How Consultancy Agreements Can Affect Your IR35 Status
For contractors and businesses across the UK, understanding IR35 is essential. The off payroll working rules are designed to determine whether a contractor is genuinely self employed or should be treated as an employee for tax purposes. While many factors influence an IR35 assessment, one of the most important is the consultancy agreement between the contractor and the client.
A consultancy agreement sets out the working relationship, responsibilities and expectations of both parties. If the agreement does not accurately reflect the actual working practices or contains clauses that suggest an employment relationship, it could affect a contractor's IR35 status.
The Infinity Group provides professional payroll, tax and IR35 advisory services, helping contractors and businesses understand consultancy agreements and reduce compliance risks. This guide explains how consultancy agreements can influence IR35 status and what businesses should consider when preparing contracts.
What Is IR35?35 status
IR35 refers to UK tax legislation that aims to prevent disguised employment.
The rules apply when a contractor provides services through an intermediary, such as a personal service company, but would be regarded as an employee if the intermediary did not exist.
If a contract falls inside IR35, the contractor is generally required to pay Income Tax and National Insurance in a similar way to an employee.
If the contract falls outside IR35, the contractor is usually treated as genuinely self employed for tax purposes.
The Infinity Group helps businesses and contractors understand these rules and make informed decisions about compliance.
What Is a Consultancy Agreement?
A consultancy agreement is a legal contract that defines the relationship between a contractor or consultant and a client.
It usually outlines:
- The services to be provided
- Payment arrangements
- Project duration
- Responsibilities of each party
- Confidentiality obligations
- Termination conditions
- Intellectual property provisions
A well drafted consultancy agreement should accurately reflect how the contractor will work in practice.
The Infinity Group assists businesses in reviewing consultancy agreements to help support compliance with IR35 legislation.
Why Consultancy Agreements Matter for IR35
HMRC considers both the written contract and the actual working relationship when determining IR35 status.
A consultancy agreement that resembles an employment contract may increase the likelihood of a contract being considered inside IR35.
Conversely, a properly drafted agreement that reflects an independent business relationship may support an outside IR35 assessment.
The Infinity Group helps clients understand how contractual terms can influence IR35 decisions while ensuring agreements remain commercially appropriate.
The Importance of Genuine Working Practices
A consultancy agreement alone does not determine IR35 status.
HMRC also looks at how the contract operates in reality.
For example, if a contract states that the contractor has independence but, in practice, the client exercises extensive control over the work, HMRC may place greater weight on the actual working arrangements.
Businesses should ensure that written agreements and day to day practices remain consistent.
The Infinity Group advises clients on aligning contracts with genuine working relationships.
Control
One of the most significant IR35 factors is control.
HMRC considers:
- Who decides how the work is completed
- Who controls working hours
- Who determines the working location
- Who supervises the contractor
A consultancy agreement that gives the client extensive control over these matters may indicate employment.
An agreement that allows the contractor greater independence may support self employment, provided the working practices reflect the contract.
The Infinity Group helps businesses understand how control clauses may affect IR35 assessments.
Right of Substitution
The right of substitution is another important consideration.
A genuine right of substitution means the contractor can provide a suitably qualified substitute to complete the work, subject to reasonable contractual requirements.
If the contractor must perform the work personally in every circumstance, HMRC may view this as being more consistent with employment.
Any substitution clause should be realistic, practical and reflected in the actual working relationship.
The Infinity Group reviews consultancy agreements to ensure important contractual provisions are clearly drafted.
Mutuality of Obligation
Mutuality of obligation refers to whether:
- The client is obliged to provide ongoing work.
- The contractor is obliged to accept future work.
Employment relationships often involve continuing obligations on both parties.
Independent consultancy arrangements are generally project based, with no guarantee of future work once the agreed services have been completed.
The Infinity Group provides guidance on structuring consultancy agreements that accurately reflect commercial arrangements.
Financial Risk
Independent contractors often accept greater financial risk than employees.
Examples include:
- Correcting defective work at their own expense
- Purchasing business equipment
- Maintaining professional insurance
- Managing business expenses
Where appropriate, consultancy agreements should accurately reflect these commercial responsibilities.
The Infinity Group helps contractors understand how financial risk can influence IR35 assessments.
Provision of Equipment
The equipment used to complete work may also be relevant.
Contractors who provide and maintain their own specialist equipment may appear more like independent businesses than employees.
However, the significance of this factor depends on the nature of the work being undertaken.
The Infinity Group provides practical advice based on each client's individual circumstances.
Integration Into the Client's Business
HMRC may consider whether the contractor is integrated into the client's organisation.
Factors that could suggest employment include:
- Managing employees
- Receiving employee benefits
- Appearing on internal organisation charts
- Participating in staff management activities
A consultancy agreement should clearly distinguish the contractor's independent role.
The Infinity Group helps businesses review working arrangements to reduce unnecessary compliance risks.
Reviewing Consultancy Agreements Regularly
Business requirements often change during long term projects.
Consultancy agreements should therefore be reviewed periodically to ensure they continue to reflect actual working practices.
Regular reviews help identify:
- Outdated contractual terms
- Changes in responsibilities
- New compliance risks
- Opportunities for improvement
The Infinity Group supports businesses by reviewing consultancy agreements as projects evolve.
