How these dates are worked out
Dates come from your settings and leave the list the day after they are due.
Accounts are due nine months after the year end; for a first year over twelve months, 21 months after incorporation.
Corporation Tax periods run from incorporation, twelve months at most; tax for each is due nine months and a day after it ends. The Company Tax Return is due a year after the accounts end.
A confirmation statement is due 14 days after each year from incorporation.
For a first year over twelve months, the Company Tax Return dates and when Corporation Tax starts are worth confirming with your accountant.
Not covered: PAYE, s455, a changed year end, or trading that started after incorporation.
