2026/27 rates. "Outside IR35" assumes you run your own personal service company (PSC) and take a fixed salary plus dividends. "Inside IR35" assumes umbrella employment, since the end client or agency deducts PAYE tax and NI as if you were their employee. Real umbrella margins vary (£20–£30/week is typical); real PSC costs include accountancy fees (not shown here) and insurance. This does not determine your IR35 status — that depends on your actual working practices. Guidance only — not tax or employment-status advice.
Figures use published 2026/27 UK tax rates and are simplified estimates for guidance only — not tax, accountancy, or financial advice. Your actual liability depends on your full circumstances; confirm withGOV.UK or a qualified accountant before acting.
