The Supreme Court’s decision to invalidate the Defense of Marriage Act means that gay married couples will have access to the federal benefits now enjoyed by other marrieds.

These benefits include tax breaks, Social Security benefits and estate planning advantages that until now were denied gay couples, even if their marriages were recognized under state law.

Among other things, gay marrieds will now be able to:

• claim Social Security benefits based on a spouse’s working record and qualify for survivor benefits.
• fund an IRA or Roth IRA for a nonworking spouse.
• split a retirement fund or other assets without triggering tax bills if they divorce.
• exempt health care benefits for a spouse from their federal income.
• bequeath their estate to a spouse without triggering potential federal estate taxes.

These gains may come with a cost: as NerdWallet puts it, “federal income tax brackets are in fact easier on high-income individuals than they are on most high-income married couples.” NerdWallet figured that same-sex couples earning more than $146,000 may see their tax bill go up by over $1,000.

One of my gay friends, a financial planner, just posted to her Facebook page that her taxes are likely to go up by several thousand dollars. But she was happy, as she put it, to “take one for the team.”
