Self Assessment deadline updates from HMRC

Official GOV.UK announcements and guidance changes about Self Assessment filing dates, payment dates, and Making Tax Digital (MTD) quarterly update deadlines. Each summary links to the source page on GOV.UK so filers can verify dates for their own tax year.

Updates begin soon — meanwhile, start with GOV.UK's Self Assessment guidance.
