ITR-4 deductions guide: Documents you need to claim tax benefits for TY 2026-27

Filing taxes as a small business owner, consultant, or freelancer often brings a unique compliance challenge: balancing simplicity with optimal tax savings. The Income Tax Department designed ITR-4 (also known as Sugam) specifically to reduce accounting burdens for eligible small taxpayers.

The right ITR-4 deductions can reduce your taxable income and, in turn, your overall tax liability for Tax Year 2026-27. If you have paid life insurance premiums, contributed to NPS, bought health insurance, paid education-loan interest, made eligible donations or paid rent, some of these expenses may qualify for a deduction, depending on your tax regime and the conditions applicable to each provision.

For Tax Year 2026-27, these deductions are governed by the Income Tax Act 2025, which has introduced new section numbers for several provisions familiar under the earlier law. Each deduction also comes with its own eligibility requirements and documentation. Keeping the relevant receipts, certificates and payment records ready helps you claim the benefits correctly and substantiate them if required.

This ITR-4 deductions guide covers the limits that apply and the documents you need to keep ready before filing your return.

Which ITR-4 deductions can you claim for TY 2026-27?

The most relevant deductions for an ITR-4 taxpayer include:

Deduction	Income Tax Act 2025	What you can claim
Eligible investments and payments	Section 123	Up to ₹1.5 lakh, subject to the specified investments and payments
NPS contributions	Section 124	Eligible own/employer contributions, subject to the applicable limits
Agnipath contribution	Section 125	Eligible contribution to the Agniveer Corpus Fund
Health insurance and medical expenses	Section 126	Eligible health insurance premiums and specified medical expenses
Medical treatment of dependent with disability	Section 127	₹75,000; ₹1.25 lakh for severe disability, subject to conditions
Specified medical treatment	Section 128	Up to ₹40,000; ₹1 lakh for a senior citizen
Education-loan interest	Section 129	Eligible interest paid on a higher-education loan
Eligible home-loan interest	Sections 130/131	Available only for loans and properties meeting the statutory conditions
Electric-vehicle loan interest	Section 132	Up to ₹1.5 lakh, subject to the specified loan conditions
Eligible donations	Section 133	Deduction depends on the recipient and applicable percentage
Rent paid without HRA	Section 134	Up to ₹60,000 a year, if you don’t receive HRA from the employer
Disability deduction	Section 154	Deduction for an individual with a qualifying disability

The Income Tax Act 2025 substantially retains the familiar deduction framework but renumbers the provisions. For example, Section 123 carries the ₹1.5 lakh deduction for specified investments and payments, while Section 126 deals with health insurance and specified medical expenditure.

First, check your tax regime

This is the most important point before collecting documents. Under the default new tax regime, most Chapter VIII deductions are not available. In particular, Section 123 cannot be claimed under the new tax regime. The Income Tax Department’s guidance confirms that Section 123 is available only when the taxpayer is eligible to use the old tax regime.

For taxpayers with business or professional income, choosing the old regime also involves the prescribed option and filing requirements. Therefore, don’t assume that having made an eligible investment automatically means you can claim the deduction in ITR-4.

Some deductions continue to have specific treatment under the new regime. For example, eligible employer contributions to NPS under Section 124 can continue to qualify.

So, the right sequence follows this: Choose the applicable tax regime. Then, identify the deductions available under that regime. Collect the supporting documents and then enter the eligible amounts in ITR-4.

Section 123: Investments, insurance and other eligible payments

Section 123 is the new Act’s equivalent of the familiar Section 80C basket. An individual or HUF can claim up to ₹1.5 lakh for specified payments and investments listed in Schedule XV. These include qualifying payments such as:

• Life insurance premiums
• Provident Fund contributions
• Tuition fees
• Housing-loan principal repayment
• National Savings Certificate and specified small-savings investments
• Other investments and payments listed in the Schedule

The ₹1.5 lakh is an aggregate limit, not a separate ₹1.5 lakh for each investment.

Keep these documents ready:

• Life insurance premium receipts
• Policy document or policy number
• PF contribution statement
• NSC certificate or investment statement
• Tuition-fee receipts
• Home-loan certificate showing principal repayment
• Investment statements for eligible instruments
• Payment receipts or transaction records

The ITR-4 utility requires additional information for Section 123 claims, including the eligible amount and policy or document identification details.

Important: You don’t normally attach these receipts to your ITR. Keep them safely in case the Income Tax Department asks you to substantiate the claim.

Section 124: NPS contributions

Section 124 covers deductions relating to contributions to a pension scheme notified by the Central Government, including the NPS framework. It covers different types of contributions, including eligible employer contributions and the additional deduction available for an individual’s own contribution, subject to the conditions and limits in the section. The additional ₹50,000 NPS deduction continues under the new Income Tax Act.

Keep these documents ready:

• PRAN ID
• NPS contribution statement
• Transaction or contribution receipts
• Employer contribution details, if applicable
• Salary/TDS records where employer contribution is reported

The ITR-4 utility requires PRAN-related information for applicable NPS deductions.

Section 126: Health insurance and medical expenses

Section 126 covers eligible health insurance premiums, certain preventive health check-ups and specified medical expenditure. For an individual, the provision allows deductions for eligible health insurance covering the taxpayer and family and for parents, with the limits increasing where the relevant insured person is a senior citizen. It also provides for specified medical expenditure in cases involving senior citizens where the statutory conditions are met.

Documents to keep ready:

For health insurance	For eligible medical expenditure
Health insurance premium receipt Policy document Policy number Insurer’s name Proof of payment	Hospital or medical bills Prescriptions Payment receipts Evidence establishing the senior-citizen status, where relevant Insurance reimbursement details, if any

The ITR-4 utility specifically asks for the insurer’s name, policy number and health-insurance amount when claiming the deduction.

Section 127: Disability-related expenses for a dependent

If you are claiming a deduction for the maintenance, medical treatment, training or rehabilitation of a dependent with a disability, Section 127 may apply. The deduction is ₹75,000, increasing to ₹1.25 lakh for severe disability, subject to the statutory conditions.

Documents to keep ready:

• Disability certificate
• UDID details, where available
• Medical records, where relevant
• Proof of the dependent relationship
• PAN and Aadhaar details of the dependent, where required
• Details of the prescribed form filed for the claim

For specified disability claims, the ITR-4 utility requires information such as the nature and type of disability, dependent details, PAN/Aadhaar and the acknowledgement details of the applicable form.

Section 128: Treatment of specified diseases

Section 128 provides a deduction for eligible medical treatment of specified diseases. The deduction is limited to the amount actually paid or ₹40,000, whichever is lower. For a senior citizen, the limit increases to ₹1 lakh, subject to the conditions of the section.

Documents to keep ready

• Prescription from the specified medical specialist
• Medical bills
• Hospital bills
• Payment receipts
• Insurance reimbursement details, if applicable

The deduction must be reduced by amounts received from an insurer or reimbursed by an employer for the same treatment.

Section 129: Interest on an education loan

If you have taken an eligible loan for higher education for yourself or a specified relative, the interest actually paid during the tax year can qualify for deduction under Section 129. The deduction is available for the initial tax year in which interest is paid and the following seven tax years, or until the interest is fully paid, whichever is earlier.

Documents to keep ready:

• Education-loan interest certificate
• Loan account statement
• Loan sanction letter
• Lender’s name and details
• Proof of interest payment
• Details of the student and course, where required

The ITR utility requires information such as the lending institution, loan account number, sanction date, loan amount, outstanding amount and interest paid for applicable education-loan claims.

Sections 130 and 131: Certain home-loan interest deductions

The Income Tax Act 2025 retains deductions for interest on certain housing loans, but these provisions apply only to loans that satisfy specific statutory conditions.

Section 131 provides a deduction of up to ₹1.5 lakh for specified loans sanctioned between 1 April 2019 and 31 March 2022, subject to conditions including the value of the property and ownership requirements. Section 130 covers another specific category of housing loans and provides a deduction of up to ₹50,000, again subject to conditions relating to the loan and property.

Documents to keep ready

• Home-loan interest certificate
• Loan account number
• Loan sanction letter
• Date of sanction
• Original loan amount
• Outstanding loan balance
• Interest paid during the tax year
• Property details

Don’t claim these deductions merely because you have a home loan. Check whether the loan sanction date, property value and other statutory conditions match the relevant section.

Section 133: Donations to specified funds, institutions and organisations

The amount you can deduct depends on the category of recipient. Some donations qualify for 100% deduction, while others qualify for 50%, and certain donations are subject to the applicable percentage-of-income limit.
There is also an important payment condition: a donation exceeding ₹2,000 must not be paid in cash to qualify for deduction. For donations to eligible institutions, the claim is also subject to the information furnished by the recipient and the department’s verification process.

Documents to keep ready

• Donation receipt
• Name and address of the donee
• PAN of the donee, where applicable
• Registration/approval details of the institution
• Date and amount of donation
• Bank statement or payment proof

Don’t rely only on the receipt. Check that the organisation is eligible for deduction under Section 133.

Section 134: Rent paid when you do not receive HRA

Section 134 provides a deduction for certain taxpayers who pay rent for their residential accommodation but do not receive HRA. The deduction is subject to the statutory formula and is capped at ₹60,000 a year. The section also contains conditions relating to ownership of residential property and other circumstances.

For Tax Year 2026-27, the corresponding declaration is Form 31, which replaces the earlier Form 10BA. The Income Tax Department requires details such as the rented property’s address, rent paid, payment mode and landlord details.

Documents to keep ready

• Rent receipts
• Rent agreement, if available
• Bank statements or payment proof
• Landlord’s name and address
• Landlord’s PAN, where required
• Details of the rented property

Form 31 must be furnished along with the return, so do not leave this declaration until after filing the ITR.

Common mistakes when claiming ITR-4 deductions

Claiming deductions under the wrong tax regime: The most common mistake is assuming that every investment or payment qualifies for a deduction regardless of the regime chosen. For example, the ₹1.5 lakh deduction under Section 123 is not available under the new tax regime.

Claiming the same payment twice: An investment or expense should not be claimed under two different provisions for the same tax year.

Using a payment receipt without checking eligibility: A receipt proves that you paid something. It does not automatically prove that the payment qualifies for a deduction. Check the section’s conditions before entering the amount in ITR-4.

Ignoring the information required in the ITR: Some deductions require more than the amount paid. For example, ITR-4 requires policy/document identification details for Section 123, PRAN for applicable NPS deductions and insurer and policy details for Section 126.

Forgetting the separate form: If a deduction requires a prescribed form, filing the ITR without completing that form can prevent the claim from being allowed.

The objective behind the ITR-4 deductions guide is to claim deduction you are legally entitled to, with the records and information needed to support it.
