The Defense of Marriage Act forbids legally married same-sex couples
from filing their federal taxes jointly, forcing them to lie to the
Internal Revenue Service and declare themselves single. But in states
such as New Jersey, where couples in civil unions are allowed to file
jointly, couples must fill out a joint federal return anyway in order to
feed data to their state forms, making the exercise far more costly
and time-consuming. LGBT groups plan to highlight the disparity today
in advertisements and protests calling for the repeal of DOMA.
