I tried paying a tax payment and it said it was processing and then timed out and said to check later. How do I know if it went through?

Welcome to the Community, @yayladybugs.

To confirm if your tax payment went through after a timeout, all you need to do is check the payment status in QuickBooks Self-Employed (QBSE) and your bank account. Simply go to the Taxes section in QBSE and be sure to use a supported web browser for optimal performance.

Alternatively, you can check your email for a confirmation once your payment has been successfully processed.
