¿Cuál es la diferencia entre el tipo impositivo marginal y el tipo efectivo en California?
El tipo marginal es el porcentaje que se aplica al último dólar de ingresos imponibles. El tipo efectivo es el impuesto total dividido entre los ingresos totales, y siempre es menor que el marginal en sistemas progresivos. Por ejemplo, si el tipo marginal es el 6% pero los primeros tramos tributan menos, el tipo efectivo puede quedar por debajo del 4%.
