In this paper, we study the algebraic structure of differential invariants of a fifth-order KdV equation, known as Kawaha KdV equation. Using the moving frames method, we locate a finite generating set of differential invariants, recurrence relations, and syzygies among the differential invariants generators of the equations. We prove that the differential invariant algebra of the equation can be generated by two first-order differential invariants.
