New Income Tax Bill 2025: All You Need to Know

Income Tax Act 2025: Full Guide to New Sections, Slabs & Changes (1961 vs 2025 Mapper) | KDK Software

India’s Income Tax Act, 1961 survived over 60 Finance Acts, 19 standalone amendment bills, and four thousand-odd individual changes before anyone decided. Clearly, enough was enough. The final state of the act was not only confusing and ambiguous, but needlessly inefficient. Finally, the Income Tax Act, 2025 was introduced by the Lok Sabha on 13 February 2025. Now this new act is not a new tax law so much as a rebuilt one. Same charge to tax, same rates, same deductions. What’s changed is everything around it: the structure, the language, the cross-references, and the sheer navigability of the statute.

It takes effect from 1 April 2026. Until then, the 1961 Act governs, fully, without exception.

This guide is written for practitioners and assumes you know what basic terms like TDS is. It won’t explain what an assessment year is, but it will tell you that the term no longer exists.

Why Income Tax Act 1961 Replaced by 2025 Act

The honest answer as to why Income Tax Act 1961 Replaced by the New Income Tax Act 2025, is that it had become genuinely difficult to use. Not difficult in the way complex legislation sometimes is, difficult in the way something becomes when it’s been patched repeatedly by people who weren’t talking to each other.

Section 10A, for instance, the special provision for units in free trade zones, became redundant after FY 2012-13. It stayed in the Act for over a decade, occupying space, appearing in searches, occasionally confusing junior staff. Multiply that across hundreds of similar provisions and you get a statute where finding the right answer requires knowing which answers to ignore.

The other issue was language. Long sentences. Provisos to provisos. Explanations that explained explanations. A competent professional could navigate it, but it took longer than it should, and the margin for error, especially in TDS compliance, was real.

The 2025 Act was CBDT’s attempt to fix the statute without touching the policy. Whether it fully succeeds will take a few years of litigation to answer. But the structural improvement is undeniable.

The Select Committee’s role here was more than ceremonial. It submitted 285 recommendations, 84 substantive, 201 drafting corrections, and several of them plugged genuine errors in the original Bill. A few of those matter a lot in practice.

Key Changes by the Committee in Income Tax Bill 2025

The original February 2025 Bill had problems. Some were drafting slippages; some were substantive errors that would have created real compliance headaches. Here’s what got corrected before the final version was passed:

Standard deduction under the new regime was raised from ₹50,000 to ₹75,000 and is now codified in the Act itself, not just the Finance Act. Minor distinction, but it matters for legislative stability.

Anonymous donation provisions (Clause 337) were wrong in the original Bill. The exemption from the 30% anonymous donation tax applied only to purely religious trusts, which isn’t what old Section 115BBC said. The Select Committee restored the correct position: both purely religious and religious-cum-charitable trusts are exempt. If you advise multi-purpose religious institutions, this was the most consequential fix in the entire exercise.

“Receipts” vs. “income” in Clause 335, the original Bill used the word “receipts” in NPO provisions where it should have said “income.” Left uncorrected, this would have exposed gross inflows (including pass-throughs and corpus) to tax. It’s corrected now, but it illustrates how much rode on the Select Committee’s review.

Nil/Lower TDS certificate mechanism was missing from the original Bill entirely. The Select Committee put it back. Without it, there would have been no statutory basis for the Form 13 process that many businesses and professionals rely on to manage cash flows.

Pre-construction interest on house property loans is now explicitly available for both self-occupied and let-out or deemed let-out properties. This was interpretively disputed under the old Act; it’s settled in the new one.

Key Changes From Income Tax Act 1961 to Income Tax Act 2025

 “Tax Year” Replaces Previous Year and Assessment Year (Section 3)

Section 3 of the new Act eliminates both terms and replaces them with a single unified concept: the Tax Year, running from 1 April to 31 March.

This sounds simple. In practice, it removes an enduring source of confusion, in client communications, in notices, in return forms, where references to “AY 2024–25” or “PY 2023–24” created regular mismatches. Anyone who has spent time explaining to a client why their FY 2023–24 income is assessed in AY 2024–25 will appreciate why collapsing this into a single reference period is overdue.

The TDS/TCS Consolidation

Under the 1961 Act, TDS provisions ran from Section 192 to Section 194T, more than 60 separate sections, each with its own format, thresholds, and exceptions. Cross-referencing them was a routine source of deductor error and audit exposure.

The 2025 Act consolidates all of this into three sections. Section 392 covers salary TDS, Section 393 covers TDS across three structured tables, residents, non-residents, and any person, with rates, thresholds, and conditions in a single readable format. Section 394 does the same for TCS. The number of TDS/TCS tables has actually increased, which sounds counterintuitive until you realise that more granular tables, clearly structured, are easier to work with than fewer sections that require you to read through multiple provisos to find the applicable rate.

For deductors, compliance teams, and auditors signing TDS certificates, this alone meaningfully reduces lookup time and error risk.

The Scale of Reduction

The 1961 Act had 819+ sections. The 2025 Act has 536, organised into 23 chapters and 16 schedules. Around 1,200 provisos and 900 explanations have been removed, absorbed into plain language or simply dropped where they were redundant. Total legislative volume is down roughly 40%.

The chapter structure is worth knowing because the new Act’s organisation is deliberately more logical than the old one’s, related provisions sit together rather than being scattered across the statute.

Capital Gains

The capital gains regime is preserved intact but reorganised across dedicated clauses. Clause 67 defines capital gains; Clauses 196–198 split out the tax treatment across short-term equity, long-term non-equity, and long-term equity assets respectively. Nothing substantively new here for domestic transactions.

Virtual Digital Assets are now formally recognised as taxable capital assets, with an expanded definition covering any asset holding value in digital form via cryptographic ledger systems. This gives VDA taxation a clearer statutory basis than it had under the 1961 Act’s additions.

Faceless Administration Gets a Statutory Footing

Section 532 authorises the Central Government to design administration schemes aimed at eliminating human interface and optimising resources. Previously, the faceless assessment and appeal framework rested on scheme-based authority. It now has a direct statutory basis, a more durable foundation for what has become a central feature of how the department operates.

The Act also introduces a formal definition of “Virtual Digital Space”, email servers, cloud storage, social media, online trading accounts, websites holding asset ownership records, which is the legislative architecture enabling digital enforcement and survey operations going forward.

Income Tax Act 2025 : Slabs

No changes. The Finance Act 2025 slabs are carried across as-is.

Refund Provisions: Chapter XX (Sections 431–438)

The refund provisions now sit in a dedicated chapter rather than being distributed across the statute. The mechanics are unchanged, a refund arises when total taxes paid (TDS, advance tax, self-assessment tax) exceed the assessed liability, but a few things are worth flagging.

TDS refunds are now available on belated returns as well as timely ones. This is a change that will matter for clients who missed the due date and assumed they’d lost the refund claim.

Interest on delayed refunds runs at 0.5% per month (or part thereof) is granted. No interest is payable where the refund is less than 10% of total tax liability.

Under Section 437, outstanding demands can be set off against refunds before the balance is paid out. Before advising clients on expected refund timelines, it’s worth checking the demand register, an unsatisfied demand from three years ago can quietly absorb a current-year refund.

Impact  on the Assesse

Income Tax Act 2025 for Salaried

All salary provisions, HRA, gratuity, leave encashment, perquisites, are now consolidated rather than scattered. The ₹75,000 standard deduction is in the Act. Non-employees (pensioners not drawing salary) can claim the full commuted pension deduction without restriction. Simplified return forms are expected before April 2026.

House Property: Pre-Construction Interest Deductible

The 30% standard deduction on Net Annual Value stays. Pre-construction interest is deductible for both self-occupied and let-out or deemed let-out properties, explicitly, this time. Vacant commercial property valuation disputes should reduce under clearer rules.

Income Tax Act 2025 Changes for Businesses and LLPs

LLPs get clearer inter-activity loss set-off provisions and a cleaner AMT framework. Under the presumptive scheme (Section 63), businesses with turnover under ₹10 crore and cash receipts below 5% are exempt from maintaining books and undergoing tax audit, a meaningful compliance reduction for mid-sized clients. Faceless assessments now have statutory authority rather than just scheme authority.

New Income Tax Changes for Charitable Trusts and NPOs

Everything previously scattered across Sections 11, 12A, 80G, and related sections is now in a single chapter. Anonymous donations are taxed at 30% (Clause 337), with the Select Committee correction restoring the exemption for religious-cum-charitable trusts alongside purely religious ones. The “income” fix in Clause 335 is quietly important: gross receipts won’t be taxed, which is what the law always intended.

What Hasn’t Changed

Tax rates are unchanged. The structure of assessments, appeals, and penalties will feel familiar. The 1961 Act continues to govern all periods up to 31 March 2026, no retrospective reach. Deductions and exemptions legitimately claimed for FY 2025–26 and earlier remain valid; the new Act doesn’t reopen them.

Frequently Asked Questions

What is the New Income Tax Bill 2025? 

The New Income Tax Bill 2025 is the legislation that replaced the ruling Income Tax Act of 1961. Now formally enacted as the Income Tax Act, 2025, it comes into effect on 1 April 2026. The good news is that nothing substantive has changed, the rates, deductions, and exemptions are all staying the same. The only major difference is how the law is written and organised, which is considerably cleaner than before.

Was the Bill passed in Lok Sabha? 

Yes, initially presented in February 2025, the New Income Tax Bill 2025 passed in the Lok Sabha on 11 August 2025. It then later got accepted in the Rajya Sabha the following day and received Presidential assent on 21 August 2025.

Where can I download the official PDF?

The Gazette-notified Act is available at egazette.gov.in/WriteReadData/2025/265620.pdf.

What’s the new income tax bill 2025 summary in one line? 

The one line summary of the New Income Tax Act 2025 is 536 sections, 23 chapters, 16 schedules. Same tax, simpler statute. April 2026.

How do refunds work under the new Income Tax 2025 Act? 

Income tax act 2025 refund work quite the same way they always have. If the taxes you’ve paid exceed your actual liability, the refund is claimed automatically when you file your ITR. One notable addition though is that belated filers can now claim TDS refunds as well. Interest still runs at 0.5% per month if the refund is delayed beyond a year, and any outstanding demands will be adjusted against your refund before it’s released, more details on the refund can be found on the Section 437.

Have tax rates changed? 

No, they haven’t. The Finance Act 2025 slabs continue to apply as they are both for old and new regimes. This means, no tax up to ₹12 lakh under the new regime, or ₹12.75 lakh if you’re a salaried individual.

When does the new Act take effect? 

The New Income Tax Bill 2025 takes effect on 1 April 2026. Anything up to 31 March 2026 is still governed by the Income Tax 1961 Act, so there’s no immediate disruption.

What’s the most significant structural change for practitioners?

In day-to-day practice, the TDS consolidation under Section 393 will probably be felt the most. The Tax Year change under Section 3 is also worth noting for practitioners, it finally resolves a long-running source of confusion around year references. If you work with NPOs or trusts, the Select Committee corrections to those provisions are among the most important changes to get across to your clients.

Does the new Act affect pending assessments or litigation? 

No. If an assessment, appeal, or proceeding relates to a period under the 1961 Act, it stays under the 1961 Act. The 2025 Act doesn’t go back in time.
