Accountancy for Limited Company Contractors


Setting up your own limited company and working as a contractor is very exciting. You’ll have more freedom and flexibility over when and how you work, and it is usually a very lucrative way of working.

However, there is a lot of admin and tax responsibility that goes into the set-up and management of a limited company, so you need to be sure you have a trusted accountant who can help you navigate through the complexity. At JSA, we’ve been providing clear, expert, and complaint accounting services to limited companies for over 30 years, so you can be sure you’re in safe hands.




Whether you’re ‘inside’ or ‘outside’ IR35, we provide a range of flexible solutions so you can keep working compliantly – in a way that suits you.
