US Trends

when do tax returns have to be done by

For most people filing a standard U.S. individual tax return, the deadline is mid‑April each year, with an option to request an extension to mid‑October.

Key U.S. Deadlines (Current Season)

  • Main deadline (Tax Day):
    For your 2025 income (the return you file in 2026), the federal filing deadline is April 15, 2026.
  • Extension deadline:
    If you file an extension by April 15, you usually have until October 15, 2026 to submit the return itself.
  • Important catch:
    An extension gives more time to file , not more time to pay. Any tax you owe is still due by April 15 to avoid interest and penalties.

Here’s a quick HTML table you can reuse:

If You’re Asking About the UK

A lot of forum threads with this question are actually about UK self‑assessment , which has very different dates:

  • Online self‑assessment returns: Due by 31 January after the end of the tax year.
  • Paper returns: Earlier, usually 31 October.
  • Payments: Balancing payment and first payment on account often also due by 31 January.

If you tell which country you’re in (US, UK, etc.) and whether you’re self‑employed, working PAYE, running a company, etc., a more tailored breakdown can be given.

Quick forum‑style rule of thumb:

  • U.S. individual taxes → think April 15 (with possible extension to October).
  • UK self‑assessment → think 31 January for online returns (and payment).

TL;DR:

  • U.S. individual federal return: April 15 (extension to October 15 if requested; money still due April 15).
  • UK online self‑assessment: 31 January following the tax year end.
