Unfortunately, it's not that simple. I can't provide health insurance to my partner and we pay quite a bit more in taxes than a married couple.
I would like to not pay more because of whom I choose to marry.
I'm all for marrying who you want, but if you live in the US your tax comment doesn't make sense.
Umm... did you actually read the link that you just cited? “Multiple factors are involved, but in general, lower to middle income couples usually benefit from filing as a married couple, while upper income couples are often penalized.”
Or are you straight and hence it doesn't affect you? Kinda defeats the point of donating to charities...
