This process can take up a lot of the consultant's time normally spent working on projects. By joining, a consultant can concentrate on their profession instead of worrying about back office responsibilities. 

Furthermore, any businesses who improperly classified their workers as 1099 when they should have been W-2 may have to end up paying the employer side of taxes which weren't paid earlier. This doesn't include any penalties which the IRS may choose to file against the company. By joining IAI the employer can eliminate co-employment risk completely.
