NEW INCOME TAX RULES 2026 What Changes from April 1?
📋 QUICK SUMMARY — 7 Things That Change for You from April 1, 2026 April 1, 2026 marks the single biggest overhaul of India’s direct tax architecture since Independence. Three headline changes land simultaneously: (1) The Income Tax Act 2025 replaces the 64-year-old Income Tax Act 1961 — same tax rates, but a radically simpler law. (2) The new tax regime (Section 115BAC) slabs introduced in Budget 2025 fully take effect for FY 2026-27, keeping income up to ₹12 lakh effectively tax-free. (3) A wave of TDS rationalisation, revised ITR due dates, an expanded 48-month window to file updated returns, and new rules on MAT, TCS, and education/hostel allowances all come into force together. This guide, written from 15 years of banking and financial services experience and sourced from official Finance Ministry documents, breaks down every change that matters to you
| ₹0 Tax on income up to ₹12L New regime + Sec 87A rebate | 536 sections in IT Act 2025 vs 819 in IT Act 1961 | 48 months to file updated ITR extended from 24 months | ₹12.75L effective tax-free (salary) after ₹75,000 std. deduction |
Why April 1, 2026 Is Different from Every Other April 1
Every April 1 in India ushers in a new financial year with its assortment of small rule tweaks. But April 1, 2026 is categorically different. On this date, India’s Income Tax Act 1961 — a law drafted in the Nehru era, patched by 65 consecutive Finance Acts, swollen to 819 sections across 47 chapters — formally ceases to govern direct tax in India. It is replaced by the Income Tax Act 2025: a clean, consolidated, 536-section statute built for a digital economy, faceless assessments, and ordinary citizens who should be able to understand their own tax obligations without hiring a lawyer to decode the law.
But the new Act is not the only thing changing. The tax slab structure overhauled in Budget 2025 (presented in February 2025) fully takes effect for FY 2026-27. The enhanced Section 87A rebate that makes income up to ₹12 lakh effectively tax-free continues unchanged. TDS threshold rationalisations already in effect since April 2025 are now further codified under the new Act. A cascade of updates to TCS rates, ITR due dates, updated return filing windows, education and hostel allowances, and MAT (Minimum Alternate Tax) all activate simultaneously.
For the average taxpayer, this is both an opportunity and a deadline. An opportunity to pay significantly less tax under the new regime if you haven’t switched yet — and a deadline to ensure you have your tax planning aligned with a new legal framework before the financial year begins.
📌 Key Clarification: New Act, Same Tax Rates The Income Tax Act 2025 is explicitly a ‘revenue-neutral’ reform. It does not introduce new taxes, raise existing rates, or eliminate deductions. Every slab, rate, deduction, and exemption that existed on March 31, 2026 carries forward into the new Act — just under cleaner, simpler language. The goal is ease of compliance, not new taxation.
The 7 Key Changes from April 1, 2026
📜 Change #1: Income Tax Act 2025 Replaces the 1961 Act 📌 What changed: The Income Tax Act 2025 comes into force on April 1, 2026, replacing the Income Tax Act 1961 in its entirety. The new Act reduces sections from 819 to 536, chapters from 47 to 23, and schedules to 16. Outdated provisions, redundant sections (like Section 10A that had been redundant since 2012 but stayed in the Act for over a decade), and convoluted language have been eliminated. All TDS provisions — previously spread across Sections 192 to 194T (over 60 separate sections) — are now consolidated into just three sections: 392 (salary TDS), 393 (non-salary TDS), and 394 (TCS).
💼 Impact on you: Your day-to-day tax obligation does not change in amount. But compliance becomes significantly simpler. New ITR forms redesigned under the new Act will be easier to understand. The faceless assessment framework is now legislatively embedded, reducing arbitrary interactions. For businesses and CAs, the single-statute approach eliminates the need to cross-reference dozens of circulars and amendments.
✅ Action: Familiarise yourself with the new section numbering. If your CA or employer refers to ‘Section 87A’ under the new Act, the provision number may differ from the 1961 Act reference — but the benefit is identical. Download the Income Tax Act 2025 from the official CBDT website (incometaxindia.gov.in) for reference.
💰 Change #2: New Tax Regime Slabs — Continued for FY 2026-27 📌 What changed: Finance Minister Nirmala Sitharaman confirmed in Budget 2026-27 that the slab structure introduced in Budget 2025 continues unchanged for FY 2026-27. The new regime basic exemption limit remains ₹4 lakh. A new 25% slab for income between ₹20 lakh and ₹24 lakh — introduced in Budget 2025 — continues. The 30% highest slab now only applies above ₹24 lakh (previously above ₹15 lakh). The new regime under Section 115BAC remains the default regime.
💼 Impact on you: Individuals previously paying 30% on income above ₹15 lakh now pay 25% on the ₹20–24 lakh bracket and 30% only above ₹24 lakh. A person earning ₹15 lakh benefits from a net tax reduction of approximately ₹35,000 compared to the slab structure of two years ago. For the ₹20–₹24 lakh income group, the new 25% slab creates material tax savings versus both the old regime and the pre-2025 new regime.
✅ Action: Do not assume your FY 2025-26 tax calculation automatically applies to FY 2026-27. Recompute using the FY 2026-27 slabs. If your income has grown into a new bracket, verify the applicable rate. Use the official IT Department calculator at incometax.gov.in.
New Regime vs Old Regime Tax Slabs — FY 2026-27 (Tax Year 2026-27)
The table below shows applicable slab rates for both regimes for Tax Year 2026-27 (i.e., income earned from April 1, 2026 to March 31, 2027).
| Taxable Income (₹) | Tax Rate — New Regime FY 2026-27 | Tax Rate — Old Regime FY 2026-27 |
| Up to ₹2,50,000 | Nil | Nil |
| ₹2,50,001 – ₹4,00,000 | Nil | 5% |
| ₹4,00,001 – ₹5,00,000 | 5% | 5% |
| ₹5,00,001 – ₹8,00,000 | 5% | 20% |
| ₹8,00,001 – ₹10,00,000 | 10% | 20% |
| ₹10,00,001 – ₹12,00,000 | 10% | 30% |
| ₹12,00,001 – ₹15,00,000 | 15% | 30% |
| ₹15,00,001 – ₹16,00,000 | 15% | 30% |
| ₹16,00,001 – ₹20,00,000 | 20% | 30% |
| ₹20,00,001 – ₹24,00,000 | 25% | 30% |
| Above ₹24,00,000 | 30% | 30% |
Note: Under new regime, income up to ₹12 lakh is effectively tax-free due to Sec 87A rebate (₹60,000). Salaried individuals with income up to ₹12.75 lakh pay zero tax after ₹75,000 standard deduction. Add 4% Health & Education Cess on computed tax. Source: Finance Act 2025, Finance Bill 2026, CBDT.
🎁 Change #3: Section 87A Rebate — ₹60,000 / Zero Tax Up to ₹12 Lakh Continues 📌 What changed: The Section 87A rebate of ₹60,000 under the new tax regime, which made income up to ₹12 lakh effectively tax-free for FY 2025-26, is retained unchanged for FY 2026-27. Salaried individuals additionally benefit from the ₹75,000 standard deduction, bringing the effective zero-tax threshold to ₹12.75 lakh of gross salary. Under the old regime, the Section 87A rebate remains ₹12,500, applicable for taxable income up to ₹5 lakh.
💼 Impact on you: This is one of the most significant personal tax benefits in recent Indian tax history. A salaried professional earning ₹12.75 lakh gross salary in FY 2026-27 under the new regime pays zero income tax — provided they have no special-rate income like capital gains under Section 111A or 112A, which are excluded from the rebate calculation. For a household previously paying ₹1.5–₹1.7 lakh in tax on a ₹12 lakh income, this is equivalent to a substantial take-home salary increase.
✅ Action: Calculate your taxable income carefully before assuming zero-tax status. The ₹12 lakh threshold applies to total taxable income after the standard deduction — not gross salary. Capital gains income is NOT covered by the rebate even if other income is below ₹12 lakh. If you have STCG or LTCG, compute tax on those amounts separately at applicable special rates.
Indicative Tax Savings: New Regime vs Old Regime FY 2026-27
The table below shows estimated tax liability for selected income levels under both regimes, assuming standard salaried profile (no special-rate income). Figures include 4% cess.
| Annual Salary (₹) | Tax (Old Regime) | Tax (New Regime) | Saving with New Regime |
| ₹7,00,000 | ₹54,600 | ₹0 | ₹54,600 |
| ₹10,00,000 | ₹1,17,000 | ₹54,600 | ₹62,400 |
| ₹12,75,000 | ₹1,73,550 | ₹0 | ₹1,73,550 (salaried) |
| ₹15,00,000 | ₹2,10,600 | ₹97,500 | ₹1,13,100 |
| ₹20,00,000 | ₹3,58,800 | ₹1,79,400 | ₹1,79,400 |
Note: Figures are indicative for a salaried individual under 60 with no other income. Old regime assumes standard deduction of ₹50,000 and no additional 80C/80D deductions for comparability. Actual tax depends on individual deductions and surcharge applicability. Source: DailyFinancial.in calculations based on official slab rates.
🗓️ Change #4: New Terminology: ‘Tax Year’ Replaces ‘Financial Year’ and ‘Assessment Year’ 📌 What changed: One of the most practically significant structural changes in the Income Tax Act 2025 is the abolition of the dual Financial Year (FY) / Assessment Year (AY) framework. The new Act introduces a single concept: ‘Tax Year.’ Under this system, the Tax Year is the year in which income is earned — identical to what was previously called the Financial Year. There is no separate ‘Assessment Year’ reference for the same period. Tax Year 2026-27 refers to income earned from April 1, 2026 to March 31, 2027.
💼 Impact on you: This change eliminates one of the most common sources of confusion for individual taxpayers — the perpetual question of ‘what is the Assessment Year for FY 2025-26?’ The answer to the equivalent question from April 2026 onwards is simply: it is Tax Year 2026-27 for income earned in Tax Year 2026-27. Notice on Form 16, ITR forms, and all CBDT communications will use the new terminology from FY 2026-27 onwards.
✅ Action: When reading ITR forms, notices, and CBDT communications from April 2026, note that ‘Tax Year 2026-27’ = what was previously FY 2026-27 (AY 2027-28). Ensure your CA and payroll team are aligned on the new terminology to avoid misfiling.
📊 Change #5: TDS Threshold Rationalisation — Fewer Surprise Deductions 📌 What changed: The TDS (Tax Deducted at Source) threshold rationalisations announced in Budget 2025 and operative since April 1, 2025 are now embedded in the Income Tax Act 2025 effective from FY 2026-27. Key changes include: interest on bank FDs for senior citizens now attracts TDS only above ₹1,00,000 (doubled from ₹50,000); the professional fees TDS threshold under what was Section 194J rises to ₹50,000 from ₹30,000; rent TDS on plant and machinery moves from ₹2,40,000 to ₹6,00,000 annually. Additionally, the new Act consolidates all 60+ TDS sections into three clean sections with structured rate tables.
💼 Impact on you: For senior citizens earning FD interest, this means significantly fewer TDS deductions and smaller refund claims. For small service providers, the higher professional fee threshold reduces the administrative burden of tracking TDS certificates. For property owners letting plant/machinery, the higher rent threshold reduces compliance friction for smaller rental arrangements.
✅ Action: Verify that banks and payers have updated their TDS calculation systems to the revised thresholds. If you were receiving TDS deductions at old (lower) thresholds, check whether excess TDS has already been deducted in the current FY and file for a refund as appropriate via your ITR.
Selected TDS Threshold Changes Effective April 2025 / April 2026
The following table summarises key TDS threshold changes. Changes operative since April 2025 are now legislatively codified under the IT Act 2025 from April 2026.
| TDS Section / Nature | Old Threshold | New Threshold (From Apr 2025) | Rate |
| Sec 193 — Interest on securities | ₹5,000 | ₹10,000 | 10% |
| Sec 194 — Dividend | ₹2,500 | ₹5,000 | 10% |
| Sec 194A — Bank interest (others) | ₹40,000 | ₹50,000 | 10% |
| Sec 194A — Sr Citizen bank interest | ₹50,000 | ₹1,00,000 | 10% |
| Sec 194B — Lottery/Game winnings | ₹10,000/txn | ₹10,000/year | 30% |
| Sec 194D — Insurance commission | ₹15,000 | ₹20,000 | 5%/2% |
| Sec 194G — Commission on lotto | ₹15,000 | ₹20,000 | 5% |
| Sec 194H — Brokerage/Commission | ₹15,000 | ₹20,000 | 2% |
| Sec 194I — Rent (plant & machinery) | ₹2,40,000 | ₹6,00,000 | 2% |
| Sec 194J — Prof./Technical fees | ₹30,000 | ₹50,000 | 2%/10% |

🔄 Change #6: TCS Rate Changes + 48-Month Updated Return Window 📌 What changed: Two significant compliance-easing changes take effect from April 2026. First, TCS rate rationalisation: TCS on overseas tour packages under LRS is now a flat 2% (previously 5% and 20% depending on amount), TCS on LRS remittances for education and medical treatment drops from 5% to 2%, and TCS on sale of scrap, alcoholic liquor, and minerals rises to 2% from 1%. Second: the window to file an Updated Return (ITR-U) has been extended from 24 months to 48 months from the end of the relevant tax year — allowing taxpayers to voluntarily correct past returns and pay additional tax for up to four preceding years.
💼 Impact on you: For frequent international travellers and students paying overseas education fees, the lower TCS rate means less money blocked as advance tax — improving cash flow. The 48-month updated return window is particularly valuable for those who missed income disclosures or made computation errors: you can now come forward voluntarily, pay the additional tax with a penalty surcharge, and avoid prosecution risk on a much longer horizon.
✅ Action: If you have sent money abroad for education or tour packages in recent years and had 5–20% TCS deducted, check your Form 26AS to ensure this has been credited against your tax liability. If not, file the updated return to claim credit. For TCS on scrap sales, update your TCS calculation systems for the 2% rate from April 2026.
🏭 Change #7: MAT Made Final Tax + Education/Hostel Allowance Hike 📌 What changed: Two more significant changes complete the April 2026 package. For companies: Minimum Alternate Tax (MAT) becomes a ‘final tax’ from April 1, 2026 — companies will no longer accumulate MAT credit from this date onwards (existing MAT credit accumulated until March 31, 2026 can still be offset at ¼ of new regime tax liability per year). The MAT rate is simultaneously reduced from 15% to 14%. For salaried employees: the Draft Income Tax Rules 2026 propose raising the education allowance exemption from ₹100/month per child to ₹3,000/month per child, and hostel allowance from ₹300/month per child to ₹9,000/month per child — a 30x increase that reflects market reality after decades without revision.
💼 Impact on you: For companies in the new regime, the end of MAT credit accumulation simplifies long-term tax planning and reduces deferred tax accounting complexity. For salaried parents claiming education and hostel allowances under the old tax regime, the proposed increase (subject to final notification of the rules) can meaningfully reduce taxable income — potentially making the old regime more competitive for some taxpayer profiles than previously calculated.
✅ Action: Companies: review your deferred MAT credit position before March 31, 2026 and model the impact of the final-tax status. Individual taxpayers: once the Income Tax Rules 2026 are formally notified, recompute old vs new regime comparison factoring in the higher education/hostel allowances to determine which regime remains optimal.
Old Regime vs New Regime: Who Should Switch?
With the new tax regime firmly established as the default and offering zero tax up to ₹12 lakh, many taxpayers are asking whether they should still stick with the old regime. The answer depends entirely on the magnitude of deductions they can legitimately claim. The breakeven analysis is straightforward:
The new regime is almost certainly better if: you have limited investments under 80C, minimal HRA, no home loan interest deduction, and no large medical insurance premiums. For someone earning ₹15 lakh with standard deductions only, the new regime saves over ₹1 lakh in tax annually compared to the old regime with no deductions.
The old regime may still win if: you are maximising 80C (₹1.5 lakh), paying substantial home loan interest (Section 24B allows up to ₹2 lakh deduction), claiming HRA, and have significant 80D medical insurance premiums. In that scenario, a taxpayer can reduce taxable income by ₹4–5 lakh before comparing to the new regime rates.
The proposed increase in education (₹3,000/month) and hostel (₹9,000/month) allowances under Draft IT Rules 2026 — once notified — could tip the calculation further toward the old regime for parents with children in boarding schools or hostels.
💡 Expert Tip: Always Run Both Calculations Before April 1 Do not rely on your employer’s default assumption about which regime is better for you. Your employer applies the default new regime unless you specifically submit a declaration. If the old regime is more beneficial for your profile — especially if you have a home loan and substantial 80C investments — submit the Form 10IEA declaration before April 1. Once the financial year begins, salaried employees can switch again only when filing their ITR by July 31.
The Bottom Line: What You Must Do Before April 1
The April 1, 2026 transition is the most significant date in India’s income tax calendar since the introduction of the new tax regime in 2020. For individuals, the most pressing task is the regime choice decision — run both old and new regime calculations for your expected FY 2026-27 income and deduction profile before April 1, and communicate your choice to your employer if you wish to opt out of the default new regime.
For businesses, the end of MAT credit accumulation and the new Act’s structural changes require a review of deferred tax positions and compliance systems. For everyone, the new ‘Tax Year’ terminology and the consolidated section numbering in the Income Tax Act 2025 mean that all reference materials, online filing guides, and CA advisories will update their language — be prepared for temporary navigation confusion as the ecosystem catches up.
The overarching message from the government is clear: compliance should be easier, transparency should be higher, and the default path — the new tax regime with zero tax up to ₹12 lakh — should mean that a substantial portion of India’s middle class never faces a tax bill at all. Understanding these seven changes is how you ensure that you are in that position from April 1.

Frequently Asked Questions
A: For most individual taxpayers, no immediate action is required specifically because of the Act replacement. Your tax obligations, rates, and deductions are identical. The change is primarily structural — the law is cleaner and simpler. What you do need to do is ensure your tax planning for FY 2026-27 uses the updated slab rates and that you understand the new ‘Tax Year’ terminology on ITR forms and communications.
A: Yes, but with important nuances. The ₹12 lakh zero-tax benefit applies only under the new regime, only to resident individuals (not NRIs or HUFs), and only to income NOT taxed at special rates. 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 even if your total income is below ₹12 lakh. The Section 87A rebate does not apply to those gains.
A: You can now file an ITR-U (Updated Return) within 48 months of the end of the relevant tax year to disclose income you missed or correct errors — paying additional tax plus a surcharge that increases with delay. For example, for Tax Year 2023-24, you can file an updated return up to March 2028. This is a significant amnesty-like provision that reduces prosecution risk for voluntary disclosures. Note that you cannot file an ITR-U to claim a larger refund — it is only available to disclose additional tax payable.
A: No. The education allowance (and the proposed increase to ₹3,000/month per child) is only available under the old tax regime. The new regime does not allow salary allowance exemptions — it replaces them with a flat ₹75,000 standard deduction. If the education and hostel allowances are significant for your household, factor them into your old vs new regime comparison after the IT Rules 2026 are formally notified.
A: The due date for filing ITR-1 and ITR-2 (most individual taxpayers) remains July 31, 2027 for Tax Year 2026-27. The tax audit deadline remains October 31, 2027. The window for revised returns has been extended — revised returns can now be filed up to 12 months from the end of the relevant tax year. Belated filers under the new Act can also claim TDS refunds, which was a previously unaddressed gap in the 1961 Act.
