Financial guru Suze Orman on Monday discussed the implications of the Defense of Marriage Act (DOMA) on gay couples as it relates to taxes.

Orman, who in 2010 married her wife Kathy Travis in South Africa, commented on the law during a conference call coordinated by the Respect for Marriage Coalition, which lobbies for marriage equality.

“In order to be financially secure now and in the future, same-sex couples have to devote time to financial and estate planning,” said Orman, the host of CNBC's The Suze Orman Show. “DOMA requires families to look ahead and plan a budget around its restriction, which include higher federal taxes and tax penalties on benefits.”

Mark Maxwell and Tim Young-Maxwell of North Carolina, who have been together for over two decades and married in January in the District of Columbia, are raising four adopted children.

“We pay twice as much for our accounting fees each year for him to navigate his way through filing our taxes,” said Young. “Because of DOMA, we have to file our federal taxes as if we were single, which creates additional confusing steps that we wouldn't have to do if we were a heterosexual couple. And, because both our state and the federal government don't recognize our marriage, Mark and I have had to split up the family during tax season, which is heartbreaking.”

Orman advised that once DOMA is overturned, which she believes to be inevitable, married gay and lesbian couples should consider moving to states where their marriages are recognized.
