How Much Tax Do Contractors Pay in the UK

Updated: Jun 29

Contracting in the UK comes with its own unique set of tax considerations. As a contractor, you are likely to operate through a limited company, which means you are subject to a variety of taxes, including Corporation Tax, Employer's National Insurance Contributions (NICs), VAT, and Income Tax. Understanding these taxes and how they apply to you is crucial to ensure you are operating in the most tax-efficient manner.


How Much Tax Do Contractors Pay in the UK


Understanding the Tax Landscape for Contractors

Understanding the tax landscape for contractors in the UK is crucial for operating in the most tax-efficient manner. By understanding the different taxes that apply to you and how they are calculated, you can make informed decisions about your salary and dividends, and ensure you are meeting your tax obligations.


Limited Company Tax

As a contractor operating through a limited company, you are subject to Corporation Tax on your company's profits. The current rate for the 2024/25 tax year is 25%. The rate is 19% for profits up to £50,000. For profits between £50,000 and £250,000, there's a marginal rate that gradually increases the effective tax rate up to 25% for profits above £250,000​. This means that if your company invoices a client £250,001 excluding VAT over the year and has expenses of £50,000, you will pay 25% Corporation Tax on the remaining £200,001. The company’s Corporation Tax is due nine months and one day after the year-end.


Employer's National Insurance Contributions

Your company will pay 13.8% on any salary you pay yourself over the threshold of £175 per week. However, there is no National Insurance to pay on dividends. This flexibility allows you to structure your income in the most tax-efficient manner. If you work through an umbrella company, you will have to pay the Employee's National Insurance of 13.25% and Employer's National Insurance of 15.05%.


VAT (Value Added Tax)

As a contractor, you’ll more than likely be registered for VAT. You charge this on your invoices at 20%. Most contractors also apply and register for the Flat Rate VAT Scheme, which means you charge 20% but then repay at a lower rate. You are entitled to a discount of 1% during your first year in the scheme. However, the difference you keep is considered a profit and is therefore subject to Corporation Tax.


Income Tax and PAYE

Income Tax can be a complicated subject due to the ability to draw money from your company in two ways: Salary (as an employee) and Dividends (as a shareholder). Any income taken as salary beyond your personal tax allowance of £12,570 (2022/23) is taxed in the following ways:

  • 20% on earnings between £12,571 and £50,270

  • 40% on earnings between £50,271 and £150,000

  • 45% on earnings above £150,000


It is also worth mentioning that once you earn beyond £100,000, your personal allowance will be reduced at a rate of £1 for every £2 of income until it is reduced to zero. By the time you hit £125,000, your personal allowance will have disappeared, meaning that your income between £100,000 and £125,000 will have been taxed at 60%.


Employee's National Insurance Contribution

There is no National Insurance (NI) on dividends. You’ll pay NI on a salary which is 13.25% on anything you earn above £190 per week. After you earn £967 per week, you’ll pay a rate of 3.25% on anything above this limit.


Comparing Taxes: Contractors Versus Employees

Contrary to popular belief, contractors receive relatively modest tax advantages, especially considering the employment rights and security that they forego in order to work flexibly. The tax advantages experienced by contractors are often grossly exaggerated. In particular, the April 2016 dividend tax changes have helped to significantly narrow the comparative tax take from contractors and employees.


Deciding What’s Right for You

There are a number of questions you should ask yourself and consider when deciding on your salary:

  • What income tax and NICs efficiencies do you want to achieve?

  • Do you want to ensure that you retain your right to a state-earned pension and other benefit entitlements?

  • What level of contribution do you want to set for your pension this year?

  • Do you need to demonstrate a certain salary level for any reason e.g. income for borrowing purposes?

  • Do you have other sources of income?

How Much CIS Tax Do Contractors Pay

In the UK, contractors in the construction industry are subject to the Construction Industry Scheme (CIS) tax. This tax is deducted at source from payments relating to construction work, calculated based on labour and material costs. There are three different CIS tax rates applicable to subcontractors: 30%, 20%, and 0%.


  1. 30% CIS Tax Rate: This is the highest CIS tax rate and applies to subcontractors who choose not to register for the CIS. This rate is typically unattractive due to its significant impact on cash flow, so most subcontractors opt to register for the CIS to benefit from a lower tax rate.

  2. 20% CIS Tax Rate: Subcontractors who register with the CIS are subject to a lower tax rate of 20%. This rate is typically chosen by smaller subcontractors, often with a turnover under £30,000. The deductions can be used to offset against their personal tax liabilities or their corporation tax liability.

  3. 0% CIS Tax Rate: Businesses can choose to register for gross payment status, which results in a CIS tax rate of 0%. These businesses, known as gross subcontractors, receive payments in full from their contractors with no deductions. This is beneficial for cash flow in the short term, but these businesses must manage their end-of-year tax liabilities independently.


The CIS tax deduction is calculated by subtracting the cost of materials from the gross amount, which gives a labour amount. Then, the contractor calculates the tax to deduct by applying the CIS tax rate to the labour amount. For example, if the gross amount is £700, the cost of materials is £200, and the CIS tax rate is 20%, the CIS tax deduction would be £100 (£500 * 20%).


In the UK's Construction Industry Scheme (CIS), the tax deductions are calculated before Value Added Tax (VAT) is applied. This is crucial for businesses operating within the construction sector. When a contractor pays a subcontractor for a job, the contractor is required to make a CIS deduction from the subcontractor's pay. This deduction is then passed on to HM Revenue and Customs (HMRC). The CIS deduction is calculated based on the subcontractor's pay excluding VAT. This means that the CIS deduction is made before VAT is added to the invoice.


A CIS tax accountant can provide invaluable assistance for businesses operating in the UK construction industry. From helping with CIS registration and calculating tax deductions, to preparing CIS returns and representing your business in disputes with HMRC, their expertise can help ensure your business remains compliant with CIS regulations and operates as tax-efficiently as possible.


Do Contractors Pay More Tax than Employees?

Well, let’s ask the numbers. Here’s a comprehensive table comparing the tax payments of contractors and employees in the UK:

Please note that these rates are based on the tax year 2023/24 and may vary depending on individual circumstances. The tax rates for contractors include both corporation tax and dividend tax. For employees, the rates include income tax and National Insurance Contributions (NICs).


It's clear from the table that contractors generally pay more tax than employees when their income exceeds £50,024. However, between £14,500 and £50,000, employees pay more tax. It's also important to note that contractors have additional costs such as running a company and accountancy fees, which can offset some of the tax advantages. Remember, this is a simplified comparison and individual circumstances can significantly affect the amount of tax paid.


Case Study: Tax Calculation and Payment for a UK Contractor in 2023-2024


In this hypothetical scenario, we follow the experiences of Emily Turner, a freelance IT consultant in London, navigating her tax obligations for the fiscal year 2023-2024. The case study is designed to provide a real-life example of tax calculations and strategic financial decisions affecting UK contractors.


Background

Emily has been a contractor operating through her limited company, Turner Tech Solutions Ltd. This fiscal year, her company has seen a revenue of £120,000 with allowable business expenses totaling £20,000.


Step-by-Step Tax Calculation and Payment Process

  1. Corporation Tax Calculation Emily's taxable profit for the year, after deducting business expenses from her revenue, stands at £100,000. For the 274 days of profits in the 2023-24 tax year, the profits are taxable at 19% due to her company's earnings being below £50,000. For the remaining 91 days, falling into the 2024-25 tax year, the rate remains at 19% as her profits continue to be under the threshold for higher rates.

  2. Dividend Distribution Emily opts to take a minimal salary of £12,570, the tax-efficient threshold for 2024-25, to maximize her dividend withdrawal while minimizing her personal tax liability. This strategy allows her to benefit from the lower tax rates on dividends compared to salary. The first £500 of her dividends are tax-free, and the subsequent amounts are taxed at 8.75% up to the basic rate band.

  3. Personal Income Tax Emily’s personal tax is minimized due to her strategic salary withdrawal at the tax threshold. She pays no income tax on her salary as it matches the personal allowance, and her dividend income is taxed at a significantly reduced rate compared to a higher salary withdrawal.

  4. National Insurance Contributions For Emily's salary level, she pays no employee National Insurance as it is below the Upper Earnings Limit. However, her company must pay employer’s NI contributions for the amount over the Lower Earnings Limit.

  5. Utilizing Tax Savings Measures She utilizes the ‘carry forward’ rule to maximize her pension contributions, allowing her to decrease her taxable income further and reduce her overall tax liability for the year.

  6. Filing and Payments Emily ensures her company’s tax returns are prepared and filed by the deadline using form CT600. Her personal self-assessment tax return is also submitted, calculating her tax due on dividends and salary.


This year, Emily has successfully navigated her tax responsibilities by combining effective business expense management with strategic salary and dividend distributions. Her approach not only ensures compliance with tax regulations but also maximizes her income retention by making savvy use of allowable tax reliefs and thresholds.
