Dear Querist,
Apex court's observation that 'interest is compensatory in nature' in case of Pratibha Processors - 1996 (10) TMI 88 - SUPREME COURT must be understood in the context of factual aspects & dispute which was present in that case. Furthermore, Para 14 needs to be read carefully before taking a line from the judgement and same reads as follows:
"14.In the above backdrop, let us consider the scope and content of Section 61(2) of the Act as it existed at the relevant time. Section 61(1) prescribes the period during which the goods imported may remain in the warehouse. The normal period in different cases are provided therein. Extension of time in special cases is also provided. If the goods imported remain in warehouse beyond the period provided or extended under Section 61(1), the consequences are specified in Section 61(2) of the Act. As per the provisions of the Act duty is payable (only) when the goods are cleared. If the goods are not cleared within the time granted under Section 61(1) of the Act, and the goods are cleared later, the payment of duty exigible on the goods gets automatically delayed. It is to meet the said contingency. Section 61(2) provides that if the goods warehoused are cleared beyond the time specified or granted under Section 61(1) of the Act, interest not exceeding 18% per annum shall be payable on the amount of duty on the warehoused goods. It is implicit from the language of Section 61(2) of the Act that the interest shall be payable on the amount of duty "payable or due" on the warehoused goods for the period from the expiry of period specified or granted till the date of clearance of the goods from the warehouse. In this case, on the date of clearance of the goods, no duty is payable. The goods are not exigible to duty at that time. Calculation of interest is always on the principal amount. The "interest" payable under Section 61(1)(2) of the Act is a mere "accessory" of the principal and if the principal is not recoverable/payable, so is the interest on it. This is a basic principle based on common sense and also flowing from the language of Section 61(1)(2) of the Act. The principal amount herein is the amount of duty payable on clearance of goods. When such principal amount is nil because of the exemption, a fortiori, interest payable is also nil. In other words, we are clear in our mind that the interest is necessarily linked to the duty payable. The interest provided under Section 61(2) has no independent or separate existence. When the goods are wholly exempted from the payment of duty on removal from the warehouse, one cannot be saddled with the liability to pay interest on a non-existing duty. Payment of interest under Section 61(2) is solely dependent upon the exigibility or factual liability to pay the principal amount, that is, the duty on the warehoused goods at the time of delivery. At that time, the principal amount (duty) is not payable due to exemption. So, there is no occasion or basis to levy any interest, either. We hold accordingly."
In above case, there was no duty payable and hence, no interest was payable as per Apex Court. So, taking a line from such judgement that 'interest is compensatory in nature' will not help your case because in your case, tax is indeed payable and same is paid after due date.
STILL, Govt. had made retrospective amendment u/s 50 where following proviso was added under sub-section (1):
".....
Provided that the interest on tax payable in respect of supplies made during a tax period and declared in the return for the said period furnished after the due date in accordance with the provisions of section 39, except where such return is furnished after commencement of any proceedings under section 73 or section 74 in respect of the said period, shall be payable on that portion of the tax which is paid by debiting the electronic cash ledger"
Thus, no interest is still payable for delayed payment of tax by debiting the electronic credit ledger ledger (except where such return is furnished after commencement of any proceedings under section 73 or section 74 in respect of the said period).
In conclusion, the case of Pratibha Processors - 1996 (10) TMI 88 - SUPREME COURTdoes not help tax-payer to avoid interest-liability if there is indeed delayed payment of taxes (i.e. payment of taxes after due date).
P.S. Not having an option to file a return without payment of full taxes, as self-assessed in that return, is altogether different issue / ground to argue against non-levy of interest.
These are ex facie views of mine and the same should not be construed as professional advice / suggestion.
