Skip to main content Small business accounting calendar: key tax dates and deadlines
As you get back into the swing of things in the new year, you might be wondering how to stay on top of your tax obligations throughout 2024.
To help put your mind at ease, we’ve put together a timeline of the most important accounting dates for business owners and freelancers during the year - including a download link to easily add this to your own calendar. Some businesses may have additional deadlines to track as well, like quarterly VAT returns or payments on account.
We’d also strongly recommend staying up to date with the latest developments in the government’s rollout of Making Tax Digital (MTD), its initiative to implement a fully digital tax system in the UK. Find out how MTD affects you and the timeline for all the upcoming changes.
Calendar of a typical small business tax year in the UK
Here’s how an average tax year for a UK-based small business might look. It’s important to bear in mind that the tax deadlines you have for your own business are unique to your circumstances, and your obligations to HMRC will depend on many factors. These include whether you have any employees or if you’re running your business as a ‘side hustle’ while in full-time employment.
For extra clarity on your tax obligations, we recommend working with an accountant if you’re not doing so already.

A note on VAT return deadlines
The vast majority of small businesses will file a VAT return four times a year. Making Tax Digital (MTD) for VAT legislation requires all VAT-registered businesses to do this through MTD-compliant software like FreeAgent. The most common set of quarterly VAT return dates is:
- 1st January - 31st March
- 1st April - 30th June
- 1st July - 30th September
- 1st October - 31st December
Each VAT return is due for filing one month and seven days after the end of one of these quarterly periods. So for example, the VAT return that covers 1st January - 31st March needs to be filed to HMRC by 7th May.
A note on payments on account
If less than 80% of your income is paid at source and your tax bill is over £1,000, you’ll need to make payments on account. These are advance payments on your next year’s Self Assessment tax bill. Your payments on account are calculated by dividing the amount of Income Tax and Class 4 National Insurance from your most recent Self Assessment tax return bill by two. You need to make the first payment by 31st January and the second payment by 31st July.
