He's HCE for 2016. The only place you'd need to look for that is the definition of HCE in your plan document. Obviously, 414(q) is the statutory definition, but the plan's language will align with that (plus will specify whether or not the sponsor is actually using the top paid group election). For 2016, he can be an otherwise excludable HCE for testing purposes. He's going to be an HCE either way. I'm not sure about what road block you are running into because of his HCE status. Usually, and HCE who gets zero helps the test. Good Luck!
