GST Registration
GST Registration made easy with CASYST expert assistance.
GST registration gives your business a GSTIN, the tax identity you need to collect GST, claim input tax credit and sell across states and on online platforms. CASYST handles the application from documents to GSTIN so you can start trading compliantly.
What is GST Registration?
Goods and Services Tax (GST) is the indirect tax levied on the supply of goods and services in India. Businesses whose turnover crosses the prescribed threshold, and certain categories of businesses regardless of turnover, must register and obtain a 15-digit Goods and Services Tax Identification Number (GSTIN).
Thresholds and rules differ for goods and services, special category states and e-commerce sellers, and they are revised from time to time. We confirm what applies to you before we file.
Who needs GST Registration?
- Businesses whose turnover exceeds the registration threshold
- E-commerce sellers on online marketplaces
- Businesses making taxable supplies to other states where registration is required
- Businesses that want to claim input tax credit
- Casual taxable persons and non-resident suppliers
