GST Council in its 50th meeting had recommended that ISD (Input Service Distributor) procedure as laid down in Section 20 of the CGST Act, 2017 may be made mandatory prospectively for distribution of ITC in respect of input services procured by Head Office (HO) from a third party but attributable to both HO and Branch Office (BO) or exclusively to one or more BOs. The Council has now recommended amendments in Section 2(61) and section 20 of CGST Act, 2017 as well amendment in rule 39 of CGST Rules, 2017 in respect of the same.
