I guess certain cities like NYC/Philadelphia might also push effective income tax to over 30% for lower incomes, but for the purposes of comparing income tax rates and capital gains tax rates in the US, it does not make sense to include the social security component of FICA or medical costs.

Edit: I am barely getting 30% in NYC, even including FICA (zip code 10118)

$90k as single is $27,171, or 30.19%.

$90k as married filer shows $20,758, which is 23.06% (incl FICA).

But, again, I would not include all of the social security portion of FICA (6.2%), since presumably you will be getting some of that back.
