You can use the reports in sales tax and the sales tax module to figure it out what is due, but you are correct, you cannot reconcile it (if you are using the default acct. that is the sales tax detail type). She can run a trial balance. Look at that acct. and see the balance at the end of the month and verify it with the payment amount. I like to lock out the month with a password, especially if there are several users with access to the customer transactions. That way once sales tax is paid, no one can make changes to the closed period (without the password).
