Section 80DDB: Tax Deduction for Medical Treatment of Specified Diseases
Eligibility, qualifying illnesses under Rule 11DD, the deduction for senior citizens, medical evidence and the effect of insurance or employer reimbursement.
What is Section 80DDB?
Section 80DDB of the Income-tax Act, 1961 provided a deduction to a resident individual or resident Hindu undivided family (HUF) for actual expenditure on medical treatment of specified diseases or ailments. The qualifying illnesses are prescribed under Rule 11DD of the Income-tax Rules, 1962. A disease is not eligible merely because its treatment is expensive.
For an individual, the treatment may be for the taxpayer or a qualifying dependant: spouse, children, parents, brothers or sisters who are wholly or mainly dependent for support and maintenance. For an HUF, treatment must relate to an eligible member of the HUF. A senior citizen for this section means a resident individual aged 60 years or more at any time during the relevant previous year.
Important legislative context: The Income-tax Act, 2025 took effect from 1 April 2026. The section number and deduction rules explained here describe the 1961 Act for assessment years to which it applies, including historical or transitional matters. For tax years under the 2025 Act, consult the corresponding enacted provision and applicable rules rather than automatically using the old section number.
Section 80DDB deduction limits under the 1961 Act
| Patient category | Maximum deduction | Actual deduction |
|---|---|---|
| Qualifying patient below age 60 | Rs. 40,000 | Lower of eligible treatment expenditure or Rs. 40,000, less qualifying reimbursement |
| Qualifying resident senior citizen (age 60 or above) | Rs. 1,00,000 | Lower of eligible treatment expenditure or Rs. 1,00,000, less qualifying reimbursement |
The deduction is limited to amounts actually paid during the relevant previous year. Under the proviso to Section 80DDB, amounts received from an insurer or reimbursed by an employer for that treatment reduce the allowable deduction. The statutory wording and its application should be checked for the particular assessment year.
Section 80DDB is separate from Section 80D (health insurance and specified medical expenditure) and Section 80DD (maintenance of a dependant with disability). The same expenditure should not be claimed twice.
Which diseases qualify under Rule 11DD?
Rule 11DD identifies specified categories of diseases or ailments. These include the following, subject to the exact statutory descriptions and medical criteria in force for the relevant year:
- Neurological diseases where the disability level is certified as 40% or more, including dementia, dystonia musculorum deformans, motor neuron disease, ataxia, chorea, hemiballismus, aphasia and Parkinson's disease.
- Malignant cancers.
- Full-blown acquired immunodeficiency syndrome (AIDS).
- Chronic renal failure.
- Haematological disorders including haemophilia and thalassaemia.
This is an explanatory summary, not a substitute for the current wording of Rule 11DD and any amendments or applicable specialist requirements. Verify the medical diagnosis against the rule before claiming.
Medical prescription, specialist and supporting documents
Under the later wording of Section 80DDB and Rule 11DD, a qualifying prescription from the prescribed specialist is necessary. Depending on the illness, this may involve a neurologist, oncologist, urologist, haematologist, immunologist or another specialist prescribed by the rules. Rule 11DD sets out the required particulars of the prescription and relevant qualifications; special arrangements can apply to prescriptions issued in government hospitals.
Keep the specialist's prescription, diagnosis records, medical bills, payment receipts, proof of relationship and dependency where applicable, and details of any insurance or employer reimbursement. Under the electronic return process, supporting documents are generally retained for verification rather than physically attached to the return; comply with the applicable filing instructions.
Old versus concessional tax regime
For years governed by the Income-tax Act, 1961, Section 80DDB was generally a Chapter VI-A deduction available under the old tax regime when its conditions were met. It was generally not available under Section 115BAC's concessional regime. The applicable election, assessment year and statutory exceptions must be checked. The Income-tax Act, 2025 has its own corresponding framework for tax years beginning from 1 April 2026.
Illustrative calculations
Example 1: A resident taxpayer spends Rs. 65,000 on qualifying treatment for a dependent parent aged 55 and receives no reimbursement. Under the 1961 Act's applicable provisions, the deduction is limited to Rs. 40,000.
Example 2: A resident taxpayer spends Rs. 1,30,000 on qualifying treatment for a resident parent aged 67 and receives Rs. 25,000 from an insurer. The otherwise eligible ceiling is Rs. 1,00,000; after accounting for reimbursement under the statutory proviso, the deductible amount is Rs. 75,000, assuming all other conditions are satisfied.
Example 3: A qualifying resident senior citizen incurs Rs. 72,000 of eligible medical expenditure without reimbursement. The deduction can be Rs. 72,000, not an automatic Rs. 1,00,000.
