Under the new deal, if you're a woman who makes $225,000 a year, and so does the love of your life, your tax rate will be a lot lower -- if "Single Ladies" by Beyonce is your theme song.
But, if "Love and Marriage" is more your thing, you may be in for a tax hike. Bob Williams, with the Tax Policy Center says the new top rates include a big marriage penalty, "but not as big as last year," he says.
In fact, according to Williams, the new tax rates give high earning married couples a bit of a break, compared to the last decade. But slide down the income ladder to the bottom two tax brackets, and at those levels, there's no marriage penalty under the new tax deal.
Isabel Sawhill, a poverty expert at the Brookings Institution, says removing barriers for marriage helps reduce child poverty.
"Two people can combine their incomes, can live more cheaply than one," says Sawhill.
Sawhill doubts taxes will ever be the deciding factor for popping the question, but she says sometimes, it can tip the balance.
