Tax Day is a typically American phenomena, the last day to file due tax returns to the federal government and wrap up a financial year. It has been categorically observed on April 15th every year.

The day has a long overdrawn history dating back to the Civil War era. According to older traditions, taxes were collected based on assessments, functioning loosely under the Revenue Act 1861.There was no strict deadline or organizational structure to enforce a due date per say.
