⚡️When is Tax Day?

Tax Day is as inevitable as taxes—it comes around every year. Tax Day most commonly falls on April 15, but it is sometimes moved due to varying circumstances, including when April 15 is a Friday, Saturday, or Sunday. In those cases, Tax Day moves to the following Monday or Tuesday. Sometimes, Tax Day is moved for other reasons. In 2021, Tax Day was moved to May 17 due to tax code changes resulting from the COVID-19 relief package.

Income tax in the US was first collected during the Civil War, but the law that enacted the tax was repealed in 1871. A new income tax law was passed in 1894 but was soon ruled unconstitutional by the Supreme Court. This meant that in order for the government to collect income tax, the constitution would have to be amended—which it was, in 1913, with the 16th Amendment. Tax Day was first set as March 1, then moved to March 15 in 1918, and finally to April 15 in 1955.

The March 15 filing deadline remained on the books for a long time. Not until 1955 did taxpayers face a new deadline. The Internal Revenue Code of 1954 established April 15 as the tax day we all know and loathe.
