The threshold rates for a lot of credits, deductions and exemptions are not. Like the Roth IRA is $153k for single, $242k for married. Child care credits have a similar problem if I remember correctly (or they did before my kids grew out of it).

Plus states and counties do it too.

Portland, OR metro gives a $125k threshold to single and only $200k to married filing jointly for supportive housing taxes, which is a 1% tax on income above the threshold.

I have no idea why households that tend to demand less housing (married usually live together) are charged more than singles, who typically demand their own housing at that income level. It makes no sense!

Because households that share housing have more disposable income than individuals living by themselves.

The thought being it's okay to steal from married households because they intentionally set themselves up for lower per partner overhead? Why don't we charge single taxpayers with roommates on the same schedule?

By living in a single house, a married couple demands less housing, which reduces the cost of housing against a fixed supply. Why are we taxing the people making housing cheaper under the guise of "affordable housing"? Shouldn't we treat affordable housing taxes like the carpool lane and reduce the burden of those that are reducing the burden on the constrained supply?
