Is conjoint collaborateur right for us?

I set up my own auto-entrepreneur business for english teaching a year ago with my husband as conjoint collaborateur on the basis that he runs my website and is my fixer of all things technical. Not having access to your excellent website and thinking I understood this term I didn’t appreciate that there was a social security charge of 2,700 euros per year for this privilege. I haven’t received a bill but now live in dread of it!

My work is part time and my average declaration has been 500 euros per quarter because I also do private lessons under CESU. I have completed a BAFA to become an animatrice in the hope this might open opportunities to do workshops with children. So the intention was to build up a reasonable business, in which case the conjoint collaborateur might have made sense. I understand I need to earn about 10,000 euros a year to contribute towards the pension scheme.

In the meantime, my husband is now in the process of setting up his own business in France as an electrician auto-entrepreneur. He should be eligible for ACCRE given he has been with the pole emploi for more than 6 months. I will be doing the administration for the business, which means that particularly in the early stages my own business will just tick along at the current level. I am not looking to expand until everything is settled. What would you advise I do about the conjoint collaborateur in both cases?
