Health insurance is one of the rare areas in personal finance where the sensible thing to do and the tax-efficient thing to do line up almost perfectly — buying cover protects you financially in a medical emergency, and the premium you pay can also reduce your taxable income under section 80D, under the old regime.
Here's roughly how the deduction works. Premiums paid for yourself, your spouse, and your children can qualify for a deduction up to a certain limit, with an additional, separate limit available for premiums paid toward your parents' health cover — meaning a household covering both their own family and ageing parents can potentially claim two separate deduction buckets, not just one combined limit.
Why this combination matters: many people buy health insurance purely for the protection, without realising there's also a meaningful tax benefit layered on top — or they buy insurance and separately try to find other 80C-eligible investments to fill their deduction room, not realising 80D operates as a distinct, additional limit rather than competing with 80C for the same space.
The practical habit: if you're paying health insurance premiums for yourself or your parents, make sure you're actually claiming the 80D deduction when filing under the old regime — it's easy to forget if your employer's payroll team didn't proactively ask about it. And if you don't yet have a policy for your parents, the dual benefit of protection plus a separate deduction is worth weighing alongside the straightforward case for the cover itself.
