21. Dear Sirs,
One of the conditions of Section 16 (2) is filing of return under Section 39 i.e. GSTR-3B. The does not prohibit belated filing of GSTR-3B albeit with late fee and interest. Thus, if a tax payer, for some genuine reason, say due to financial crisis, is unable to pay the tax liability in cash and therefore, cannot file his GSTR-3B returns for whole of the financial year and files the same only after the cut-off date specified under Section 16 (4), he should be allowed to avail ITC for all the relevant months from April to March while filing the returns since it is only when he files GSTR-3B reeturns, he becomes entitled to the ITC. The law does not permit to file the return unless the entire tax liability in the return is paid. Thus, even if the tax payer wishes to avail the ITC, he is prevented from doing so. Since Section 16 (2) starts with non-obstante clause, it will have an overriding effect on Section 16 (4). In my humble opinion, Section 16 (4) is applicable only in situations where the tax payer has not availed ITC in spite of having filed GSTR-3B return. In that case, he is allowed, as per Section 16 (4), to defer availment till the specified cut off date. In short, provisions of Section 16 (4) are for deferment of availing of ITC after filing of the returns.
Kindly provide views on the above.
