I agree, dso0216, that there should be a better way of notifying the clients about rejected payments. I also strongly believe that there should be some kind of reminder within QBDT that it's time to change the password for EFTPS. This is the second year that I've dealt with this issue, and I still haven't seen anything within the program that tells us that this is necessary. I only happened across a post in one of these threads from another user (not even a QuickBooks employee) which told me that this was a requirement for third-party payroll solutions when working with EFTPS. As much as we all pay for these subscriptions, this particular issue should be handled a lot differently; we should have better information from QB about this.
