GST Late Fee.com
Our Mission & Purpose

About gstlatefee.com

Building the fastest, most reliable, and accessible GST compliance calculation platform for Indian businesses, tax professionals, and Chartered Accountants.

Why We Created gstlatefee.com

Navigating the Goods and Services Tax (GST) framework in India can be daunting. With over a crore registered taxpayers, periodic changes in CBIC notifications, staggered state deadlines under QRMP, and evolving caps under Notification No. 20/2021 and 07/2023, calculating penalties manually often leads to errors, portal notices, or overpayment.

Existing online calculators were clunky, covered only a single month at a time, forced manual page reloads, and crucially failed to calculate Section 50 interest on cash tax liability. We built gstlatefee.com to solve these exact frustrations by providing a clean, developer-grade, 100% free tool that delivers instant, legally verified calculations.

  • Notification No. 20/2021–Central Tax: Turnover-based capping thresholds (₹2,000, ₹5,000, and ₹10,000 caps).
  • Notification No. 07/2023–Central Tax: Tiered per-day rates and turnover-based percentage ceilings for GSTR-9 annual returns.
