I have been working part time for a marketing company and recently realized that they have a strange way of computing pay. The pay rate that they quote me varies by job between $10 and $17 per hour. When I look at the detailed breakdown of the pay paperwork they list my pay as minium wage and the rest as "mileage" pay. So if my pay rate for a particular job is $10, it is listed as hourly rate $7.25 and mileage pay $2.75. If my pay for another job is $15 it still lists my hourly rate as $7.25 and mileage as $7.75. This is without regard as to any actual miles that I drive. This seems to me like this is just a way to avoid paying social security and other tax. Does anyone know if this is legal?
