Form SS-8 Determination vs Section 530 Relief

If the IRS determines that a business should have been treating workers as employees rather than independent contractors, there is a possible way to avoid paying back employment taxes. The IRS has set up a process under Section 530 of the Internal Revenue Code with three criteria for an exemption from this payment.​ Section 530 relief is a separate process from an SS-8 determination.
