How ir35 reforms affect uk contractors in 2024
IR35 reforms are set to impact UK contractors significantly in 2024, increasing HMRC scrutiny, clarifying status determination, shifting liability, and imposing stricter penalties, affecting contractors’ financial situations and work arrangements.

Understanding IR35 Reforms: Impact on UK Contractors in 2024
The IR35 reforms have been a subject of ongoing debate in the UK, and as we approach 2024, the impact of these changes on contractors remains a crucial topic. The reforms, designed to tackle tax avoidance by ‘disguised employees’, have shifted the landscape for independent contractors, freelancers, and the businesses that hire them. With new changes expected in 2024, it’s essential to understand what these reforms mean and how they will affect the contracting industry in the UK.
What is IR35?
IR35, also known as the "off-payroll working rules," was introduced by HMRC in 2000. The legislation aims to ensure that contractors who work in a manner similar to regular employees but bill their services through an intermediary, such as a personal service company (PSC), pay the appropriate amount of tax. The rules essentially differentiate between contractors who are genuinely self-employed and those who are ‘disguised employees’—individuals who are contractors in name but function as full-time employees in practice.
Under IR35, if a contractor is deemed to be working as a ‘disguised employee,’ they are required to pay income tax and National Insurance contributions (NICs) at the same rate as an employee, despite not receiving the benefits of full-time employment, such as holiday pay or sick leave.
IR35 Reforms: A Brief History
The most significant change to IR35 came in 2017 for the public sector and in 2021 for the private sector. Prior to these reforms, it was the responsibility of contractors themselves to determine their employment status and whether IR35 applied to their contracts. However, under the new rules, this responsibility was shifted to the end client, i.e., the company hiring the contractor.
This change meant that medium and large businesses became responsible for determining the IR35 status of contractors they engaged. If the contractor was deemed to be inside IR35, the hiring company had to deduct income tax and NICs before making payments. Small businesses were exempt from this responsibility, allowing contractors working with them to continue determining their IR35 status.
Key Changes Expected in 2024
While the core principles of IR35 are not expected to change drastically in 2024, there are anticipated amendments that could impact how the legislation is enforced and interpreted. These changes aim to tighten compliance and reduce tax avoidance further, while also addressing some of the criticisms levelled at the current system.
Increased HMRC Scrutiny
One of the key changes expected in 2024 is an increase in HMRC investigations into contractors and companies that engage them. The government has signalled its intention to ramp up enforcement efforts, particularly targeting industries where non-compliance is suspected to be high. This could lead to more contractors being assessed as inside IR35, even in cases where they may have previously been deemed outside IR35.Clarification of Status Determination
Another expected reform is the introduction of clearer guidelines for determining employment status under IR35. There has been widespread confusion and inconsistencies in how businesses apply the rules, often leading to disputes between contractors and their clients. In 2024, the government is expected to issue more detailed criteria to help businesses make accurate status determinations, reducing the risk of misclassification.Liability Shifts
One potential change could involve a shift in liability when it comes to IR35 compliance. Currently, the end client is responsible for ensuring the correct determination of a contractor’s status. However, there have been discussions about making the supply chain more accountable. This could mean that recruitment agencies or other intermediaries could bear more responsibility for ensuring IR35 compliance.Increased Penalties for Non-Compliance
As part of the government’s drive to combat tax avoidance, there may be harsher penalties for businesses and contractors found to be non-compliant with IR35. While penalties already exist, they could be further increased to act as a stronger deterrent against tax avoidance.
The Impact on Contractors
The IR35 reforms have had a profound impact on contractors since their introduction, and the changes in 2024 are likely to exacerbate some of the challenges contractors face. Many contractors have already reported difficulties in securing contracts due to companies’ reluctance to engage with individuals deemed to be inside IR35. Some companies have implemented blanket bans on hiring contractors through PSCs, preferring instead to hire them on a PAYE basis or through umbrella companies.
Financial Implications
For contractors working inside IR35, the financial implications can be significant. Being deemed inside IR35 means that contractors lose the tax advantages associated with operating through a limited company, such as paying themselves through dividends. Instead, they are subject to PAYE tax and NICs, which can reduce their take-home pay by as much as 25-30%.
Impact on Flexibility and Contracting Culture
The reforms have also led to a shift in the contracting culture in the UK. Many contractors have found themselves pushed into permanent roles or forced to work through umbrella companies, which offer less flexibility and control. This shift could continue in 2024, as businesses seek to mitigate their risk by avoiding the complexities of IR35 altogether.
How Can Contractors Prepare?
With the changes expected in 2024, it is crucial for contractors to take proactive steps to protect themselves and their businesses. Here are a few strategies to consider:
Seek Professional Advice
Contractors should seek advice from tax specialists or legal professionals to ensure they understand their IR35 status and the potential impact of the reforms. This will help them make informed decisions and avoid costly mistakes.Review Contracts Carefully
Contractors should ensure that their contracts accurately reflect the nature of their working relationship with clients. This includes ensuring that the contract outlines genuine self-employed status, with a clear focus on autonomy and control over work.Work with Small Businesses
Since small businesses are exempt from the responsibility of determining IR35 status, contractors may find it beneficial to work with smaller clients to retain more control over their tax arrangements.
Conclusion
The IR35 reforms set to come into effect in 2024 will likely tighten the rules surrounding off-payroll working and increase scrutiny on contractors and businesses alike. While the full details of the changes are still to be confirmed, it is clear that contractors need to stay informed and take proactive steps to protect their financial interests. By understanding the reforms and preparing accordingly, contractors can navigate the evolving landscape and continue to thrive in the UK’s contracting industry.
