IR35 and each engagement
For public-sector and medium or large private-sector clients, the client decides whether the off-payroll rules apply and must issue a Status Determination Statement. For small private-sector clients, your own company decides. Keep contracts, statements of work and evidence of how the engagement operates in practice, including substitution and control.
Inside-IR35 income has tax and National Insurance deducted by the fee-payer. Your company records it so that the same income is not taxed again.
