ITR-4 Deductions Guide: Documents You Need to Claim Tax Benefits for AY 2026-27

The Income-Tax Department has officially released the ITR-4 form, commonly known as the Sugam form, for Assessment Year (AY) 2026-27. The form is designed for resident individuals, Hindu Undivided Families (HUFs), and eligible firms opting for presumptive taxation, provided their annual income does not exceed ₹50 lakh.

One of the most important aspects of filing an income tax return is correctly claiming eligible deductions. While many taxpayers are familiar with tax-saving investments, fewer understand the documentation and information required to successfully claim these deductions in the ITR-4 form.

This comprehensive ITR-4 form deductions guide explains the key documents, details, and changes taxpayers should know before filing their returns.

Who Can File the ITR-4 Form?

The ITR-4 form can be used by taxpayers who earn income through:

• Business income under presumptive taxation schemes.
• Professional income under presumptive taxation provisions.
• Salary income.
• Pension income.
• Income from up to two house properties.
• Income from other sources.
• Long-term capital gains not exceeding ₹1.25 lakh.

Taxpayers with more complex income structures may need to use other return forms.

Why Documentation Matters for Tax Deductions

Claiming deductions is no longer simply about entering an amount in the tax return.

The Income-Tax Department increasingly requires taxpayers to provide supporting details that help verify deductions and reduce filing discrepancies.

Providing accurate information can:

• Prevent processing delays.
• Reduce the likelihood of notices.
• Improve compliance accuracy.

Eligible investments and payments include:

• Public Provident Fund (PPF).
• Employee Provident Fund (EPF).

Maintaining digital copies of supporting records is advisable.

Claiming Deductions Under Section 80CCD and 80CCD(1B)

For these deductions, taxpayers must provide:

Failure to correctly enter PRAN information may delay processing or create mismatches in tax records.

Key Changes Introduced in ITR-4 for AY 2026-27

The latest version of the ITR-4 form includes several notable changes.

Eligible taxpayers can now report income from up to two house properties under ITR-4.

This change provides greater flexibility for individuals with multiple residential properties.

2. New Field for Unrealised Rent

A dedicated field has been introduced for reporting 'rent which cannot be realised.'

This update may benefit property owners dealing with unrecovered rental income.

3. Simplification of Foreign Retirement Reporting

The requirement to report certain foreign retirement benefit details has been removed.

This simplifies compliance for eligible taxpayers with overseas retirement-related income arrangements.

Filing Deadlines Taxpayers Must Know

Taxpayers should carefully monitor filing deadlines to avoid penalties and interest.

Important dates include:

Early filing is generally recommended to avoid last-minute technical issues and ensure faster processing.

Common Mistakes While Claiming Deductions

Many taxpayers lose deductions due to avoidable filing errors.

Common mistakes include:

• Incorrect policy numbers.
• Wrong PRAN details.
• Missing donation receipts.
• Claiming ineligible deductions.
• Entering incorrect deduction amounts.
• Failure to maintain supporting records.

Reviewing deduction schedules before submission can significantly reduce errors.

Expert View: Why Taxpayers Must Prepare Early

Tax experts emphasize that successful tax filing increasingly depends on accurate documentation rather than simply estimating deduction amounts.

According to finance journalists and tax professionals covering the latest ITR changes, taxpayers should organize deduction-related documents throughout the financial year rather than waiting until the filing deadline approaches.

This approach helps reduce compliance risks while ensuring maximum utilization of available tax benefits.

What Taxpayers Should Do Next

Before starting the ITR-4 filing process, taxpayers should:

1. Gather investment proofs.
2. Verify policy numbers.
3. Confirm PRAN details.
4. Review donation receipts.
5. Check house property information.
6. Download relevant financial statements.
7. Reconcile deductions with Form 26AS and AIS where applicable.

Completing these steps beforehand can make filing smoother and more accurate.

Conclusion

The updated ITR-4 form for AY 2026-27 introduces several important compliance requirements and reporting changes. While the filing process remains relatively straightforward for taxpayers under the presumptive taxation scheme, claiming deductions now requires careful attention to documentation and supporting information.

Understanding the requirements for Section 80C, Section 80CCD, and other deduction categories can help taxpayers maximize tax savings while ensuring compliance with Income-Tax Department guidelines. As filing deadlines approach, early preparation remains the best strategy for a stress-free and accurate return filing experience.
