What is Section 80DDB?
Section 80DDB allows taxpayers to claim deductions for expenses incurred on medical treatment of specified diseases or ailments for themselves or their dependents. The objective is to provide financial relief to taxpayers burdened with high-cost treatments, including conditions like cancer, neurological disorders, and chronic renal failure. The deduction is available for both individual taxpayers and HUFs, subject to prescribed limits and conditions.
Who Can Claim Section 80DDB Deduction?
Eligible claimants include:
Individual taxpayers paying for their own treatment or treatment of dependents, such as spouse, children, parents, and siblings.
Senior citizens, aged 60 years or above, can claim higher deductions.
HUFs for medical expenses incurred for any member of the HUF.
The taxpayer must ensure that the expenses are not reimbursed by any insurance or employer benefits to claim the full deduction.
Specified Critical Illnesses Covered Under Section 80DDB
The deduction applies only to specific medical conditions, including:
Neurological disorders (e.g., Parkinson’s disease, multiple sclerosis)
Cancer
Chronic renal failure
AIDS/HIV
Hemophilia
Thalassemia
Other terminal or chronic illnesses specified by the Income Tax Department
The list of diseases is updated periodically, and the deduction applies strictly to treatments of these illnesses as certified by a specialist doctor.
Deduction Limits Under Section 80DDB
Section 80DDB of the Income Tax Act provides tax relief to individuals who incur expenses on medical treatment for specified diseases. The deduction limits under this section depend primarily on the age of the taxpayer. For individuals who are below 60 years of age, the maximum deduction allowed is up to ₹40,000 per financial year. This means that if a taxpayer spends money on treatment for themselves or for their dependents for eligible diseases, they can claim a deduction from their taxable income, but the total amount cannot exceed ₹40,000, even if the actual expenditure is higher.
For senior citizens, defined as individuals aged 60 years and above, the limit is significantly higher, with a maximum deduction of up to ₹1,00,000 per financial year. This higher limit acknowledges the increased medical expenses typically incurred by older taxpayers and provides them greater relief.
It is important to note that the deduction under Section 80DDB is allowed for expenses incurred not only for the treatment of the taxpayer themselves but also for the treatment of dependents such as children, spouse, or parents. However, the deduction cannot exceed the actual amount spent on the medical treatment in a given financial year, ensuring that taxpayers can only claim for genuine expenses.
This provision helps taxpayers manage the financial burden of serious medical conditions while also reducing their taxable income, encouraging timely treatment and care.
How to Claim Section 80DDB Deduction in Income Tax Return
Claiming a deduction under Section 80DDB of the Income Tax Act allows taxpayers to reduce their taxable income by the amount spent on medical treatment for specified diseases or ailments for themselves or specified relatives. To claim this deduction, the first step is to collect all relevant medical bills, invoices, and prescriptions related to the treatment of the illness. These documents serve as proof of expenditure and are necessary for accurately reporting the deduction.
Next, it is essential to obtain a certificate from a specialist doctor, using Form 10-I, which confirms the diagnosis of the specified disease and validates the medical expenditure. This certificate must be issued by a recognized specialist in the relevant field and should clearly state the nature of the illness.
While filing the Income Tax Return, taxpayers must enter the claimed amount in the section dedicated to Section 80DDB. It is important to ensure that the claimed deduction does not exceed the maximum limit prescribed under the law for the financial year.
Maintaining all supporting documents, including medical bills, prescriptions, and the doctor’s certificate, is crucial in case the Income Tax Department conducts scrutiny or requires verification of the claim.
Using platforms like TaxBuddy can simplify this process significantly. TaxBuddy ensures that Section 80DDB claims are entered accurately while filing the ITR, reducing the risk of errors, omissions, or audit issues, and helps taxpayers comply seamlessly with all legal requirements.
Medical Certificate Requirements for Section 80DDB
A valid medical certificate must include:
Name and age of the patient
Name and registration number of the specialist doctor
Diagnosis of the specified disease
Confirmation that the treatment is necessary
Signature and seal of the doctor
Without this certificate, the deduction claim may be disallowed by the Income Tax Department.
Out-of-Pocket Expenses and Reimbursements
Only expenses actually paid by the taxpayer or HUF, which are not reimbursed by insurance or employer benefits, qualify for the deduction. Payments made through insurance claims or company health benefits cannot be claimed under Section 80DDB. Proper documentation is essential to prove out-of-pocket expenses.
Section 80DDB Deduction for Dependents
The deduction can be claimed for dependent family members, including:
Spouse
Children
Parents
Siblings
Any dependent specified in the Income Tax Act
The expenses should be incurred directly by the taxpayer, and proper medical documentation must be maintained for the claim.
Is Section 80DDB Allowed in New Tax Regime?
Under the new tax regime, most exemptions and deductions are not allowed. Section 80DDB is not available under the new tax regime. Taxpayers wishing to claim this deduction must opt for the old tax regime, where deductions for medical expenses on specified critical illnesses are permitted.
Common Mistakes While Claiming Section 80DDB
While Section 80DDB of the Income Tax Act provides valuable relief for expenses incurred on medical treatment of specified diseases, taxpayers often make errors that can lead to scrutiny or rejection of their claims. One common mistake is claiming the deduction without submitting a proper medical certificate issued by a specialist doctor. The certificate must clearly mention the disease, its severity, and the treatment required; without this documentation, the claim can be disallowed.
Another frequent error is including non-specified diseases that are not listed under the approved diseases covered by Section 80DDB. Claiming deductions for conditions outside the specified list may result in rejection during assessment.
Taxpayers also sometimes exceed the prescribed deduction limits, either by misunderstanding the maximum allowed amount for themselves or for their dependents. Similarly, claiming expenses that have already been reimbursed by insurance or an employer is a common oversight, as these cannot be counted again under Section 80DDB.
Finally, misreporting dependent information, such as incorrect names, ages, or relationship details, can delay processing or trigger inquiries from the Income Tax Department. Paying attention to these details and following the prescribed rules ensures smooth processing and minimizes the risk of rejection or unnecessary scrutiny.
Practical Tips to Maximize Section 80DDB Benefits
Keeping all medical bills, prescriptions, and receipts organized is essential for claiming the Section 80DDB deduction efficiently. Maintaining a proper record of every expenditure related to the treatment of specified diseases ensures that you have all necessary documents ready in case the Income Tax Department requests verification. Digital copies of bills and prescriptions, arranged chronologically, can save time during filing and reduce the risk of missing any eligible expenses.
Ensure that the medical certificate is valid and signed by a qualified specialist recognized by the Income Tax Department. The certificate must include details of the patient, the medical condition, and the treatment being undertaken. Certificates that do not meet the prescribed format or are signed by general practitioners may be rejected, which can lead to disallowance of the deduction.
File returns under the old tax regime to claim Section 80DDB benefits, as the new tax regime does not allow most deductions. Selecting the correct regime ensures that you can legally maximize your tax savings while staying compliant with the law.
Using platforms like TaxBuddy can simplify the filing process by automatically guiding you through the deduction sections, validating inputs, and ensuring that all eligible expenses are claimed correctly.

Keeping a clear summary of each dependent’s medical expenses and cross-checking against limits can prevent unnecessary penalties and ensure accurate tax benefits.
