Two of the most underclaimed deductions in the Income Tax Act relate to disability and serious illness — Section 80DD for taxpayers supporting a dependent with a disability, and Section 80DDB for the cost of treating specified critical diseases. Both offer substantial fixed deductions, but require specific certificates that many taxpayers don't realize they need to obtain. Here's how each works.
Section 80DD: Deduction for a Dependent with Disability
Section 80DD allows a deduction to a resident individual or HUF who has incurred expenditure on the medical treatment, training and rehabilitation of a dependent with a disability, or has deposited an amount under an approved scheme (e.g., LIC or other insurer schemes) for the maintenance of such a dependent.
| Disability Level | Deduction Amount (Fixed) |
|---|
| Disability (40% or more but less than 80%) | ₹75,000 |
| Severe disability (80% or more) | ₹1,25,000 |
⚠ This is a FIXED deduction, not based on actual expenditure. Even if you spent less than ₹75,000/₹1,25,000 on the dependent's care during the year, you can claim the full fixed amount, as long as the disability certificate and other conditions are met. Conversely, even if you spent more, you cannot claim above these fixed limits under 80DD.
Who Qualifies as a 'Dependent' Under 80DD?
- For an individual: spouse, children, parents, or siblings (brothers/sisters) who are dependent on the individual and have not claimed deduction under Section 80U for themselves
- For an HUF: any member of the HUF
Documentation for 80DD
- A medical certificate in the prescribed form (Form 10-IA for certain conditions, or certificate from a government hospital/specified specialist) certifying the disability and its percentage
- For severe disability, the certificate must confirm 80% or more disability
- If a deposit was made under an approved insurance scheme, proof of such deposit and the policy/scheme details
Section 80DDB: Medical Treatment of Specified Diseases
Section 80DDB allows a deduction for expenditure actually incurred on the medical treatment of specified diseases or ailments for the taxpayer themselves or a dependent. Unlike 80DD, this deduction is based on actual expenditure, subject to a cap.
| Category | Maximum Deduction |
|---|
| Taxpayer or dependent below 60 years | ₹40,000 or actual expenditure, whichever is lower |
| Taxpayer or dependent who is a senior citizen (60+ years) | ₹1,00,000 or actual expenditure, whichever is lower |
Which Diseases Are 'Specified' Under 80DDB?
Rule 11DD prescribes the list, which broadly includes:
- Neurological diseases with disability level of 40% and above (dementia, motor neuron disease, Parkinson's disease, etc.)
- Malignant cancers
- AIDS (Acquired Immuno-Deficiency Syndrome)
- Chronic renal failure
- Hematological disorders (hemophilia, thalassaemia)
ExampleSuresh (45 years) spent ₹1,50,000 on his elderly father's (72 years, a dependent) chronic renal failure treatment. Since the father is a senior citizen, the cap is ₹1,00,000. Suresh can claim ₹1,00,000 under Section 80DDB, even though actual expenditure was ₹1,50,000.
Documentation for 80DDB
A prescription from a specialist doctor (as specified — the rules previously required certificates only from government hospital specialists, but this has been relaxed to allow prescriptions from specialists in private hospitals as well, subject to specified qualifications) confirming the disease and the patient's details is required. Keep this prescription along with bills/receipts of actual expenditure incurred.
Important: Reduce by Insurance/Reimbursement Received
For 80DDB, if you received any amount from an insurer or employer towards the medical treatment (insurance claim, reimbursement), the deduction is restricted to the expenditure actually incurred by you, net of such reimbursement.
Old Regime vs New Regime
Both Section 80DD and Section 80DDB deductions are NOT available under the new tax regime. They can only be claimed if you opt for the old tax regime.
Frequently Asked Questions
Can I claim both Section 80DD (for my dependent's disability) and Section 80U (for my own disability) in the same year? ▼
Yes, these are independent deductions for different persons — Section 80DD is for expenditure on a DEPENDENT with a disability (spouse, children, parents, siblings, or HUF members), while Section 80U is for the TAXPAYER's OWN disability. If both you and a dependent (say, your child) have qualifying disabilities, you can potentially claim 80U for yourself and 80DD for your dependent child in the same year, provided all conditions and documentation requirements are separately met for each.
I spent only ₹40,000 on my disabled dependent's care this year, but the law allows ₹75,000 for 40-79% disability. Can I still claim ₹75,000? ▼
Yes. Section 80DD provides a FIXED deduction of ₹75,000 (for 40% to less than 80% disability) or ₹1,25,000 (for 80% or more disability), regardless of the actual amount spent during the year. As long as you hold a valid disability certificate confirming the relevant disability percentage and the dependent meets the definition under the section, you can claim the full fixed amount even if actual expenditure was lower.
Is Section 80DDB available if I opt for the new tax regime? ▼
No. Both Section 80DD (dependent disability) and Section 80DDB (medical treatment of specified diseases) are deductions under Chapter VI-A that are NOT available under the new tax regime (Section 115BAC). If you want to claim these deductions, you must opt for the old tax regime when filing your return.
