In short
A limited company files annual accounts with Companies House 9 months after its financial year ends (its first accounts, 21 months after it registered), pays Corporation Tax 9 months and 1 day after its accounting period, and files its Company Tax Return 12 months after. A confirmation statement is due at least once a year.
Every date runs from your year end.

Sellers' accounts turn on the stock figure.
A company keeps records of the stock it owns at the end of the financial year, the stocktakings used to work out that figure, and all goods bought and sold. On Growth and Scale, we record cost of goods sold as items sell through the year, then agree it to your stock count at the year end. On every plan, your year-end accounts use your stock count at the year end.
Company records are kept for 6 years from the end of the last company financial year.
