These changes do not affect whether you can work through your own limited company, generally known as a ‘personal service company’, or ‘PSC’. This will still be possible, however the way the Income Tax and NICs are calculated and paid may change for some contractors, or some clients may change the way they wish to engage you and other contractors. If you are changing the way you work and will no longer be working through your own limited company, you may need to consider what to do with your company (for example, you may want to close it down). If you are thinking of working through an umbrella company, we have published guidance to help you understand what this means in practice.
