Narrative:

We were on approach VOR 09L (bow) and in communication with bow tower. The tower cleared us for the circle to land to runway 5 and instructed us to report when we commenced our circle. We completed our circle to land and landed without incident on runway 5. While rolling out on runway 5; we asked the tower for taxi instructions to [runway] 09L where we wanted to completed touch-and-goes. The tower responded that we had not reported our circle-to-land and had not received a landing clearance for runway 5. I believe the problem was caused by proficiency and task saturation. I have not flown in this aircraft since late [date removed]; flown approximately 5 hours total since that time; not completed a circle-to-land in a long time and not operated in bow before. In terms of task saturation; I was flying with a newer copilot and had a brand new copilot observing from the cabin. Lastly; fatigue played an issue as we were two hours into our training flight and had already completed an approach to holding pattern; air maneuvers and then an approach into bow.
