I have a few guys working for me in California, so the contractor who pays my company with holds 7% from invoice payment, only for hours worked, not expenses. Can that 7% be refunded or have I just gave CA 7% of my billing? I did not find out about this until six weeks into the job. I have done work all over the USA and internationally and never heard of this 7% withholding. Have you ever heard of anyone getting any money back?
