Why am I getting an error message when creating an expense. It says validation failed, QuickBooks encountered error while calculating tax.

I appreciate you bringing this matter to our attention, calderaflower. Let's take some troubleshooting steps to ensure you can create an expense.

We've been getting similar reports from customers encountering an error message on iOS saying, "Validation failed. We're sorry, QuickBooks encountered an error while calculating tax. Try reselecting the tax rate or reentering the product/service item and saving the form again."

If you're using iOS, ensure that your app is updated. Once verified, we need to refresh or clear your app's data. This process will help eliminate any issues caused by outdated or corrupted data, ensuring the program runs smoothly.

To clear your app data using IOS, please follow these steps:

1. Open your iPad settings.
2. Click General, then Select iPhone Storage.
3. Choose QuickBooks from the list of applications.
4. Hit Offload App to free up its storage without removing the documents and data for the app.

If you're using the Android mobile app, ensure it's updated. Then, here's how you can clear your app data:

1. Open your phone's settings. Click Apps.
2. Select the QuickBooks app from the list.
3. Hit Storage, then tap the Clear Data button.

If the issue persists, uninstall and reinstall the application to start afresh.

In the meantime, you can consider uploading your receipts and creating an expense using your web browser to help you move forward.

For future use, you can conveniently use your mobile device to take pictures of your receipts and then upload them for record-keeping and tracking purposes.

Now, you can actively work on your tasks after following the troubleshooting steps and workaround provided. Feel free to add follow-up questions below. I'm still here to help, calderaflower.
