Remember though - in salaried status you have a guaranteed income, study leave, sick leave etc and other benefits an employee has. As a partner you will take what comes, what is "left over" from running the business and over the last two years that has meant less and less. You won't have guaranteed study leave, you will pay for locums when you are off ill (until sickness insurance kicks in which will depend on your cover) and you have all the worries of running a business entails. There are pro's and cons.
But make no mistake, this government, previous ones and successive ones, will want rid of self employed status - they want to be in control, or hand it over to a multinational. We'll all be wearing logos on our shirts......
