Summary
The no claim bonus does not apply to a standalone third-party car insurance policy in India. NCB is a discount that is reserved exclusively for the Own Damage (OD) premium. But the third-party-only policy has no OD component to discount. You start building NCB or no claim bonus only once you hold a comprehensive policy or a standalone OD cover alongside your mandatory third-party car insurance. The discount ranges from 20% to 50% and is tied to you as the policyholder. So when you renew or change a policy, it automatically applies.
Introduction
Every year, millions of car owners in India renew a basic third-party policy simply because the law requires it, and many quietly assume their claim-free record is building up a discount. But the scenario is different. If you have ever typed what is NCB in car insurance into a search bar and wondered whether it applies to your third-party-only cover, the honest answer might surprise you.
This article breaks down exactly why no claim bonus does not apply to third-party car insurance, how NCB actually works, and what you need to change to start earning it.
What Is No Claim Bonus or NCB in Car Insurance?
No claim bonus, commonly known as anNCB, is a discount insurers give you for every consecutive year you complete without filing an own-damage claim. It exists to reward the careful drivers and to keep low-risk customers from subsidising accident-prone ones.
As per IRDAI's standardised motor tariff norms, NCB starts at 20% after your first claim-free year and rises step by step to a maximum of 50% at the five-year mark. Every general insurer in India must follow the same slab structure; no company is permitted to offer a higher or lower rate.
What Is the NCB Slab Structure Set by IRDAI?
● 1 year claim-free: 20% NCB discount on OD premium
● 2 years claim-free: 25%
● 3 years claim-free: 35%
● 4 years claim-free: 45%
● 5 years or more claim-free: 50% (maximum)
Note: This discount is calculated only on the Own Damage premium of your policy, and never on the total premium you pay.
What Is Third Party Car Insurance?
Third-party car insurance is the minimum cover mandated under the Motor Vehicles Act, 1988. It pays for legal liability arising from injury, death, or property damage you cause to another person or their vehicle. It does not pay a single rupee towards damage to your own car, whatever the cause behind that.
Because this cover has only one component, liability, there is no own damage premium anywhere in the policy where theNo Claim Bonus discount applies. While checking for a car insurance online, you can check the details of what is included within a policy.

Does No Claim Bonus Apply to Third Party Car Insurance in India?
No. No claim bonus does not accrue on a standalone third-party-only policy, and it never reduces a third-party premium even if you also hold a separate OD policy. Two separate rules explain this clearly:
● NCB is legally and structurally linked to the Own Damage section of a motor policy. A third-party-only policy has no Own Damage Policy section.
● Third-party premiums are fixed annually by IRDAI purely on the basis of engine capacity (cc) and vehicle category. Your driving or claims record has no bearing on this figure, so there is nothing for a bonus to discount.
Moreover, staying claim-free for five years on a third-party-only policy earns you nothing extra at renewal. The premium you pay in year six is the same IRDAI-notified rate as everyone else driving the same class of vehicle.
Why Doesn't NCB in Insurance Apply to a Third-Party-Only Policy?
The logic behind NCB in insurance is that it rewards policyholders who do not make claims for damage to their own vehicle.
The Own Damage (OD) section of your car insurance policy covers repair or replacement of your vehicle, and insurers will give a discount to drivers who are at a lower claims risk. Third-party liability premiums are different. These premiums are regulated by IRDAI and are meant to compensate third parties for injury, death or property damage arising from the use of insured vehicles.
Because the premium is determined by regulatory guidelines rather than an individual driver's claims history, a no-claim bonus cannot be applied to this portion of the policy.
1. Interesting Fact
Third-party premiums for private cars are reviewed and re-notified by IRDAI every financial year and are uniform across every city and state in India. A car owner in Mumbai and one in a small town in Bihar pay the exact same third-party premium for an identical engine capacity, no claim bonus or driving record notwithstanding.
How Is NCB Calculated on a Comprehensive Car Insurance Policy?
NCB is applied only to the OD premium, before add-on costs like zero depreciation or engine protection are added back in. Here's a simple example:
Suppose your OD premium is ₹15,000 and your third-party premium is ₹3,400. After three consecutive claim-free years, your NCB slab is 35%. Your OD premium drops to ₹9,750, while your third-party premium of ₹3,400 stays exactly the same, since it is fixed by IRDAI and unrelated to your no-claim bonus. Reviewing yourcomprehensive car insurance policy each year helps you track this properly.
1. Pro Tip
A small claim can cost more than it saves. Filing a claim for minor damage resets your NCB to zero, and rebuilding it from 20% back to 50% takes another five claim-free years. Before filing a low-value claim, compare the repair cost against the NCB discount you stand to lose over the next renewal cycles; it is often cheaper to pay out of pocket and keep your slab intact.
How Do You Protect or Transfer Your No Claim Bonus?
● Keep your policy active. Renew before expiry, or at least within 90 days of it, since a lapse beyond this window wipes your NCB to zero.
● Avoid filing claims for minor, low-value damage that costs less to repair out of pocket than the NCB you would lose.
● Request your NCB certificate from your current insurer when switching providers, selling your car, or buying a new one; it is valid for three years.
● Remember that the NCB belongs to you. Therefore, it moves with you to a new car or a new insurer, but never to the person who buys your old car.
● Consider an NCB protection add-on if you hold a high slab (35% and above), so that one or two claims in a year don't reset your discount to zero.
● Buy or renew your car insurance online through your insurer's portal or app, where your existing NCB is usually auto-verified and applied at checkout.

FAQs
No. A no claim bonus applies only to the Own Damage component of a policy. A third-party-only policy has no OD component, so no NCB accrues, regardless of how many years you stay claim-free.
No. Even under a comprehensive policy, NCB is calculated only on the OD premium. The third-party portion is fixed by IRDAI based on engine capacity and stays the same irrespective of your NCB slab.
If your policy lapses for more than 90 days, your accumulated NCB is permanently lost and you restart from 0% on your next comprehensive or OD policy.
