2 Where a company has delivered a self-assessment for any accounting period of the company, the Service may —

b refuse to accept the self-assessment and proceed as provided in subsection (3) upon any failure as mentioned and the like consequences shall ensue.

3 Where, for any accounting period, a company files a self-assessment which was rejected by the Service or has failed to file self-assessment as provided in section 277 of this Act within the time limited by that section or has failed to comply with any notice given to it under section 278 or 279 of this Act within the time specified in such notice or within any extended time provided in section 281 of this Act, and the Service is of the opinion that the company is liable to pay hydrocarbon tax, the Service may estimate the amount of the tax to be paid by the company for that accounting period and make an assessment accordingly, provided that —
