The filing deadline for individuals was March 1 in 1913 (the first year of a federal income tax), and was changed to March 15 in 1918 and again to April 15 in 1955.[8] Today, the filing deadline for U.S. federal income tax returns for individuals remains April 15 or, in the event that the 15th falls on a Saturday, Sunday or holiday, the first succeeding day that is not a Saturday, Sunday or holiday.[citation needed][inconsistent]
