How this list is kept up to date
Each date comes from GOV.UK, HMRC or Companies House, linked on the row. When the government announces a change, we update the row and the guide on the same day; dates that have passed move to the bottom. Personal deadlines (your own confirmation statement, your own MTD start) can differ from the headline dates: the linked guides include calculators for those.
