I agree with Shri Kasturi Sethi Ji!
I wish to add the followings:
Query talks about ITC reversal u/r 44 (6). While Rule 44 indeed have the heading 'Manner of reversal of credit under special circumstances', subject sub-rule 6 reads as under:
"The amount of input tax credit for the purposes of sub-section (6) of section 18 relating to capital goods shall be determined in the same manner as specified in clause (b) of sub-rule (1) and the amount shall be determined separately for input tax credit of 3[central tax, State tax, Union territory tax and integrated tax]:
Provided that where the amount so determined is more than the tax determined on the transaction value of the capital goods, the amount determined shall form part of the output tax liability and the same shall be furnished in FORM GSTR-1."
Rule 2 (82) of the CGST Rules, 2017 reads as under:
"“output tax” in relation to a taxable person, means the tax chargeable under this Act on taxable supply of goods or services or both made by him or by his agent but excludes tax payable by him on reverse charge basis"
Reading Section 18 (6) (as reproduced in earlier post) with the Rule 44 (6) along-with proviso thereunder, I am of the view that amount payable is NOT 'Reversal of any ITC' but tax-liability against supply of capital goods.
This is so because heading of any section / rule - which is contrary to what is stated in underlying section / rule - does not come into picture for interpretation of section / rule when subject provisions under such headings are unambiguous & clear in nature.
In other words, due to wordings used in Section 18 (6) read with Rule 44 (6), amount calculated u/r 44 (6) is NOT 'Amount of ITC to be reversed' against the subject transaction under discussion here but same is 'Tax payable' against outward supply of capital goods.
Consequently, you need not show this amount as 'ITC reversed' while filing GSTR-3B but same should be shown as tax charged & paid while raising tax-invoice as outward supply' and reporting it in Form GSTR-1.
HOW THIS MATTERS:
All this also means that buyer will also be eligible to avail ITC against taxes so charged by you and thereby, there will not be any loss to the person selling such goods.
All above are strictly personal views of mine and the same should not be construed as professional advice / suggestion.
