3% Nonelective SH with QACA

I'm new to 401K's and was hoping to get some confirmation or correction on a plan design.

I understand that the 3% SH nonelective contribution must be immediately 100% vested. My question is, if the plan also has a QACA does that remove the 100% immediate vesting requirement and change it to a 2 year cliff requirement?

Thank you for any guidance.

If elected in the AA, the QACA SH (match or nonelective) can have a vesting schedule attached. 

Thank you Bill! It would seem that with the new requirement from Secure that new plans have an ACA, many new 401Ks might as well use a QACA to avoid the 100% vesting on the 3% nonelective contribution.

Maybe. I think it depends on the eligibility requirement. If you use 21/1 with semi annual entry, most people will have two years of service before entering the plan.
