You can't ask them to issue 1099s instead? I assume you know this but when they issue W-2s, they need to pay the employer portion (7.65%) of Medicare and Social Security on your "wages" plus federal and possibly state unemployment. Why would they do that? Also, if you need to substantiate your partnership income, a W-2 is not going to suffice. A W-2 will say that you were an employee of your client. I'm with your accountant on this. Your client should have no trouble issuing you 1099s, it will save them money.
