Our IR35 Solutions

We have a range of IR35 solutions to cater for your unique requirements.

IR35 Workforce data capture


It can be really difficult to identify all of your off-payroll workers; including what type of pay model, where they’re based and who’s supplying them.

Using our 18 years’ experience in providing flexible workforce solutions, we can provide a full service to identify your total off-payroll worker population and review your current processes.

This raw data will be the bedrock of shaping your strategies for IR35 compliance.


Flexible workforce solutions


Looking for a simple strategy to outsource the IR35 impact and risk of your off-payroll workforce, both now and in the future?

Take a look at our Flexible Workforce Solutions, which cover the end-to-end IR35-compliant workflow management, supply chain management, sourcing, pay & bill, reporting and compliance of your flexible workforce.

IR35 Workforce analysis and assessment


To complement the raw workforce data, companies will need to review and assess each assignment to understand the implications, including assignments which are in scope of the IR35 legislation.

We can offer an audit and analysis service to do this hard work for you, helping you understand the level of risk you’re exposed to and what solutions you may need to deploy to get ready.

Statement of work IR35 solution


If one or more of your company’s assignments within scope of IR35 can be easily defined as a deliverable, outcome-based piece of work, why not manage them under a statement of work contract?

Our engineering & technology services provider, Gattaca Projects, can deliver cost-effective, IR35-compliant project services, by offering specialists to operate under a statement of work with defined project deliverables.



Want to gain visibility of your contingent workforce and its compliance whilst retaining control over sourcing and supply chain management?

Our Payroll Services have been established for over 15 years and are utilised by numerous customers to bring efficiency, compliance and visibility over their payrolled/direct contractors and the process to pay them.

The solution will provide visibility and reporting of your contractors, whilst reducing future tax risk and providing greater cost control.

Full recruitment process outsourcing RPO


Once you’ve defined your strategies, there’s a good chance that at least some of your current off-payroll workforce will either need to transition to, or be replaced by, a permanent position.

If so, our Permanent Workforce Solutions can help you shape the strategy, communications plan and management of any recruitment, to ensure a smooth transition with no impact on your business.

Just getting ready for IR35 takes a lot of time and effort away from ongoing critical projects, and many of our clients are recognising that they neither have the time nor the desire to manage the IR35 changes on their own.

Gattaca’s end-to-end IR35 Change Management & Readiness solution can take away the hassle of preparing your business for the Private Sector reforms and even help you turn it into a positive for your business.

Our comprehensive solution includes dedicated project management, communications planning, and pre-agreed fixed costs, to get you ready with less time, effort and risk.
