Extended ITR Filing Dates for Certain Taxpayers


Under the new income tax framework, non-audit taxpayers using ITR-3 and ITR-4 forms can now file returns until August 31, instead of the earlier July 31 deadline. However, ITR-1 and ITR-2 filers must adhere to the July 31 deadline. This extension provides extra time for taxpayers to compile accurate records.

Revised Return Deadline Updated


Taxpayers can now submit revised returns until March 31, giving more flexibility to correct mistakes. Additionally, filing after the due date is allowed without penalties until December 31, encouraging compliance without undue pressure.


Assessment Year Replaced With Tax Year


The term “assessment year” has been officially replaced by “tax year” under the new rules. This change simplifies the understanding of financial timelines, helping taxpayers clearly identify the year their income will be assessed.

TCS (Tax Collected at Source) Changes


Significant adjustments have been made to the TCS system:


  • Education and medical remittances under the Liberalised Remittance Scheme will now attract 2% TCS up to ₹10 lakh, down from 5%.
  • Foreign tourism packages will also see TCS reduced to 2%.
  • Other remittances will continue to attract a 20% TCS rate.

These changes reduce the financial burden for overseas education, medical expenses, and travel.

TDS Exemptions Expanded


The new rules exempt TDS on motor accident claims and travel allowances, providing relief to claimants and salaried taxpayers alike.

TAN Abolished for Non-Residents


Non-residents purchasing property no longer need a TAN. TDS can now be deposited through PAN-linked challans, simplifying property transactions for overseas investors.

Tax Exemptions on Pensions and Education


  • Armed Forces pensions will now be tax-free only for personnel who left service due to physical disabilities.
  • Education exemptions have been revised: ₹3,000 per student and hostel allowance up to ₹9,000.

These adjustments aim to align exemptions with current financial realities.


PAN Requirements Expanded


The new law makes PAN mandatory for high-value transactions, including:

  • Annual transactions exceeding ₹10 lakh
  • Vehicle purchases above ₹5 lakh
  • Hotel bookings of significant value
  • Property purchases exceeding ₹20 lakh

This enhances transparency and tracking of high-value financial activity.

Stock Market Rules Update


From April 1, Securities Transaction Tax (SST) rates will increase:

  • Futures trading: 0.02% → 0.05%
  • Option premiums: 0.10% → 0.15%
  • Option exercises: 0.15%
  • Share buybacks will also become more expensive for companies and investors

These changes reflect efforts to streamline taxation on stock market transactions and align with market growth.

The Income Tax Act 2025 introduces multiple financial rules changing from April 1, impacting ordinary taxpayers, non-residents, and investors alike. From extended ITR deadlines and revised TCS rates to mandatory PAN use and SST changes, staying informed is crucial to avoid penalties and optimise financial planning.
