What is the IR35 App?

The IR35 App has been designed as a paperless tool for businesses caught within Off Payroll Working. It helps navigate and demonstrate compliance with the complex rules governing IR35.

It guides you through the factors you need to consider with every engagement. It then produces an assessment status indicator and the appropriate documentation to support and demonstrate the decision-making process.

What is different about the IR35 App?

Unlike tools available elsewhere, the documents produced by the IR35 App provide bespoke supporting evidence of the working relationship specific to each engagement. This evidence also links to the decision provided by the HMRC Check Employment Status Tool (CEST).

The combination of the IR35 App output and CEST decision provides your business with the strongest possible defence against any contract challenges by HMRC.

Incorrect decisions about deemed employment status are ultimately your responsibility. Mistakes can be costly, both financially and reputationally. The IR35 App is an essential tool to help protect your business and give you peace of mind.

The IR35 App is more than a simple, ‘off the page’ solution. By dealing with us in person, you know that you are getting individual and expert support to help you overcome the complexities of IR35.
