This is a chapter from The 51%: Driving growth through women’s economic participation, edited by Diane Whitmore Schanzenbach and Ryan Nunn.
The current tax treatment of married couples reduces wives’ labor force participation and creates other inefficiencies. I propose a new second-earner deduction, equal to 15 percent of the earnings of a lower-earning spouse. The proposed deduction would raise the after-tax return to work for many wives, encouraging an increase in married women’s labor supply, and would reduce marriage penalties on average.
