How do I change my gst number on my invoices?

Hi autohavenppf-gma.

I know how important it is to have the correct tax information on your sales transactions in QuickBooks. With this, I can go through the steps to help you out updating your GST number.

1. Go to the Taxes menu, then click the Manage Sales Tax button.
   
2. Under Tax agencies, click on Edit agency settings.
   
3. Update your GST/HST number there.
4. Once done, click on Save.

I'm leaving a few related links about sales tax processing for additional reference:

• Set up and use sales tax in QuickBooks Online

• Use sales tax on an invoice or sales receipt

Post here anytime if you have other questions or concerns about sales tax or anything about QuickBooks. I'll be right here to help you out. Have a good one!
