Goods and Services Tax (GST) has become the backbone of India’s indirect tax system. Every business owner who crosses the turnover threshold—or falls under mandatory registration rules—must complete the GST registration process. Having a valid GSTIN (Goods and Services Tax Identification Number) not only ensures compliance but also builds credibility and helps businesses expand without restrictions.
In this blog, we’ll explain the entire GST registration process in India (2025), including eligibility, documents required, step-by-step application, fees, and key mistakes to avoid.
