In any case in which the Commissioner of Revenue Services may grant an extension of the time for filing of any return related to any state tax and in which a taxpayer is unable, by reason of illness, absence or other good cause, to sign a request for an extension, any person standing in close personal or business relationship to the taxpayer may sign the request on his behalf and shall be considered as a duly authorized agent for this purpose, provided the request sets forth the reasons for a signature other than the taxpayer's and the relationship existing between the taxpayer and the signer.
