Setting up and registering a sole proprietorship
When setting up as a freelancer in Norway, you can refer to Altinn as a legitimate source of up-to-date information: https://www.altinn.no/en/start-and-run-business/
You will need to keep accounts (book-keeping obligation), although you may be exempt from this obligation if you run a small sole proprietorship which is not registered for VAT and has a turnover of less than NOK 50,000.
It is also possible to invoice and receive payment for your work without starting your own business. You can sign up with a company who will invoice and handle your tax and other financial obligations for you. Below are some links to companies who offer that service. PLEASE NOTE: Sandberg does not have experience of, nor recommend, any particular company, so it is your responsibility to research the options available and select one to suit your requirements.
If you decide to invoice this way, please check that the invoicing company you are using accepts payments from companies based in the UK.
