Tax Deductions for Medical Expenses and Disability: Sections 80DDB, 80DD, and 80U Explained (AY 2026-27)
Claim tax deductions up to Rs 1.25 lakh for medical treatment of specified diseases and disability under Sections 80DDB, 80DD, and 80U for AY 2026-27.
Beyond Section 80D for health insurance premiums, Indian income tax law provides three additional deductions specifically for taxpayers dealing with serious medical conditions or disability. These are Sections 80DDB, 80DD, and 80U — and they are among the most underused deductions in the entire Income Tax Act.
If you or a family member is undergoing treatment for a specified disease like cancer, a neurological condition, or chronic renal failure — or if you or your dependent has a disability — you may be eligible for significant tax relief. Here's a complete guide for AY 2026-27.
Section 80DDB: Deduction for Treatment of Specified Diseases
Section 80DDB allows you to claim a deduction for the actual amount spent on the medical treatment of certain specified diseases — for yourself or a dependent family member.
Who Can Claim?
Only resident individuals and Hindu Undivided Families (HUFs) can claim this deduction. NRIs are not eligible.
You can claim the deduction for medical treatment of:
- Self
- Spouse
- Children
- Parents
- Siblings (for HUFs: any member of the HUF)
What Are the Specified Diseases?
The list of diseases eligible under Section 80DDB is defined in Rule 11DD of the Income Tax Rules:
| Disease Category | Examples |
|---|---|
| Neurological diseases (where disability is 40%+) | Dementia, dystonia musculorum deformans, motor neuron disease, ataxia, chorea, hemiballismus, aphasia, Parkinson's disease |
| Malignant cancers | All types of cancer |
| AIDS (Acquired Immuno-Deficiency Syndrome) | Full-blown AIDS |
| Chronic renal failure | Kidney failure requiring dialysis |
| Hematological disorders | Hemophilia, thalassemia |
This list is exhaustive — you cannot claim 80DDB for diseases not listed in Rule 11DD, even if they are expensive to treat.
How Much Can You Deduct?
| Taxpayer Category | Maximum Deduction |
|---|---|
| Individual below 60 years | Rs 40,000 |
| Senior citizen (60 years or above) | Rs 1,00,000 |
The deduction is for the actual amount spent on treatment, up to the limits above. If your employer or insurer reimburses any portion of the treatment cost, the reimbursed amount must be subtracted from your claim.
Example: Priya (aged 35) spends Rs 2,80,000 on chemotherapy for her mother. Her employer's group health insurance reimburses Rs 1,50,000. Priya can claim a deduction of Rs 40,000 under Section 80DDB — the actual unreimbursed expense (Rs 1,30,000) exceeds the cap, so the maximum of Rs 40,000 applies.
If Priya's mother were a senior citizen, the cap would increase to Rs 1,00,000, and Priya could claim the full Rs 1,00,000.
What Documentation Do You Need?
You must obtain a prescription from a specialist doctor working in a government or private hospital. This prescription should be in Form 10-I and must certify that the patient is suffering from one of the specified diseases.
For neurological diseases specifically, the specialist must be a neurologist holding a Doctorate of Medicine (DM) in Neurology. For cancer, it must be an oncologist. The certificate must include the doctor's name, registration number, qualifications, and the name and address of the hospital.
Keep this certificate safe — you don't need to submit it while filing your ITR, but you must produce it if the tax department asks.
Section 80DD: Deduction for Maintenance of a Disabled Dependent
Section 80DD is for taxpayers who have a dependent family member with a disability and incur expenses towards their medical treatment, training, or rehabilitation.
Who Can Claim?
Only resident individuals and HUFs can claim Section 80DD. The deduction is available when you incur expenses for:
- Spouse
- Children
- Parents
- Siblings
The dependent must have a disability as defined under the Persons with Disabilities Act, 1995 or the National Trust Act, 1999. This includes conditions like:
- Blindness and low vision
- Hearing impairment
- Locomotor disability
- Mental illness and intellectual disability
- Autism spectrum disorder
- Cerebral palsy
- Multiple disabilities
How Much Can You Deduct?
Unlike most deductions, Section 80DD provides a flat deduction regardless of the actual amount spent:
| Disability Level | Deduction Amount |
|---|---|
| Disability of 40% or more but less than 80% | Rs 75,000 |
| Severe disability of 80% or more | Rs 1,25,000 |
This means even if you spend Rs 10,000 on your dependent's treatment, you can still claim the full Rs 75,000 (or Rs 1,25,000) deduction. This is a significant advantage — the deduction is not limited by actual expenditure.
Example: Rajan's 22-year-old son has autism spectrum disorder, certified as 65% disability. Rajan spends Rs 45,000 per year on therapy sessions. Under Section 80DD, Rajan can claim the full Rs 75,000 flat deduction — not just the Rs 45,000 he actually spent.
Key Rules
- The dependent must not have claimed a deduction under Section 80U for themselves. You cannot double-claim — either the disabled person claims 80U, or the family member claims 80DD. Not both.
- If you have deposited money in a scheme like the LIC's Jeevan Aadhar or any scheme of the Unit Trust of India for the maintenance of the disabled dependent, that qualifies too.
- If the disabled dependent predeceases the taxpayer, any amount deposited in a maintenance scheme that is refunded gets taxed in the year of receipt.
What Documentation Do You Need?
You need a disability certificate from a medical authority — specifically, a civil surgeon or Chief Medical Officer of a government hospital. The certificate must be in Form 10-IA and should specify the nature and percentage of disability.
For conditions like autism, cerebral palsy, and intellectual disability, the certifying authority must be recognized under the National Trust Act.
Section 80U: Deduction for Self with Disability
Section 80U works like the self-version of Section 80DD. If you yourself have a disability, you can claim this deduction.
Who Can Claim?
Only a resident individual who is certified as having a disability. This section does not apply to HUFs — it is personal to the individual.
The disabilities covered are the same as Section 80DD (blindness, hearing impairment, locomotor disability, mental illness, intellectual disability, autism, cerebral palsy, etc.).
How Much Can You Deduct?
| Disability Level | Deduction Amount |
|---|---|
| Disability of 40% or more but less than 80% | Rs 75,000 |
| Severe disability of 80% or more | Rs 1,25,000 |
Just like 80DD, this is a flat deduction — no bills or proof of expenditure required. If you have the disability certificate, you get the deduction.
Example: Meera has a locomotor disability of 55%. She earns Rs 8,00,000 per year from salary. Under Section 80U, she can directly claim Rs 75,000 as a deduction from her gross total income — bringing her taxable income down to Rs 7,25,000 (before other deductions like 80C, 80D, etc.).
Documentation
The same Form 10-IA disability certificate from a medical authority is required. The certificate is valid for the period specified in it — for permanent disabilities, it may be issued with permanent validity. For conditions that may improve, you'll need to renew it periodically.
Quick Comparison: 80DDB vs 80DD vs 80U

|---|---|---|---|
| Purpose | Treatment of specified diseases | Maintenance of disabled dependent | Self with disability |
| Who claims | Individual / HUF | Individual / HUF | Individual only |
| For whom | Self or dependent | Dependent only | Self only |
| Deduction basis | Actual amount spent (capped) | Flat amount | Flat amount |
| Limit (general) | Rs 40,000 | Rs 75,000 | Rs 75,000 |
| Limit (senior / severe) | Rs 1,00,000 | Rs 1,25,000 | Rs 1,25,000 |
| Certificate | Form 10-I (specialist doctor) | Form 10-IA (medical authority) | Form 10-IA (medical authority) |
| Actual expense proof needed | Yes | No | No |
Important Rules That Apply to All Three Sections
Old Regime Only
All three deductions — 80DDB, 80DD, and 80U — are available only under the old tax regime. If you have opted for the new tax regime, you cannot claim any of these deductions. This is an important factor when choosing between the old and new tax regime — taxpayers with significant medical expenses or disability in the family may find the old regime more beneficial even at higher income levels.
Can You Claim Multiple Sections Together?
Yes, with some conditions:
- You can claim both 80DDB and 80DD if you have a dependent with a disability who also suffers from a specified disease. For example, if your child has cerebral palsy (eligible for 80DD) and also develops cancer (eligible for 80DDB), you can claim both deductions.
- You cannot claim both 80DD and 80U for the same person. If the disabled person is earning and files their own return, they should claim 80U. If the family member is claiming the dependent's expenses, they claim 80DD. Choose the one that gives the maximum tax benefit to the family overall.
- You can claim 80DDB for self and have a dependent claim 80DD for another family member — these are for different people and different purposes.
No Double Benefit with Insurance Reimbursement
For Section 80DDB specifically, any amount reimbursed by your employer or an insurance company must be deducted from the claim. The intent is to give relief for out-of-pocket expenses, not to provide a windfall on top of insurance coverage.
Sections 80DD and 80U don't have this restriction because they provide flat deductions unrelated to actual spending.
How to Claim These Deductions in Your ITR
When filing your income tax return for AY 2026-27:
- Choose the old tax regime — these deductions are not available under the new regime.
- In the deductions section of your ITR form (ITR-1, ITR-2, or ITR-3), navigate to the section for Chapter VI-A deductions.
- Enter the amount under the relevant section (80DDB, 80DD, or 80U) as applicable.
- Keep the medical certificates (Form 10-I or Form 10-IA) ready — you don't upload them during filing, but must produce them if the department requests.
49Tax's AI assistant can help you identify which of these deductions apply to your situation and ensure you claim the correct amounts when filing your return.
Actionable Takeaway
If you or a family member is dealing with a serious illness or disability, don't overlook Sections 80DDB, 80DD, and 80U. The combined tax savings can be substantial — up to Rs 2,65,000 in deductions if you're eligible for both 80DDB (Rs 1,00,000 for senior citizens) and 80DD or 80U (Rs 1,25,000 for severe disability) together. Start by getting the right medical certificates now, well before the filing deadline, since obtaining Form 10-I or Form 10-IA from a government hospital can take time.
