Quick Summary: Second Income Tax Impact Calculator
The Second Income Tax Impact Calculator measures the 'Marginal Tax Shock' of adding extra income to your base salary. In FY 2026-27, since your base income already exhausts the lower tax slabs, every rupee of your side-hustle income is usually taxed at your highest marginal rate (e.g., 30%), significantly impacting your actual take-home profit.
