New Company - short plan year

A one-man company, inception date 12/1/2018, would like to start a 401k with an initial short plan year, 12/1/2018 to 12/31/2018. 

If the Limitation Year is defined as the calendar year, is it permitted to not prorate 415 and comp, even though the company has only been in existence for 1 month?

Thank you very much.

Yes.  This language is actually included in many prototypes.

Good Luck!

Thank you very much for the confirmation.
