MS Code § 27-8-19 (2020)
2020 Mississippi Code|Title 27 - Taxation and Finance|Chapter 8 - Mississippi S Corporation Income Tax Act|§ 27-8-19. Filing of corporate income tax return; when required; information required; composite returns; agreement or payment as to nonresident shareholders

  An S corporation which engages in activities in this state that would subject a C corporation to the requirement to file a return under Section 27-7-37 shall file with the State Tax Commission an annual return, in the form prescribed by the commission, on or before the due date prescribed for the filing of C corporation returns under Section 27-7-41. The return shall set forth the name, address and social security or federal identification number of each shareholder; the income attributable to the state and income not attributable to the state with respect to each shareholder as determined under this chapter; and such other information as the commission may prescribe by regulation. The S corporation shall furnish, on or before the day on which such return is filed, to each person who was a shareholder during the year a copy of such information shown on the return as the commission may prescribe by regulation. The S corporation also shall maintain the accumulated adjustments account described in Section 27-8-17(3)(b).   The State Tax Commission shall permit S corporations to file composite returns and to make composite payments of tax on behalf of some or all of its nonresident shareholders. The commission may permit composite returns and payments to be made on behalf of resident shareholders.   With respect to each of its nonresident shareholders and for each taxable period, an S corporation shall (a) timely file with the commission an agreement as provided in subsection (4) of this section or (b) make a payment to this state as provided in subsection (5) of this section. An S corporation that timely files an agreement as provided in subsection (4) of this section with respect to a nonresident shareholder for a taxable period shall be considered to have timely filed such an agreement for each subsequent taxable period. An S corporation that does not timely file such an agreement for a taxable period shall not be precluded from timely filing such an agreement for subsequent taxable periods.   The agreement referred to in subsection (3)(a) of this section is an agreement of a nonresident shareholder of the S corporation:   To file a return and to make timely payment of all taxes imposed on the shareholder by this state with respect to the income of the S corporation; and   To be subject to personal jurisdiction in this state for purposes of the collection of income taxes, together with related interest and penalties, imposed on the shareholder by this state with respect to the income of the S corporation.  The agreement will be considered to be timely filed for a taxable period and for all subsequent taxable periods if it is filed at or before the time the annual return for such taxable period is required to be filed.   In the event the S corporation fails to obtain an agreement of a nonresident shareholder as provided in subsection (3)(a) of this section or in the event a nonresident shareholder of an S corporation fails to file a return and to make timely payments of all taxes imposed on the shareholder by this state as provided in subsection (4)(a) of this section, the S corporation shall make a payment to the state as provided in subsection (5) of this section.      The payment referred to in subsection (3)(b) and (4) of this section shall be in an amount equal to the highest marginal tax rate in effect under Section 27-7-5 multiplied by the shareholder's pro rata share of the income attributable to the state reflected on the corporation's return for the taxable period. An S corporation shall be entitled to recover a payment made pursuant to the preceding sentence from the shareholder on whose behalf the payment was made. Any such payment for a taxable period must be made at or before the time the annual return for such taxable period is required to be filed.   Any amount paid by the corporation to this state under subsection (2) or (5) of this section shall be considered to be a payment by the shareholder on account of the income tax imposed on the shareholder for the taxable period under Section 27-7-5.
