Rule 306 of the Income-tax Rules, 2026

Rule 306 — Initial contributions. Made under s.29 of the Income-tax Act, 2025.

Where this rule sits

Rule 306 gives effect to Section 29 of the Income-tax Act, 2025. A rule cannot go beyond the section it serves: where the two seem to differ, the section governs.

← Rule 305  ·  Rule 307 →

What this rule does

The rule limits the initial contribution of an employer to a superannuation fund for the past services of an employee, for the purposes of the deduction allowable under section 29(1)(a) and subject to any condition the Board may think fit to specify. That contribution shall not exceed the total of 27% of the salary of the employee for each year of past service, as reduced by the contributions of the employer to a provident fund, whether recognised or unrecognised, for the same employee for each such year.

Why it is there

An initial contribution for past service is a lump sum that can cover many years at once, so without a limit the deduction under section 29(1)(a) could be made as large as the employer chose. The rule caps it by reference to the employee's salary for each year of past service, and then subtracts what the employer has already put into a provident fund for the same employee for those years, so that the same past service is not funded twice at the revenue's cost.

The figures, and what each one turns on

Read the condition in the same row. A figure quoted without it is a wrong answer with a citation attached.

Ceiling on the initial contribution for past servicesNot exceeding the total of 27% of the salary of the employee for each year of past serviceReduced by the employer's contributions to a provident fund, recognised or unrecognised, for the same employee for each such year; this is an upper limit, not a prescribed amountRule 306
Further conditionsAny condition which the Board may think fit to specifyThe rule states no such conditions of its own; the deduction is subject to those the Board specifiesRule 306

What this means in practice

The 27% figure is a ceiling on what may be contributed, not a rate at which a contribution is to be made, and it is computed year by year over the period of past service before the years are totalled. The subtraction is mandatory and takes in provident fund contributions whether the fund is recognised or unrecognised, so an employer who has funded a provident fund throughout the past service may find the permitted initial contribution much reduced or exhausted. The rule also leaves room for further conditions the Board may specify, which the rule itself does not state. It governs the amount that may be contributed for the purposes of the deduction; the deduction itself is given by section 29(1)(a).

An example

Illustrative only, and invented for this page. The figures are chosen to show the requirement biting, not taken from any real matter.

An employer sets up a superannuation fund and wants to fund ten years of an employee's past service. Taking 27% of the employee's salary for each of those ten years gives Rs. 18,00,000. The employer had contributed Rs. 6,00,000 to a provident fund for the same employee over those years, so the initial contribution is limited to Rs. 12,00,000, and the deduction under section 29(1)(a) cannot be built on any larger figure.

Where you meet this rule

In the computation of the deduction claimed for an initial contribution to a superannuation fund in the year the fund is set up or an employee's past service is funded, and in any examination of that claim.

The words themselves

the initial contribution of the employer to a superannuation fund for the past services of an employee shall not exceed the total of 27% of the salary of the employee for each year of past service, as reduced by the contributions of the employer to a provident fund (recognised or unrecognised), if any, for the same employee for each such year

What people get wrong

What this page does not tell you. It does not reproduce the rule. Everything above was written from the rule’s own text as the Income Tax Department publishes it — the text is here. A rule is subordinate legislation: it prescribes the method, the form or the period, and it cannot enlarge the charge the section imposes. Where a figure matters, read the sub-rule it comes from.
