Section 80DDB of Income Tax Act – Deduction Limit and Diseases Covered

Section 80DDB offers genuine financial relief for families managing the treatment cost of serious illnesses — but the deduction requires precise documentation, including a specialist certificate meeting exact criteria.

Section 80DDB is one of the deductions available under Section 80 of the Income Tax Act, aimed at easing the financial burden of serious illnesses. Individuals and HUFs can claim a deduction on expenses incurred for treating specific diseases listed under Rule 11DD.

Key overview

• Available to resident individuals and HUFs only — cannot be claimed by companies, partnership firms, or other entities
• Covers actual medical expenses for specified diseases like cancer, AIDS, chronic renal failure, Parkinson's disease, and certain neurological disorders
• Can be claimed for the taxpayer's own treatment or for a dependent family member
• If treatment costs are covered by insurance or reimbursed by the employer, the reimbursed amount must be deducted from the claimable amount
• The taxpayer must be a resident of India to be eligible

For section 80ddb, the specialist’s prescription is the primary document; you do not submit it with your ITR, but must retain it.

• 80ddb certificate requirement: Specialist prescription confirming the disease, patient details and doctor’s credentials, as prescribed under Rule 11DD.
• All medical bills and receipts for treatment expenses.
• Disability certificate from the prescribed medical authority for neurological diseases involving 40% or more disability.
• Insurance or employer reimbursement statement to calculate the adjusted claimable amount.
• No government form is required; Form 10-I has been abolished.

Keep these documents safely as evidence in case the deduction is reviewed by the tax authorities.

Section 80DDB deduction can be claimed by resident individuals and Hindu Undivided Families (HUFs) for medical treatment of self or eligible dependants for specified diseases. Non-resident individuals are not eligible. The section 80DDB deduction eligibility is as follows:

The treatment must relate to a specified disease or ailment, and the taxpayer must obtain the required prescription from the appropriate specialist. The prescription includes details such as the patient's name and age and a description of the disease or ailment; disability certification is also relevant where applicable. The deduction is restricted to the lower of the actual amount spent and the applicable statutory limit.

Worked example: If an individual spent Rs. 80,000 in FY 2024-25 treating a specified illness and received Rs. 30,000 from insurance, they can claim only Rs. 10,000 (Rs. 40,000 minus Rs. 30,000). For a senior citizen in the same situation, the claim would be Rs. 70,000 (Rs. 1,00,000 minus Rs. 30,000).

*Note: Neurological diseases require a certified disability level of 40% or above.

The list is not exhaustive — other diseases may be included based on disability severity and specialist certification, per Rule 11DD.

Insurance reimbursement reduces the section 80ddb deduction claimable for eligible medical expenses, so only the unreimbursed amount can generally be claimed, subject to the applicable limit.

• For a non-senior citizen who spends Rs. 60,000 on treatment and receives Rs. 30,000 from an insurer, the claimable deduction is Rs. 10,000 (Rs. 40,000 limit minus Rs. 30,000 reimbursement). If reimbursement is Rs. 50,000 against the Rs. 40,000 limit, no deduction is available.
• For a senior citizen who spends Rs. 60,000 and receives Rs. 50,000 from an insurer, the claimable deduction is Rs. 10,000 (Rs. 60,000 actual expense minus Rs. 50,000 reimbursement, within the Rs. 1,00,000 limit). Thus, reimbursement directly reduces the amount claimable under Section 80DDB.

Section 80DD allows deductions for the care, support, and maintenance of a dependent family member with a permanent disability, including rehabilitation and training expenses. Section 80DDB relates specifically to expenses actually incurred for treating specific serious illnesses such as cancer or kidney failure. Deductions under 80DD are more regular and tied to long-term disability care, while 80DDB depends on active treatment of specified medical conditions.
