What Is GST Registration?

GST Registration is the process through which businesses get a unique Goods and Services Tax Identification Number (GSTIN). This 15-digit GSTIN allows you to legally collect GST from customers and claim input tax credit on your purchases.

Every eligible business in Karnataka must obtain GST registration to comply with national tax laws and avoid penalties.
