Supreme Court gay marriage ruling will affect 179 federal tax provisions and thousands of same-sex couples

June 10, 2013

Sometime this month, the U.S. Supreme Court will decide two gay marriage cases, California's Proposition 8 legalizing same-sex marriages in that state and the federal Defense of Marriage Act, or DOMA, which defines marriage for federal purposes as being the exchange of vows between one man and one woman.

The justices' opinions will affect the hundreds of thousands of gay couples who, under their states' laws, are married or who hope to one day marry.

Most of those couples want to exchange vows because they love one
another. But, as a tax geek bride who pushed her wedding date into
a new year partially for tax reasons
, we can't ignore the tax consequences, good and bad, of being married in the eyes of the Internal
Revenue Service.

A 2004 Government Accountability Offices, or GAO (which until July
of that year was called the General Accounting Office) analysis found
there were 1,138 federal laws in which marital status is a factor. Of
those statutes, 179 were part of the Internal Revenue Code.

Both the overall number of laws and the number of tax-specific
provisions cited in 2004 were an increase from the GAO's 1996 look into
the matter following the enactment of the DOMA. Back then, the GAO
counted 1,049 total marriage-related federal statutes and 59 tax provisions.

So in recognition of the increase in marriage-related tax laws, which
I'm sure have grown even more since the GAO last looked nine years ago,
and the impending Supreme Court ruling on DOMA, 179 is this week's By the Numbers figure.

For better or worse, in taxes too: Most married couples find that they benefit from federal tax laws when it comes to their joint filing status. Some heterosexual couples, however, find that their particular situations mean the tax code costs them.

It's that same marital tax treatment, for better or worse, that same-sex couples are seeking. 

And while most folks, regardless of their sexual orientation, will deal with the IRS on relatively routine matters, such as filing status and tax credit and deduction claims, marital status concerns also come into play when there are estate and gift tax considerations.

When your spouse is the same sex as you, estate tax planning and costs can increase substantially.

In fact, if was those differing estate tax costs for a lesbian married couple that prompted the filing of the DOMA lawsuit now before the Supreme Court.

Tax Season 2026 Continues!

We made it. Tax Day 2025 is finally over. For most of us. When the filing season started on Jan. 26, millions who were expecting refunds filed immediately. Most of us got our returns to the Internal Revenue Service by April 15. But plenty of taxpayers also got extensions. They are looking at an Oct. 15 filing deadline.

Those procrastinating filers aren’t a problem. In fact, the IRS appreciates taxpayers who take time to fill out their 1040 forms correctly. It also is grateful that tax submissions are spread out a bit, especially now that the IRS is a leaner agency. Processing returns is easier when they arrive throughout the year instead of in massive bunches.

But enough about Uncle Sam’s tax collection issues. The focus now is on all y’all who filed for extensions, giving you another six months to complete your return. Since your new mid-October due date will be here before you know it, let’s get started now on meeting it.

The ol’ blog is here to help you finish up your extended Form 1040. You can start with January’s tax tips page, which has links to the rest of the year’s tips by-month collections. You also can peruse various tax categories for more tailored advice by clicking on the More Tax Posts drop-down menu at the top of this (and every) page.

And to make sure you don’t miss your new filing deadline, the count-down clock below will let you know just how much time you to file by Oct. 15. At the latest.e. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
