The Problem

TDS is manual,
error-prone, and risky

Finance teams across India spend hours every month calculating TDS manually — referencing outdated charts, missing threshold checks, and risking penalties for wrong deductions.

  • 📊
    Excel errors cost real money. Wrong threshold checks lead to under or over-deduction — both attract IT department scrutiny.
  • ⏰
    Act 2025 changed everything. New section numbers, updated thresholds, restructured provisions — most software hasn't caught up yet.
  • 📋
    No audit trail means no defence. When disputes arise, you need to prove exactly which rate was applied and why.
