How to i transfer the preparation of VAT returns from us the accountant to the client.

Hi paulbryan Thanks for reaching out to us here on the Community. You'd have to remove the client from your ASA, the client would then be able to connect MTD, they would have to be at least a company admin user to be able to connect MTD. We've included an article that you could forward to your client that references how to connect MTD: https://intuit.me/4cU1jc4
