What is IR35 and Why Does It Matter for Bid Consultants?
IR35 is a UK tax legislation that significantly impacts bid consultants, interim bid support professionals, and contractors who provide services through a personal service company (PSC) or other intermediary.
Designed to address “disguised employment,” IR35 determines whether you, as a bid consultant, are genuinely self-employed or should be classified as an employee for tax purposes.
Understanding IR35 is crucial for anyone in bid consultancy or interim roles, as it directly affects your tax obligations, income, and the way you manage your professional services.
