K-1 INFORMATION

A Schedule K-1 is the required form for reporting a partner's share of the partnership tax items. If you owned common units at any time during the tax year, you will receive a Schedule K-1. If you believe you received a Schedule K-1 in error, please contact our Tax Package Support Center at 1-800-371-2188. K-1 Tax Reporting Website. RETURN OF CAPITAL FAQ Assume ONEOK communicates that 25% of the payment should be treated as a return of capital and that 75% should be treated as a taxable dividend. Therefore, for U.S. income tax reporting, the shareholder should treat $0.20 of the $0.80 payment, or 25%, as a return of capital and $0.60 of the $0.80 payment, or 75%, as a taxable dividend.
