We get two extra days because April 15 is a Sunday and April 16 is Emancipation Day (a legal holiday in the District of Columbia). April 16 also happens to be Patriots Day in Massachusetts, where an IRS processing facility for the eastern states is located.
April 17 deadline applies to:
- 2006 federal individual income tax returns, whether filed electronically or on paper
- requests for an automatic six-month tax-filing extension, whether submitted electronically or on Form 4868
- tax year 2006 balance due payments, whether made electronically (direct debit or credit card) or by check
- tax-year 2006 contributions to a Roth or traditional IRA.
- individual estimated tax payments for the first quarter of 2007, whether made electronically or by check
- individual refund claims for tax year 2003, where the regular three-year statute of limitations is expiring
