Explain which taxes are paid by the employer and which are paid by the employee. Choose one of these and explain what these taxes pay for? Consider federal, state, or local taxes. For example, who pays Tri-Met taxes? Is it local, is it restricted to certain areas of Oregon or do all Oregonian's pay it? What does it pay for? Who pays it, employer or employee or is it a match?
