If you are married, then you and your spouse can file separate tax returns. The married filing separately (MFS) filing status is generally perceived as the least beneficial of all the filing statuses.
In 1783 Congress decided to create a new capital apart from any state, and in 1787 the framers of the Constitution provided for a capital district. The U.S. capital was originally Philadelphia. Washington D.C. became the new capital on July 16, 1790.
Here's Why Washington D.C. Isn't a State. With Washington, D.C.'s mayor calling for a November vote on statehood, it raises the question, why wasn't the nation's capital made a state in the first place? First, it's worth remembering that Washington, D.C. was not always the capital. George Washington first took office in New York City, and then the capital was moved to Philadelphia, where it remained for a decade. Washington, D.C. was founded as the capital in 1790 as a result of a compromise between Alexander Hamilton and northern states, and Thomas Jefferson and southern states.
