Can I Challenge my IR35 Status and SDS? Yes. All contractors are entitled to challenge an end hirers IR35 determination. To do this, they need to undertake an independent review and put forward additional supporting evidence.
Who is the Fee Payer or Deemed Employer? If you are inside IR35, your ‘fee payer’ is the party above your Limited Company (PSC) who is responsible for deducting national insurance and tax before paying you net earnings.
