The filing deadline to submit 2017 tax returns is Tuesday, April 17, 2018, rather than the traditional April 15 date.
In 2018, April 15 falls on a Sunday, and this would usually move the filing deadline to the following Monday – April 16. However, Emancipation Day – a legal holiday in the District of Columbia – will be observed on that Monday, which pushes the nation’s filing deadline to Tuesday, April 17, 2018. Under the tax law, legal holidays in the District of Columbia affect the filing deadline across the nation.
