According to staffer in CUNY Human Resources, there is no W2 data regarding NYC local income tax because of a software policy or error that refuses to include the data on the CUNY W2. My experience in April 2018, during which I spent over 8 hours trying to master the issue, with 2 EAs and 1 very helpful CPA with whom I toiled for over 5 hours. Imagine having to pay a CPA for that. But then I may go that route for 2018 taxes.
