As a married couple, you probably share almost everything. But is that such a good idea when it comes to filing taxes? Most couples file their return jointly, combining incomes and sharing deductions. This filing season, same-sex married couples also will decide whether to file one federal 1040 or two forms as married filing separately. The trend to file jointly will probably continue, encouraged in large part by tax-law changes during the past few years to ease the marriage penalty.
