Job work goods reporting: mandatory submission of GST ITC form to record inputs and capital goods movements. Form GST ITC-04 requires taxpayers to report inputs and capital goods sent to job workers and their return or onward supply. The form captures GSTIN and identity details, itemised particulars of goods sent (including challan, description, quantity, taxable value and tax components), and segregates receipts into three tables for goods returned to the same job worker, goods received from a different job worker, and goods supplied from the job worker's premises. It mandates cross-referencing original challans, reporting losses and wastes, specifies mandatory/optional columns, and culminates in a verification declaration by an authorised signatory.
