Invalid pension

Invalid pension is paid when a medical board certifies a central government employee permanently unfit for service. Rule 39%, 50%, no 10-year bar.

Updated 18 August 2026

Invalid pension is the pension granted to a central government civil employee who is retired from service because a medical board certifies a permanent bodily or mental infirmity that makes them unfit to continue, under Rule 39 of the CCS (Pension) Rules, 2021. It is computed exactly like a superannuation pension, 50% of emoluments under Rule 44, and its defining feature is that the usual 10-year qualifying-service requirement is waived, so an employee invalidated early in a career is not left without a pension.

The word “invalid” here is the old administrative sense of being invalided out, that is retired on medical grounds, not a judgment about the person. What matters is a single medical finding: that the employee is permanently incapacitated for the service, or for the particular post held. The cause of the infirmity is irrelevant to the invalid pension. If the infirmity is instead attributable to or aggravated by service, the employee gets the more generous disability pension under the extraordinary-pension rules, not the ordinary invalid pension, and that separate route is covered in its own article.

This article deals only with the ordinary invalid pension: what triggers it, the medical board and the invalidation procedure, how the amount is worked out, the qualifying-service waiver that sets it apart, the service-gratuity fallback where the conditions are not met, a worked example, its treatment for employees on the National Pension System and the Unified Pension Scheme, and the tax position that civil employees most often get wrong. For the framework of civil pensions generally, see the central government pension article.

What triggers an invalid pension

An invalid pension is granted when an employee is compelled to retire because a bodily or mental infirmity permanently incapacitates them for the service, or for the particular post they hold. The trigger is the incapacity being permanent and disabling, certified by the prescribed medical authority. A temporary illness, however serious, does not lead to invalidation; the employee is placed on the appropriate leave and returns to duty on recovery. Invalidation is reserved for the case where recovery to a fit-for-service state is not expected.

The infirmity can be physical or mental, and it can be one that arose entirely outside service, a chronic disease, an accident away from work, or a progressive condition. None of that matters to eligibility for the invalid pension, because the invalid pension asks only whether the employee can still serve, not why they cannot. This is the point that separates it from the disability pension, which asks the opposite question, whether the harm came from the service.

The rule also distinguishes incapacity for the service from incapacity for the post. An employee unfit for their present post but fit for some other work the department can offer is not automatically invalidated; the medical and administrative process considers whether a suitable alternative exists before pensioning the person off.

The medical board and the invalidation procedure

An invalid pension case turns on a medical certification, and the rules build safeguards around it so that neither the employee nor the department can force the outcome informally.

The employee applies to retire, or is proposed for retirement, on the ground of the infirmity, and is referred to the authority Rule 39(3) prescribes: a Medical Board for a gazetted government servant and for a non-gazetted government servant whose pay under Fundamental Rule 9(21) exceeds Rs. 54,000 a month, and a Civil Surgeon, District Medical Officer or Medical Officer of equivalent status in every other case. The rules carry two protections worth naming. Rule 39(6) provides that no medical certificate of incapacity may be granted unless the medical authority has received a request from the head of office or head of department for the examination, so an employee cannot obtain a certificate privately and present it as the basis for invalidation, and no invalidation can be arranged without the employer on record. And where a woman is being examined, Rule 39(7) requires a lady doctor on the board. The board records not just that the employee is unfit but the nature of the infirmity and, where it can, whether the person is fit for any less strenuous work.

That last finding matters, because the board is not limited to a simple fit-or-unfit verdict. If the board reports the employee fit for some less laborious service rather than wholly incapacitated, the department may decline invalidation and instead retain or re-employ the person on a lower post they are able to perform. Invalidation, and the invalid pension that follows, is for genuine permanent incapacity for the service, not for an incapacity for the current post where a suitable alternative exists. An employee who is willing to accept a lower post keeps a salary and continues to earn service, which is often better than being pensioned off at 50%.

Once invalidation is accepted, the head of office processes the pension case in the ordinary way, assessing the emoluments and working out the pension and gratuity, and the case flows to the Accounts Officer for the issue of the Pension Payment Order through the Bhavishya portal, the online pension-processing system that the Department of Pension and Pensioners’ Welfare runs.

How the amount is worked out

The invalid pension is computed exactly like a superannuation pension. It is 50% of emoluments, meaning the last basic pay, or the average emoluments of the last 10 months, whichever is more beneficial, under Rule 44 of the 2021 Rules. It is subject to a minimum of Rs. 9,000 a month and a maximum of Rs. 1,25,000 a month, which is half of the highest pay of Rs. 2,50,000, with dearness relief on top at the current rate of 60% from 1 January 2026.

Two features of the modern rule help the person invalidated with short service. First, since 1 January 2006 there is no proportionate reduction of the pension for service short of the full 33 years; the 50% is a flat figure for anyone who clears the qualifying threshold, as the central government pension calculation article sets out. Second, and more important for invalid pension, that qualifying threshold itself is waived, which the next section covers.

The “more beneficial of last-drawn and 10-month average” rule protects an employee whose pay dipped in the last few months, for instance on reversion from a higher post, so the pension is worked on whichever figure is larger. An invalid pensioner can also commute up to 40% of the pension for a tax-free lump sum under the CCS (Commutation of Pension) Rules 1981, subject to medical clearance, on the same terms as any other pensioner, and the commutation of pension article carries that computation.

The qualifying-service waiver

The standout feature of invalid pension is the waiver of the minimum qualifying service. Ordinarily a central government pension needs at least 10 years of qualifying service; below that, a retiring employee gets only a service gratuity, not a monthly pension. For invalid pension, that 10-year bar is expressly set aside.

Under the proviso to Rule 44(1), an employee who retires on invalidation under Rule 39 before completing 10 years of qualifying service, but who fulfils the conditions in Rule 39(9), is still eligible for the invalid pension at 50% of emoluments, and the 10-year condition does not apply. So an employee invalidated after, say, six years of service is not thrown back on a small gratuity; they draw a full 50% invalid pension, floored at Rs. 9,000 a month plus dearness relief, for life. This is the single most valuable feature of the invalid-pension route, and it is why the correct classification of a medical retirement as invalidation, rather than an ordinary short-service exit, can be worth a monthly pension for decades.

Where the Rule 39(9) conditions are not met, the employee is not left with nothing, which the next section covers.

The service-gratuity fallback and the retirement gratuity

Where the conditions for the invalid pension are not satisfied, Rule 44(2) grants a service gratuity in place of a pension. The service gratuity is half a month’s emoluments for each completed six-monthly period of qualifying service, paid as a one-time lump sum rather than a monthly pension. It is the same fallback that applies to any employee who leaves with less than the qualifying service, and it ensures a medical exit is never empty-handed even where the pension conditions fail.

Separately, and in addition to whichever of the invalid pension or the service gratuity is payable, the retirement gratuity under the general rules is paid. That gratuity is one-fourth of emoluments, basic pay plus dearness allowance, for each completed six-monthly period of qualifying service, up to a maximum of 16.5 times emoluments, and the ceiling was raised to Rs. 25 lakh from 1 January 2024, as the gratuity for central government employees article sets out. The retirement gratuity is a separate benefit from the service gratuity and can be paid alongside the invalid pension, so an invalidated employee typically receives the monthly invalid pension and the lump-sum retirement gratuity together.

Leave encashment is the third terminal payment on a medical exit, and it has its own rule. Rule 39-B(1) of the CCS (Leave) Rules, 1972 grants a servant declared by a medical authority to be completely and permanently incapacitated the cash equivalent of both earned leave and half pay leave at credit on the date of invalidation, up to 300 days, computed as under Rule 39(2). Rule 39-B(2) carries a restriction that is easily missed: a servant not in permanent or quasi-permanent employ receives no cash equivalent for the half pay leave at credit, only for the earned leave.

A worked example

Take an employee with a last basic pay of Rs. 44,900 (Level 6 of the pay matrix), invalidated after eight years of qualifying service, whose conditions under Rule 39(9) are met.

Item	Amount (Rs.)	Basis
Emoluments (last basic pay)	44,900	Higher of last pay and 10-month average
Invalid pension	22,450	50% of emoluments, Rule 44
Dearness relief at 60%	13,470	On the full basic pension, from 1 January 2026
Monthly pension plus relief	35,920	Invalid pension plus dearness relief

The 10-year qualifying-service bar does not apply, so the eight-year service does not cut the pension: it is a flat 50%. The Rs. 22,450 is above the Rs. 9,000 floor, so the floor does not bite. On top of this monthly figure, the employee receives the retirement gratuity as a lump sum: for eight years, that is 16 six-monthly periods, so one-fourth of emoluments times 16, worked on basic pay plus dearness allowance, subject to the Rs. 25 lakh ceiling. Had the same employee failed the Rule 39(9) conditions, the invalid pension would be replaced by a service gratuity under Rule 44(2), but the retirement gratuity would still be paid.

Invalid pension under the National Pension System and the Unified Pension Scheme

An employee who joined central government service on or after 1 January 2004 is covered by the National Pension System rather than the old defined-benefit scheme, and the invalid-pension question is handled through an option. Under Rule 10 of the CCS (Implementation of National Pension System) Rules 2021, every NPS-covered employee elects at joining, through the prescribed option form, whether on discharge on invalidation or disablement they take the benefits under the NPS or the benefits under the old CCS (Pension) and CCS (Extraordinary Pension) framework, that is invalid pension, disability pension, family pension, and the constant attendant allowance. If the old-scheme benefits are chosen, the government’s contribution and its returns in the corpus are transferred to the government while the employee’s own contribution and its returns are refunded to the employee, with interest at Public Provident Fund rates, per the Department of Pension and Pensioners’ Welfare Office Memorandum dated 14 October 2024. This spares an NPS employee invalidated early, whose corpus is naturally small, from being left with only a thin annuity from a few years of contributions.

The Unified Pension Scheme, operative from 1 April 2025, is the assured-payout option layered over the NPS architecture. Its treatment of a discharge on invalidation for the employees who opt into it should be read from the current DoPPW notifications rather than assumed, since the assured-payout mechanics were still being detailed through 2025 and 2026; an employee weighing the schemes should confirm the medical-exit position with their office, and the NPS vs OPS vs UPS comparison sets out the wider choice.

Invalid pension against disability pension

The two are routinely confused, so the distinction is worth stating plainly. Invalid pension is the ordinary pension for permanent incapacity, whatever the cause. Disability pension is the enhanced benefit for a disablement attributable to or aggravated by service, which adds a disability element on top of the pension under the CCS (Extraordinary Pension) Rules 2023. A case with no causal link to service, called Category A in those rules, falls back to the ordinary invalid pension, not the enhanced disability pension. The full mechanics of the disability element, the four categories, the broad-banding, and the constant attendant allowance are in the disability and invalid pension article; the point here is only that invalid pension is the baseline, and disability pension is the uplift where the harm came from the service.

The tax position

The tax treatment is the point civil employees most often get wrong, because the well-known exemption is a defence exemption. For armed forces personnel invalided out on a disability attributable to service, both the service and disability elements of the pension are exempt from income tax under long-standing CBDT instructions. That exemption rests on administrative circulars framed for military service, not on an express section of the Income-tax Act, and there is no equivalent statutory or CBDT exemption extending it to civil employees.

For a central government civil employee, therefore, an invalid pension is generally taxable as pension, taxed under the head salaries in the ordinary way, subject to the standard deduction and any generally available relief, as the income tax for pensioners article sets out. The commuted lump sum a civil employee takes on invalidation is itself exempt under Section 10(10A), as it is for any government pensioner, but the monthly invalid pension is not exempt merely because it followed a medical retirement.

Where the civil pensioner is a person with a disability, the relief comes not as an exemption of the pension but as a deduction from taxable income: Section 80U for the pensioner’s own disability, and Section 80DD where they maintain a dependant with a disability, each a fixed deduction that reduces the tax without making the invalid pension itself tax-free. A civil employee should not assume the armed-forces treatment applies to them, and anyone with a specific claim should verify the position with their Drawing and Disbursing Officer, the Pay and Accounts Office, and a tax adviser.

Frequently Asked Questions (FAQs)

What is invalid pension?

Invalid pension is the pension granted to a central government civil employee who is retired because a medical board certifies a permanent bodily or mental infirmity that makes them unfit for further service, or for the particular post they hold. It is an ordinary pension under Rule 39 of the CCS (Pension) Rules 2021, computed at 50% of emoluments, and the cause of the incapacity does not matter.

Do I need 10 years of service to get an invalid pension?

No. The usual 10-year minimum qualifying service for a pension is expressly waived for invalid pension. An employee invalidated before completing 10 years, who satisfies the conditions in Rule 39(9), still gets the invalid pension at 50% of emoluments. If those conditions are not met, a service gratuity is paid instead under Rule 44(2).

How much is invalid pension?

It is computed exactly like a superannuation pension: 50% of the last basic pay, or of the average emoluments of the last 10 months, whichever is more beneficial, subject to a minimum of Rs. 9,000 a month and a maximum of Rs. 1,25,000 a month, with dearness relief on top. Since 1 January 2006 there is no proportionate reduction for shorter service above the qualifying threshold.

What is the difference between invalid pension and disability pension?

Invalid pension is the ordinary pension paid when a medical board certifies permanent incapacity, whatever the cause. Disability pension is the enhanced benefit under the CCS (Extraordinary Pension) Rules 2023 paid when the disablement is attributable to or aggravated by service; it adds a disability element on top of the pension. A case with no service link gets invalid pension, not disability pension.

Can I commute part of an invalid pension?

Yes. An invalid pensioner can commute up to 40% of the pension for a lump sum, on the same terms as any other pensioner, under the CCS (Commutation of Pension) Rules 1981, subject to medical clearance where required. Dearness relief continues on the full un-commuted pension, and the commuted portion is restored after 15 years.

Is invalid pension taxable?

Generally yes. A civil employee’s invalid pension is taxed as pension under the head salaries in the ordinary way, subject to the standard deduction. The well-known income-tax exemption for a disability pension rests on CBDT instructions framed for the armed forces and does not, on the current material, extend to civil central government employees. Anyone with a specific claim should verify with their DDO and a tax adviser.

Can an employee be refused invalidation and kept in service?

Yes. If the medical board finds the employee fit for some less laborious service rather than wholly incapacitated, invalidation can be declined, and the employee may be retained or re-employed on a lower post that they are able to perform, instead of being pensioned off. Invalidation is for permanent incapacity for the service, not merely for the current post where a suitable alternative exists.

Does invalid pension apply to NPS employees?

An employee who joined on or after 1 January 2004 and is covered by the National Pension System can receive invalid pension and family pension benefits where the option under the CCS (Implementation of NPS) Rules 2021 was exercised, in place of the accumulated pension corpus. For the Unified Pension Scheme, operative from 1 April 2025, the treatment of a medical exit should be confirmed from the current DoPPW notifications rather than assumed.
