Calculate the real tax impact of adding a second income or side hustle to your salaried job. Identify your highest marginal tax slab.
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.
