No-Claim Bonus (NCB) — Health Insurance Reward for Claim-Free Years

Definition

In the context of Indian health insurance, No-Claim Bonus (NCB) — also called Cumulative Bonus in some product wordings — is a benefit that rewards policyholders who do not file any claim during a policy year by automatically increasing their sum insured at next renewal without a corresponding premium increase. IRDAI requires health insurers to disclose NCB structure in policy terms under the IRDAI (Health Insurance) Regulations 2016. Note: in motor insurance, NCB operates as a discount on own-damage premium — that is a separate mechanism and is not covered in this entry.

How the product works

For every complete claim-free policy year, the insurer adds an NCB increment to the base sum insured. Typical structures:

• Simple NCB: 10%-50% of base sum insured added per claim-free year, up to a cumulative cap (often 50%-100% of original sum insured). Example: Rs.5 lakh base, 20%/year NCB, 100% cap — maximum reaches Rs.10 lakh after 5 claim-free years.
• Accelerated NCB: some newer products add 25-50% per year with higher caps, reaching significant cover multiples faster.
• NCB protection rider: an optional add-on (at extra premium) that prevents NCB from reducing even if one claim is made in a year.

NCB reduction on claim: when a claim is made, NCB typically resets partially or fully depending on product terms — common structures reset to zero or reduce by one increment per claim year.

NCB portability: under IRDAI health insurance portability rules (operative since 2011, reinforced in 2016 Regulations), accrued NCB must be honoured by the new insurer when a policyholder ports their health policy. The new insurer applies its own NCB structure going forward.

Family floater NCB: NCB applies to the shared sum insured pool. A single claim by any family member typically nullifies the NCB increment for that policy year across the entire floater.

Tax treatment

NCB is a non-cash benefit — the increase in sum insured does not constitute taxable income. It improves coverage efficiency without changing the Section 80D deduction calculation. The premium paid (including for NCB protection riders) continues to qualify for Section 80D deduction within applicable limits (Rs.25,000/Rs.50,000 for senior citizens). No specific Income Tax Act provision directly governs NCB; it is a product feature without standalone tax consequence.

What to look at (factual framework)

• NCB cap: the absolute ceiling matters most. A 50% cap means a Rs.5 lakh policy can only grow to Rs.7.5 lakh via NCB regardless of claim-free years. Compare caps explicitly across products.
• NCB reset terms: verify whether one claim year wipes all accumulated NCB or only the most recent increment. "Cumulative bonus" products may have more graduated reset terms.
• NCB vs. adequate base sum insured: NCB is not a substitute for starting with adequate base coverage. Relying on NCB to reach adequate cover over time means being underinsured in early years — a meaningful risk.
• Super top-up interaction: NCB growth on a base policy reduces the effective deductible gap a super top-up needs to cover — understanding the interaction helps in overall coverage planning.
• NCB portability confirmation: request written confirmation of accrued NCB from the existing insurer before porting; confirm the new insurer accepts the transferred amount before completing renewal.

Worked example

Anika holds a Rs.5 lakh individual health policy with 20% per-year NCB (cumulative cap: 100%). Policy year timeline:

• Year 1 claim-free: sum insured at next renewal is Rs.6 lakh
• Year 2 claim-free: sum insured is Rs.7 lakh
• Year 3 — claim of Rs.1.2 lakh filed: NCB resets, sum insured reverts to Rs.5 lakh at next renewal
• Year 4 claim-free: sum insured is Rs.6 lakh again

Premium remains Rs.12,000/year throughout (absent insurer-initiated general rate revision). The NCB delivered Rs.2 lakh of additional coverage in Year 2 at zero marginal cost — the compounding benefit of claim-free years is most valuable over a 5-10 year horizon with no major claims.
