What to know before you decide
Choose a structure after modelling the whole picture
Your expected turnover, costs, retained profit and personal cash needs affect whether a company is suitable. Contract status, VAT and pension access can also change the comparison. Allow for administrative costs and professional rules before incorporating; a lower headline tax rate does not prove a better overall outcome.
Separate the clinical launch from the tax setup
Tax registration and bookkeeping are only part of opening a practice. Professional indemnity, clinical registration, patient information and premises arrangements need their own advisers and checks. For accounting, establish who contracts with the patient, who collects fees, how deposits are recorded and what evidence you retain for business costs. A short forecast should show when the practice can support drawings without consuming tax reserves.
