Marriage Penalties and Bonuses (Families with Children Edition)

My colleague Liz Malm re-posted a marriage penalty chart I created a few months ago. I've used a similar technique to create two more charts to go along with it, showing the same figures for households with one and two dependents. (These were created by running our online income tax calculator in a loop. For each single filing status calculation I tried all possible combinations of dividing up the dependents and took the lowest tax configuration.)

Marriage Penalties and Bonuses for Various Households

These charts were featured in our most recent issue of Tax Watch and appear on the blog for the first time here.
