If someone is self employed, and decides to become a director instead, do they need to deregister as self employed with HMRC, or is this an automatic thing when they submit the tax return?
eg. Someone decides on 31/10/18 they are no longer self employed, but then sets up a Ltd company with start date of 01/11/18, should they have something available to them now from HMRC, 25/03/19, that proves the self employment has ended?
