[Back](./) # How do I apply SGST, CGST & IGST to my transactions? According to GST norms, you must apply SGST and CGST together on the intra-state transactions of goods and services while IGST must be applied on the inter-state transactions of goods and services. If you’ve configured the GST Settings in Zoho Billing, the individual taxes such as SGST and CGST with standard rates and tax groups based on GST rate slabs will also be auto-populated. When you create intra-state transactions in Zoho Billing, you can select the appropriate group tax to apply to the transaction. To apply **IGST** on inter-state transactions of goods and services, you can select the appropriate auto-populated tax.
