New Income Tax Rules from April 1, 2026

April 1, 2026 is not just another new financial year. It is the single most significant overhaul of India's direct tax architecture in over six decades. The Income Tax Act, 1961 — drafted in the Nehru era, amended 65 times, swollen to 819 sections across 47 chapters — formally ceases to be the law. It is replaced by the Income Tax Act, 2025: a cleaner, 536-section statute built for a digital economy, designed for ordinary citizens, and aimed at reducing the legal disputes that have clogged India's tax tribunals for years. On top of the new law, Budget 2026 has layered several targeted changes to STT, TCS, buyback taxation, ITR deadlines, and more. Here is every single change you need to know before April 1.

Income Tax Slabs for FY 2026-27 — What Stays, What Changes

The good news: tax slab rates are unchanged. The new regime slabs introduced in Budget 2025 continue as the default for FY 2026-27. The zero-tax limit of Rs. 12 lakh under the new regime (Rs. 12.75 lakh for salaried individuals after the Rs. 75,000 standard deduction) remains fully intact. No new tax slabs, no changes to deduction limits under Section 80C or Section 80D.

Income Range	New Regime Tax Rate	Old Regime Tax Rate
Up to Rs. 4 lakh	Nil	Nil (up to Rs. 2.5L)
Rs. 4 lakh to Rs. 8 lakh	5%	5% (Rs. 2.5L to Rs. 5L)
Rs. 8 lakh to Rs. 12 lakh	10%	20% (Rs. 5L to Rs. 10L)
Rs. 12 lakh to Rs. 16 lakh	15%	30% (above Rs. 10L)
Rs. 16 lakh to Rs. 20 lakh	20%	30%
Rs. 20 lakh to Rs. 24 lakh	25%	30%

1. Income Tax Act, 2025 Replaces the 1961 Law — What It Means

The Income Tax Act, 1961 is replaced by the Income Tax Act, 2025, effective April 1, 2026. The new Act does not change your tax rates, deductions, or exemptions — it restructures the law itself. The 819-section, 47-chapter old law is replaced by a 536-section statute with plain language, logical sequencing, and removal of redundant provisions. The Income Tax Rules, 1962 (which had 500+ rules) are simultaneously replaced by the Income Tax Rules, 2026 — reduced to just 333 rules.

• What changes for most individual taxpayers: Almost nothing in terms of actual tax liability — rates, deductions, and exemptions are identical
• What changes for professionals (CAs, tax lawyers): Section numbering changes entirely — all references in software, forms, and advisories will update. Expect temporary navigation confusion as the ecosystem catches up
• What changes for businesses: Companies need to review deferred tax positions, update compliance software, and map pending assessments under the old Act before the transition window
• FY 2025-26 (AY 2026-27) returns: Still filed under the old Income Tax Act, 1961. Your first return under the new Income Tax Act, 2025 will be filed from July 2027 for Tax Year 2026-27

2. Single Tax Year Replaces Previous Year and Assessment Year

One of the most taxpayer-friendly changes is the replacement of two confusing terms — Previous Year and Assessment Year — with a single unified concept called Tax Year. Under the old system, income earned in Previous Year 2025-26 was assessed in Assessment Year 2026-27. This two-year terminology confused millions of filers. From April 1, 2026, the year in which you earn income is simply called the Tax Year — and you file your return within the same Tax Year.

• Tax Year 2026-27 = April 1, 2026 to March 31, 2027 — income earned and filed within this period
• Your Form 16 will now show Tax Year 2026-27 instead of Assessment Year 2027-28
• Loss carry-forward: Losses can still be carried forward for 8 Tax Years. A loss in Tax Year 2026-27 can offset income up to Tax Year 2034-35
• Appeal deadlines: Now counted within the same Tax Year as the notice — 30 days from the date of notice

3. Extended ITR Filing Deadlines — ITR-3 and ITR-4 Now Due August 31

A significant relief for business owners, freelancers, and professionals: the due date for filing ITR-3 and ITR-4 (for non-audit cases) has been extended from July 31 to August 31. This gives an extra month to business taxpayers who need more time to finalise books of accounts before filing. The ITR-1 and ITR-2 deadlines for salaried and capital gains filers remain July 31. Audit cases remain October 31.

• Revised return deadline: Extended from 9 months to 12 months from the end of the Tax Year — giving filers until December 31 to correct errors. A late fee applies if the revised return is filed after 9 months: Rs. 1,000 if total income is below Rs. 5 lakh, or Rs. 5,000 otherwise

4. STT Hike on Futures and Options — Higher Trading Costs from April 1

F&O traders face meaningfully higher transaction costs from April 1, 2026. The Securities Transaction Tax on futures contracts increases from 0.02% to 0.05% — a 2.5x jump — while STT on options transactions increases from 0.1% to 0.15% on the sell side. The government's stated objective is to discourage excessive speculation in derivatives markets, where retail participation has surged dramatically over the past three years.

• Futures STT: 0.02% to 0.05% — on the sell side of futures contracts
• Options STT: 0.1% to 0.15% — on the sell side of options contracts (premium value)
• Impact: Active F&O traders will see a direct increase in transaction costs. A trader executing Rs. 1 crore in futures notional daily will pay Rs. 500 more in STT per day — Rs. 1.25 lakh more per year
• Context: STT paid on F&O is a business expense and deductible against business income for traders who declare F&O as business income

5. Share Buyback Now Taxed as Capital Gains — Not Dividend

This is a major shift for equity investors and promoters. Previously, amounts received from share buybacks were treated as deemed dividends and taxed at the investor's applicable slab rate. From April 1, 2026, buyback proceeds are taxed as capital gains — aligning buyback taxation with all other equity transactions.

• For retail investors: If shares are held more than 12 months, buyback gains taxed at 12.5% LTCG (above Rs. 1.25 lakh exemption). If held less than 12 months, STCG at 20% — both potentially lower than the earlier slab-rate treatment for high-income investors
• For promoters (individuals): Effective tax rate of approximately 30% plus surcharge and cess
• For promoter companies: Effective tax rate of approximately 22% plus surcharge and cess
• Key implication: Companies that use buyback as an alternative to dividend distribution need to recalibrate their capital return strategy based on the new tax treatment

6. Sovereign Gold Bond Gains — Secondary Market Buyers Now Taxed

Earlier, capital gains on redemption of Sovereign Gold Bonds at maturity were fully exempt for all SGB holders. From April 1, 2026, this exemption is narrowed: it applies only to investors who subscribed to SGBs in the original issue directly from the RBI. Investors who purchased SGBs from the secondary market (BSE/NSE) will have their redemption gains taxed as capital gains — at 12.5% if held long term (more than 36 months), or at slab rate if held short term.

• Original issue subscribers: Maturity redemption gains remain fully exempt — no change
• Secondary market buyers: Gains on maturity now taxed as capital gains — significant change for investors who bought SGBs at a discount on exchanges
• Action point: If you hold SGBs bought from the secondary market, factor this tax into your return calculation. Consider whether to hold to maturity or exit before the new rules take effect

7. Other Notable Changes — TCS, MAT, Dividends, NRI TDS, Perquisites

TCS Rationalisation

• Multiple TCS rates across categories simplified to a uniform 2% — reducing confusion for businesses and importers. This follows the government's ongoing effort to reduce TCS-driven refund delays for taxpayers

MAT Reduced for Companies

• Minimum Alternate Tax reduced from 15% to 14% for companies. Critically, companies will not be allowed to accumulate new MAT credit after March 31, 2026. Existing MAT credits accumulated before April 1, 2026 can still be utilised under current rules

No Interest Deduction Against Dividend Income

• Earlier, taxpayers could deduct interest expenses (up to 20% of dividend income) while computing taxable dividend income. From April 1, 2026, this deduction is removed. Investors who have borrowed funds to purchase dividend-yielding shares will face higher taxable income

NRI Property TDS — No TAN Required

• Buyers purchasing immovable property from an NRI can now deduct TDS under Section 194IA by obtaining a simple PAN-based challan — eliminating the earlier requirement to obtain a TAN registration. A significant compliance simplification for property buyers

Armed Forces Pension Tax Change

• Tax exemption on pension for armed forces personnel will now apply only to those discharged due to physical disability. Regular retirement pensions of armed forces personnel will no longer qualify for exemption — a change that affects a large number of defence retirees

Meal Vouchers — Higher Tax-Free Limit

• Meal vouchers provided by employers are now tax-free up to Rs. 200 per meal per day (increased from the earlier outdated limit). This applies under the new tax regime as a perquisite benefit for salaried employees

FAQs

Q1. Is income up to Rs. 12 lakh still tax-free from April 1, 2026?

• Yes. The enhanced Section 87A rebate of Rs. 60,000 ensuring zero tax liability for resident individuals with taxable income up to Rs. 12 lakh under the new regime continues unchanged for FY 2026-27. For salaried individuals, the effective zero-tax limit is Rs. 12.75 lakh after the Rs. 75,000 standard deduction. Tax slab rates under both the old and new regimes are also fully unchanged for FY 2026-27.

Q2. What is the Tax Year concept in the Income Tax Act, 2025?

• The Income Tax Act, 2025 replaces the two confusing terms — Previous Year and Assessment Year — with a single concept called Tax Year. The Tax Year runs from April 1 to March 31, just like the financial year. Income earned in Tax Year 2026-27 (April 1, 2026 to March 31, 2027) is filed and assessed within the same Tax Year. This eliminates the confusion of earning in one year and assessing in another.

Q3. What are the new ITR filing deadlines from April 1, 2026?

• ITR-1 and ITR-2 (salaried and capital gains filers): July 31 — unchanged. ITR-3 and ITR-4 (business income, non-audit cases): extended to August 31 — a full extra month. Tax audit cases: October 31 — unchanged. Transfer pricing cases: November 30 — unchanged. Revised and belated returns: December 31 — extended from 9 months to 12 months from the end of the Tax Year.

Q4. How does the STT hike affect F&O traders from April 1, 2026?

• The STT on futures contracts increases from 0.02% to 0.05% (a 2.5x hike) and on options contracts from 0.1% to 0.15% on the sell side. This directly increases the transaction cost for all F&O traders. For a trader with Rs. 1 crore in daily futures notional, STT increases by Rs. 500 per day — approximately Rs. 1.25 lakh per year. F&O traders who declare trading as a business can deduct STT as a business expense against their income.

Q5. How are share buyback proceeds taxed from April 1, 2026?

• From April 1, 2026, amounts received from share buybacks are taxed as capital gains — not as deemed dividends. For retail investors: if shares are held more than 12 months, LTCG at 12.5% (above Rs. 1.25 lakh annual exemption). If held under 12 months, STCG at 20%. For promoters (individuals), the effective rate is approximately 30%. For promoter companies, approximately 22%. This change aligns buyback taxation with all other equity transactions
