Hello Paul204,
Thanks for being a member of the QuickBooks Self-Employed family for two years! I appreciate your dedication to the product, and it sounds like apart from this recent issue with sales tax, it's been working well for you. Don't worry, I can point you in the right direction to ensure this is resolved and your invoices are sent to your customers with the correct amounts, including tax.
Since you're working with the mobile application, the first troubleshooting step I recommend is uninstalling and reinstalling the app. Doing this makes sure the app is up to date and that its cache is free of any data that may cause glitches like you're seeing. Once you've done that, I recommend creating a test invoice to send to yourself that you can delete later to see if the sales tax is showing correctly when you receive the emailed form. Our Create invoices in QuickBooks Self-Employed article goes into detail about working with invoices.
In the event you're still seeing the issue with emailed invoices not including the sales tax, please reach out to our QuickBooks Self-Employed team outside of the QuickBooks Community forum to troubleshoot further and learn what steps we can take to resolve this. Here's how you can connect with that team.
- Select the Assistant feature.
- Type and enter "talk to human."
- Follow the prompts.
Wishing you the best with this!
