FAQs: Tax Management

You should complete your Self Assessment Tax return annually.

You have up until a year after the submission deadline. For example, if you are filing your 2018/19 return, the deadline is 31st January 2020, meaning you would have until 31st January 2021 to amend the return.

The 31st of October for paper returns and 31st of January for online returns.

If you miss the deadline, you will immediately receive a £100 penalty from HMRC. If the return is still not received within three months of the filing date, you will be charged £10 a day (up to £900). If it is still not received by six months (31st July), you will receive an additional £300 penalty, and a further £300 penalty is also charged after 12 months. Please be aware that interest will also be due on top of these penalties made by HMRC

The tax year starts on the 6th of April and ends on the following 5th of April.

A UTR number is a unique taxpayer reference number. It is 10 digits long, and you are given one by HMRC when you register for self-employment.

You usually pay 2 types of National Insurance Contributions (NICs) if you’re self-employed, Class 2 and Class 4.

For the 2020-21 tax year, the thresholds changed:

  • The small profits threshold has increased from £6,365 to £6,475. This means you'll start paying Class 2 NICS when you earn more than £6,475.
  • Class 2 NICs are now £3.05 per week, instead of £3.00. 
  • Class 4 NICs are now paid when you earn more than £9,500, rather than the previous figure of £8,632. You'll pay 9% of your profits between £9,500 and £50,000 per year and 2% of anything you earn above that. 

Tax relief means that you pay less tax to account for money that you have spent on business expenses. Your income is reduced by the amount of expenses that you claim, therefore reducing the amount of tax you pay.
