What is Section 80DDB Deduction for Specified Diseases?

Under Section 80DDB of the Income Tax Act, 1961 (and corresponding Section 128 of the Income-tax Act, 2025), individual taxpayers and HUFs are entitled to claim tax deductions for actual medical expenditures incurred for the medical treatment of prescribed critical illnesses suffered by the taxpayer or their dependent family members (spouse, children, parents, and siblings).

Diseases Covered under Rule 11DD

Section 80DDB covers medical treatments for specified diseases notified in Rule 11DD:

  • Neurological Diseases (Dementia, Parkinson's disease, Motor Neuron Disease, Chorea);
  • Malignant Cancers;
  • Full Blown Acquired Immuno-Deficiency Syndrome (AIDS);
  • Chronic Renal Failure; and
  • Hematological disorders (Hemophilia and Thalassaemia).

Statutory Deduction Limits

Patient Age Category Maximum Statutory Deduction Limit
Non-Senior Citizen (Below 60 Years) Up to ₹40,000
Senior Citizen (60 Years and Above) Up to ₹1,00,000

Mandatory Adjustment for Insurance Claims

The statute explicitly mandates that the qualifying deduction must be reduced by any reimbursement received from an insurance company or employer. If an employee incurs ₹1,00,000 for cancer treatment and receives an insurance settlement of ₹60,000, the allowable Section 80DDB deduction is ₹1,00,000 − ₹60,000 = ₹40,000.

Frequently Asked Questions (FAQs)

1. Is a certificate from a government hospital doctor mandatory?

Following amendments to Rule 11DD, patients are no longer required to obtain certificates exclusively from government hospitals. A prescription from a private specialist doctor holding a recognized DM or M.Ch qualification is fully valid.

2. Can Section 80DDB be claimed alongside Section 80D?

Yes. Section 80D pertains to health insurance premiums and CGHS subscriptions, whereas Section 80DDB pertains to actual medical treatment expenses for specified critical illnesses.

Statutory Authority: Section 80DDB, Income Tax Act, 1961 read with Rule 11DD / Section 128, Income-tax Act, 2025.
