Hiring contractors can streamline your business, but navigating UK contractor payments means understanding tax rules, legal requirements, and IR35 compliance.
Are you sure you're doing it right? This guide covers everything from invoicing to staying compliant.
- In the UK, contractors are independent professionals offering services directly to your business, managing their own taxes, and working with multiple clients.
- Subcontractors, however, are often hired by contractors to handle specific tasks, like electrical or plumbing work in construction. Get clear on the differences and ensure your contractor payments are handled the right way!
What Defines a Contractor?
A contractor is a person or business providing services under a commercial agreement, not as an employee. They work independently, manage their own business, handle taxes, and control how and when they complete tasks.
Key traits of genuine contractors include:
- Business Independence: They manage their own business and work with multiple clients.
- Financial Responsibility: They assume the cost of any mistakes or delays.
- Autonomy in Work: They determine how tasks are completed, as long as they meet agreed-upon guidelines.
- Use of Own Equipment: They supply their own tools and resources.
- Right to Substitute: They have the option to delegate the work to someone else, provided you approve.
Understanding IR35: The Off-Payroll Working Rules
IR35, also known as the off-payroll working rules, governs how contractor payments are taxed, ensuring they align with employment income when applicable. These rules aim to prevent "disguised employment," where individuals operate as contractors through a company to lower their tax liabilities, despite working like employees.
For business owners, IR35 introduces a critical obligation: you must determine whether each contractor falls "inside" or "outside" IR35 and ensure compliance before processing payments.
How to Navigate IR35 as a Business Owner
The assessment process examines the working relationship through three key factors:
Right of Substitution: Does the contractor have the ability to send someone else to complete the work, and would you accept this substitute? If so, it indicates they are likely outside IR35.
Mutuality of Obligation: Is there an obligation for you to provide work and for the contractor to accept it? A genuine contractor relationship is limited to the terms of the current contract without ongoing commitments.
Control: Who determines how, when, and where the work is performed? The more control you exert over these aspects, the higher the likelihood the contractor falls inside IR35.
What are the Three Key Rules of IR35?
Understanding these three fundamental IR35 rules will help you make accurate determinations:
1. The Substitution Test: A Key Indicator for IR35
A genuine right of substitution is a strong indicator of an outside IR35 relationship. If a contractor can send a substitute to complete the work—and you are willing to accept that substitute—this demonstrates independence. However, the substitution right must be genuine and practical, not merely theoretical.
2. The Control Assessment
Evaluate who determines the tasks to be performed, as well as how, when, and where they are completed. The greater the level of control you exert, the more the relationship mirrors that of traditional employment.
3. The Mutuality of Obligation Review
In true contractor relationships, there is no commitment to offer future work, nor any obligation for the contractor to accept it. Each project is treated as an independent agreement.
Essentials for Paying Contractors
When paying contractors as a business owner, several key elements ensure compliance and smooth operations.
Determine IR35 Status First
Prior to making any payments, ensure you complete an IR35 assessment. It’s essential to document your decision-making process, as HMRC may require evidence to support how you arrived at your conclusion.
Set Up Proper Contracts
Craft contracts that accurately define your working relationship. Be sure to include essential terms such as:
- Payment rates and schedules
- Project deliverables with clear deadlines
- Ownership of intellectual property
- Termination conditions and procedures
- Right of substitution, if applicable
A well-structured contract ensures clarity and sets the foundation for a professional and transparent partnership.
Establish Payment Processes
For Contractors Outside IR35: Pay the full invoice amount without making deductions for tax or National Insurance. The contractor is responsible for managing their own tax obligations.
For Contractors Inside IR35: Process payments through PAYE, deducting income tax and National Insurance contributions, similar to how you would handle payments for employees.

Maintain Accurate Records
Maintain comprehensive records of the following:
- IR35 status determinations along with supporting documentation
- All payments issued to contractors
- Contracts, including any amendments or variations
- Communications regarding working arrangements
How Contractors Can Invoice You
Understanding different invoicing methods helps you manage contractor payments effectively.
Standard Business Invoices
Outside IR35 contractors typically issue standard business invoices that include the following details:
- The contractor’s business name and contact information
- Your company’s details
- An invoice number and date
- A clear description of the services provided
- Payment terms
- VAT information (if applicable)
These elements ensure clarity and professionalism while streamlining the payment process.
Monthly or Milestone-Based Invoicing
Contractors often favor consistent payment schedules to streamline their work:
- Monthly invoicing is ideal for ongoing services, ensuring predictable cash flow.
- Milestone-based payments work best for projects with defined deliverables, tying payments to progress.
- Time-based invoicing is a standard choice for consultancy work, aligning payments with hours worked.
Digital Invoicing Solutions
Today’s contractors increasingly rely on digital invoicing platforms that seamlessly integrate with accounting systems, streamlining the payment process for greater efficiency.
Managing Inside IR35 Situations
If a contractor falls within IR35, you are required to take the following steps:
- Operate PAYE: Register the contractor under PAYE to deduct income tax and National Insurance contributions.
- Issue payslips: Provide monthly Payslips detailing all deductions.
- Address pension obligations: Assess and comply with auto-enrolment pension requirements, if applicable.
- Maintain employment records: Keep thorough records, just as you would for regular employees.
