In order to manage your finances properly, it's worth asking an accountant. I use these accounting services. I have used Gorilla Accounting every month since March 2017, and in those 5 years they have been simply exceptional.
As a freelancer/contractor, they offer a comprehensive service for my tax proposals, handling VAT/corporate tax returns and personal tax returns as well as limited liability company duties such as confirmation of statements.
As part of your payment, you get access to a free agent, a fantastically convenient cloud-based accounting software that can connect to your bank.
