Key Takeaways
- Section 80DDB lets you deduct medical expenses for treating a specified disease for yourself or a dependent. Available only under the old tax regime.
- Deduction limit: Rs 40,000 if the patient is below 60 years; Rs 1,00,000 if the patient is 60 or above (senior citizen).
- The limit is determined by the patient's age, not the taxpayer's age.
- Qualifying diseases are listed under Rule 11DD of the Income Tax Rules: cancers, neurological diseases, AIDS, chronic renal failure, haemophilia, and thalassaemia.
- You need a specialist certificate (oncologist for cancer, neurologist for neurological conditions, etc.) from a government hospital. Form 10-I is no longer required.
- Reimbursement adjustment: if you receive any insurance or employer reimbursement, the deduction is reduced by that amount.
When a family member is diagnosed with cancer, dementia, or chronic renal failure, the treatment costs in India can run into several lakhs per year. Section 80DDB of the Income Tax Act 1961 provides a specific deduction for these medical expenses, separate from the general health insurance deduction under Section 80D. Millions of Indian families incur these expenses every year, yet a large number either miss the deduction entirely or claim it incorrectly.
This guide covers every aspect of Section 80DDB: who qualifies, which diseases are covered, how the deduction limit works, what certificate you need, and how to claim it correctly in your ITR.

Who Can Claim Section 80DDB
Section 80DDB is available to:
- Resident individuals who incur medical expenses for themselves or a dependent (spouse, children, parents, or siblings)
- Hindu Undivided Families (HUFs) for medical expenses incurred for any member of the HUF
Non-resident Indians (NRIs) cannot claim Section 80DDB.
Dependent for this purpose means a person who depends primarily on the taxpayer for their normal needs. The dependent need not be financially entirely dependent; it is a question of who bears the medical expenses.
Tax regime restriction: Section 80DDB is available only under the old tax regime. The new tax regime under Section 115BAC does not allow this deduction. If you are on the default new regime, you must opt out to the old regime to claim 80DDB. See our old vs new tax regime guide for when the switch makes financial sense.
Specified Diseases Under Rule 11DD
Only expenses for diseases listed under Rule 11DD of the Income Tax Rules qualify. The full list is as follows:
| Category | Disease |
|---|---|
| Neurological diseases (with disability of 40% or more) | Dementia, Dystonia Musculorum Deformans, Motor Neuron Disease, Ataxia, Chorea, Hemiballismus, Aphasia, Parkinson's Disease |
| Cancer | Malignant cancers (all types: carcinoma, sarcoma, lymphoma, leukaemia, etc.) |
| Immunodeficiency | Full Blown Acquired Immuno-Deficiency Syndrome (AIDS) |
| Renal | Chronic Renal Failure |
| Haematological | Haemophilia, Thalassaemia |
Plain-English summary of each category:
- Neurological diseases: Brain and nervous system conditions causing significant disability. Parkinson's and dementia are the most commonly claimed. Critically, the neurological disease must cause a disability of 40% or more in the patient to qualify under Rule 11DD.
- Malignant cancers: Any cancer diagnosis qualifies. This is the single most frequently claimed category under 80DDB.
- AIDS: Only full-blown AIDS qualifies, not merely an HIV-positive diagnosis.
- Chronic Renal Failure: Also called end-stage renal disease, typically requiring dialysis or kidney transplant.
- Haemophilia and Thalassaemia: Both are blood disorders requiring ongoing treatment (factor infusions and blood transfusions respectively).
If the disease is not in this list, Section 80DDB does not apply. Expenses for diabetes, hypertension, heart disease, tuberculosis, or arthritis are not covered under 80DDB (though some may qualify under other sections or as general medical expenses).
Deduction Limits: Patient's Age Controls the Cap
The deduction cap depends entirely on the age of the patient, not the age of the taxpayer paying the bills.
| Patient's age | Maximum deduction |
|---|---|
| Below 60 years | Rs 40,000 |
| 60 years or above (senior citizen) | Rs 1,00,000 |
Example illustrating the age rule:
Priya (age 35) pays Rs 90,000 for her father's (age 72) cancer treatment. The deduction cap is Rs 1,00,000 because her father (the patient) is a senior citizen, regardless of Priya's age. She can claim the full Rs 90,000.
Conversely, if Ravi (age 62) pays Rs 90,000 for treatment of his daughter (age 28, diagnosed with chronic renal failure), the deduction cap is Rs 40,000 because the patient (the daughter) is below 60, despite Ravi being a senior citizen himself.
This is a frequently missed point. Always look at the patient's date of birth, not your own.
The deduction is limited to actual expenses: You cannot claim more than the amount actually spent. If you spent Rs 30,000 and the cap is Rs 40,000, the deduction is Rs 30,000.
Reimbursement Adjustment: The Net Amount Rule
If you received any reimbursement for the medical expenses from either:
- A health insurance policy, or
- Your employer's medical reimbursement scheme
the deduction is reduced by the amount reimbursed.
Formula:
Section 80DDB deduction = Actual medical expenses incurred (capped at Rs 40,000 or Rs 1,00,000) minus insurance/employer reimbursement received
Example: Arjun spends Rs 80,000 on his mother's (age 65) cancer treatment. His health insurance policy reimburses Rs 30,000. His 80DDB deduction is Rs 80,000 minus Rs 30,000 = Rs 50,000 (within the Rs 1,00,000 cap for senior citizen patient).
Keep copies of insurance claim settlement letters and employer reimbursement statements as supporting documentation.
Specialist Certificate: What You Need
A specialist certificate is mandatory for claiming Section 80DDB. Form 10-I is no longer required following the Finance Act 2015 amendment. You now need a certificate issued by a specialist in the relevant field from a government hospital.
| Disease category | Required specialist |
|---|---|
| Neurological diseases | Neurologist (DM Neurology or equivalent) |
| Cancer | Oncologist or specialist in oncology |
| AIDS | Specialist in internal medicine or infectious diseases |
| Chronic Renal Failure | Nephrologist or urologist |
| Haemophilia, Thalassaemia | Haematologist |
What the certificate must contain:
- Name and age of the patient
- Name of the disease with confirmation it falls under Rule 11DD
- Date of diagnosis and period of treatment
- Name, designation, registration number, and signature of the specialist
- Name and address of the government hospital
The certificate does not need to be filed with your ITR. Keep it with your records and produce it if the tax officer asks for verification.
Government hospital requirement: The specialist must be from a government hospital (central government, state government, or local body hospital). Certificates from private hospital specialists, even well-known oncologists or neurologists, do not satisfy the requirement under Rule 11DD.
How to Claim Section 80DDB in Your ITR
- Opt for the old tax regime. Salaried filers can choose at ITR filing time. Business income filers must file Form 10-IEA before the due date.
- Gather documentation: Medical bills, payment receipts (preferably non-cash), insurance settlement letters if applicable, and the specialist certificate.
- Open Chapter VI-A in your ITR form (ITR-1, ITR-2, or ITR-3 depending on your income type).
- Enter the net deduction (expenses minus reimbursements) under the Section 80DDB row.
- Mention the disease and relationship to the patient in the fields provided. For ITR-1 filers, the Schedule VI-A under Part C has a specific 80DDB line.
The deduction reduces your gross total income before tax is applied. At the 30% slab plus 4% cess, a Rs 1,00,000 deduction saves Rs 31,200 in tax.
Common Mistakes to Avoid
1. Claiming for a disease not in Rule 11DD. Heart disease, diabetes, stroke, and orthopedic conditions are not covered. Verify the exact diagnosis against the Rule 11DD list before filing.
2. Using the taxpayer's age instead of the patient's age. The Rs 1,00,000 limit applies when the patient is a senior citizen, regardless of the taxpayer's age.
3. Not adjusting for reimbursements. Claiming the full expense without deducting insurance or employer reimbursements is incorrect and may lead to a notice under Section 143(1).
4. Certificate from a private hospital specialist. Only government hospital specialists qualify. Confirm the hospital's status before obtaining the certificate.
5. Missing the neurological disease disability threshold. Neurological conditions require a disability of 40% or more to qualify. A diagnosis alone is not enough; the specialist certificate must confirm the disability percentage.
6. Claiming in the new tax regime. Section 80DDB is not available under the new tax regime. If you filed under the new regime, the deduction will be disallowed.

Is Form 10-I still required for Section 80DDB?
No. Form 10-I was abolished by the Finance Act 2015. You now need a certificate on plain paper from a specialist in the relevant field working at a government hospital. Keep the certificate with your records; you do not need to file it with your ITR.
My father has dementia. Does Section 80DDB apply?
Dementia is listed under Rule 11DD as a neurological disease. It qualifies, provided a neurologist from a government hospital certifies that the condition results in a disability of 40% or more. If your father is 60 or above, the deduction limit is Rs 1,00,000.
I received health insurance reimbursement. How does it affect my 80DDB deduction?
The deduction is the actual expense minus any insurance or employer reimbursement received. For example, if you spent Rs 70,000 and received Rs 20,000 from insurance, the deduction is Rs 50,000 (subject to the age-based cap).
Can an HUF claim Section 80DDB?

Is Section 80DDB separate from Section 80D?
