As of March 2017 the North Carolina PTA is using MemberHub for all local PTA units to submit their Financial Review Confirmations.
If you are a Site Administrator for your PTA MemberHub site you will see a tab in the Admin Console labeled PTA. Clicking on that tab gives you access to various pages to perform PTA-specifc duties that keep your unit in good standing.
After clicking the PTA tab, then click Form 990s on the right. You will then see the previous Form 990 confirmations.
Simply click the Add a New Form 990 Confirmation button on the left under that list. The resulting popup window will allow you to complete the form and post the new confirmation.
The just click the Submit Confirmation button on the bottom of the popup dialog.
You're all set! This data will automatically sync with the NCPTA database ;-).
