New Income Tax Act 2025 — Everything That Changes from April 1, 2026

By CalcBaba Team6 min read

On April 1, 2026, India will officially bid farewell to the Income Tax Act of 1961 — a piece of legislation that governed the country's tax framework for 65 years. In its place, the newly enacted Income Tax Act 2025 will come into force. If you're a salaried employee, business owner, freelancer, or investor in India, here is everything you need to know — explained in plain, simple language.

What is the New Income Tax Act 2025?

The Income Tax Act 2025 was passed by Parliament to replace the Income Tax Act 1961, which had become bloated over six decades with thousands of amendments, provisos, and explanations that made tax compliance a nightmare for ordinary citizens. The new act comes into force from April 1, 2026 (Tax Year 2026-27).

The primary objective is to simplify tax laws, reduce legal complexity, consolidate scattered provisions, and make compliance easier for the average Indian taxpayer. The 1961 act had around 298 sections and 23 chapters — the new act has reorganized these into a leaner, more logical structure with simplified language.

The most important thing to understand: Tax rates and slab structures remain completely UNCHANGED. This is a restructuring of rules, definitions, and procedures — not a tax hike. Your take-home salary will not be affected by this change alone.

What Stays the Same — Don't Panic

Before we discuss what's new, let's clarify what does NOT change:

  • Tax slabs remain identical to FY 2025-26 — zero tax up to ₹12.75 lakh for salaried individuals under the new regime.
  • New regime remains the default — you don't need to opt in again.
  • Section 80C, 80D deductions continue to be available in the old regime.
  • ITR filing deadline is still July 31 for most individual taxpayers.
  • Old vs new regime choice is still available — salaried employees can switch every year.
  • Standard deduction of ₹75,000 continues under the new regime.

Key Changes That Affect Salaried Employees

1. New Concept of “Tax Year”

The old system used two separate concepts — “Financial Year” (the year you earn income) and “Assessment Year” (the year you are assessed/file ITR). This caused confusion for millions of taxpayers who could never remember whether it was FY 2025-26 or AY 2026-27.

The new act replaces both with a single concept: Tax Year. Tax Year 2026-27 = April 1, 2026 to March 31, 2027. One term, one period, no confusion. This is purely a naming simplification — it does not change how income is calculated.

2. Revised Return Deadline Extended

Under the old act, you could revise your ITR only until December 31 of the assessment year. The new act extends this deadline — you can now revise your return until March 31 of the assessment year, giving you three additional months to correct errors.

A fee of ₹5,000 applies if your total income exceeds ₹5 lakh. If your income is ₹5 lakh or below, the fee is reduced to ₹1,000.

3. Perquisite Values Updated

The monetary thresholds for perquisites (taxable benefits provided by employers) have been revised after many years. Motor car perquisite values — which determine the taxable value of a company-provided car — have been updated to reflect current market realities. Free education perquisite limits have also been revised upward, providing relief for employees whose children study at employer-run institutions.

4. No TAN Required for Property Buyers

Previously, if you purchased property from a non-resident seller, you needed to obtain a Tax Deduction Account Number (TAN) to deduct TDS. Under the new act, the buyer can simply use their PAN instead of obtaining a separate TAN — removing an unnecessary bureaucratic step from property transactions.

Changes for Business Owners and Self-Employed

  • Penalty proceedings simplified: Under the old act, assessment orders and penalty orders were separate proceedings, often leading to years of litigation. The new act allows assessment and penalty to be issued in a single combined order, dramatically reducing the number of separate proceedings a taxpayer faces.
  • Pre-payment for disputes reduced: To pursue an appeal against a tax demand, businesses previously had to pre-pay 20% of the disputed demand. This has been reduced to 10%, making it significantly easier for small businesses to challenge erroneous tax demands without massive cash flow disruptions.
  • MAT rate reduced: The Minimum Alternate Tax (MAT) rate for companies opting for the new regime has been reduced from 15% to 14%, providing a small but meaningful reduction in the minimum tax burden for corporate entities.
  • Share buyback taxation changed: Share buyback proceeds are now taxed as capital gains in the hands of shareholders, rather than being treated as dividend income at the company level. This results in an effective tax rate of approximately 22% for corporate promoters and up to 30% for individual shareholders in the highest bracket.

What Changes for Investors

  • Share buyback = capital gains: As mentioned above, buyback proceeds are now treated as capital gains in the hands of investors, not dividend income. This changes the effective tax calculation for investors who hold shares in companies that frequently buy back stock.
  • Sovereign Gold Bond (SGB) capital gains exemption narrowed: The exemption on capital gains from SGBs now applies only if held from original issue to maturity. If you purchase SGBs from the secondary market (stock exchange), or redeem them prematurely, the capital gains exemption will NOT apply. Plan your SGB investments accordingly.
  • ITR filing declaration simplified: Investors can now file a no-deduction declaration directly with the depository (NSDL/CDSL) instead of filing separately with each individual deductor. This streamlines the process for investors with holdings across multiple brokers.

New Income Tax Slabs FY 2026-27 (Unchanged)

Despite the new act, the income tax slabs under the new regime remain identical to FY 2025-26. Here are the current rates:

Income Slab (Annual)Tax Rate
₹0 – ₹4,00,0000%
₹4,00,001 – ₹8,00,0005%
₹8,00,001 – ₹12,00,00010%
₹12,00,001 – ₹16,00,00015%
₹16,00,001 – ₹20,00,00020%
₹20,00,001 – ₹24,00,00025%
Above ₹24,00,00030%

Key: Standard deduction of ₹75,000 + Section 87A rebate of up to ₹60,000 means salaried individuals with income up to ₹12,75,000 pay absolutely zero tax under the new regime. These slabs are identical to FY 2025-26 — no change whatsoever.

Action Items — What You Should Do Before April 1, 2026

  1. Calculate your tax under both regimes for FY 2025-26 before March 31. Use our Income Tax Calculator to see which regime saves you more.
  2. Make last-minute 80C investments before March 31 — PPF contributions, ELSS mutual funds, LIC premium payments, and Sukanya Samriddhi deposits all qualify for up to ₹1.5 lakh deduction under the old regime.
  3. Pay advance tax final installment by March 15 (already due — verify if you've paid). Failure to pay attracts interest under Section 234C.
  4. File any pending ITR for FY 2024-25 before March 31. Belated returns for FY 2024-25 cannot be filed after this date. Missing this deadline means losing the right to carry forward certain losses.
  5. Calculate your FY 2026-27 tax under new rules to plan your TDS declarations with your employer early in April. Getting this right from Day 1 prevents end-of-year surprises.
