Accounting periods
For all the business deadlines we list we have assumed that a company's accounting period runs to the end of the relevant month (ie 31 March for March year-end businesses). If your year end is not at the end of a calendar month, please get in touch.
For simplicity, the deadlines listed relate to companies with a 12-month period of account although it is possible to have longer (up to 18 months) or shorter accounting periods. However, please note that the period covered by your tax return (your ‘accounting period’ for Corporation Tax) cannot be longer than 12 months. Therefore, you may have to file two tax returns to cover longer accounting periods, and each return will have its own payment and filing deadlines. For help on non-standard accounting periods, please get in touch.
(1) Large company for SAO purposes
All UK incorporated companies with UK turnover of more than £200m and/or balance sheet total of more than £2bn in the last financial year (or members of a group that exceeds these limits).
(2) OECD’s ‘Country-by-Country Reporting’ framework threshold
Companies or groups who are part of a Multi-National Enterprise (MNE) group that has a global annual turnover over 750 million euro.
Where country-by-country reporting applies, qualifying company/group must compile and submit a summary showing and overview of allocation of income, taxes and business activities by tax jurisdiction and a list of all constituent entities in each tax jurisdiction and their main business activity with their transfer pricing documentation within 12 months of the end of the accounting period.
UK companies within the country-by-country reporting rules must notify HMRC of where the report for that accounting period will be filed if not in the UK.
(3) Pillar two
Companies or groups who are part of a Multi-National Enterprise (MNE) group that has a global annual turnover over 750 million euro in at least two of the prior four accounting periods.
(4) Corporation tax quarterly instalments - "very large"
Companies are "very large" and must make instalment payments where taxable profits in the current accounting period are expected to exceed £20m. The £20m threshold must be time apportioned for accounting periods less than 12 months and split between group companies where there are one or more related 51% group companies. Payment is 25% of estimated total liability for the year.
(5) Corporation tax quarterly instalments - "large"
Companies are "large" and must make instalment payments where taxable profits in one of the two prior accounting period are between £1.5m and £20m. The £1.5m threshold must be split between group companies where there are one or more related 51% group companies. Payment is 25% of estimated total liability for the year.
(6) VAT stagger
Your quarter and VAT year end dates will depend on the stagger group you choose on registration or that is allocated to you by HMRC:
Quarter ending:
(7) VAT quarterly large scheme
Where annual VAT payments will exceed £2.3m companies must submit a quarterly VAT return one calendar month after the end of their VAT quarter. VAT instalment payments must be made on the last working day of the second and third months of every VAT quarterly period with balancing payments one calendar month after the end of your VAT quarter.
(8) VAT Annual accounting scheme
The annual accounting scheme (one VAT Return a year) is available for businesses to opt into where their annual turnover is £1.35m or less. VAT instalment payments must be made at the end of months, 4, 5, 6, 7, 8, 9, 10, 11 and 12 of your VAT year - calculated as 10% of the prior years’ net VAT liability.
(9) Tax year
Starting on 6 April and ending on the following 5 April.
