2.7 Failure to register.—Under section 13(5) of the Act, if a person required to register fails to register, the Comptroller may register the person and specify the effective date of the registration. For example, assume that a person fails to register, but was required to do so because taxable supplies exceeded the threshold on 31 December, 2012. If the Comptroller discovers on 15 July, 2013 that the person was required to register as of 31 December, 2012, the Comptroller may register the person, effective 1 January, 2013.
