GST Registration Process

What Is GST Registration & Why It Matters

GST (Goods and Services Tax) Registration is the process by which a business is enrolled under the Goods and Services Tax law, obtaining a unique 15-digit GSTIN (GST Identification Number).

Once a business crosses the prescribed turnover threshold, or falls under certain mandatory categories, GST registration becomes compulsory — operating without it can attract heavy penalties, and registered businesses also gain the right to claim Input Tax Credit on purchases.

TrustMark IP Consultants manages the complete journey — document preparation, application filing on the GST portal, ARN tracking, and GSTIN allotment — so your business stays fully compliant from day one.
