ABOUT MERIGST

Simplifying Indirect Taxation for Indian Businesses & Professionals

MeriGST is a fast, modern, and completely free indirect tax calculation suite designed specifically for Indian micro, small, and medium enterprises (MSMEs), freelance professionals, traders, and tax practitioners.

Our Mission

Navigating the Goods and Services Tax (GST) in India can often be complicated by multiple statutory slabs (0%, 5%, 12%, 18%, 28%), dual-taxation splits (CGST & SGST for intra-state vs. IGST for inter-state), reverse tax calculations from MRP, and complex Input Tax Credit (ITC) utilization rules under GSTR-3B.

Our mission is to eliminate tax confusion and manual math errors by providing an instant, clean, zero-bloat financial computational tool that gives you accurate numbers in real time—without subscriptions, registration barriers, or intrusive advertisements.
