How can tax paid be recouped and adjusted in case of return of goods attracting reverse charge?

There is no provision in section 34 of the CGST Act or Rule 52 of the CGST
Rules, 2017 regarding reversal of tax paid. Equity demands that relief be allowed to the recipient who has paid the tax so that the recipient may apply for refund under section 54 of the CGST Act and not issue credit note or revised invoice for which there is no provision. This relief to claim refund will be subject to credit not being availed by the recipient on the tax so paid.

Is reverse charge applicable on awarding contract or issuing Purchase Order (PO)?

Reverse charge is applicable only when there is a supply. Supply ‘agreed to be made’ is regarded as a supply only in case of supply under section 7(1)(a) and 7(1)(c). Even though actual supply is yet to take place, in the case of supplies covered by these two provisions, tax would be payable on award of contract or issue of PO because this itself amounts to supply. However, Table 4 of GSTR-2 requires reference to be made to invoice in respect of supplies liable to reverse charge but Rule 52 does not provide for issuance of invoice earlier than the time of payment. As such the absence of machinery provisions to pay tax at the time of contract / PO, it appears that the liability fails.

Does tax liability u/s 9(5) come within reverse charge?

No, definition of reverse charge given in section 2(98) refers only to section 9(3) and section 9(4). Tax payment by e commerce operator in case of specified services under section 9(5) would not be a case of reverse charge but a new specie because the e commerce operator facilitates the supply through the digital network and collects payment from recipient and passes it on to supplier.

If all the Supplies of a person are under Reverse charge mechanism, can such person not register under the Act although the aggregate turnover is exceeding the prescribed limit

It is not necessary for the supplier to take registration since the Notification No. 05/2017- Central Tax dated June 19, 2017, provides for the same. For Example: – In case of an independent director providing services, and his only income is from independent directorship (or such other services covered under RCM) to the company, in this case the director won’t be required to take registration.
