Income Tax Act, 2025 - Union Budget 2026 Key Personal Income Tax Changes (FY 2026-27)

The Income Tax Act, 2025, marks a significant milestone in India’s tax reforms, offering a more streamlined and transparent system for taxpayers. With the Union Budget 2026 laying the foundation for the financial year 2026–27, this updated legislation aims to simplify compliance while addressing the needs of salaried individuals, pensioners, freelancers, and the middle class. The government’s emphasis on modernisation and reform ensures that taxpayers can navigate the system with greater ease, while also aligning with the country’s economic goals.

This article delves into the key changes introduced under the Income Tax Act, 2025, as outlined in the Union Budget 2026, and their implications for individual taxpayers.

The Income Tax Act, 2025 comes into effect from April 1, 2026, bringing a comprehensive reform to India’s direct tax framework for FY 2026–27. A key highlight is the introduction of a single “tax year,” replacing the earlier concept of previous year and assessment year, which simplifies tax understanding and filing.

The new law focuses on clearer language and a more structured format, making provisions easier for taxpayers to interpret. While the overall personal income tax slabs and rates remain unchanged, the emphasis is on improving compliance and reducing complexity.

Additionally, return filing processes have been streamlined with simplified ITR forms and better-defined timelines. The Act also introduces improved reporting standards and tighter disclosure requirements to enhance transparency. Overall, these changes aim to create a more user-friendly, efficient, and modern tax system for individual taxpayers.

The Income Tax Act, 2025, is a comprehensive overhaul of India’s previous tax legislation. It aims to address the challenges of the older framework while introducing measures to simplify tax compliance and enhance transparency.

Why a new Income Tax Act was introduced

The previous Income Tax Act had been in effect for decades, making it increasingly complex and outdated. Over the years, numerous amendments and provisions had been added, leading to challenges in interpretation and implementation. The new Income Tax Act, 2025, was introduced to address these limitations and to align the tax system with the evolving economic landscape.

Objectives of the Income Tax Act, 2025

The primary objectives of the Income Tax Act, 2025, include:

• Simplifying tax compliance for individuals and businesses.
• Enhancing transparency and reducing ambiguities in tax laws.
• Encouraging voluntary compliance through streamlined processes.
• Promoting a digital-first approach to tax filing and documentation.

How Budget 2026 aligns with the new Act

The Union Budget 2026 complements the Income Tax Act, 2025, by introducing policy reforms that align with its objectives. These changes aim to make the tax system more efficient, equitable, and easier to navigate for taxpayers.

The Income Tax Act, 2025, is set to impact a wide range of taxpayers starting from the financial year 2026–27.

Who is covered under the new rules

The new rules apply to various categories of taxpayers, including:

• Salaried individuals across income brackets.
• Pensioners and senior citizens.
• Freelancers and self-employed professionals.
• Non-resident Indians (NRIs) earning income in India.
• Individuals earning income from investments, property, or other sources.

From when the new provisions apply

The provisions of the Income Tax Act, 2025, will come into effect from the financial year 2026–27, which corresponds to the assessment year 2027–28. The financial year (FY) refers to the period during which income is earned, while the assessment year (AY) is the year following the FY when the income is assessed and taxes are filed.

Key transition points taxpayers should note

Taxpayers should be mindful of the following key changes during the transition:

• Carry-forward of deductions and losses will be subject to revised rules.
• Investment declarations must align with the new provisions to avail of tax benefits.
• The transition will require individuals to reassess their tax-saving instruments and strategies.

One of the most anticipated aspects of the Union Budget 2026 is the revision of personal income tax slabs under the new regime.

Revised income tax slabs under the new regime

Below is the updated income tax slab structure for FY 2026–27:

Any changes in basic exemption limit

The basic exemption limit has been increased from Rs. 2,50,000 to Rs. 3,00,000 under the new regime. This change provides relief to low-income earners and encourages more individuals to opt for the new tax regime.

Comparison with previous year slabs

The coexistence of the old and new tax regimes offers taxpayers the flexibility to choose a system that best suits their financial profile.

Key differences in tax calculation

• Old Regime: Allows multiple exemptions and deductions, such as HRA and Section 80C benefits.
• New Regime: Offers lower tax rates but eliminates most exemptions and deductions.

Which regime is default for FY 2026–27

The new tax regime is the default system for FY 2026–27. However, taxpayers can opt for the old regime by submitting a declaration.

Comparison table

The Income Tax Act, 2025, brings notable changes to popular deductions and exemptions.

Section 80C and related deductions

The Rs. 1.5 lakh limit under Section 80C remains unchanged but is only applicable under the old regime.

House Rent Allowance and standard deduction

HRA and standard deduction benefits are retained under the old regime but are not available in the new regime.

Health insurance and medical expense benefits (Section 80D)

Section 80D deductions for health insurance premiums remain applicable under both regimes, with no changes to the limits.

Salaried individuals are among the most impacted by the new rules.

Salary structure and taxability changes

Revised rules on allowances and perquisites aim to simplify tax calculations for salaried taxpayers.

Impact on take-home salary

With lower tax rates in the new regime, take-home salaries may increase for those opting for this system.

Employer compliance and Form 16 changes

Employers must update Form 16 formats to reflect the new tax provisions and ensure accurate TDS deductions.

Presumptive taxation updates

For small businesses under section 44AD, the turnover limit for presumptive taxation has been raised to up to ₹3 crore, subject to cash receipts not exceeding 5% of total receipts. For specified professionals under section 44ADA (like doctors, lawyers, consultants, designers), the presumptive scheme is now available up to ₹75 lakh of gross receipts, again only if cash receipts stay within 5% of total receipts. Under 44ADA, 50% of gross receipts are deemed as taxable profit, and detailed books or audit are not required when you opt for this scheme.

Expense deduction rules

Self-employed taxpayers not using presumptive schemes can claim deductions for business expenses such as office rent, utilities, software, travel, and professional fees, provided they are wholly and exclusively for business. You must maintain proper documentation—invoices, agreements, payment proofs, and depreciation records for capital assets—for these expenses to be allowed if scrutinised. Personal or capital expenses (other than via depreciation) and any expenditure incurred for purposes prohibited by law are not deductible.

Advance tax and compliance changes

Self-employed individuals must pay advance tax if their total tax liability exceeds ₹10,000 in a year; those using presumptive schemes under 44AD/44ADA can discharge the entire advance tax by 15 March. Delay or short payment in earlier instalments usually triggers interest under section 234C, calculated for a full quarter, so estimating income and paying on time helps avoid penalties and cash-flow shocks. Recent Budget measures also aim to make compliance less adversarial by rationalising penalties and integrating assessment with penalty orders, reducing the burden of multiple proceedings on small taxpayers.tax2win+2

Equity and mutual fund taxation updates

For FY 2026–27, long-term capital gains on listed equity shares and equity-oriented mutual funds (holding period above 12 months) are taxed at 12.5%, with an annual exemption of ₹1.25 lakh on such gains. Short-term gains on listed equity (up to 12 months) attract 20%, while unlisted shares typically become long term after 24 months and are also taxed at 12.5% when long term. For many non-equity mutual funds (like older debt, gold, and certain hybrid schemes), the previous 20% with indexation has largely given way to a uniform 12.5% LTCG without indexation once they cross 24 or 36 months, depending on category and purchase date.

Property capital gains rules

On real estate, indexation benefits have been curtailed but not fully removed; for residential property acquired on or before 22 July 2024 and sold later, individuals can generally choose between paying 20% with indexation or 12.5% without indexation on long-term gains. This “grandfathering” lets long-time owners of houses and land still use the Cost Inflation Index to step up purchase price and cut taxable gains. For properties bought after the cut-off, indexation is largely unavailable and long-term gains default to the simplified 12.5% rate, making clear documentation of cost and improvement expenses even more critical.

Impact of Budget 2026 on long-term investors

Budget 2026 broadly continues the simplified capital gains structure introduced earlier, favouring a flat 12.5% LTCG rate with limited indexation. For equity investors, the higher exemption limit (₹1.25 lakh), a single LTCG rate, and buyback proceeds now taxed as capital gains rather than dividends together make long-term, equity-led strategies more predictable and often more tax-efficient than frequent trading or high-dividend payouts. Long-term investors in property and legacy non-equity assets should review acquisition dates and consider whether to accelerate or defer sales to optimally use remaining indexation windows versus the lower flat rate, aligning their exit plans with overall goals and cash-flow needs.

India's tax authorities have refined ITR filing timelines for FY 2025-26 (AY 2026-27) to balance efficiency and taxpayer convenience. Individuals using ITR-1 or ITR-2 (salaried, no business income) must file by 31 July 2026, while ITR-3/ITR-4 non-audit cases extend to 31 August 2026; audit cases reach 31 October 2026, with transfer pricing at 30 November. Belated returns are accepted until 31 December 2026 (with late fees under section 234F) and revised returns until 31 March 2027, offering flexibility for corrections without full updated return penalties.

Simplified ITR forms

Streamlined forms primarily aid salaried individuals, HUFs, and small taxpayers with straightforward income sources. ITR-1 (Sahaj) suits those with salary, one house, and other sources up to ₹50 lakh; ITR-2 covers capital gains and foreign assets without business income, reducing schedules for most non-business filers. Businesses and professionals use ITR-3/ITR-4 (presumptive), but simplification cuts redundant fields, easing data entry for over 70% of individual filers who avoid complex disclosures.

Increased reporting and data matching

The Annual Information Statement (AIS) now integrates deeper third-party data—bank interest, shares, property buys—from Form 26AS and TIS, enabling automatic mismatch flags. Taxpayers see AIS 15 days before filing, prompting preemptive corrections to dodge notices under faceless assessment. This compliance push, with AI-driven scrutiny, targets unreported high-value transactions, cutting evasion but raising voluntary disclosure needs to avoid penalties up to 200% on unexplained credits.

Recent tax reforms prioritise relief for small taxpayers through enhanced rebates and targeted exemptions, easing the burden on low-income earners.

Rebate under Section 87A

Under the new tax regime for AY 2026-27, individuals with total income up to ₹12 lakh qualify for a full Section 87A rebate, wiping out tax liability entirely. This rebate caps at the total tax payable, now raised from previous limits to cover incomes up to ₹12 lakh after standard deductions, benefiting salaried workers and small professionals most. Those opting for the old regime get rebate only up to ₹5 lakh income, making the new regime far more attractive for this group.

Senior citizen-specific benefits

Senior citizens (aged 60-79) enjoy a higher basic exemption of ₹3 lakh under both regimes, plus an additional ₹50,000 deduction on interest from savings accounts. Super senior citizens (80+) receive ₹5 lakh exemption without needing to file returns if income is only from pension and interest up to that limit, alongside higher TDS thresholds to reduce compliance hassle. These measures, combined with no advance tax requirement for seniors below certain income bands, provide substantial cash-flow relief.

Measures for first-time taxpayers

First-time filers gain simplified pre-filled ITRs via AIS integration and a one-time penalty waiver for minor defects in initial returns. A ₹25,000 standard deduction for new small business filers under presumptive taxation encourages formal entry into the tax net without audit fears. These steps, including extended helpline support and digital tutorials, aim to onboard young professionals and gig workers seamlessly, boosting voluntary compliance.

Budget 2026's simplified rates and higher exemptions make proactive planning essential for maximising savings while staying compliant.

Choosing the right tax regime

Salaried individuals with income below ₹12 lakh should opt for the new tax regime, where Section 87A rebate eliminates tax up to that threshold after standard deduction. Those earning ₹12-20 lakh may still prefer the old regime if they have significant deductions like ₹1.5 lakh under 80C (EPF, ELSS, insurance) or HRA exceeding the new regime's family pension relief. Businesses and professionals above presumptive limits (₹75 lakh for 44ADA) benefit from the new regime's lower slabs (30% top rate starts at ₹24 lakh) unless house property losses or high medical expenses tip the balance.moneycontrol+3

Optimising deductions legally

Max out employer NPS contributions under 80CCD(2) for up to 14% extra deduction in the new regime, alongside health insurance premiums. Time capital gains realisations to leverage ₹1.25 lakh equity LTCG exemption and grandfathered indexation for pre-2024 property sales at 12.5% vs 20%. Bundle expenses like home loan principal and tuition fees into the old regime if eligible, and use presumptive taxation for freelancers keeping cash receipts under 5%.caalley+3

Common mistakes to avoid

Don't ignore AIS mismatches—unexplained credits trigger 60-200% penalties; reconcile bank and Form 26AS data before filing. Failing to pay advance tax by 15 March (full for presumptive cases) incurs 1% monthly interest under 234B/C, eroding savings. Avoid claiming unsubstantiated expenses without invoices or mixing personal travel with business deductions, as faceless audits now flag these instantly, leading to disallowances and litigation.kissht+4

Budget 2026 builds on the Income Tax Act, 2025, effective from April 1, 2026, which simplifies rather than overhauls everything overnight.

Is the old Income Tax Act fully replaced

No, the Income Tax Act, 2025 does not fully replace the 1961 Act in practice; it repeals and consolidates it into a streamlined 536 sections from over 800, retaining core principles like income heads and residency rules. Transitional provisions ensure prior assessments, refunds, and ongoing cases continue seamlessly under the new framework, avoiding disruption for FY 2025-26 filers. Both old and new tax regimes coexist as taxpayer choices, clarifying that the "replacement" is structural, not a clean wipeout.

Do deductions completely disappear

Deductions do not vanish entirely; they are curtailed in the default new regime but fully available if you opt for the old regime via Form 10-IEA. Popular ones like 80C (₹1.5 lakh for PF, ELSS), 80D health insurance, and HRA persist in the old scheme, while the new regime offers a higher standard deduction (₹75,000) and NPS employer match instead. Perceptions of total loss stem from the new regime's design, but switching regimes keeps deductions alive for those with high claims.

Is new regime always better

The new regime suits 85% of salaried taxpayers with incomes under ₹20 lakh due to lower slabs, ₹12 lakh zero-tax via 87A rebate, and no deduction paperwork. However, it's not universally superior—those with heavy 80C/80D outflows, house rent, or business losses save more in the old regime despite higher rates. A simple calculation comparing post-deduction income against new slabs determines the winner; mid-income families with loans often find old better, urging annual reviews.

The Income Tax Act, 2025, and the reforms introduced in Budget 2026 signify a new era of tax compliance and transparency in India. By understanding the changes and planning accordingly, taxpayers can optimise their financial outcomes while ensuring compliance. Early planning, awareness of the applicable tax regime, and leveraging available deductions can help individuals navigate the new system effectively.
