Stop running the CEST tool. Nobody is determining IR35 for a shop that has not sold.
HMRC will let you run Check Employment Status for Tax this evening as if a determination is a business. You can tick substitution, control, and mutuality of obligation and save a PDF that says outside IR35. You have not taken a payment. You have not got a client who hired you. You are determining status for a shop that does not exist.
IR35 is an off-payroll rule for contractors who already work through a company for a client. A CEST result written against zero invoices is a status for a contract you have not earned. The tool is not your problem. The missing sale is.
Do this today:
Write down the client you would put on a status determination. If the list is empty, you do not have an IR35 question. You have a draft offer.
Take one payment as a person, not as a deemed employee. Put the customer's name and what they bought in a file you control. That is a sale. A CEST PDF with no engagement is not.
When you have ten paying customers and a medium-sized client who wants you inside a limited company, then run CEST. Until then HMRC has nothing to determine.
If you are running CEST because a LinkedIn thread said contractors get caught, you are solving a fear, not a business. A determination does not invoice. A customer does.
What status are you checking that has not made you a pound?
