Can I reduce the risk of IR35 applying?
It is possible to review working arrangements for contractors before the new rules come into effect. This will require immediate action.
You could consider terminating current contracts and entering into new terms that reflect working arrangements for a self-employment arrangement.
Another possibility is encouraging contractors to abandon the PSC model and provide services under a compliant umbrella company.
In the event of a determination of employed status you should seek to enter new terms that at the very least reflect the new tax arrangements .
