UNDERSTANDING YOUR TAX OBLIGATIONS AS A SOLE TRADER:

Here’s what you need to know about being a sole trader and managing your tax obligations.

 

What is a Sole Trader?

​

A sole trader is someone who owns and operates their own business. It’s the simplest form of business structure, where you are personally responsible for the business’s debts and profits. As a sole trader, you’re essentially both the business owner and the employee, which means you must handle all aspects of your business's finances, including taxes.

 

Key Tax Responsibilities for Sole Traders

​

As a sole trader, you need to be aware of several key tax responsibilities, including income tax, National Insurance contributions, and VAT (if applicable). Here’s a breakdown of the most important areas:

​

1. Income Tax

As a sole trader, you’ll pay income tax on the profits you make from your business. Your profits are calculated by subtracting your business expenses (such as equipment, office supplies, or business-related travel) from your income. The current tax rates are:

  • Up to £12,570: 0% (personal allowance)

  • £12,571 to £50,270: 20% (basic rate)

  • £50,271 to £150,000: 40% (higher rate)

  • Above £150,000: 45% (additional rate)

​

2. National Insurance Contributions (NICs)

As a sole trader, you must pay two types of National Insurance contributions:

​

  • Class 2 NICs: A fixed weekly amount of £3.45 per week if your profits are above £6,725 per year.

  • Class 4 NICs: A percentage of your profits if they exceed £12,570. The current rate is 6% for profits between £12,570 and £50,270, and 2% on profits above £50,270. (Please note that these figures are subject to change with the tax year)

​​

These contributions go toward your state pension and other benefits.

​

3. VAT (Value Added Tax)

You must register for VAT if your taxable turnover exceeds £90,000 in a 12-month period (for 2024/25). Once registered, you’ll need to charge VAT on the goods and services you sell and submit quarterly VAT returns. You can also reclaim VAT on purchases you’ve made for your business.

​

If your turnover is below the VAT threshold, registration is optional. However, some sole traders choose to register voluntarily to reclaim VAT on their business expenses.

​

Claiming Business Expenses

​

One of the benefits of being a sole trader is that you can deduct certain business expenses from your profits before calculating your tax liability. This reduces your overall tax bill. Some common allowable expenses for sole traders include:

​

  • Business-related travel and transport costs

  • Office supplies and equipment

  • Utility bills (for the part of your home used for business)

  • Marketing and advertising costs

  • Professional fees (e.g., legal, accounting, or consultancy fees)

​​

It’s important to keep detailed records of all your business expenses so you can claim them accurately on your tax return.

​

Deadlines and Filing Your Tax Return

​

You must file your Self-Assessment tax return by January 31st each year, and any tax owed must be paid by this date. If you fail to meet the deadline, you may incur fines and interest charges.

​

In addition, if your tax liability exceeds £1,000, you’ll need to make payments on account—advance payments for the following year’s tax bill. These are due by January 31st and July 31st.

  • What is self-assessment?
    Self-assessment is a system or regime by which Her Majesty’s Revenue & Customs (HMRC) assesses and collects direct tax in the UK.
  • Should I complete a self-assessment tax return?
    Most people who pay income tax in the UK do not have to complete self-assessment tax returns. These are primarily employees whose tax is deducted at source under the Pay as you Earn system (PAYE). Self-assessment therefore applies to individuals such as the self-employed (sole traders) who earn in excess of £1,000, landlords that receive rental property income, individuals who receive income from savings, investments and dividends, foreign income, income from tips and commission and any other type of untaxed earnings.
  • When are self-assessment tax returns due?
    The UK tax year starts on 6 April each year and ends on 5 April of the following year. Self assessment returns are due on the 31 January following the end of the tax year. For individuals who wish to submit paper returns, the deadline is 31 October following the end of the tax year.
  • What are payments on account?
    Payments on account are amounts that some individuals are required to pay towards their estimated tax liability for the current tax year. They are calculated based on the previous tax years liability and are paid in two equal instalments of 50% each on the 31st January and the 31st July. These amounts are then deducted from the final liability for the year and a balance payment is usually made, together with a first payment on account for the following tax year.
  • How do I get the ball rolling?
    As a starting point, you would need to register with HMRC in order to receive your 10 digit Unique Tax Payer Reference number (UTR). This number will enable you to submit your tax returns online by the 31st January deadline. If you are completing your own tax return, you would need to create an online account with HMRC once you receive your UTR number. Alternatively, if you need to help and support with getting your tax affairs complete and up to date then please get in touch for your free consultation.
