The CIS rules may seem fairly simple, until one of your suppliers says that he is outside them and expects to be paid gross. Is he in fact? Borderline cases like that are never easy, and sometimes seem to lack logic (for example, carpet fitting is outside the Scheme, but fitting any other kind of flooring will frequently be in). If you are caught not having operated the Scheme when you should have done, you really are in the hands of the Revenue and your suppliers in mitigating your liabilities.
David Kirk & Co. Ltd. can help you navigate your way through all this. We can also assist clients in making sure that they do not lose their gross payment status, or in getting it back again if they do.
