Two different rates matter here, and they are easy to confuse. The effective rate of 3.0% is the average cost of every unit of pay across the whole salary. The marginal rate is what the next slice of pay is charged at — around 0.0% on the next ฿1,000 of gross. The marginal rate is the higher of the two, because the lower bands have already been taxed at less. It is the marginal rate, not the effective rate, that decides what a pay rise is actually worth.
