Welcome to the Community. Changing your PST number is necessary sometimes and I'll be happy to show you how to easily do that in QuickBooks. Here's how:
Go to the Taxes tab on the left.
On the Sales Tax page, click Manage sales tax.
Select the pencil icon beside the name of the sales tax agency in question.
Edit the number entered in the sales tax number field.
Click Save.
Give this a try and if you have further questions, I recommend contacting our support team using this link.
