Maximum combined deduction (salaried, without HRA): Std ₹50K + 80C ₹1.5L + NPS ₹50K + 80D ₹75K + Sec 24b ₹2L = ₹5,25,000. With HRA, can exceed ₹7–8 lakhs.

Frequently Asked Questions – Income Tax India 2026-27
What are the income tax slabs for FY 2026-27 under New Tax Regime? +
Under New Regime FY 2026-27: Up to ₹4L — Nil; ₹4–8L — 5%; ₹8–12L — 10%; ₹12–16L — 15%; ₹16–20L — 20%; ₹20–24L — 25%; Above ₹24L — 30%. Salaried individuals get ₹75,000 standard deduction. Section 87A rebate of ₹60,000 makes effective tax zero for taxable income up to ₹12 lakh — so gross salary up to ₹12,75,000 = zero tax.
Is income up to ₹12 lakh tax free in FY 2026-27? +
Yes — but only under the New Tax Regime. Section 87A rebate of ₹60,000 is available for taxable income up to ₹12,00,000. For salaried individuals with ₹75,000 standard deduction, gross income up to ₹12,75,000 results in zero tax. Important: if income exceeds ₹12,75,000 by even ₹1, the rebate is lost entirely (cliff effect) — full tax applies on ₹12,01,000 taxable income.
What is surcharge on income tax and who pays it? +
Surcharge is an additional levy on income tax (not on income) for high earners: 10% for income ₹50L–₹1Cr; 15% for ₹1–2Cr; 25% for ₹2–5Cr; 37% for above ₹5Cr (capped at 25% under New Regime for most income types). Health and Education Cess of 4% applies on (tax + surcharge). This calculator computes surcharge for income up to ₹1 crore automatically.
Can I switch between New and Old Tax Regime every year? +
Salaried individuals can switch every year — declare your choice to your employer at the start of the financial year or change it at the time of ITR filing. Business owners have limited flexibility — once they opt out of the New Regime, they can return to it only once. Salaried employees often make a different declaration to employer vs ITR — ITR filing choice is the final one.
What is the ITR filing deadline for FY 2026-27? +
The standard ITR filing deadline for FY 2026-27 (AY 2027-28) is July 31, 2027 for most individuals (salaried, freelancers, individuals not requiring audit). For businesses requiring tax audit, the deadline is October 31, 2027. Belated returns can be filed until December 31, 2027 with a late fee of ₹5,000 (₹1,000 if income below ₹5 lakh). Filing after the deadline also means losses cannot be carried forward.
How is HRA exemption calculated? +
HRA exemption (Old Regime only) is the minimum of three values: (1) Actual HRA received; (2) Actual rent paid minus 10% of Basic Salary + DA; (3) 50% of Basic + DA if metro city or 40% for non-metro. Example: Basic ₹40,000/month, HRA ₹20,000/month, rent paid ₹18,000/month in Mumbai. (1) ₹20,000; (2) ₹18,000 – ₹4,000 = ₹14,000; (3) 50% of ₹40,000 = ₹20,000. Minimum = ₹14,000/month = ₹1,68,000/year is exempt.
