What is a voluntary top-up health plan for employees?

A voluntary top-up health plan is an optional additional layer of health insurance that employees can buy on top of their employer-paid group health cover. The employee pays the premium (usually through payroll deduction), and the top-up sum insured kicks in once the base sum insured is exhausted. Voluntary top-ups let employees increase their protection without waiting for the employer to raise the base cover.

What is a voluntary top-up plan?

A voluntary top-up plan is a group insurance product offered by the same insurer that underwrites the employer's base policy, sold at group rates but paid for by the employee. It works on a deductible basis: the top-up sum insured is available once claims in a policy year cross the employer's base sum insured (which acts as the deductible). Voluntary top-ups are also called super top-up when the deductible applies across all claims in a year rather than per claim.

How does a voluntary top-up plan work in practice?

If the employer's base group policy has a family floater sum insured of Rs 5 lakh, and the employee has bought a voluntary top-up of Rs 10 lakh, the total cover available is Rs 15 lakh. For a hospitalisation claim of Rs 12 lakh, the base policy pays the first Rs 5 lakh, and the top-up covers the remaining Rs 7 lakh. The employee does not pay out of pocket, and both settlements typically happen through the same TPA and cashless workflow.

Why do employers offer voluntary top-ups?

Voluntary top-ups let employers extend meaningful additional cover without increasing their own premium spend. Group-rated top-up premiums are meaningfully lower than what employees would pay for equivalent individual retail cover, since the risk pool is larger and underwriting is simpler. Offering the top-up option also reduces the pressure on the employer to raise the base sum insured every year to keep up with medical inflation.

Do employees need medical tests for a voluntary top-up?

Usually no. Voluntary top-ups underwritten as extensions of the employer's group policy typically waive fresh medical tests and honour the base policy's pre-existing disease treatment. This is a distinguishing feature: an employee cannot access this underwriting shortcut on a retail top-up policy purchased individually.

Is voluntary top-up premium tax-deductible?

Yes, under the old tax regime. Premium paid by the employee on a voluntary top-up plan is generally eligible for deduction under Section 126 of the Income Tax Act, 2025 (the renumbered Section 80D of the 1961 Act), within the applicable limits: Rs 25,000 for self and family, Rs 50,000 for senior citizen parents, and Rs 1 lakh maximum. The deduction is not available under the new tax regime.

What happens to the voluntary top-up when the employee leaves?

Voluntary top-up cover typically ends on the employee's last working day, similar to the base group cover. Some insurers offer a portability option to convert the top-up into an individual retail policy, subject to the insurer's terms and fresh premium at retail rates. This is worth checking at the point of enrolment.

How Plum approaches this

Plum works with employers to structure voluntary top-up options that give employees the choice to layer additional cover at group rates, rather than being limited to whatever the employer's base sum insured happens to be. Across Plum's group book, claims NPS runs at 79 and cashless pre-authorisation clears in a median of 45 minutes, with the same operational discipline applied to top-up claims once the base sum insured is exhausted. Plum places group cover from a minimum of 7 employees, working with partner insurers including ICICI Lombard, HDFC ERGO, Bajaj Allianz, Star Health, Niva Bupa, and Aditya Birla Health Insurance, each of which offers a different voluntary top-up structure.

Frequently asked questions

Is voluntary top-up available at all group policies?

Most modern group policies offer a voluntary top-up option, though the sum insured tiers and pricing vary by insurer.

Can the voluntary top-up cover different family members from the base policy?

Typically no. The top-up follows the family definition of the base policy: employee, spouse, children, and parents where included.

Is voluntary top-up cheaper than an individual top-up?

Yes, meaningfully. Group-rated voluntary top-ups are usually 30% to 50% cheaper than equivalent individual retail top-ups.

Does the voluntary top-up have its own waiting periods?

Waiting periods are usually inherited from the base group policy, meaning existing employees do not face fresh waiting periods on the top-up.

Can an employee opt in or out of the top-up mid-year?

Most employers offer enrolment windows once a year at policy renewal, with limited mid-year enrolment for life events such as marriage or a new child.

How is the top-up premium collected?

Premium is usually collected through monthly payroll deduction, spread over the policy year.
