When US Tax Day is
According to the IRS, individual federal tax returns for a calendar year are due on 15 April, and if 15 April falls on a Saturday, Sunday or legal holiday the due date moves to the next business day. Emancipation Day, 16 April, is a legal holiday in Washington DC and moves the deadline for the whole country when it is observed on a date that would otherwise be the deadline.
Why the deadline moves
The deadline is 15 April unless a weekend or holiday pushes it later. When 15 April is a Saturday, the Monday after can be Emancipation Day observed, which is how the deadline reached 18 April in 2017 and 2023.
Public holidays before US Tax Day
Between today and Thursday 15 April 2027, the England and Wales count takes off Christmas Day (25 Dec 2026), Boxing Day (28 Dec 2026), New Year’s Day (1 Jan 2027), Good Friday (26 Mar 2027) and Easter Monday (29 Mar 2027), and the US count takes off Columbus Day (12 Oct 2026), Veterans Day (11 Nov 2026), Thanksgiving Day (26 Nov 2026), Christmas Day (25 Dec 2026), New Year's Day (1 Jan 2027), Birthday of Martin Luther King, Jr. (18 Jan 2027) and Washington's Birthday (15 Feb 2027). Holidays that fall at a weekend are already out of the count.

- UK working days take off England and Wales bank holidays from the GOV.UK feed, including substitute days. Scotland and Northern Ireland have different bank holidays.
- US working days take off federal holidays on the day they are observed under 5 U.S.C. 6103. States and employers can add their own holidays.
