Income tax in India touches virtually every earning individual, yet the system remains poorly understood by most taxpayers. With changes introduced in the Union Budget for FY 2026-27, understanding which regime applies to you, what deductions you can claim, and how to file correctly has become more important than ever. This guide walks you through every critical aspect of income tax for the current financial year so you can plan proactively rather than scramble at the last minute.
Who Needs to Pay Income Tax in FY 2026-27
Any individual, Hindu Undivided Family, firm, or company whose gross total income exceeds the basic exemption limit is liable to pay income tax. For individuals below 60 years of age under the old regime, the basic exemption limit remains at 2.5 lakh. Under the new tax regime income tax slabs, the exemption threshold has been revised upward, making it the default choice for many taxpayers. Senior citizens and super senior citizens continue to enjoy higher exemption thresholds under the old regime.
Understanding the Two Tax Regimes
India currently operates a dual-regime system. The old regime allows you to claim a wide array of deductions and exemptions under sections like 80C, 80D, and HRA, while the new regime offers lower slab rates but strips away most of those benefits. Choosing correctly between them can save you tens of thousands of rupees each year. Use the old vs new regime comparison calculator to model your exact situation before making a decision. Our detailed old vs new regime analysis breaks down the math further.
Income Tax Slabs for FY 2026-27
Under the new regime, income up to 3 lakh is exempt from tax. The next slab from 3 lakh to 7 lakh attracts 5 percent, 7 to 10 lakh attracts 10 percent, 10 to 12 lakh attracts 15 percent, 12 to 15 lakh attracts 20 percent, and income above 15 lakh is taxed at 30 percent. A standard deduction of 75,000 is available under the new regime. Surcharge and cess apply on top of these base rates. The old regime retains the familiar structure of 0, 5, 20, and 30 percent slabs, but the real advantage lies in the deductions you can stack. To calculate your exact liability under both systems, try the income tax calculator for the new regime.
Key Deductions and Exemptions Under the Old Regime
The old regime remains attractive for taxpayers who have significant investments and expenses that qualify for deductions. Section 80C alone allows up to 1.5 lakh in deductions across ELSS, PPF, EPF contributions, life insurance premiums, NSC, and tuition fees. Beyond 80C, you can claim deductions under 80D for health insurance premiums, 80E for education loan interest, 80G for charitable donations, and several others. House rent allowance, leave travel allowance, and standard deduction further reduce your taxable income. Explore the full list in our Section 80C tax saving guide.
How to Compute Your Total Tax Liability
Start with your gross salary or gross total income from all sources -- salary, house property, capital gains, business income, and other sources. Subtract eligible exemptions such as HRA and LTA. From the resulting gross total income, subtract deductions under Chapter VI-A. Apply the applicable slab rates to the remaining taxable income. Add surcharge if your income exceeds 50 lakh, and then add 4 percent health and education cess on the total tax plus surcharge. If you have income from equity or debt investments, check the capital gains tax calculator separately, as these are taxed at special rates outside the slab structure.
TDS, Advance Tax, and Self-Assessment Tax
Most salaried individuals have tax deducted at source by their employer. However, if you have income from freelancing, rent, capital gains, or interest that is not subject to adequate TDS, you may need to pay advance tax in quarterly instalments. Missing advance tax deadlines attracts interest under sections 234B and 234C. Use the advance tax calculator to determine your quarterly obligations and avoid penalties.
Filing Your Income Tax Return
Every individual whose gross income exceeds the basic exemption limit, or who wants to claim a refund, must file an ITR. The due date for salaried individuals and those not requiring audit is 31 July. Choosing the correct ITR form -- ITR-1 for simple salary income, ITR-2 for capital gains, ITR-3 for business income -- is the first step. Our step-by-step ITR filing guide covers form selection, document preparation, common mistakes to avoid, and post-filing verification.
Common Mistakes to Avoid
The most frequent errors include not reconciling Form 26AS with claimed TDS, forgetting to report interest income from savings accounts and fixed deposits, ignoring advance tax obligations on capital gains, selecting the wrong ITR form, and missing the verification deadline after filing. Each of these can result in notices, penalties, or delayed refunds. Taking thirty minutes to cross-check your data before submission can save you months of correspondence with the tax department.
Planning Ahead for FY 2026-27
Tax planning is most effective when done at the start of the financial year, not in March. Declare your preferred regime to your employer early so TDS is deducted correctly. Spread your 80C investments across the year through SIPs into ELSS or monthly PPF contributions. Review your salary structure with HR to optimise components like HRA, NPS employer contribution, and meal vouchers. A well-planned approach ensures you pay only what you legitimately owe and retain the maximum portion of your hard-earned income.
