Narrative:

ATC cleared us to fly a visual approach to runway 36R at tpa and to turn over macdill air force base and maintain 2;600 ft until north of macdill. I turned abeam the northern edge of macdill; cut across the corner of the field boundary; continued the turn to a more northerly direction; and descended below 2;600 ft. ATC said we were too low over macdill and we said we were north of macdill runway 4; but still over the field boundary. Then ATC said we were actually 3/4 mile north of macdill and that we didn't turn over macdill. We said we did; but always stayed north of the runway. He canceled the clearance and had us climb back to 2;600 ft and turned us back to a 270 heading for a few moments before re-clearing us for a visual approach. That clearance he gave has always; in the past; meant to stay at 2;600 ft until south of the runways which we did. We felt we had complied with his instructions since there wasn't a definite point over macdill given. I suppose he wanted us to fly further south before turning in to the runway and descending; but if we had; I would still have descended where I did at the north field boundary.

Title: Air Carrier on visual approach to TPA was questioned by ATC regarding apparent no compliance with altitude crossing restrictions over MacDill AFB.
