Due to the Patriots Day holiday, residents of Maine, Maryland, Massachusetts, New Hampshire, New York, Vermont and the District of Columbia will have until Tuesday, April 18.
Is this fair? I think NOT! I say everyone is entitled to an EQUAL right to procrastinate until the last dang minute and this denies me, a citizen of Oregon, an equal right to the good people of Mass.
I think it was New England patriot Patrick Henry who said "Give me more time to file my taxes or give me a deduction"

It’s a mom and apple pie issue, Joeduck old son — the problem is, Patriot’s Day is a school holiday in Massachusetts, which is where the 12 states affected send their taxes (to the Andover center, which oddly enough is right across the street from my old gym). I’ll bet their absenteeism rate would be so high on Mondays when Patriot’s Day and tax day would coincide that they have just given it up as a bad job.
But don’t fret; everyone can file an extension and get a deadline in October that’s not affected by a New England holiday ;^)
