Income Tax Act 2025, Explained

What actually changes for you — and what doesn’t — now that India’s 64-year-old tax law has been rewritten.
13 MIN READ · UPDATED AUGUST 2026 · 536 SECTIONS · 8 CITIES · 2 DEADLINES
If you filed your income tax return this July, you filed it under a law that, technically, no longer exists. That’s not a typo — and understanding why is the key to everything else in this guide.
On 1 April 2026, the Income Tax Act, 2025 replaced the Income Tax Act, 1961 — the law that had governed Indian taxation for 64 years. But if you filed ITR-1 or ITR-2 for FY 2025-26 before the July 31 deadline, you filed it entirely under the old Act. The new one didn’t touch your return at all.
That single distinction — which law applies to which return — is where almost every explainer on this topic, and a fair number of tax professionals in casual conversation, gets sloppy. This guide won’t. Below is exactly what changes, exactly what doesn’t, and exactly what to do about it depending on who you are.

§ § 01 · THE BACKSTORY
Why India Replaced a 64-Year-Old Tax Law
The problem with the 1961 Act
The Income Tax Act, 1961 wasn’t designed for the economy it ended up governing. Over six decades, it was amended so many times that it grew into a genuinely difficult document to navigate — more than 700 sections, layered with sub-clauses, explanations, and cross-references added piecemeal across governments and budgets. A parliamentary committee reviewing the replacement bill noted that the old Act had become cluttered even for experienced tax professionals, and that incremental amendment was no longer a realistic fix. Litigation around interpretation had been climbing for years, partly because the language itself was ambiguous in places.
What the 2025 Act set out to fix
The new Act had four stated goals: simplify the language and structure, reduce the disputes that come from unclear drafting, make compliance easier for ordinary taxpayers rather than just tax professionals, and modernise the administrative machinery — including how digital records and digital assets are treated. The most visible result: the Act has been cut from more than 700 sections and roughly 823 pages down to 536 sections and about 622 pages. That’s a real, structural simplification, not a cosmetic one.
What it is not is a tax cut, a new set of rates, or a reason to expect a different number on your tax bill. That distinction matters more than almost anything else in this article.
§ § 02 · THE CORE CONFUSION
The One Confusion That’s Tripping Up Even CAs
AY 2026-27 and Tax Year 2026-27 are not the same thing
Here’s the part that causes almost all of the confusion around this topic.
Assessment Year (AY) 2026-27 refers to the return you file in 2026 for income you earned in the previous financial year — FY 2025-26 (1 April 2025 to 31 March 2026). That return, its forms, its deductions, and its rules are all governed by the Income-tax Act, 1961, because the income itself was earned before the new Act took effect.
Tax Year 2026-27, on the other hand, is a new term introduced by the 2025 Act. It refers to income earned from 1 April 2026 onward, and it’s governed by the Income-tax Act, 2025. You’re living through Tax Year 2026-27 right now, in August 2026 — but you won’t actually file a return for it until sometime in 2027.
So when someone says “the new Income Tax Act is already affecting my taxes,” the honest answer is: not for the return you just filed or are about to file. It affects the income you’re earning right now, which you’ll report next year.
Quick reference: which law applies to your return
| If you’re filing for… | Governed by | Deadline |
| FY 2025-26 income (AY 2026-27 return) | Income-tax Act, 1961 | 31 Jul / 31 Aug 2026 |
| FY 2026-27 income (Tax Year 2026-27 return) | Income-tax Act, 2025 | Due in 2027 |
| Any pending case from before 1 Apr 2026 | Income-tax Act, 1961 (unchanged) | As per existing timeline |
§ § 03 · NEW VOCABULARY
What Is a “Tax Year,” and Why Did Assessment Year Disappear?
Under the old system, income earned between April 1 and March 31 was called the Previous Year, and the tax return for that income was filed and assessed in the following Assessment Year. So income earned in FY 2025-26 was assessed in AY 2026-27 — two different labels for two sides of the same 12-month cycle, and a structure that taxpayer guides have had to re-explain year after year because it never stopped confusing people.
The 2025 Act collapses both terms into one: the Tax Year. It’s still the same April-to-March, 12-month period — nothing about when the year starts or ends has changed. What’s changed is that income is now referred to using the same year label in which it was earned, rather than being pushed forward into a differently-numbered assessment year. It’s a naming fix, not a computation change. Your financial year, as an accounting concept, still exists exactly as before — “Tax Year” is simply the term the law now uses for income-tax purposes specifically.
§ § 04 · WHO’S AFFECTED, AND HOW
What Actually Changes: A Practical, Segment-by-Segment Breakdown
Most coverage of this topic explains the law in the abstract. Here’s what it actually means depending on who you are.
| IF YOU’RE SALARIED Your FY 2025-26 return is untouched. From April 2026 onward: HRA rules improve if you’re in Bengaluru, Hyderabad, Pune or Ahmedabad (old regime only), and Form 12BB is replaced by Form 124. Slabs and standard deduction haven’t moved. | FREELANCERS & SMALL BUSINESS Non-audit business/professional taxpayers now get until 31 August to file — a full month later than salaried filers. Expect compliance tracking to get more data-driven, not less, over time. |
| INVESTORS Exchanges must now keep 7-year audit trails. Crypto/VDA definition widened to explicitly include “crypto-asset” — tax rate (30%) and TDS (1%) unchanged, but reporting penalties are tighter. | NRIs Foreign asset disclosure rules are stricter, with heavier penalties for non-disclosure. NRE account interest remains tax-free. Old-regime senior-citizen slabs still don’t apply to NRIs. |
| SENIOR CITIZENS Nothing rolled back. Higher exemption thresholds under the old regime — ₹3L for 60–79, ₹5L for 80+ — continue exactly as before. | DIVIDEND RECIPIENTS Companies must now pay dividends only to India-based accounts and maintain tighter governance records. Retail shareholders will notice very little change day to day. |
§ § 05 · THE OTHER LIST
What Does Not Change
It’s worth being explicit about this, because “everything that changed” tends to crowd out the more useful list of what stayed exactly the same:
- Tax rates and slabs — untouched by this Act, and Budget 2026 introduced no rate changes either.
- New-regime-as-default structure — still the default, with the old regime available as an opt-in.
- Regime-switching rules — salaried individuals without business income can still switch every year; those with business income, only once.
- Filing mechanics for FY 2025-26 — same forms, same portal, same 1961 Act provisions.
- Pending disputes — any case open as of 1 April 2026 continues under the old Act, protected by a specific saving clause.
- The basic architecture of progressive taxation — still slabs, still rising rates. Only the numbering and drafting changed.
§ § 06 · THE REAL COMPARISON
New Tax Regime vs. Old Tax Regime for Tax Year 2026-27
Because the underlying regime structure hasn’t changed, this comparison still applies — the numbering just moves from the familiar Section 115BAC (1961 Act) to its renumbered equivalent under the 2025 Act.
| Slab | New Regime | Old Regime |
| ₹0 – 2.5L | — | Nil |
| ₹0 – 4L | Nil | — |
| ₹2.5L – 5L | — | 5% |
| ₹4L – 8L | 5% | — |
| ₹5L – 8L | — | 20% |
| ₹8L – 10L | 10% | 20% |
| ₹10L – 12L | 10% | 30% |
| ₹12L – 16L | 15% | 30% |
| ₹16L – 20L | 20% | 30% |
| ₹20L – 24L | 25% | 30% |
| Above ₹24L | 30% | 30% |
| Standard deduction | ₹75,000 for salaried/pensioners | Also available |
| Rebate | Up to ₹60,000 — zero tax up to ₹12L | Lower threshold |
| HRA exemption | Not available | Available — now 50% in 8 cities |
| 80C, home loan interest, LTA | Not available | Available |
| HOW TO ACTUALLY CHOOSE The new regime tends to win if you have few deductions to claim. The old regime tends to win if you have substantial 80C investments, a home loan, and — especially now — if you pay meaningful rent in one of the eight HRA-eligible cities. Run both numbers before assuming; don’t default to whichever one is “default” by law. |
§ § 07 · THE CHANGE THAT’S FLYING UNDER THE RADAR
The HRA Change Almost Nobody’s Talking About
For decades, only four cities in India qualified for the higher, 50%-of-salary HRA exemption rate. Every other city — including major tech and business hubs where rents had climbed just as sharply — was capped at 40%, regardless of how much rent people were actually paying.
From Tax Year 2026-27 (income earned 1 April 2026 onward), four more cities join the list:
| Delhi | Mumbai | Kolkata | Chennai |
| Bengaluru NEW | Hyderabad NEW | Pune NEW | Ahmedabad NEW |
Three caveats matter:
- It’s old-regime-only. If you’ve opted into the new tax regime, HRA exemption doesn’t apply to you at all, city list or not.
- It’s not retroactive. For the FY 2025-26 return you filed by July or August 2026, the old four-city rule still applies — these four new cities are still treated at 40% for that specific return.
- A new disclosure requirement comes with it. Form 12BB is being replaced by Form 124, requiring disclosure of your relationship with your landlord if annual rent exceeds ₹1 lakh and the landlord is a family member. This is clearly aimed at closing a long-standing avoidance pattern — so if your landlord genuinely is a relative, be ready to disclose it honestly rather than skip the field.
§ § 08 · DON’T MISS THIS
ITR Deadlines for AY 2026-27
This is where the confusion has been most visible in the last few weeks — and it’s a simple fix once it’s laid out clearly:
| 31 Jul Salaried employees, pensioners, and anyone without business/professional income (ITR-1, ITR-2) | 31 Aug Business or professional income, no audit required (ITR-3, ITR-4/Sugam) |
A later date still applies to audit cases — commonly around October 31, though you should confirm the exact date for your category rather than assume. Miss your deadline and you can still file a belated return, but at a cost: interest on unpaid tax, a late-filing penalty, delayed refunds, and restrictions on carrying forward certain losses.
§ § 09 · LEARN FROM OTHERS
7 Mistakes Taxpayers Are Making Right Now
- Assuming the new Act already changed this year’s return. It didn’t. FY 2025-26 income is still governed entirely by the 1961 Act.
- Mixing up “Tax Year 2026-27” with “AY 2026-27.” They sound almost identical and refer to completely different laws and timelines.
- Assuming the new HRA cities apply to the return being filed right now. They don’t — they apply to income earned from April 2026 onward.
- Guessing at the filing deadline instead of confirming it. Freelancers assuming July 31 applies to them, and business owners assuming they automatically get the later date, are both common this season.
- Skipping the landlord-relationship disclosure on Form 124 when the landlord is genuinely a family member — this field exists specifically to catch that pattern.
- Believing both regimes let you claim HRA. Only the old regime does.
- Assuming small crypto transactions won’t be noticed. Between TDS thresholds and the newly tightened VDA penalty structure, this is the wrong year to assume that.
§ § 10 · DO THIS NEXT
Your Action Checklist for Tax Year 2026-27
- Confirm which law applies to the return you’re currently filing (FY 2025-26 income = 1961 Act, full stop).
- Check your specific ITR deadline based on your income type, rather than assuming the most-publicised date applies to you.
- If you live in Bengaluru, Hyderabad, Pune or Ahmedabad and pay rent, run the numbers on old vs. new regime once the new HRA rate applies to your Tax Year 2026-27 income.
- If your landlord is a family member, prepare to disclose that relationship honestly once Form 124 becomes applicable to you.
- If you hold or trade crypto/VDAs, keep clean, transaction-level records.
- If you’re an NRI, review your foreign asset disclosures now, rather than waiting for a notice to prompt it.
- Learn the term “Tax Year” now, so payslips and TDS certificates that start using it don’t catch you off guard.
- If you have a pending assessment or notice from before April 2026, know that it continues unaffected under the old Act.
§ § 11 · SETTING THE RECORD STRAIGHT
Myths About the Income Tax Act 2025, Busted
| MYTH My tax slab changed this year because of the new Act. |
| FACT Budget 2026 introduced no slab changes. The Act itself is structural, not rate-based. You’d owe the same amount under the old law. |
| MYTH Tax Year has replaced Financial Year. |
| FACT The financial year (April–March) still exists exactly as before. “Tax Year” is simply the new label for income-tax purposes specifically. |
| MYTH I don’t need to think about this until I file next year. |
| FACT True for filing — false for planning. You’re already living through Tax Year 2026-27, so decisions you make now are already governed by the new provisions. |
| MYTH Everyone pays less tax now. |
| FACT No across-the-board reduction was introduced. Some taxpayers benefit from specific provisions — that’s not the same thing. |
| MYTH The old tax regime is being phased out. |
| FACT Not supported by anything in the current Act. It remains available as an explicit opt-in, with no announced removal timeline. |
§ § 12 · QUESTIONS, ANSWERED
Frequently Asked Questions
Q1. Does the Income Tax Act 2025 apply to the return I’m filing right now?
No. If you’re filing for FY 2025-26 income (AY 2026-27), that return is governed entirely by the Income-tax Act, 1961. The 2025 Act applies to income earned from 1 April 2026 onward, which you’ll report in a return filed next year.
Q2. What is a “Tax Year” under the new Act?
A single, unified 12-month period (1 April to 31 March) that replaces the old dual concept of Previous Year and Assessment Year. Income is now referred to using the year it was earned in, rather than a separately numbered assessment year.
Q3. Why was the Income Tax Act, 1961 replaced?
After 64 years and hundreds of amendments, the old Act had become difficult to navigate and was generating rising interpretation-related litigation. The new Act simplifies language and structure without changing tax rates.
Q4. Did my tax slab change under the new Act?
No. Tax slabs are set by the annual Budget, not by this Act. Budget 2026 made no changes to slabs, the standard deduction, or the rebate under either regime.
Q5. How many sections does the new Income Tax Act have?
536 sections, down from more than 700 under the 1961 Act — roughly a 50% reduction. The Act itself runs to about 622 pages, down from roughly 823.
Q6. Is the old tax regime still available?
Yes. The new tax regime remains the default, but the old regime continues to be available as an explicit opt-in choice when filing your return, or by informing your employer if salaried.
Q7. Can I switch between the old and new regime every year?
If you’re salaried without business or professional income, yes. If you have business or professional income, you can generally switch only once.
Q8. What happens to HRA exemption under the new Act?
The core rules haven’t changed structurally, but from Tax Year 2026-27, four more cities — Bengaluru, Hyderabad, Pune, and Ahmedabad — now qualify for the higher 50% exemption rate. This benefit is only available under the old tax regime.
Q9. Does the new HRA city list apply to the return I’m filing this year?
No. For your FY 2025-26 return, the old four-city rule still applies. The expanded eight-city list applies to income earned from April 2026 onward.
Q10. What is Form 124, and why does it matter?
It replaces Form 12BB for investment and HRA declarations to employers, adding a requirement to disclose your relationship with your landlord when annual rent exceeds ₹1 lakh and the landlord is a family member.
Q11. What’s the ITR filing deadline for AY 2026-27?
31 July 2026 for salaried individuals and pensioners. 31 August 2026 for business/professional income without a tax audit requirement. Audit cases have a later deadline still — confirm your specific category.
Q12. What happens if I miss my ITR deadline?
You can still file a belated return, but you’ll face a late-filing penalty, interest on unpaid tax, delayed refunds, and restrictions on carrying forward certain losses to future years.
Q13. How does the new Act affect NRIs?
Foreign asset disclosure requirements are stricter, with heavier penalties for non-disclosure of foreign bank accounts, property, or shares. NRE account interest remains tax-free.
Q14. Does the new Act change crypto/VDA taxation rates?
No. The flat 30% tax on VDA transfer profits and the 1% TDS remain unchanged. What’s changed is the legal definition (explicitly widened to include “crypto-asset”) and a tighter penalty structure for reporting failures.
Q15. What happens to pending tax cases filed before April 2026?
They continue to be governed by the old 1961 Act. The new Act includes a specific saving clause to ensure it doesn’t disrupt proceedings already underway.
Q16. Do senior citizens lose any benefits under the new Act?
No. The higher exemption thresholds for resident senior citizens (60+) and super senior citizens (80+) under the old regime continue unchanged.
Q17. Is the Income Tax Act 2025 a tax cut?
No. It’s a structural rewrite aimed at simplifying language, reducing disputes, and modernising compliance — not a change to how much tax anyone owes.
Q18. Do I need to file differently because of the new Act this year?
No. Your filing process, forms, and applicable law for FY 2025-26 income are unchanged. Differences begin with income earned from April 2026 onward.
Q19. What should I actually do right now because of this change?
Confirm your correct filing deadline, understand that the new HRA and Tax Year provisions apply to income you’re earning now (not the return you’re filing now), and start keeping cleaner records if you invest in crypto or have foreign assets.
Q20. Where can I check the official text of the new Act?
The Income Tax Department’s official portal (incometaxindia.gov.in) publishes the Income-tax Act, 2025 and the Income-tax Rules, 2026, along with CBDT circulars — the most reliable source for anything beyond general understanding.

§ § 14 · THE TAKEAWAY
Conclusion
The honest summary of the Income Tax Act 2025 is this: it’s a genuine, overdue simplification of how India’s tax law is written and administered — not a change to how much tax you pay. The confusion around it comes almost entirely from timing: the Act is “in effect,” but it governs income you’re earning now, not the return you just filed or are about to file. Once that distinction is clear, most of the rest — the Tax Year terminology, the expanded HRA city list, the tighter compliance around crypto and foreign assets — is straightforward to apply to your specific situation.
If there’s one thing worth doing after reading this: don’t just note that the law changed. Go back to the action checklist above and actually check which of those eight items apply to you — because for most taxpayers, at least two or three will.
