Section 80DDB: Deduction for Specified Illness Treatment

Short answer: Section 80DDB of the Income-tax Act allows a resident individual or HUF to claim a deduction for medical expenses incurred on the treatment of specified diseases for themselves or a dependant. The deduction limit is ₹40,000 (or ₹1,00,000 if the patient is a senior citizen). This benefit is only available if you opt for the old tax regime and requires a prescription from a specialist doctor.

Who can claim the Section 80DDB deduction?

Only a resident Individual or a Hindu Undivided Family (HUF) can claim this deduction. The claim must be for medical treatment expenses incurred for the taxpayer themselves or a dependant. For an individual, 'dependant' includes their spouse, children, parents, and siblings who are wholly or mainly dependent on the taxpayer for support and maintenance. For a HUF, the deduction can be claimed for any member of the family.

What are the deduction limits under Section 80DDB?

The maximum deduction available depends on the age of the person undergoing treatment.

• For patients below 60 years of age: The deduction is capped at the actual amount spent or ₹40,000, whichever is lower.
• For patients who are senior citizens (60 years or more): The deduction is capped at the actual amount spent or ₹1,00,000, whichever is lower.

It is crucial to note that the deduction amount is reduced by any sum received from an insurance policy or reimbursed by an employer for the medical treatment.

Which diseases are covered under Section 80DDB?

The deduction is available only for diseases specified in Rule 11DD of the Income-tax Rules, 1962.

Neurological Diseases (where disability level is certified as 40% or more):

• Dementia
• Dystonia Musculorum Deformans
• Motor Neuron Disease
• Ataxia
• Chorea
• Hemiballismus
• Aphasia
• Parkinson's Disease

Other Specified Diseases:

• Malignant Cancers
• Full Blown Acquired Immuno-Deficiency Syndrome (AIDS)
• Chronic Renal failure
• Haematological disorders like Haemophilia or Thalassaemia

Can I claim 80DDB under the new tax regime?

No, you cannot claim a deduction under Section 80DDB if you choose the new tax regime (under Section 115BAC). The new tax regime, which is the default option from FY 2023-24 (AY 2024-25) onwards, offers lower tax rates but disallows most deductions available under Chapter VI-A, including Section 80DDB. To claim this benefit, you must explicitly opt for the old tax regime when filing your income tax return. You can learn more about this choice in our new vs. old tax regime guide.

What documents are required to claim this deduction?

While you don't need to attach documents to your ITR, you must obtain and keep them in your records for future reference in case of an income tax notice or scrutiny.

1. Prescription (Form 10-I): A prescription from a qualified medical specialist is mandatory. The specialist must be a neurologist, oncologist, urologist, haematologist, immunologist, or a doctor with a Doctorate of Medicine (MD) in general medicine, as relevant to the disease.
2. Proof of Expenditure: Keep all bills, receipts, and vouchers related to the medical treatment, including doctor's consultation fees, hospitalisation charges, medicine bills, and diagnostic test reports.
3. Proof of Reimbursement: If you received any payment from an insurer or your employer, keep documentary evidence of the same.

How does insurance reimbursement affect the 80DDB deduction?

The amount of deduction you can claim under Section 80DDB is reduced by any amount you receive from an insurance company or as a reimbursement from your employer. For example, if you spent ₹90,000 on treatment for a senior citizen parent and your insurance company paid ₹30,000, your net expenditure is ₹60,000. You can claim ₹60,000 as a deduction, as it is less than the ₹1,00,000 limit.

Worked example

Ms. Priya, a 45-year-old software engineer in Bengaluru, has a total income of ₹20,00,000 for the financial year 2025-26. Her father, aged 68 and dependent on her, is undergoing treatment for Parkinson's Disease.

• Tax Regime Chosen: Ms. Priya opts for the old tax regime to claim deductions.
• Patient: Father, aged 68 (Senior Citizen).
• Disease: Parkinson's Disease (A specified neurological disease).
• Total Medical Expenses Incurred (FY 2025-26): ₹2,20,000.
• Amount Reimbursed from Health Insurance: ₹75,000.

Calculation of 80DDB Deduction:

1. Applicable Limit: Since the patient is a senior citizen (68 > 60), the maximum deduction limit is ₹1,00,000.
2. Net Expenditure: This is the total expense minus any reimbursement.
   • Net Expenditure = ₹2,20,000 - ₹75,000 = ₹1,45,000.
3. Eligible Deduction: The deduction is the lower of the Net Expenditure and the Applicable Limit.
   • Lower of (₹1,45,000) and (₹1,00,000).

Ms. Priya can claim a deduction of ₹1,00,000 under Section 80DDB in her income tax return for AY 2026-27.

Common mistakes

1. Claiming under the New Tax Regime: The biggest mistake is assuming this deduction is available by default. It is only allowed under the old tax regime.
2. Forgetting the Specialist's Prescription: A prescription from a general practitioner is not sufficient. You must get it from a specialist as defined in the rules, in the prescribed Form 10-I.
3. Ignoring Reimbursements: Failing to reduce the claim amount by any money received from an insurer or employer can lead to an incorrect claim and potential tax notices.
4. Claiming for Non-Specified Diseases: The deduction is strictly limited to the diseases listed in Rule 11DD. Expenses for other serious illnesses are not covered.
5. Confusing 80DDB with 80D or 80DD: Section 80D is for health insurance premiums, while Section 80DD is for the maintenance of a dependant with a disability. Section 80DDB is exclusively for the treatment cost of specified ailments.

Frequently asked questions

H3: Who is considered a 'dependant' for Section 80DDB?

For an individual taxpayer, a 'dependant' refers to their spouse, children, parents, and brothers/sisters who are wholly or mainly dependent on the individual for their support and maintenance. The dependant does not need to be financially non-earning, but their primary support must come from the taxpayer.

H3: Is a prescription in Form 10-I mandatory?

Yes, obtaining a prescription from a qualified specialist is a mandatory requirement as per the Income-tax Act. While you do not submit it with your return, it is the primary evidence required to substantiate your claim if the Income Tax Department initiates an inquiry or scrutiny.

H3: Can I claim this deduction for expenses incurred abroad?

Yes. The location of the treatment does not affect eligibility. As long as the taxpayer is a resident of India, they can claim the deduction for expenses incurred on the treatment of a specified disease, whether the treatment took place in India or in another country.

H3: What is the difference between Section 80DDB and Section 80DD?

Section 80DDB provides a deduction for the expenditure on medical treatment of specified diseases. In contrast, Section 80DD provides a flat deduction (not based on actual expenses) for the maintenance, including medical treatment, of a dependant with a disability as defined in the Persons with Disabilities Act, 1995.

H3: Do I need to submit the actual medical bills with my ITR?

No, you are not required to submit any physical or digital copies of medical bills or prescriptions when you file your income tax return. However, it is your legal responsibility to preserve these documents carefully. The assessing officer may ask for them to verify your claim during an assessment or scrutiny proceeding.
