Input tax credit requires electronic declaration, professional certification when large, and phased capital goods adjustment.

Input tax credit for inputs in stock, inputs contained in semi-finished or finished goods held in stock, and for capital goods is subject to an electronic declaration in FORM GST ITC-01 within the prescribed time specifying details as on the relevant cut-off date; certification by a practicing chartered or cost accountant is required if the aggregate claim exceeds the prescribed threshold; capital goods credit is adjusted by a fixed quarterly reduction from the invoice or receipt date; and claimed credit must be verified against corresponding supplier filings on the common portal.
