What's happening?

In April 2021, reforms to (off-payroll) IR35 reforms in the private sector will be implemented. They will mean your end hirer (unless they’re small) will be responsible for assessing your assignment status – ‘inside’ or ‘outside’ IR35 – and issuing a Status Determination Statement to you and your agency. If you receive an ‘outside’ SDS, you may be able to continue working through your PSC. But if your assignment is ‘inside’, you’ll need to review your working options.

We understand it can be very confusing. But don’t worry, our experienced contractor accountants are here to help with
IR35 Complete™ by JSA.

Your IR35 Assessment

If you want to find out where you stand before April 2021, we can help you complete a fair assessment for free. 

The earlier you’re assessed for IR35 compliance, the more prepared you’ll be when the reforms come into place. We have years of experience in contractor compliance, so we can help you get assessed reliably and fairly with our IR35 Complete™ Assessment Tool.

After your assessment, if you’re ‘inside’ IR35 but want to continue working through your PSC, we can help you alter your contracts and working practices where appropriate so that you can operate ‘outside’ IR35 as much as possible. Or, where this isn’t feasible, we’ll set you up with our Umbrella toggle solution.

Painless and jargon free

A big thanks to Darris Thomas for taking me through the process of creating a limited company and making it painless and jargon free. He was personable, knowledgeable and didn’t mind me asking noddy questions! Excellent customer service. Cheers Darris.
