Income Tax Act 2025: 7 Big Changes That Will Affect Your Tax Liability — Buyback, Dividend & Salary
From April 1, 2026, India's 65-year-old tax law is officially retired. The Income Tax Act 1961 has been replaced by the new Income Tax Act 2025 — and if you're a salaried employee, investor, or small business owner, some of these changes will directly hit your wallet.
Here's what actually changed, and what it means for you.
The structural overhaul is significant. Sections have been cut from 819 to 536, chapters from 47 to just 23, rules from 511 to 333, and forms from 390 to 190. The government's stated goal: less confusion, lower compliance burden, and a tax filing process that doesn't require a specialist every single time.
One important clarification before we get into the changes: income earned up to March 31, 2026 is still assessed under the old 1961 Act. Income from April 1, 2026 onwards falls under the new law. Any pending assessments, appeals, or proceedings that were already underway will continue to be handled under the old rules.
Tax expert CA (Dr.) Suresh Surana notes that ITA 2025, along with the Income Tax Rules 2026 and new ITR forms, has been effective from April 1, 2026. He describes these changes as a significant reform in India's direct tax system, aimed at simplifying and restructuring how tax is assessed and filed.
While the government has positioned this as a continuity measure — maintaining existing tax policy rather than overhauling it — several provisions do create real shifts in liability for different categories of taxpayers. Some processes have become genuinely easier. In other cases, the tax burden has actually increased.
His overall assessment: the cumulative intent is to reduce confusion and simplify the system, but the practical effects vary by taxpayer profile. Every individual needs to understand how these specific changes apply to their own income situation.
Here are the seven most important changes under the new income tax law.
The most foundational shift is the elimination of the "previous year" and "assessment year" dual-calendar system. Under ITA 2025, both concepts are merged into a single "Tax Year."
This might sound like a technical housekeeping change, but it's been a genuine source of confusion for ordinary taxpayers for decades — particularly when filing returns, calculating advance tax, or dealing with any assessment-related correspondence. A single tax year reference simplifies all of that in one move.
Under the Income Tax Rules 2026, the scope of simplified return filing has been widened. Taxpayers who own up to two residential properties can now file ITR-1 or ITR-4 — previously, ownership of a second home automatically disqualified you from these simpler forms.
The revised return deadline has also been extended to March 31 of the relevant tax year. This gives taxpayers considerably more time to catch and correct errors in their original filing, which should reduce the volume of defective return notices the department processes annually.
From April 1, 2026, the method of taxing share buybacks has fundamentally changed. Under the old rules, the entire buyback amount received by a shareholder was treated as deemed dividend and taxed accordingly. That was a broad and often heavy-handed approach.
Under ITA 2025, only the actual profit — buyback price minus the original acquisition cost — is taxable. This aligns buyback taxation more closely with capital gains logic.
There's a catch for a specific group: in certain cases involving promoter shareholders, an additional 12% surcharge applies on top of the normal tax rate. If you're a retail investor, this change is broadly favourable. If you're on the promoter side, factor in the surcharge before assuming this is a clean win.
The valuation rules for perquisites — employer-provided benefits such as company cars, accommodation, and other non-cash compensation — have been revised under Income Tax Rules 2026. Both the valuation methodology and the applicable limits have changed.
In practical terms, the taxable value of certain perquisites has gone up, which means employees who receive these benefits could see a higher tax liability on paper, even if their cash salary hasn't changed. Car-related perquisites appear to be among the categories most affected by the revised valuation norms.
Several tax-free allowances and exemption thresholds have been raised under the new rules. The updated limits cover employee loans, meal allowances, gift exemptions, children's education allowance, hostel allowance, and HRA — with the HRA expansion now recognising more cities as metro centres for the purpose of calculating the higher exemption.
This is one of the genuinely positive changes for salaried employees, particularly those in tier-2 cities that were previously excluded from the higher HRA calculation.
Section 395 of ITA 2025 expands the scope of the Lower Deduction Certificate mechanism. Any taxpayer whose income is subject to TDS can now apply for a certificate allowing tax to be deducted at a reduced rate — or not at all — based on their estimated annual income and projected tax liability.
This is particularly useful for freelancers, consultants, and business owners who regularly receive income after TDS deduction and then wait for refunds. The expanded eligibility under Section 395 brings more people into the LDC framework than were covered before.
Under the previous rules, investors could claim a deduction for interest expenses up to 20% of their dividend income — a meaningful offset for anyone who had borrowed to invest in dividend-paying stocks or mutual funds.
That deduction no longer exists under ITA 2025.
Section 93(2) of the new law removes all deductions for interest expenses incurred to earn dividend income or income from mutual fund units. The result: the taxable income under "Income from Other Sources" rises for anyone in this position. Investors who used debt to build their dividend portfolios will feel this most sharply — their effective tax cost on the same income is now higher than before.

Under ITA 2025, only your actual gain on the buyback gets taxed — not the entire amount you receive. So if a company buys back shares at ₹200 that you originally purchased at ₹80, only the ₹120 profit is taxable. Before April 1, 2026, the old system taxed the full buyback amount as deemed dividend, which was a heavier hit. One thing to watch: in certain cases involving promoter shareholders, an additional 12% surcharge applies on top of the regular tax. If you're a retail investor, this change is largely in your favour.
Yes, you can — that's one of the clearest wins in the new income tax rules. Earlier, owning even a second house automatically pushed you out of ITR-1 and ITR-4, forcing you to file a more complex return. From FY 2027 onwards, taxpayers with up to two residential properties can still use ITR-1 or ITR-4, provided their other income conditions are met. This directly reduces the compliance burden for millions of middle-class property owners. Practical tip: double-check whether your second property generates rental income — that income still needs to be reported accurately even within the simplified form.
It's gone. Under Section 93(2) of ITA 2025, you can no longer claim a deduction for interest expenses incurred to earn dividend income or income from mutual fund units. Earlier, up to 20% of the dividend income could be offset by interest paid on loans taken to fund the investment. If you've borrowed money to build a dividend-generating portfolio, your taxable income under "Income from Other Sources" will now be higher than before. Honestly, there's no workaround here other than reconsidering how you fund equity investments going forward.
Under Section 395 of ITA 2025, any taxpayer whose income is subject to TDS can apply for a certificate to have tax deducted at a lower rate — or even at nil — based on projected income and estimated tax liability for the year. You file the application with your Assessing Officer, who then issues the certificate if your case qualifies. This is especially useful for freelancers, consultants, and small business owners who often get excess TDS deducted throughout the year and then wait months for a refund. Practical tip: file your LDC application early in the financial year — ideally in April itself — so you don't lose the benefit for the first few months.
The revised return deadline has been extended to March 31 of the relevant tax year, giving taxpayers significantly more time to correct mistakes. Under the old system, the window was tighter and caught a lot of people off guard. So if you filed your return for Tax Year 2026–27 and spotted an error later, you now have until March 31, 2027 to fix it. This one change alone should reduce the number of defective return notices the department issues every year — don't wait until the last minute, though, as processing delays do happen.
The bottom line: ITA 2025 simplifies the structure of tax law significantly, but simplification doesn't automatically mean lower taxes. The removal of the dividend interest deduction and the revised perquisite valuations add real cost for specific taxpayer groups. If your income involves leveraged investments, company-provided benefits, or share buybacks, it's worth sitting down with a CA before the first advance tax instalment is due for FY 2027.
