The New York Supplemental Commodity Statement (Forms CBD, CATV) is a form required by the New York State Department of Taxation and Finance to be completed by a taxpayer who owns commodities, such as stocks, bonds, or other investments, in order to claim a deduction from their taxable income. The form must be completed by the taxpayer and submitted to the Department of Taxation and Finance. The two forms used are the CBD and CATV forms.

This form is used to report the sale of commodities such as stocks, bonds, or other investments. The CATV form (CADV-1) is used to report the purchase, receipt, or acquisition of commodities that are held in a customer's account at a broker or dealer registered with the New York State Department of Taxation and Finance. This form is used to report the purchase of commodities such as stocks, bonds, or other investments.
