TN Staff Tax Calculator

TN Staff Tax Calculator is a standalone offline calculator designed for Tamil Nadu government employees and teachers to estimate Income Tax for the Financial Year 2025-26 (Assessment Year 2026-27). It is not a government app, and it stores all data locally on your device.

Key features include up-to-date tax rules for FY 2025-26, automated calculations (DA and HRA auto-calculated from Pay Level and Basic Pay), support for deductions (CPS, GPF, SPF, FBF, NHIS), customizable allowances, a detailed tax breakdown, PDF statements, and multi-profile support. The app works offline and emphasizes privacy, with no data sent off-device.
