New Income Tax Act 2025: What Common People Need to Know from April 1, 2026

Your CA called to say “the new Income Tax Act kicks in from April.” Your colleague forwarded three WhatsApp forwards claiming “80C is gone” and “senior citizens will pay more.” Your neighbour said something about “previous year being abolished.” And you sat there thinking — do I need to do something different when I file my return this year or not?

Short answer: for most salaried taxpayers, your actual tax liability stays the same. But the New Income Tax Act 2025 does change some terminology you’ll encounter on the e-filing portal, and there are a few things worth knowing before you file.

What This Act Actually Is — and What It Isn’t

The Income Tax Act 2025 (formally the Income-Tax (No. 2) Bill, 2025, passed by both Houses of Parliament in August 2025) replaces the Income Tax Act 1961. Not amended — replaced. It takes effect on April 1, 2026.

But here’s what most of those WhatsApp forwards got wrong: this is a simplification exercise, not a tax hike. The government explicitly described it as “revenue-neutral.” Tax rates, slabs, deductions, and rebates for individuals are unchanged. What changed is how the law is written and structured — 536 sections across 23 chapters, replacing 64 years of amendments layered on top of amendments.

Think of it as India’s tax code getting a thorough rewrite in plain English (or plain Hindi). The rules inside are largely the same; the filing experience is expected to become cleaner over time.

The “Tax Year” Change — The One That Will Confuse Everyone Initially

Under the 1961 Act, Indian taxpayers had to deal with two terms: Previous Year (the year you earn income — April 2025 to March 2026) and Assessment Year (the year you file and pay tax on that income — April 2026 to March 2027). This was genuinely confusing. People filed ITR for AY 2026-27 on income earned in FY 2025-26, and explaining that to anyone outside a CA firm required a small diagram.

Under the Income Tax Act 2025, this duality is replaced by a single concept: Tax Year. The Tax Year runs from April 1 to March 31 — same as the financial year. Income earned in Tax Year 2026-27 (April 2026 to March 2027) will be assessed and taxed in that same Tax Year.

The immediate practical effect: when the e-filing portal (https://www.incometax.gov.in) updates its labels to reflect the new Act, you may see “Tax Year 2026-27” instead of “Assessment Year 2026-27” on dropdown menus and forms. The underlying filing process remains the same.

I’ve seen people panic when portal labels change without any corresponding change in what they actually need to do. This is one of those moments. The ITR form for your income from April 2026 onwards will say Tax Year 2026-27 — that is the year you earned it, not a year ahead.

Tax Rates and Slabs: What Actually Applies from April 1, 2026

The Finance Act 2025 (Budget 2025, presented in February 2025) overhauled the tax slabs under the new regime. Those rates continue unchanged for Tax Year 2026-27 as well — Budget 2026 made no changes to individual tax slabs (as confirmed in the Finance Bill 2026).

New Tax Regime slabs — Tax Year 2026-27 (default for all individuals):

Plus 4% Health & Education Cess on computed tax in both regimes. Surcharge applies for incomes above ₹50 lakh; capped at 25% under the new regime.

Old Tax Regime rates remain unchanged: 5% (₹2.5–5 lakh), 20% (₹5–10 lakh), 30% (above ₹10 lakh) for individuals below 60. Senior citizens (60–80 years) continue to get a basic exemption of ₹3 lakh; super senior citizens (above 80) get ₹5 lakh.

The new regime is the default. Unless you actively select the old regime when filing your ITR, the system applies the new regime rates.

Section 87A Rebate — The ₹12 Lakh Zero-Tax Rule Explained Clearly

This is the single most misunderstood number in Indian personal finance right now (naya income tax kanoon mein zero tax kitne tak).

Under the new regime, resident individuals with taxable income up to ₹12 lakh get a rebate under Section 87A of up to ₹60,000 — wiping out the entire tax liability. Combined with the standard deduction of ₹75,000 available to salaried individuals and pensioners, salaried taxpayers earning up to ₹12.75 lakh effectively pay zero income tax.

Two important caveats that most explanations skip:

First: The ₹12 lakh limit applies to total taxable income, not gross salary. If you have short-term capital gains (taxed at 20% under Section 111A) or long-term capital gains (taxed at 12.5% under Section 112A), those are taxed at their special rates regardless of the 87A rebate. The rebate does not apply to special-rate income.

Second: This benefit applies only to resident individuals — not NRIs, not HUFs, not partnership firms or companies.

Under the old regime, Section 87A remains at ₹12,500 for income up to ₹5 lakh. Unchanged.

What Changes on the e-Filing Portal from April 2026

For ITRs filed from April 2026 onwards (for income earned in Tax Year 2026-27), the incometax.gov.in portal will begin reflecting the new Act’s terminology. Specifically:

• “Assessment Year” dropdowns may be relabelled or supplemented with “Tax Year” references
• ITR forms will be redesigned over time (the government stated simplified forms will be notified “giving adequate time to taxpayers” — as per the PIB press release of Budget 2026)
• Some section references in the forms will change: what was “Section 80C” may be renumbered under the new Act. However, the deduction itself remains available under the old regime by whatever new section number applies

The actual filing process on incometax.gov.in does not change for Tax Year 2026-27. You log in the same way, select your ITR form, fill in income details, claim deductions, and file. Until the new forms are notified and the portal updated, the current process continues.

Do not wait for a new portal launch to file. The ITR filing deadline for most individual taxpayers (non-audit cases) is July 31 of each year, as per Section 139(1) of the Income Tax Act (the equivalent provision continues under the 2025 Act). Missing this date attracts a late fee of ₹5,000 under the equivalent of Section 234F, and interest at 1% per month on unpaid tax under Section 234A (2026 Act).

Who Needs to Actually Do Something Different Right Now

Most salaried individuals with straightforward income — salary, FD interest, maybe some mutual fund gains — do not need to take any new action because of the Act change alone. The filing process on the portal is the same.

You do need to pay attention if:

• You were claiming deductions under the old regime (80C, 80D, HRA, home loan interest under Section 24b) — these continue under the new Act’s equivalent provisions under the old regime. But you must actively opt for the old regime at ITR filing. It is no longer the default.
• You have capital gains from equity mutual funds or stocks — the 87A rebate does not apply to LTCG/STCG at special rates, so even if your total income is below ₹12 lakh, those gains are taxed at 12.5% / 20% respectively.
• You run a business or are a professional — switching back to the old regime requires Form 10IEA and has restrictions.

Vikram from Pune, a salaried software engineer earning ₹14 lakh annually, assumed the “₹12 lakh zero tax” rule applied to him entirely. His gross salary was ₹14 lakh, he had ₹2 lakh in LTCG from equity mutual funds, and his net taxable income after standard deduction was ₹13.25 lakh. He owed tax — the LTCG portion was taxed at 12.5% (Section 112A), and the 87A rebate didn’t apply there. A quick run through the tax calculator at https://www.incometax.gov.in (under the “Tax Calculator” option in the left menu after login) would have shown him this before he assumed zero liability.

What Nobody Tells You: Section Numbers Will Change, But Deductions Won’t Disappear

The biggest fear circulating on social media — “80C is gone under the new Act” — is technically true in one narrow sense and completely misleading in every practical sense.

The 1961 Act’s section numbering (80C, 80D, 80CCD, and so on) is reorganised under the 2025 Act. The deduction for life insurance, PPF, ELSS, tuition fees, etc. — what we all know as “80C” — exists in the new Act under a different section number. The deduction limit of ₹1.5 lakh under the old regime is unchanged. The rule hasn’t gone; only the address in the statute has changed.

For practical purposes: the ITR form will have the correct section references pre-loaded. You don’t need to memorise new section numbers. What you need to know is whether you’re filing under the old regime (which allows these deductions) or the new regime (which doesn’t). That choice hasn’t changed.

Savita from Bhopal, a retired government employee, called her bank worried that her PPF account deduction claim would be rejected because “80C is abolished.” Her CA spent 10 minutes reassuring her that the deduction continues — PPF remains tax-exempt on contribution, interest, and maturity under the equivalent provision of the 2025 Act. The provision was moved, not removed.

Common Mistakes to Avoid This Filing Season

❌ Assuming “Tax Year 2026-27” on the portal means income earned from April 2025 to March 2026 ✅ Under the new Act, Tax Year 2026-27 refers to income earned April 2026 to March 2027. For income earned April 2025 to March 2026, you still file under the old framework — the relevant ITR is for AY 2026-27 under the 1961 Act terminology.

❌ Assuming the ₹12 lakh zero-tax benefit applies to all income types ✅ Special-rate income (LTCG under Section 112A at 12.5%, STCG under Section 111A at 20%) is taxed even if your total income is below ₹12 lakh. Always run the tax calculator before concluding your liability is zero.

❌ Not switching back to old regime when it’s more beneficial, because switching “seems complicated” ✅ For non-business salaried individuals, you can switch between old and new regime every year, directly in your ITR form, without any separate form. The system defaults to the new regime; selecting old regime takes one click. Run both calculations before choosing.

❌ Filing your ITR on your phone using a third-party app that hasn’t updated for the new Act’s changes ✅ Use the official portal at https://www.incometax.gov.in or the official AIS/ITR mobile app by Income Tax Department. Third-party apps may lag in reflecting form changes. The mobile version of the official portal works adequately on Chrome; if you face slow loading, try filing on a desktop or laptop.

❌ Missing the July 31 deadline and paying ₹5,000 in late fees unnecessarily ✅ Set a reminder for mid-July. Even if your Form 16 comes late (employers are required to issue it by June 15 as per CBDT rules), you can file with salary slips and AIS data from the portal. Don’t wait for Form 16 to start the process.

❌ Ignoring the Annual Information Statement (AIS) on the portal ✅ Before filing, always download your AIS from incometax.gov.in → “AIS” under the e-File menu. It shows all income sources the department has on record — interest, dividends, capital gains, property transactions. Missing an entry reported in AIS almost always leads to a notice.

FAQ

New Income Tax Act 2025 kab se lagu hoga?

The Income Tax Act 2025 comes into effect on April 1, 2026. Income earned from Tax Year 2026-27 onwards (i.e., from April 1, 2026) is governed by the new Act. Returns for income earned before March 31, 2026 are still filed under the 1961 Act framework.

Does the new Act increase my tax compared to the old 1961 Act?

No. The Income Tax Act 2025 is explicitly revenue-neutral — tax rates, slabs, and deductions are unchanged. The Act simplifies legal language and restructures sections. Your tax liability for the same income is identical under both Acts.

What is “Tax Year” under the new Income Tax Act 2025?

Tax Year replaces the earlier “Previous Year” and “Assessment Year” dual concept. Under the new Act, Tax Year 2026-27 means both the period you earn income (April 2026–March 2027) and the year it is assessed. One term instead of two.

Is income up to ₹12 lakh still tax-free in Tax Year 2026-27?

Yes, under the new tax regime. Resident individuals with taxable income up to ₹12 lakh get a Section 87A rebate of up to ₹60,000 — reducing their tax to zero. Salaried taxpayers additionally get ₹75,000 standard deduction, making income up to ₹12.75 lakh effectively tax-free. Capital gains at special rates are excluded from this rebate.

Does 80C deduction still exist after April 2026?

The deduction itself continues under the old tax regime — same amount (₹1.5 lakh), same eligible instruments (PPF, ELSS, life insurance, tuition fees). The section number changes under the 2025 Act’s new structure, but the ITR form will reflect the correct new reference automatically.

Where do I file my income tax return from April 2026?

At https://www.incometax.gov.in — same portal. The login, PAN-based registration, and filing process remain unchanged. Forms will be updated to reflect new Act terminology over time; the portal will display the correct form for your applicable Tax Year.

What is the ITR filing deadline for Tax Year 2026-27?

For most salaried individuals and non-audit cases, the due date is July 31, 2027 (for income earned April 2026 to March 2027). Missing this attracts a late fee of ₹5,000 and interest at 1% per month on unpaid tax, as per equivalent provisions of the 2025 Act.

Kya senior citizens ko zyada tax dena hoga ab?

No. Senior citizens (60–80 years) retain their basic exemption limit of ₹3 lakh under the old regime. Super senior citizens (above 80) retain ₹5 lakh. Under the new regime, the ₹4 lakh basic exemption limit applies uniformly to all ages, but the Section 87A rebate of ₹60,000 is available to senior citizens under the new regime as well for income up to ₹12 lakh.

The Act is new. The confusion is real. But your actual tax obligation for Tax Year 2026-27 depends on the same slabs and the same regime choice you’ve been dealing with for the last two years — the 2025 Act just cleaned up the legal wording around it.

Run your numbers on the official calculator at incometax.gov.in before the fiscal year ends. File by July 31. And next time a WhatsApp forward tells you “80C is gone,” you’ll know exactly what to say.
