The general tax deadline for individual federal income tax returns in the United States is April 15 each year, unless this date falls on a weekend or public holiday, in which case it moves to the next business day. For the 2024 tax year, the deadline to file without extension is April 15, 2025. There is an option to request a six-month extension by submitting Form 4868, which extends the deadline to October 15, 2025. For business tax returns like partnerships or S-Corps, the deadline is typically March 15, and for C corporations, it is April 15, with possible extensions if the date falls on a weekend or holiday.
For other countries, for example Germany, the deadline for submitting the 2024 income tax return is July 31, 2025, with an extension available until February 28, 2026 if a tax advisor is used.
For the UK, if you file a Self Assessment tax return, deadlines vary but paper returns must be submitted by October 31, 2025, and the deadline to pay any tax owed is January 31, 2026.
If you want to know the tax deadline for a specific country or type of tax, please specify.
