ITC on invoive

If your Input Tax Credit (ITC) has been disallowed because your invoice lacked the necessary details as per GST regulations, you should request your supplier to issue a corrected invoice that complies with GST rules. Once you receive the proper invoice, you can then claim your ITC. The proviso to Rule 36 of the GST rules outlines the mandatory fields required for a tax invoice to claim ITC, but allows for credit even if some details are missing, provided key information like tax charged, goods/services description, total value, supplier/recipient GSTIN, and place of supply are present.
