Why is Tax Day April 18?
The regular tax return filing deadline is April 15. However, due to April 15 being on a Saturday and the Washington D.C. Emancipation Day holiday being observed on April 17 instead of April 16, 2017, Tax Day is on the following Tuesday.
When Can I File My Previous Year or Late Federal Tax Return?
There is no IRS deadline for overdue previous year tax returns, but in order to claim a tax refund for a certain year, you must file a tax return for that year within 3 years of the original due date. If you wait longer than 3 years, any tax refund is forfeit.
