Disability and illness deductions (80U / 80DD / 80DDB) (80U/80DD/80DDB)
Three separate deductions cover disability and serious illness, all old regime only. Section 80U is for a disabled individual claiming for themselves: a flat Rs 75,000 (Rs 1,25,000 for severe disability of 80% or more), regardless of what you actually spend. Section 80DD is the same flat amount for a taxpayer maintaining a dependant with a disability. Section 80DDB is different: it covers the actual cost of treating a specified illness (the Rule 11DD list, such as cancer, chronic renal failure or certain neurological conditions), up to Rs 40,000 (Rs 1,00,000 for a senior), reduced by any insurance reimbursement.

What this relief is, in plain English
The key distinction is flat versus actual. The two disability deductions, 80U for yourself and 80DD for a dependant you support, are flat amounts: Rs 75,000, or Rs 1,25,000 where the disability is severe (80% or more). You claim the flat amount whether your actual costs were nil or several lakh, no bills required, just a valid disability certificate (Form 10-IA). The illness deduction, 80DDB, works the opposite way: it reimburses actual treatment costs for a listed serious illness, capped at Rs 40,000 (or Rs 1,00,000 if the patient is a senior), and you subtract any amount an insurer or employer paid back. All three are old-regime only, so weigh them in the regime choice. This is general information, not advice for your situation.
How it works
80U: a flat deduction for yourself
A resident individual with a certified disability of 40% or more claims a flat Rs 75,000, rising to Rs 1,25,000 where the disability is severe (80% or more). It is independent of actual spending, you get the full amount regardless of what the disability costs you, on production of a valid certificate (Form 10-IA) from a prescribed medical authority.
80DD: the same flat amount for a dependant
Where you maintain a dependant (spouse, child, parent or sibling) with a disability, you claim the same flat Rs 75,000 or Rs 1,25,000, again independent of actual spend, covering their maintenance and medical care or a qualifying insurance scheme for them. 80U (claimed by the disabled person) and 80DD (claimed by a carer for that same person) cannot both be claimed for the same individual.
80DDB: actual cost of a specified illness
This covers the actual cost of treating a specified illness on the Rule 11DD list (including malignant cancers, chronic renal failure, full-blown AIDS, certain neurological conditions and specified haematological disorders), for yourself or a dependant. The deduction is the amount spent, capped at Rs 40,000 (Rs 1,00,000 if the patient is a senior citizen), reduced by any insurance or employer reimbursement, and supported by a specialist's prescription.
Who qualifies
- Resident individual or HUF (old regime)
- 80U: certified disability of the individual (Form 10-IA)
- 80DD: a dependant with a certified disability whom you maintain
- 80DDB: actual treatment of a Rule 11DD specified illness (specialist prescription)
- Not available under the new regime
Interactions with other reliefs
80U vs 80DD
Mutually exclusive for the same person: the disabled individual claims 80U, or a carer claims 80DD for them, not both
Section 80DDB
Separate from 80U/80DD and can be claimed alongside them (different basis, actual cost of illness)
Section 80D
Health-insurance premium (80D) is separate from illness-treatment cost (80DDB); both can apply
Common mistakes + audit triggers
- Thinking 80U/80DD require proof of spending (they are flat, no bills needed)
- Forgetting to net off insurance reimbursement from an 80DDB claim
- Both the disabled person (80U) and a carer (80DD) claiming for the same individual
- Expecting these deductions under the new regime (they are old regime only)
- Claiming 80DDB for an illness not on the Rule 11DD list
Worked example
Vikram, Jaipur - self-employed individual with a certified 80% disability, also funding a parent's cancer treatment (2026-27)
Vikram has a certified severe disability (80%), and during the year pays Rs 1,20,000 towards his senior father's cancer treatment, of which an insurer reimburses Rs 30,000.
Calculation: Under the old regime, Vikram claims a flat Rs 1,25,000 under Section 80U for his own severe disability, with no need to prove any spend, on his Form 10-IA certificate. Separately, for his father's cancer (a Rule 11DD specified illness, father a senior), he claims under Section 80DDB the actual cost capped at Rs 1,00,000, reduced by the Rs 30,000 reimbursement, so Rs 70,000. Total relief Rs 1,95,000. He confirms the old regime beats the new regime for his income before relying on it.
Statute reference: Income-tax Act 2025 ss.127-128 + s.154 (Income-tax Act 1961 ss.80DD/80DDB/80U) s.80U (self), s.80DD (dependant), s.80DDB (specified illness, Rule 11DD); Form 10-IA disability certificate.
