There is constant small supply of news that comes out every year regarding IR35. Although there have been no significant updates recently, its still good to have an awareness of IR35, and what your options are. So, think of our blog today as your regular IR35 refresher.
IR35 determines whether your freelance income is treated like employment income, which can have a big impact on your take-home pay. In this article, we’ll break down what IR35 means, how to figure out where you stand, and what steps you can take to stay on the right side of the rules.
Key Takeaways
- IR35 determines whether your freelance income is taxed like employment income or business income, which can have a big impact on your take-home pay.
- To work out your IR35 status, you need to consider factors like control, the right of substitution, and mutuality of obligation—regular contract reviews are key to staying compliant.
- The small company exemption gives freelancers more flexibility in managing their tax affairs, and upcoming changes to IR35 aim to tackle double taxation and create a fairer system.
Understanding IR35 and Its Impact on Freelancers

IR35 is a piece of UK tax legislation designed to tackle tax avoidance by individuals who provide services through an intermediary, such as a personal service company, but who would otherwise be considered employees if the intermediary didn’t exist. The primary goal is to ensure independent contractors pay the appropriate taxes and do not unfairly benefit from tax advantages meant for the self-employed. The legislation focuses on disguised employment, where a freelancer’s working arrangements closely resemble those of an employee.
The impact on freelancers is significant. IR35 rules determine whether a contractor’s income is taxed as employment income or business income. If a contract falls inside IR35, the contractor is taxed as an employee, paying income tax and National Insurance contributions via PAYE, alongside employment taxes. If a contract is outside IR35, the contractor retains responsibility for their tax payments as a self-employed individual. This classification is crucial, as it directly affects take-home pay and overall compliance with tax law.
The financial impact of IR35 can be substantial. Being classified as inside IR35 can reduce a freelancer’s take-home pay by up to 30-33%, depending on their contract and day rate. This is because contractors inside IR35 pay the same income tax and National Insurance as an employee but do not receive employment benefits like sick pay or annual leave. Understanding your IR35 status is essential, as it influences financial risk, tax planning, and overall business strategy.
Beyond tax purposes, IR35 also affects how freelancers structure their working practices, negotiate contracts, and manage their business. Keeping up to date with IR35 rules and regularly reviewing your employment status can help protect your financial position and ensure long-term business sustainability.

Determining Your IR35 Status

Assessing your IR35 status requires careful consideration of several key factors. One of the biggest indicators is the level of control your client has over your working arrangements. If the client dictates how, when, and where you complete the services, it suggests an employment relationship, placing you inside IR35. However, if you have autonomy over your working practices, including when and how the work is done, it strengthens the case for being outside IR35.
Another crucial factor is the right of substitution—the ability to send a qualified substitute to carry out the contracted services. If your contract allows for substitution and your client accepts it without restriction, this indicates an outside IR35 status. However, this right must be genuine—if it exists only on paper but is never exercised, it may not hold weight. For full validity, the client should allow and pay the substitute directly, reinforcing your status as an independent contractor.
A further consideration is mutuality of obligation (MOO)—the expectation that the client will continue to provide work and that you are obliged to accept work. If such an expectation exists, it points towards an employment relationship, which can indicate an inside IR35 status.
To formalise an IR35 status decision, the Status Determination Statement (SDS) is issued by the end client. This document outlines the reasoning behind the employment status determination and is crucial for both freelancers and clients to understand. Whether you engage directly or through an umbrella company or limited company, the SDS plays a pivotal role in defining your tax obligations under the off payroll working rules.
Regularly reviewing your contracts and working arrangements is essential to ensure they align with your actual working practices. Proactively managing your IR35 status helps avoid incorrect classification and ensures you are paying the appropriate taxes while maintaining compliance with IR35 rules.
Small Company Exemption and Overseas Clients
The small limited company exemption provides significant relief for many contractors under the off payroll working rules. To qualify, a limited company must meet at least two of the following criteria for two consecutive financial years:
- An annual turnover of no more than £10.2 million
- A balance sheet total under £5.1 million
- An average of 50 or fewer employees
This exemption shifts the responsibility of determining IR35 status from the end client to the contractor, offering greater flexibility in managing tax affairs and ensuring compliance with tax legislation.
When working with overseas clients, the situation becomes more nuanced. If an overseas client does not have a permanent UK establishment, the contractor is responsible for determining their IR35 status. This presents both an opportunity and a financial risk, allowing contractors to manage their status independently while ensuring they pay the appropriate taxes.
The advantages of the small business exemption are clear. It reduces the likelihood of being incorrectly classified as inside IR35 by an end client, giving contractors more control over their tax and national insurance obligations. This is particularly beneficial for freelancers who can demonstrate their self-employed status through well-structured contracts and working arrangements.
For contractors engaging with overseas clients, it’s essential to understand how IR35 rules apply. While the rules apply regardless of location, an overseas client without a UK presence is not responsible for determining employment status under IR35 rules. This can simplify compliance for experienced contractors working internationally, offering additional flexibility for those navigating complex tax law across multiple jurisdictions.
Best Practices to Stay Outside IR35

A strategic approach to working arrangements and contract terms is essential for maintaining outside IR35 status. Key indicators that demonstrate you are a genuinely independent contractor include:
- Control over your work schedule
- The ability to send a substitute
- Using your own equipment
- Bearing financial risk
These factors signal that you are self-employed rather than engaged in disguised employment under the off payroll working rules.
Reviewing Contracts and Working Arrangements
Conducting a comprehensive contract review is crucial. Your contract terms must align with your actual working practices. For example, ensure that a substitution clause is not just included but also a viable option in practice. Documenting control and direction within your contracts strengthens your outside IR35 status. Regularly reviewing and updating your contracts to reflect changes in working arrangements helps maintain compliance with IR35 rules.
Demonstrating Financial Risk
Taking on financial risk reinforces your self-employed status. You can demonstrate this by:
- Working with multiple clients rather than relying on a single end client
- Handling multiple contracts or projects at the same time
- Correcting mistakes at your own expense
- Investing in and using your own equipment
- Paying for your own training
These practices establish that you are not economically dependent on a single client, helping to differentiate your status from that of a permanent employee.
Navigating Client Expectations
If a client insists on hiring only inside IR35 contractors, you have several options:
- Consider becoming a permanent employee, which provides job security and employment benefits but reduces autonomy.
- Work through an umbrella company, which simplifies tax payments and compliance but reduces flexibility.
- Explore new client opportunities that allow you to operate outside IR35.
- Negotiate contract terms to ensure that your employment status reflects self-employment rather than an employment contract.
By proactively managing your IR35 status and structuring your working arrangements correctly, you can maintain tax advantages, retain control over your business, and operate as a genuinely independent contractor.
IR35 In The News Recently

IR35 has been making waves again, with recent cases highlighting key issues around tax compliance, employment status, and the responsibilities of agencies and contractors alike. Here’s a look at some of the latest developments:
Tribunal Ruling on Employer NI Deductions for Inside IR35 Workers
A landmark employment tribunal ruling in M Appiah v Tripod Partners resulted in a £37,000 payout to a contractor after an agency was found to have wrongly deducted employer’s National Insurance (NI) from their pay. The ruling was based on the fact that the contractor was classified as a ‘worker,’ meaning employer NI could not legally be deducted from their earnings.
While the ruling has led to speculation that other contractors may now seek similar claims, legal experts suggest the case is highly fact-specific and may not set a widespread precedent. Tripod Partners is also expected to appeal, which could alter the final outcome.
For agencies, the key lesson here is clear: employer NI is their responsibility, not the contractor’s. Ensuring contracts are structured correctly from the outset can prevent disputes and unnecessary liabilities down the line.
Gary Lineker’s IR35 Settlement with HMRC
Following a seven-year legal battle over his tax status, football pundit Gary Lineker has reached an out-of-court settlement with HMRC. Originally, HMRC was pursuing £4.6 million in tax and National Insurance, but experts believe the final settlement was significantly lower.
This case has raised questions about HMRC’s approach to high-profile IR35 disputes. Some tax specialists argue that the case was a costly and unnecessary pursuit, particularly given that the tribunal had already ruled in Lineker’s favour once before. Others suggest that HMRC may have been swayed more by Lineker’s public profile than by the actual strength of their case.
For contractors, the lesson here is that long-running IR35 disputes can be incredibly stressful and expensive. While settlements are sometimes an option, having watertight contracts and seeking expert tax advice early on remains the best defence against unwanted tax scrutiny.
Bryan Robson’s IR35 Case: A Pyrrhic Victory for HMRC?
The IR35 case involving former footballer Bryan Robson and his company, Bryan Robson Limited, resulted in a mixed outcome. HMRC initially claimed that Robson’s work as a global ambassador for Manchester United should have been taxed under IR35, but they conceded that contracts prior to December 2019 were not within scope. This significantly reduced the potential tax liability.
A key point in the case was that part of Robson’s earnings were attributed to ‘image rights,’ which are not subject to IR35. This further reduced the tax at stake, meaning HMRC’s eventual “win” was only a fraction of their original claim.
With the tribunal questioning why HMRC didn’t settle the case much earlier, this case reinforces the importance of having well-drafted contracts that reflect the reality of working arrangements. It also highlights concerns over whether HMRC’s aggressive approach to IR35 litigation is always justified, particularly when the cost of enforcement exceeds the tax recovered.
Consequences of Being Inside IR35
Being classified inside IR35 brings several financial consequences. Contractors inside IR35 must pay income tax and National Insurance contributions, similar to employees, and thus face the same income tax implications. This results in a significant reduction in take-home pay, potentially by as much as 30-33%, depending on the contractor’s day rate. This reduction significantly impacts a freelancer’s financial well-being and overall profitability.
Despite similar contributions to employees, contractors inside IR35 lack employment rights like sick pay or annual leave. This absence of benefits worsens financial strain as contractors manage finances without the safety net provided to regular employees, especially in the context of off payroll working rules.
The impact of being inside IR35 extends beyond immediate financial implications. It impacts long-term financial planning, savings, and investment strategies. Contractors must navigate these challenges while ensuring IR35 compliance, which can be an ongoing administrative burden.

Summary
Navigating IR35 rules is essential for freelancers and independent contractors who want to manage their tax status effectively and maximise their take-home pay. Understanding the key factors that determine IR35 status, such as control, substitution rights, and mutuality of obligation, is crucial for staying outside IR35 and ensuring compliance with tax legislation.
The small limited company exemption provides greater flexibility for contractors, shifting the responsibility of determining IR35 status from the end client to the contractor. Similarly, working with overseas clients without a UK establishment can offer more control over employment status while still requiring careful attention to tax payments and compliance with off payroll working rules.
To maintain outside IR35 status, contractors should focus on structuring their contracts and working arrangements to reflect genuine self-employment. This includes demonstrating financial risk, working for multiple clients, using own equipment, and ensuring that contract terms align with actual working practices. Regularly reviewing and updating contracts is vital to avoid being misclassified and to ensure alignment with IR35 rules.
For those facing clients unwilling to engage outside IR35 contractors, alternative options include umbrella companies or considering permanent employment, each with its own trade-offs between tax advantages, job security, and flexibility.
Ultimately, staying compliant with IR35 rules while maintaining control over your business requires proactive management, regular contract reviews, and a strategic approach to employment status. By understanding the rules apply and taking the right steps, freelancers can navigate IR35 confidently and protect their financial future.
