Built with the Latest Data for FY 2025-26

Every time the Union Budget announces new slabs, or the GST Council revises rates, we update our calculators right away. The new income tax regime slabs with the Rs 12 lakh rebate, updated TDS thresholds, and current GST rate schedules are all reflected. You are always working with accurate, current numbers.

Your Data Stays in Your Browser

All calculations run entirely in your browser using JavaScript. Nothing gets sent to any server, and we do not store your financial information. The only thing saved is your last input in local storage for your convenience.

Made Specifically for Indian Tax Laws

These tools are not generic international calculators adapted for India. Every formula, slab, and edge case follows Indian tax law precisely. Amounts display in the Indian numbering system (lakhs and crores), GST splits correctly into CGST and SGST for intra-state transactions, and Section 87A rebate with marginal relief is calculated exactly as the Income Tax Department prescribes.
