The median income for a US household is about $50,000. I ran this figure for single, married, and married with 2 children.
Under Cain’s plan (which has many details that have not been released), the household’s tax would be $4,500.
Single folks making 50k would receive a tax break. Under today’s law, a single person taking the standard deduction would have tax of $6,256. Cain’s plan would reduce taxes by $1,756.
