When you set up your own company, your business is automatically registered for Corporation Tax as part of the registration process. Therefore, at this point, HMRC will give you login details for your Business Tax account.

Tax year-end of tax year (UK)
In the UK, there is are two types of tax years which run from certain dates in the calendar year. Basically, in the United Kingdom, the tax year end date is the last date in the tax year. In addition, the date after this is the first day of the tax year. Therefore, when there are any changes to UK tax allowances or tax rates this is the date when they will usually take effect. Therefore, the UK tax year end date is:
- 5 April for the UK personal tax year end. A brand-new tax year starts on 6 April. Therefore, the date that UK personal tax returns are made up to each year is 5 April. Basically, if you are required to file a personal tax return, this falls under the UK Self Assessment system. Furthermore, when you complete a UK personal tax return it will include your income from 6 April to 5 April. Therefore, for 2022/23, it will cover your income received from 6 April 2022 to 5 April 2023. Likewise, for 2023/24 it will cover your income from 6 April 2023 to 5 April 2024. What’s more, when there are changes by the government to personal tax rules, they will come in from the start of a new tax year.
- 31 March for the company tax year, also known as the Corporation Tax year. Therefore, this is the date that any changes in company tax rates will take effect. As a result, if the government changes the Corporation Tax rate, it will take effect on 1 April.
Besides the tax year, there is also your financial year. The last day of this is usually the last day of a calendar month and this is known as your company year-end or accounting reference date. Therefore, this is the date of the end of year accounts and the date accounts are made up to for your company each year.
You can set the company year-end yourself when you set your company up. However, you can also change it at a future point in time. What’s more, if you do not choose a company year-end when your company is set up, it will automatically default to the end of the calendar month in which your company was incorporated. Certainly, this is how a company year end is chosen. Therefore, you should be this in mind for your own company.
If your company was incorporated on 20 July 2023 and you did not set your year-end, it would automatically default to 31 July 2024. As a result, you would file your accounts up to 31 July each year in future. However, you could decide to change the company year-end at a future date.

Basically, it is much simpler to have your year-end on 5 April in a personal tax context. What’s more, the majority of self-employed people will choose 31 March or 5 April as their business year-end.
It is important to remember that your company should save its tax liabilities as it goes along in the company bank account.

In addition. for those with income over £30,000, this will now be mandated from April 2027. What’s more, the scope also has plans to extend this to company tax returns in the future too. This was originally planned for April 2026; however, it now looks even further away.
Filing company accounts and limited company tax return online
A company will file its accounts with Companies House online via specialist software. In addition, it will also file corporation tax online and as part of the same process, go ahead with filing company accounts online. Again, specialist software is required to perform this process.
