You don't avoid it all via the S-Corp. You just avoid the half the employer (in this case, also you) normally pays. I'm not a tax accountant or a lawyer, just happen to run my own consulting through an S-Corp. I still pay myself around half of the net revenue the S-Corp brings in as a regular employee, and that portion is taxed under FICA.
