Sales tax payments in QuickBooks Online have special properties that make them difficult to reconcile from the account register.
If you need to re-reconcile a tax payment you have deleted and recreated, follow these steps:
Select the Gear icon on the Toolbar.
Under Tools, select Reconcile.
Select the bank account from which you made the sales tax payment from the Account drop-down list.
Make a note of the Statement Ending Date and Ending Balance for the most recent reconciliation.
Select Start Reconciling and enter the same statement ending date and ending balance
Select only the sales tax payment you need to reconcile.
Select Finish Now.
A second Reconcile report is generated for the month, representing the single reconciliation you performed for the sales tax payment. You should now be able to reconcile your next statement.
Note: If the ending balance does not match and QuickBooks Online suggests making an adjustment, there are likely other transactions that have been changed. We recommend postponing reconciling the sales tax payment until the other transactions have been resolved.
