How can i change gst number which was newly issued to my company

Hello,

Welcome to QuickBooks Community!

Here are the steps to follow:

GST for QuickBooks companies that have set up tax agencies

1. Existing companies that have set up tax agencies will see the “GST ready” widget on the dashboard page.
2. Enter your GSTIN (Not having GSTIN won’t stop you from creating invoices using GST tax rates in QuickBooks) and click Save.

GST for QuickBooks companies without taxes setup

Companies (existing and new) which have not enabled tax will see a Setup GST widget on the dashboard page

1. Click Setup GST
2. The Edit GST settings popup will appear
3. Enter Start of the tax period, which would be July 1st, 2017
4. Enter your GSTIN
5. Choose your Filing frequency and Accounting method
6. Click Save
