Why do I have an overpayment?
The most common causes of tax overpayments and underpayments are:
Incorrectly entered tax rate; in particular, the state unemployment insurance (SUI) rate.
Paychecks added or deleted after the tax payment was approved for the payroll period.
Incorrect reconciliation of historical taxes
If an overpayment appears because of historical taxes
When you entered your prior tax payments, we noticed that you have overpaid your taxes so far this year.
If you still have at least one payroll to run in the same quarter, you don’t need to do anything.
If the quarter with the overpayment is over, you need to resolve the overpayment.
You have entered your prior tax payments, but you have not yet entered tax information from your prior paychecks. (That is, you have told us about the taxes you have paid, but you have not yet told us about the tax liabilities you have incurred. Our system thinks you have overpaid your taxes.)

QuickBooks Online automatically updates the federal tax rates. However, for state taxes, you’ll need to manually edit your State Unemployment Insurance (SUI) and State Disability Insurance (SDI) tax rates for this year (if necessary) through the Payroll Settings.
Here’s how to do it:
Click on the Gear icon.
Choose Payroll Settings.
Click on the Tax Setup tab.
Click on the name of the state.
Scroll down to the section labeled State Unemployment
Insurance (SUI) Setup. Click Change or add new rate.
Enter your new rate as a percentage from the notice you received from your state.
