I don't see how it could calculate what my tax burden would be based on my income alone. It's not asking me if I'm self employed or if I have dependents.
Consultants like myself have to pay the payroll taxes (SSI, Medicare) for themselves as well as the employer contribution - which this doesn't mention. I suppose it's just looking at income tax?
Who do I vote for if I want to torch the current federal tax system and replace it with a federal sales tax?
