It is mandatory for a company director to submit a tax return with HMRC if a return has been issued. But what about if a Self-Assessment tax return has not been issued to a director he does not have a tax liability?

As per the above HMRC guidance, you must complete a tax return if you are a company director (unless you are a director of a non-profit organization, for example a charity, and don’t receive any payments or benefits).

There is no requirement under TMA 1970 s7 for a director to register for self-assessment if there is no further tax liability for the year.

Therefore, if a director of the company has no further tax liability for a tax year AND no self-assessment tax return has been issued by HMRC, then there is no requirement for the director to file a tax return for the year in question.
