We may forget birthdays and anniversaries; but I doubt anyone forgets that April 15th is the day of reckoning for personal income taxes in the United States. Given that today is April 15th, we should take a closer look at the origin. The implementation of the personal income tax was the direct result of Congress passing the sixteenth Amendment on February 3rd, 1913 with the deadline for filing being chosen as March 1st of the following year. The deadline was changed to March 15th in 1918, for unknown reasons. The last time the deadline was moved, it became April 15th in 1955. For the last 55-years April 15th has been the deadline for personal income taxes.
