I need to unschedule a tax payment that I confirmed by mistake.

Thank you for posting here on the Community, pageaubreywallace and Kyle69.

I can share with you the steps on how to delete tax payment in QuickBooks Online. 

You can cancel and delete an electronic Federal tax payment two business days before the payment date. States might take up to five business days since they have a different lead-time for processing tax payments. 

Here's how: 

1. Go to the Taxes menu and then select Payroll tax.
2. Under Taxes, select View tax payments you've paid.
3. Choose a date range and then the name of the tax payment.
4. From the drop-down menu, select Delete.
5. To confirm, click Yes.

However, if the payments were already processed electronically, I'd recommend contacting our Payroll Support Team. This way, they can help you cancel the tax payment. 

Here's how to reach them:

1. Click the Help menu in the upper-right-hand corner.
2. Type in "Talk to a human", then press Enter.
3. Look for I still need a human and click on it.
4. Click Get help from a human or Contact Support Team.
5. Select between Send a message, Schedule an appointment, or Get a callback.

Please check out our support hours to ensure that we address your concerns on time.
