Self-assessment income

I am self-employed, but I have a contract with a company that provides me with a place and clients. They give me a job, but I transfer to the company a percentage of the amount I received from clients after each day of work. Should I record this amount as income and then as expense, or does the contract already imply that this amount is not my income, but the company's?

Hi Anna16,
Yes, it's your income and then an expense.
Thank you.
