I am having a difficult time trying to figure out how the labor cost is being calculated on the 6-1-2, labor cost reports. they are varying highly for my designer. the same job had one days work at 31.80$ and another days at 75.20$, regular hours, not overtime. I am wondering if it is calculating the labor cost based on the paycheck that the weeks time was on. In other words on week of 12/11 she had $0 commission so her taxable burden was lower than week 12/18 where she received a considerable amount of commission raising her taxable burden higher. Any insight would be helpful.
