The short answer, explained
You can ask to record an HMRC meeting, and many advisers do. HMRC does not have to agree, but its own guidance treats recording as acceptable when both parties know in advance.
Refusing to record does not mean you have no protection. You can take your own notes, bring an adviser, and ask HMRC for a written summary once the meeting ends.
For most directors, the practical answer is to raise it early with the caseworker rather than assume either a right or a ban.
