Free Income Tax Calculator – India FY 2026-27 (New vs Old Regime) & US Federal Tax
The NexVaani Income Tax Calculator provides taxpayers in India and the United States with an accurate, up-to-date assessment of their annual tax liability and monthly take-home salary. For Indian taxpayers under FY 2026-27 (AY 2027-28), choosing between the New Tax Regime (with its enhanced ₹75,000 standard deduction and lower tax slabs) and the Old Tax Regime (allowing Section 80C, 80D, and HRA deductions) is complex. NexVaani computes both regimes simultaneously, highlights your exact tax savings, and recommends the superior regime. For US filers, the calculator estimates Federal income tax and effective rates across Single and Married Filing Jointly brackets.

Technical Architecture & Execution Mechanics
Progressive Marginal Slabs & Section 87A Marginal Relief
Income tax utilizes progressive marginal tax brackets. Under India's New Regime, tax is partitioned: 0% up to ₹3L, 5% on ₹3L-₹7L, 10% on ₹7L-₹10L, 15% on ₹10L-₹12L, 20% on ₹12L-₹15L, and 30% above ₹15L. Section 87A provides a full tax rebate if taxable income does not exceed ₹7,00,000, capped with a 4% Health & Education Cess.
Tax = \sum (\text{Bracket}_i \times \text{Rate}_i); Total = (Tax - \text{Rebate}_{87A}) \times 1.04Technical Limitations & Operational Constraints
- State-specific income taxes in the US and specialized capital gains surcharges should be evaluated with a qualified CPA or Chartered Accountant.
