What's happening?
IR35 reforms came into place on 6th April 2021. They mean your end hirer (unless they’re small) is now 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 may need to consider Umbrella employment or explore our IR35 Switch option.
Even if you don’t need to move to Umbrella employment right away, sign-up today to ensure you’re fully prepared and we’ll delay your Umbrella employment until your contract date (meaning you won’t pay a penny until then)!
We understand it can be very confusing. But don’t worry, our experienced contractor accountants are here to help with
IR35 Complete™ by JSA.

How we calculate the earnings
The calculation uses a 1250L tax code and Class 1 National Insurance.
The calculation assumes no additional income other than that included above. It is purely for information purposes and is therefore only a representation.
Expenses are claimable at the year-end via a P87 or personal tax return.
Based upon working 48 weeks across the year
JSA cannot accept responsibility for action taken solely on the basis of this income forecast.

Your IR35 Assessment
If you want to find out where you stand, we can help you complete a fair assessment for free.
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 IR35 Switch solution.
