The new IR35 regulations came into effect from the 6th April 2021. These mean that if you work through a personal service company (PSC), you’ll need a Status Determination Statement (SDS) for every engagement with medium-sized and large clients in the private sector and, if work is deemed to fall inside IR35, you’ll need to pay tax at source via an umbrella company. This is the same for clients in the public sector. You are welcome to work with your choice of umbrella partner, as long as they are FCSA-accredited.
