The issue

The IR35 status changes have led to many organisations becoming nervous around engaging with PSCs due to the risk of being inadvertently hit by a large and unexpected tax bill from HMRC. A few have even taken the draconian step of imposing “blanket bans”, refusing to engage with any PSCs under any circumstances.

The current approach

This approach, however, comes at a significant cost. Where a PSC is needlessly treated as Inside IR35, it can result in additional and avoidable costs, such as Employer’s NIC,
the Apprenticeship Levy, and potential claims for employment rights, depending on how a contractor is engaged. More importantly, it reduced access to some of the best contracting talent out there. These contractors are far more likely to be attracted to
end-hirers who adopt a robust and fair approach to determining IR35 status.

The advantage

Employers willing to engage with PSCs therefore stand to gain a significant competitive advantage and ability, particularly in a post-pandemic landscape where flexible workers are set to play an even greater role in the UK economy and access to the best talent will be decisive.

The Solution

The Kingsbridge IR35 Status Tool takes a best-of-both approach, allying a custom-designed automated process – developed by Andy Vessey ATT, ex-HMRC, tax advisor, and a leading IR35 specialist who has defended over 500 investigations, most of which he has won – with in-house expert consultancy to provide the quickest, most accurate IR35 status result available.

If it’s a clear-cut case, the tool then generates an instant determination, as well as a comprehensive report that pulls through the notable positives or negatives of a given engagement, as well as an official Status Determination Statement (SDS) that you can supply to the contractor. If it’s a borderline result, the answers given are passed over to one of Kingsbridge’s in-house IR35 specialists for further manual review.

Kingsbridge is currently the only IR35 status provider on the market to offer a hybrid solution, and we firmly believe that it’s the best one-stop-shop to meet all your IR35 business requirements.
