Why Consulting a Tax Consultant in Chennai Can Make Your ITR Filing Easier

Income Tax Return (ITR) filing season for Assessment Year (AY) 2026-27 is now underway, bringing several important updates that taxpayers must understand before filing their returns. From revised filing deadlines and updated ITR forms to new disclosure requirements, staying compliant has become more important than ever.

Whether you’re a salaried employee, freelancer, business owner, or investor, understanding these changes can help you avoid penalties, maximize eligible deductions, and ensure hassle-free filing. This is where an experienced tax consultant in Chennai can provide valuable guidance and help you file accurately.

In this comprehensive guide, we’ll explain the latest ITR changes for AY 2026-27, filing deadlines, eligibility criteria, and common mistakes to avoid.

What is AY 2026-27?

Assessment Year (AY) 2026-27 refers to the period during which income earned during Financial Year (FY) 2025-26 is assessed and taxed.

For example:

  • Income earned between April 1, 2025, and March 31, 2026
  • Filed during AY 2026-27

Even though the new Income Tax Act, 2025 has come into effect, returns for income earned during FY 2025-26 will continue to be filed under the existing framework. This has created some confusion among taxpayers, making professional assistance increasingly valuable.

Important ITR Filing Due Dates for AY 2026-27

The Income Tax Department has introduced different deadlines depending on the taxpayer category.

Salaried Individuals and Non-Audit Taxpayers

Due Date: 31 July 2026

Applicable for:

  • ITR-1 (Sahaj)
  • ITR-2

Business Owners and Professionals (Non-Audit Cases)

Due Date: 31 August 2026

Applicable for:

  • ITR-3
  • ITR-4

Tax Audit Cases

Transfer Pricing Cases

Due Date: 30 November 2026

Belated Return

Last Date: 31 December 2026

Revised Return

Last Date: 31 March 2027

Missing these deadlines can lead to penalties, interest liabilities, delayed refunds, and restrictions on claiming certain benefits.

Major Changes in ITR Forms for AY 2026-27

The government has notified updated ITR forms with several significant modifications.

1. ITR-1 Now Covers Two House Properties

Previously, taxpayers filing ITR-1 could report income from only one house property.

For AY 2026-27, eligible taxpayers can now report income from up to two house properties while continuing to use ITR-1, provided all other eligibility conditions are met.

This change benefits many salaried individuals who own a self-occupied home and an additional residential property.

2. New Unrealised Rent Disclosure

A new field has been introduced in:

  • ITR-1
  • ITR-3
  • ITR-4

This allows taxpayers to separately disclose unrealised rent from tenants who have defaulted on rental payments.

Property owners should carefully maintain supporting documentation to claim this benefit correctly.

3. Additional Address Reporting

The updated forms include provisions for reporting a secondary address.

This enhancement improves taxpayer identification and communication accuracy.

4. Expanded Reporting Requirements

Certain taxpayers, including professionals, business owners, and those with complex income structures, may need to provide more detailed disclosures than before.

An experienced tax consultant in Chennai can help ensure all required schedules and disclosures are completed accurately.

Choosing the Right ITR Form

One of the most common reasons for defective return notices is selecting the wrong ITR form.

ITR-1 (Sahaj)

Suitable for:

  • Salaried individuals
  • Pensioners
  • Income up to ₹50 lakh
  • Up to two house properties
  • Other income such as bank interest

ITR-2

Suitable for:

  • Capital gains income
  • Multiple house properties
  • Foreign assets or foreign income
  • Income exceeding ₹50 lakh

ITR-3

Choosing the wrong form may trigger notices from the Income Tax Department and delay processing.

Common ITR Filing Mistakes to Avoid

Many taxpayers receive notices simply because of avoidable filing errors.

Not Reconciling AIS and Form 26AS

Always compare:

  • AIS (Annual Information Statement)
  • Form 26AS

  • Bank statements

Any mismatch may attract scrutiny.

Ignoring Additional Income Sources

Taxpayers often forget to disclose:

  • Interest income
  • Capital gains

  • Rental income
  • Foreign income

Incomplete reporting can lead to penalties.

Claiming Incorrect Deductions

Ensure you have supporting proof for:

  • Section 80C investments

Missing the Filing Deadline

Late filing may result in:

  • Late fees
  • Interest liability
  • Delayed refunds
  • Loss of carry-forward benefits

Failing to Verify the Return

After submission, e-verification is mandatory. An unverified return is treated as not filed.

A professional tax consultant in Chennai can help with:

  • Correct ITR form selection
  • Tax planning
  • Deduction optimization

  • Own rental properties
  • Invest in stocks or mutual funds
