Tax all male* wages at 20%, PAYE, split equally between employer and employee. This would create a strong disinsentive for companies to hire male workers over equally qualified female workers, thus forcing more men into domestic labor as their wives became the breadwinner.

*Biological males, including post-op men-born-women.
