The IRS announced today that the deadline to file your tax return has been pushed back to Tuesday, April 17th (the deadline was originally Monday, April 16th because the 15th falls on a Sunday). The IRS release is available here.
California will follow along, according to today’s release from the Franchise Tax Board.
Why the change? Because April 16th is Emancipation Day, a legal holiday in the District of Columbia. Under federal statutes enacted years (decades?) ago, when the tax deadline falls on a Saturday, Sunday, or legal holiday in the District of Columbia, the deadline is extended to the next business day. Emancipation Day is a new holiday in the District; thus, the change.
