I am making an invoice on my mobile device, and the sales tax for items on the invoice is not being added. What am I missing to add simple sales tax to my invoices?

Let’s perform some troubleshooting steps to find out why sales tax isn't appearing on your invoices in the QuickBooks Online mobile app, Gemma.

Doing so eliminates outdated app components that interrupt the system's performance.

For iPhone devices:

1. Navigate to your device's Settings.
2. Select General and click iPhone Storage.
3. Locate and select the QBO app from the list.
4. Tap Offload App. This removes temporary app data and refreshes the app while retaining its essential information.
5. Reinstall the QBO app by going to the App Store and downloading it again.

For Android devices:

1. Open your device's Settings.
2. Select Applications or App Manager.
3. Locate and click the  QuickBooks Online (QBO) app from the list.
4. Tap on Storage, then choose Clear Data.

If the issue persists after clearing the app data, try updating the app to the latest version from the Google Play Store or App Store.

You can also consider uninstalling and reinstalling the app if the problem continues, or logging into your account using a web browser.
