What are the key differences between a sole trader and a limited company?
A sole trader operates their business personally, bearing unlimited liability, whereas a limited company is a separate legal entity, offering limited liability protection. Taxation differs: sole traders pay Income Tax on profits, while limited companies pay Corporation Tax on profits and may distribute income via dividends. Choosing the appropriate structure depends on factors like income level, risk, and long-term business goals.
What are the key deadlines for Self Assessment?
- 31 October: deadline for paper tax returns.
- 31 January: deadline for online tax returns and payment of any tax owed.
- 31 July: deadline for the second payment on account.
- 5 April: end of the tax year.
What happens if I miss a tax deadline?
Failing to meet tax deadlines can result in penalties and interest charges. For instance, a £100 penalty is imposed for a late Self Assessment return, with additional penalties accruing over time. It’s crucial to submit returns and payments on time to avoid unnecessary costs.
When do I have to join Making Tax Digital?
Making Tax Digital for Income Tax started on 6 April 2026. If your qualifying income from self-employment and property was over £50,000 on your 2024/25 tax return, you should already be using it. If it is over £30,000 on your 2025/26 return, you’ll need to use it from 6 April 2027, and if it is over £20,000 on your 2026/27 return, from 6 April 2028.
Will MTD change the dates when I pay tax?
No. The way you pay tax and the dates payments are due stay the same, and your tax return is still due by 31 January after the end of the tax year. What changes is when and how you send your records: quarterly updates through compatible software.
