It's the opposite. Obama, the chief enforcer of laws in our country, said "Our law is by definition a codification of morality." Lying is legal when society deems the lies to be acceptable or not wrong enough. Tax evasion, however, is considered to be morally wrong by society, hence it's illegal.

Still grasping at straws I see, now it's argument from authority, any more fallacies you want to throw out. Laws are not morals, illegal does not mean immoral nor does legal mean moral and I don't care who you quote, you're wrong and they're wrong.
