Not to question the above comments because you guys probably know a lot more about this than I do, but I always carried a printed taxi rates chart by zone in the past. I think there was something like 16 or 20 zones that showed fixed rates based on where you were and where you were going. If you took a taxi from Philipsburg to Simpson Bay I would check out the chart and if it said $20, then the taxi we would call (or have called for us) would charge that amount. My experience was that these rates were remarkably consistent and only changed if you shared a taxi with another couple or a group of people. Did something change recently reading this? We always took the authorized taxi's from what I recall, and the drivers wore orange shirts. If the taxi rates have jumped I may just rent a car again.
