Income Tax Act 2025 Explained:
What Budget 2026 Actually Changes

The Income Tax Act 2025 replaces the 1961 Act from April 1, 2026, bringing India's first new tax law in 64 years. The income tax slabs for FY 2026-27 stay unchanged, with the same new tax regime default and same Section 87A rebate. Budget 2026 made no headline slab changes. Several investment rules were, however, quietly and significantly rewritten. This guide covers every verified number, because for tax planning, the difference between understanding and guessing can cost you lakhs.

But here is the thing: while salaried taxpayers got silence, investors got a lot of news. Some good. Some expensive. This guide cuts through the Budget noise and tells you, with actual numbers and not vague summaries, what FY 2026-27 means for your tax bill.

The Big Picture

Budget 2026: The Tax Verdict at a Glance

Finance Minister Nirmala Sitharaman's Budget 2026 can be summarised in one line for income taxes: stability on rates, reform on compliance, and significant tweaks on investments. The Income Tax Act 2025, passed by Parliament in August 2025, comes into force from April 1, 2026, replacing the 64-year-old Income Tax Act 1961. This new Act is not a tax overhaul. It is a structural renovation of a building whose rooms stay exactly where they were.

Budget 2026 delivered the most structurally significant income tax change in India's history , not in the form of rate cuts or slab adjustments (there were none), but in the replacement of the entire legislative foundation. The Income Tax Act, 1961 governed India's tax system for 65 years, accumulating 700+ sections across decades of amendments. It became so complex that even tax professionals needed section-by-section reference guides to navigate it. The Income Tax Act, 2025, passed by Parliament in August 2025, replaces this entirely from 1 April 2026. The new Act has 536 sections organised across 23 clearly defined chapters , a 24% reduction in sections achieved by removing redundant provisions and consolidating related rules. Crucially, the reform is revenue-neutral: your actual tax liability is unchanged. The intent is structural simplification, not tax policy change. For the average salaried Indian, the most visible immediate change is that their Form 16 will now show "Tax Year 2026-27" instead of "Assessment Year 2027-28" , a small terminological shift that eliminates a confusion that has existed for decades. Use the Income Tax Calculator to verify your tax liability for FY 2026-27 is identical to FY 2025-26 at the same income and deductions.

The Hidden Cost

Why "No Change" Hides an 80C Inflation Erosion Problem

When the government says "no change in slabs," most people exhale in relief and move on. But for the salaried middle class, status quo is quietly costly.

Your salary grew. Your appraisal was 8-12%. So your taxable income crept upward, possibly into a higher band. Your ₹75,000 standard deduction buys less because inflation has been running at 6%. And the 80C limit of ₹1.5 lakh? That cap was set in FY 2014-15 That was eleven years ago. Had it been indexed to 6% inflation, it would be ₹2.85 lakh today. In real purchasing power, the ₹1.5L cap you claim is equivalent to just ₹79,000 in 2014 money. The government did not raise your taxes. Inflation did it for them.

The 80C limit of ₹1.5 lakh has remained unchanged since 2014. In 2014, ₹1.5 lakh was approximately 12.5% of a ₹12L annual salary. In 2026, ₹1.5 lakh is approximately 6.25% of a ₹24L annual salary , the same deduction, half the proportional value. Inflation has eroded 80C's effectiveness in real terms by 50% over 12 years, even though its nominal value appears unchanged. The same applies to Section 80D medical premium deduction: ₹25,000 for self and family (below 60) was introduced in 2015. Health insurance premiums have risen approximately 10-15% annually since then. ₹25,000 in 2015 covered a ₹10L family floater. ₹25,000 in 2026 might cover only ₹5L coverage for the same family. The deduction limit has stayed flat while healthcare costs have doubled. Under the Income Tax Act, 2025, these limits retain the same nominal values (now under Section 123 for old 80C, Section 124 for old 80D). No inflation adjustment is announced. For taxpayers in the old regime, this makes the deduction-driven tax saving strategy progressively less effective in real terms each year , strengthening the new regime's mathematical advantage for mid-income earners. The old vs new tax regime guide has the break-even analysis showing exactly at which deduction level the old regime still wins.

Verified Slabs

New Tax Regime Slabs FY 2026-27 , The Correct Table

The original article on this topic had an error I want to correct directly: the new regime is not "tax-free up to ₹3 lakh." The basic exemption under the new regime is ₹4 lakh for all individuals regardless of age. With the Section 87A rebate, zero tax is available on taxable income up to ₹12 lakh. Here are the confirmed, verified slabs for FY 2026-27:

Both regimes are unchanged for FY 2026-27. New regime is the default. Old regime must be actively chosen. The new regime is also available for senior citizens, though the beneficial exemption limits for seniors (₹3L for 60-80 years, ₹5L for 80+) apply only under the old regime.

The new regime's 85% suitability claim for incomes under ₹20L is driven by two specific factors. First, the ₹12L zero-tax threshold via Section 87A rebate (₹60,000 rebate wiping out all tax liability up to ₹12L taxable income) , effectively making the first ₹12L of taxable income completely tax-free. Second, the absence of deduction documentation: no Form 12BB declarations, no investment proofs, no HRA rent receipts, no home loan certificates. For salaried employees who do minimal tax-saving investments and have no home loan, the new regime requires zero paperwork and delivers zero tax up to ₹12.75L effective income (after ₹75,000 standard deduction). Under the Income Tax Act, 2025, the new regime is covered under Section 202 (previously Section 115BAC under the 1961 Act). The section number changed; the rules are identical. Use the Salary Breakup Calculator to separate your CTC into components and identify which portion falls under which slab , the difference between ₹12L taxable and ₹12L CTC can be significant depending on your employer's pay structure and applicable exemptions.

Zero Tax Zone

The ₹12.75 Lakh Zero-Tax Reality , How It Actually Works

This is the number everyone shares on WhatsApp, sometimes correctly and often with wrong assumptions. Let me show you exactly how a ₹12.75 lakh gross salary produces zero income tax.

The New Law

Income Tax Act 2025 vs 1961 , What Actually Differs

This is where most coverage gets lazy. "New Act replaces old one". Yes, but how? What does this mean for the person filing ITR in July 2026?

The Income Tax Act 1961 had expanded over 64 years into a labyrinth of 700+ sections, sub-sections with alphabets (80C, 80CCC, 80CCD…), provisos buried inside provisos, and circular references that even chartered accountants found difficult. The new Act brings this down to 536 sections, not because provisions were removed, but because overlapping provisions were consolidated, redundant ones deleted, and the rest rewritten in plain, numbered sequences.

The most impactful change for everyday taxpayers: the "Tax Year" concept. Under the old law, income earned in "Previous Year" (April–March) was taxed in "Assessment Year" (the following April–March). This caused endless confusion, especially when filing deadlines and notices referred to different year labels. Under the new Act, the Tax Year is simply the 12-month period (April to March) in which income is earned. One year, one label. Much cleaner.

Regime Decision

Old vs New Regime: Verified Math for Different Incomes

The only question most salaried Indians actually need answered: which regime should I choose? Here is the verified old vs new regime comparison for ₹15 lakh, ₹20 lakh, and ₹25 lakh earners in FY 2026-27, with exact calculations at common income levels and not the vague "it depends" answer. We also show income levels. All figures use standard deduction of ₹75,000 (new) and ₹50,000 (old), plus 4% health and education cess on final tax.

The verdict is clearer than most people think: At every income level from ₹10L to ₹25L, the new regime wins, even when the old regime gets realistic deductions of ₹2L (80C + std ded) or ₹4L (80C + std ded + HRA/home loan). The old regime can only beat the new regime at ₹20L+ if your total deductions genuinely exceed ₹6.5–7L, which requires paying a home loan and claiming HRA simultaneously, plus maxing out 80C, 80D, and NPS. For most salaried employees, new regime is the rational default.

If you are unsure, the Salary Breakup Calculator can show you what your actual take-home looks like under each regime based on your CTC structure. For a deep-dive with more income scenarios, deduction combinations, and worked examples, read our dedicated New vs Old Tax Regime guide for FY 2026-27.

Senior Citizens

80TTB Senior Citizen FD Interest Deduction in FY 2026-27 , Unchanged at ₹50,000

Under Section 80TTB (available under the old tax regime), senior citizens above 60 can deduct interest income from bank savings accounts and FDs. Despite widespread expectations, Budget 2026 left this limit unchanged at ₹50,000. No doubling occurred. This missed expectation leaves retirees with the same tax on FD interest as last year. For a deeper look at how FD returns get eroded after tax and inflation, see our Why FDs Fail Against Inflation guide.

The ₹1 lakh TDS threshold on senior citizen interest income (up from ₹50,000) under the Income Tax Act, 2025 is particularly significant for retired individuals who depend on FD and savings account interest as primary income. Under the old Act, banks deducted TDS once FD interest crossed ₹50,000 annually , triggering unnecessary TDS for seniors whose total income was still within the zero-tax limit (₹3L basic exemption + ₹50K standard deduction + ₹50K 80TTB deduction = ₹4L effectively tax-free for seniors in old regime). Raising the TDS threshold to ₹1L reduces avoidable TDS deductions and the subsequent refund process for senior citizens with total income under ₹5L. Additionally, Form 15G and 15H , previously two separate declarations for individuals vs senior citizens to prevent TDS , have been merged into a single Form 121 under the new Act, reducing paperwork. Senior citizens in the old regime can now benefit from: ₹3L basic exemption (vs ₹2.5L for others). ₹50,000 standard deduction. ₹1L 80TTB deduction on interest income. ₹50,000 80D deduction for medical insurance. Total tax-free income up to ₹4.5L (old regime) or ₹12L via Section 87A (new regime). Use the SCSS Calculator and NPS Calculator to model post-retirement income from government schemes alongside this revised TDS framework.

Gold Investments

Sovereign Gold Bonds: Tax Exemption at Maturity Still Intact

Sovereign Gold Bonds were the smartest gold investment for one specific reason: capital gains on maturity (after 8 years) were completely tax-exempt for individual investors. That exemption largely continues, but the rules around early exits have evolved significantly.

• Held to maturity (8 years): Capital gains remain exempt for individual investors. Still the best reason to hold SGBs to term. Interest of 2.5% per annum is taxable as income in the year received.
• Sold in secondary market before maturity: Post the 2024 changes to indexation removal, SGB transfers in the secondary market are taxed without indexation benefit, likely at the concessional capital gains rate (12.5% for LTCG). No indexation means you pay tax on the full nominal gain, not the inflation-adjusted gain.
• Premature redemption through RBI (allowed after 5 years): Still exempt from capital gains for individuals, though exact rules are subject to specific SGB series conditions.

The SGB redemption exemption at maturity (8 years) remains fully intact under the Income Tax Act, 2025. This is one of the most tax-efficient investment exits available to Indian investors: capital gains on SGB redemption at RBI maturity are completely tax-free , no LTCG, no STCG, no indexation required. This exemption applies only to RBI-maturity redemption, not to secondary market sale of SGBs (which attracts LTCG at 12.5% with ₹1.25L exemption). The SGB scheme has been paused since early 2024 with no new tranche announced in Budget 2026. However, existing SGBs continue to mature over the next 6-8 years, and the exemption is confirmed under the new Act. Investors holding SGBs purchased between 2016-2024 should track their maturity dates carefully. Premature redemption (after 5 years but before 8) is allowed by RBI at market price, but the gains are taxed as LTCG unlike maturity redemption which is tax-free. Early redemption surrender the tax exemption and should only be done for genuine liquidity needs. The capital gains tax guide covers the complete tax treatment of SGBs across maturity, premature redemption, and secondary market scenarios , the difference in tax liability across these three exit routes can be substantial.

Equity Investing

Share Buybacks: The End of Tax-Free Corporate Exits

This is the change that quietly reshuffled the return calculations for many equity investors. Until October 2024, buybacks operated on a clever structure: the company paid a buyback tax at the corporate level, and shareholders received their proceeds completely tax-free. High-income investors loved it. Some companies preferred it over dividends precisely because shareholders could receive money without adding it to their taxable income.

Budget 2026 reversed that October 2024 change: share buyback proceeds are now taxed as Capital Gains in the shareholders' hands, not as dividend income. The profit (buyback price minus your purchase price) is taxed at 12.5% for LTCG (held over 12 months) or 20% for STCG. This is confirmed by the official Budget 2026 PIB release.

For long-term investors in dividend-paying companies, this matters less directly. But it changes corporate behavior: companies that previously used buybacks to return cash might now shift back to regular dividends, which are taxed identically. The net effect for shareholders is the same, but watch for changes in how your portfolio companies announce capital allocation. For LTCG implications on equity holdings broadly, our Capital Gains Tax India guide has the full breakdown.

The buyback tax change from Budget 2024/2025 is now enshrined in the Income Tax Act, 2025. Previously, companies paid an additional 20% buyback distribution tax , shareholders received buyback proceeds tax-free. From FY 2024-25 onwards (and continuing under the new Act), buyback proceeds are treated as dividend income in the shareholder's hands, taxed at their applicable income slab rate. For a 30% bracket investor, this shifts the effective tax on buyback from 0% to 30% , a dramatic change affecting anyone holding stocks of companies that regularly return capital via buybacks. Additionally, Budget 2026 introduces an additional promoter-level tax on buybacks, making the structure even less attractive for companies that use buybacks as a capital return tool. Practically: if your stock announces a buyback, the tender offer proceeds are now taxable income, not capital gains. The ₹1.25L LTCG exemption does not apply. The proceeds are added to your total income and taxed at your marginal rate. For investors holding MNC stocks or large-cap companies known for buybacks (Infosys, TCS, HUL, etc.), this requires a post-tax calculation before deciding whether to tender shares in a buyback offer or simply hold for market sale. Use the capital gains tax guide and the Income Tax Calculator to compare the net proceeds from tendering vs holding for each buyback offer you receive.

F&O Trading

STT Hike on Futures: Breakeven Cost for F&O Traders in 2026

If you trade Futures & Options, this change hits your breakeven directly. The Securities Transaction Tax (STT) on futures contracts has been raised from 0.02% to 0.05%, a 2.5× increase. The government's stated intent is clear: reduce the speculative retail participation in F&O that SEBI has been concerned about for two years.

For a moderately active trader taking 2 trades per day on a ₹1 Crore position, across 20 trading days a month: that is 40 round trips × ₹3,000 extra = ₹1,20,000 additional monthly cost from STT alone. Over a year: ₹14,40,000. Before you make a single profitable trade. The math now demands either larger positions, higher win rates, or both, none of which retail traders should take as a signal to trade bigger.

The STT (Securities Transaction Tax) hike on F&O trades has a cascading effect on breakeven calculations for active traders. STT is paid regardless of profit or loss , it is a transaction cost on every trade. For a futures trader executing ₹10 crore in notional value per month, STT at the new rate adds approximately ₹10,000-15,000 in additional cost per month (₹1.2-1.8L annually) vs the old rate. This cost is deductible from business income for tax purposes (if F&O is declared as business income, which it should be for active traders), but it still represents real cash outflow on every trade. The breakeven point for any F&O position has moved up by the STT increment on entry and exit combined. Additionally, F&O losses cannot be set off against salary income , they can only be carried forward for 8 tax years against future F&O or capital gains income. Under the Income Tax Act, 2025, all TDS provisions are consolidated under Section 393 (previously scattered across Sections 192, 194, 194A, etc.). This consolidation doesn't change rates but makes the law significantly easier to navigate. The TDS Calculator has been updated for the new section numbers and thresholds effective from Tax Year 2026-27. Traders should verify their advance tax calculations include the higher STT as a deductible expense to avoid under-payment penalties.

NRI Rules

NRI Property Sales: Simplified TDS , But Watch Liquidity

If you are an NRI selling property in India, or a resident buying property from an NRI, Budget 2026 brings a genuinely helpful procedural change, and one important caution.

What changed (good): Buyers of property from NRIs no longer need to obtain a Tax Deduction Account Number (TAN) for TDS compliance. They can now use a PAN-based challan to deduct and deposit TDS. This removes a significant administrative burden, especially for individual buyers who previously had to apply for TAN through a cumbersome process.

The caution: TDS rates on NRI property sales remain significant, typically 20% (plus applicable surcharge and cess) on the sale value if no lower deduction certificate is obtained. This means a large chunk of sale proceeds is blocked with the Income Tax department until the NRI files their return and claims a refund, which can take months. If you are an NRI planning to reinvest proceeds quickly (say, into a new property under Section 54), factor in this liquidity gap in your planning. Our TDS Calculator can help estimate the deduction before you finalise a sale or purchase agreement.

The PAN-based challan for NRI property sale TDS eliminates a major compliance barrier. Previously, a buyer purchasing property from an NRI had to obtain a TAN (Tax Deduction Account Number), file a separate TDS return, and comply with Form 27Q requirements , a process that could take weeks and required professional assistance. The new PAN-based challan under Section 194IA (renumbered under the 2025 Act) allows buyers to simply enter the seller's PAN, calculate TDS (20% on sale value for NRIs without a lower TDS certificate, vs 1% for resident Indians), and deposit via a straightforward challan. This simplification reduces the transaction friction of buying property from NRIs significantly. However, the tax rate itself (20% TDS on full sale value for NRIs) remains unchanged. NRIs selling property in India still face 20% TDS regardless of actual capital gain , they must apply for a lower TDS certificate from the Income Tax Department before the sale to avoid TDS on the gross sale value vs the actual capital gain. Without this certificate, a buyer must deduct 20% of ₹1 crore sale price = ₹20L TDS, even if the NRI's actual capital gain is only ₹10L. The simplified PAN challan doesn't resolve this underlying issue. The capital gains tax guide covers the NRI property sale TDS structure in detail, including how to apply for a lower TDS certificate and the timeline involved.

Filing Dates

Extended Filing Deadlines: Who Benefits and How Much

Budget 2026 extends two important filing deadlines, one of which is a genuine relief for freelancers and small business owners who always felt the ITR-3/ITR-4 July 31 deadline was impossibly tight.

The revised return extension to 31 March is quietly the most useful change for salaried taxpayers. If you made a mistake in your original July filing (missed a deduction, forgot an income source, or got a Form 16 correction), you now have until March 31 to file a corrected return instead of rushing to December. Note that revised returns filed after December 31 attract an additional fee.

The ITR-3 and ITR-4 deadline extension to 31 August (from 31 July) benefits two groups specifically: small business owners and self-employed professionals who file ITR-3/4 but do not require a tax audit (audit cases retain the 31 October deadline). For freelancers, consultants, and small traders who previously struggled with the July 31 deadline during the monsoon season when businesses are busy, the August 31 date provides a meaningful 31-day buffer. However, ITR-1 (salaried with no business income) and ITR-2 (salaried with capital gains) retain the 31 July deadline. The deadline for revised returns has also been extended to 31 March of the following year (previously 31 December), with a nominal fee applicable for revisions made after 31 December. This is practically useful: if you receive an AIS (Annual Information Statement) discrepancy notice in January or February, you can now file a revised return to correct it rather than being locked out of the revision window. Under the old system, missing the December 31 revised return deadline meant the error could only be corrected via the assessment process. Use the Income Tax Calculator early in the tax year , ideally by May when your Form 16 is available , so you have time to correct any errors before even the August deadline.

Action Plan

Tax Strategy Moves for FY 2026-27

Given everything above, here is what to actually do, not what to research endlessly.

1. Do the regime comparison in April, not July. Most people wait till filing time. By then, it's too late to restructure salary components like NPS employer contribution, which is only beneficial under the new regime if your employer offers it. Decide in April, inform HR, and lock in the right TDS treatment for the full year.
2. Hold SGBs to maturity. Secondary market sales are no longer the clean exit they once were. If you own SGBs with 1-3 years remaining, hold them through the exemption window unless liquidity is urgent.
3. Re-evaluate dividend vs buyback stocks. Both are now taxed identically in your hands. The choice between dividend-paying and buyback-friendly companies can now be made purely on business fundamentals rather than tax structuring.
4. F&O traders: recalculate breakeven. Add ₹1.2L+ to annual cost assumptions for a ₹1Cr position size. If your strategy doesn't generate comfortably more than this, revisit the approach. Real Return Calculator helps quantify net-of-cost returns across strategies.
5. Senior family members: re-evaluate the new regime. Because Section 80TTB was NOT hiked (stays at ₹50K), the new regime's ₹4L basic exemption and wider slabs will actually result in lower taxes for many seniors. Model both options before filing's seemingly simpler slabs. Model both options before filing. Our retirement planning guide covers income tax for retired individuals in detail.
6. NRI property sellers: get a lower deduction certificate. If you are an NRI planning to sell Indian property, apply for a lower TDS certificate from the assessing officer before the sale. This can reduce TDS from 20%+ to a rate closer to your actual liability, avoiding months of liquidity being locked with the department.

14. Section Renumbering Reference , Old 1961 vs New 2025

The most practically confusing aspect of the Income Tax Act, 2025 for taxpayers and professionals is that every section number has changed. The underlying rules are identical , but when your CA, payroll software, or bank form references Section 80C, you now need to know it corresponds to Section 123 under the new Act. FY 2025-26 returns (filed by July 2026) still use old section numbers. FY 2026-27 returns (filed from July 2027) use new section numbers. Here is the quick reference for the most commonly used sections:

The Income Tax Department has published a section mapping utility at incometaxindia.gov.in that cross-references every 1961 Act section to its 2025 equivalent. Taxpayers filing FY 2025-26 returns in 2026 should use old section numbers , the new sections apply only from Tax Year 2026-27 onwards. Payroll software, CA firms, and banking platforms will update their references by Q1 FY 2026-27, but there may be a transitional period of confusion. The Income Tax Rules, 1962 are simultaneously replaced by Income Tax Rules, 2026 , reduced from 500+ rules to 333 rules. Both the Act and Rules take effect simultaneously from 1 April 2026. For any tax-saving investment decisions (PPF, ELSS, NPS), the underlying deduction limits and lock-in periods are unchanged , only the section references change. Use the PPF Calculator, NPS Calculator, and Income Tax Calculator , all updated for the new Act's terminology and thresholds. The HRA exemption guide has been updated to reflect the expanded metro list under Income Tax Rules, 2026 adding Bengaluru, Hyderabad, Pune, and Ahmedabad to the 50% HRA city tier.
