Quick summary

Section 80DDB allows a deduction for the amount actually paid on treatment of specified serious diseases, up to ₹40,000, or up to ₹1,00,000 if the patient is a senior citizen.
The deduction is reduced by any amount received from insurance or reimbursed by an employer, so only your net out-of-pocket cost counts.
It covers you and your dependants (spouse, children, parents, brothers and sisters), and needs a prescription from the specialist named in the rules.
From Tax Year 2026-27 it is section 128 of the Income-tax Act, 2025, and it is available only in the old tax regime.

Treating a serious illness is expensive. Section 80DDB lets a resident individual or HUF deduct what they actually pay on the treatment of certain specified diseases, up to a limit. It reduces taxable income, and is available only under the old tax regime.

From Tax Year 2026-27 the provision is section 128 of the Income-tax Act, 2025. For FY 2025-26 (assessment year 2026-27) it is section 80DDB of the 1961 Act.

Who can claim?

A resident individual, for treatment of self or a dependant.
A HUF, for treatment of any of its members.
A dependant means the spouse, children, parents, brothers and sisters of the individual. Companies and other entities cannot claim.

Deduction limit

Patient	Maximum deduction
Under 60 years	₹40,000
Senior citizen (60 or more at any time during the year)	₹1,00,000

The deduction is the amount actually paid or the limit, whichever is less. It is then reduced by any amount received under an insurance policy or reimbursed by an employer for that treatment.

Examples

You pay ₹80,000 for treatment and get ₹30,000 from the insurer. For a patient under 60, the limit is ₹40,000 (less than the ₹80,000 paid), so the deduction is ₹40,000 less ₹30,000, which is ₹10,000. For a senior citizen the amount paid (₹80,000) is less than the limit of ₹1,00,000, so the deduction is ₹80,000 less ₹30,000, which is ₹50,000.
You pay ₹80,000 and the insurer pays ₹60,000. For a patient under 60 it is ₹40,000 less ₹60,000, so there is no deduction. For a senior citizen it is ₹80,000 less ₹60,000, which is ₹20,000.

In short, take the lower of the amount paid and the limit, then subtract what the insurer or employer paid.
