Frequently Asked Questions
Which regime is better: New or Old Tax Regime?
For most salaried taxpayers with total deductions under ₹3.75 lakh, the New Tax Regime typically results in lower tax due to wider slabs and lower rates. If you have substantial HRA, home loan interest, and 80C/80D deductions, the Old Regime may remain beneficial.
What is the standard deduction for salaried individuals in AY 2026-27?
Under the New Tax Regime, the standard deduction for salaried employees is ₹75,000. Under the Old Tax Regime, the standard deduction is ₹50,000.
How does the Section 87A rebate work under the New Regime?
Under the New Tax Regime, resident individuals with taxable income up to ₹7,00,000 (after standard deduction) are eligible for a full tax rebate under Section 87A, resulting in zero net tax liability.
