Assessment

The amount of tax due from a person liable to pay tax under this Act, shall be assessed separately for such period as may be prescribed. If the assessing authority is satisfied that the return furnished by a person liable to pay tax is correct and complete, he shall assess the amount of tax due from the person on the basis of such return. If the assessing authority is of the opinion that the return furnished by a person liable to pay tax is not correct and complete, he shall serve on such person, in the prescribed manner a notice requiring him, to attend on a date and at a place specified therein, and produce or cause to be produced, all evidence on which the said person relies in support of his return or to produce such evidence as specified in the notice and on the date specified in the notice, and as soon as may be, thereafter, the assessing authority shall after considering all the evidence which may be produced, assess the amount of tax due from the person. If a person fails to comply with the requirements of any notice issued under sub­section (3), the assessing authority shall determine the purchase value of the motor vehicle under the proviso to clause (n) of Section 2 to the best of his judgment and assess the amount of tax due from him and may direct the importer to pay in addition to the tax so assessed penalty as specified in sub-section (1) of Section 18. No order of assessment under sub-section (3) or sub-section (4) or any period shall be made after the expiry of three years from the last date prescribed for filing of returns for that period. If, for any reason such order is not made within the period aforesaid, then the return so filed shall be deemed to have been accepted as correct and complete for assessing the tax due from such person.
