Marriage can be a wonderful thing, but for some couples it can also be a costly institution come tax time.
In general, many couples enjoy what's called a marriage bonus—they actually get a tax break for being married. But others are subject to a marriage penalty, meaning that they pay more in taxes than if they were each single.
Several relatively new tax provisions could result in some people paying higher marriage penalties this tax season, especially if they are among the nation's biggest earners, said Roberton Williams, a fellow at the Tax Policy Center.
That's because the provisions are mainly geared toward people who make a lot of money. One provision is aimed only at earnings over $200,000 for singles and $250,000 for couples, for example. Another subjects singles earning $400,000 or more, or couples earning $450,000 or more and filing jointly, to higher tax rates. When two high earners combine their high incomes, they are more likely to hit with those higher thresholds.
