Wax then Tan. If you do it the other way then your tan won't be smooth across your body because the hair partially blocked the light.

If you wax and then tan just know that area you waxed will be very very sensitive to the UV Lights. So there is a chance of sunburn there slightly. If you go in gradual sessions you should be okay however.
I recommenced wax and then tan.
