued relative to the conversation?
After it. The manager should deliver the outcome in conversation first, because a letter that is the first the employee hears of their rating converts a decision into an ambush and guarantees the discussion happens on the worst possible terms.
How Engage issues appraisal letters
Engage generates the letter from the same revised structure that goes into payroll, so the components in the document and the components in the payslip cannot diverge. The effective date drives the arrears computation and the contribution recomputation for the retrospective period, and the issued version is retained against the employee record with its acknowledgement.
