Thanks for reaching out to us, @deepti3.
I'm here to help you understand when and why QuickBooks displays GST or IGST rates when creating invoices and sales receipts.
To begin, if a GSTIN is not specified in Tax Settings, QuickBooks will assume that the transactions are intrastate and will simply display GST rates.
When creating an invoice in QuickBooks Online, you can select a Place of Supply. This is the location where the goods are delivered and are used to determine whether the transaction is inter-state or intra-state.
Furthermore, QuickBooks determines whether a transaction is Intrastate (within the same state) or Interstate (between two states) and displays GST or IGST rates accordingly. Please refer to this article for your reference: How do I apply IGST on my invoices?
Aside from your business location, the Place of Supply and the GST registration type are the factors to consider when determining which rate type you will see in transactions. You must ensure that they are properly configured. Please read the following articles to learn more about managing your GST and IGST in QuickBooks Online: Know more about GST registration types for customers in QuickBooks.
If you have any further questions about taxes, please respond here. Let me know if you have any other questions, such as how to record a specific transaction or run a specific report. I'm here to assist you.
