While multiple or concurrent contracts are certainly a positive indication that you are a ‘genuine’ business, each engagement will still be considered individually. In theory, you could be working on two separate contracts at the same time and one could be inside IR35 and the other outside. If you do have multiple contracts with different clients, you must still ensure that both the contracts and working practices are compliant. Remember, IR35 status is not established by any one factor. Instead think of it as a multitude of factors working together to indicate IR35 status.
