(a) General rule. — For the privilege of doing business in this state or deriving rents or royalties from real or tangible personal property located in this state, including, but not limited to, natural resources in place and standing timber, a partnership, S corporation, estate or trust, which is treated as a pass-through entity for federal income tax purposes and which has taxable income for the taxable year derived from or connected with West Virginia sources any portion of which is allocable to a nonresident partner, nonresident shareholder, or nonresident beneficiary, as the case may be, shall pay a withholding tax under this section, except as provided in subsections (c) and (k) of this section.

(b) Amount of withholding tax. —

(1) In general. — The amount of withholding tax payable by any partnership, S corporation, estate or trust, under subsection (a) of this section, shall be equal to four percent of the effectively connected taxable income of the partnership, S corporation, estate or trust, as the case may be, which may lawfully be taxed by this state and which is allocable to a nonresident partner, nonresident shareholder, or nonresident beneficiary of a trust or estate: Provided, That for taxable years commencing on or after January 1, 2008, the amount of withholding tax payable by any partnership, S corporation, estate or trust, under subsection (a) of this section, shall be equal to six and one-half percent of the effectively connected taxable income of the partnership, S corporation, estate or trust, as the case may be, which may lawfully be taxed by this state and which is allocable to a nonresident partner, nonresident shareholder, or nonresident beneficiary of a trust or estate.

(2) Credits against tax. — When determining the amount of withholding tax due under this section, the pass-through entity may apply any tax credits allowable under this chapter to the pass-through entity which pass through to the nonresident distributees: Provided, That in no event may the application of any credit or credits reduce the tax liability of the distributee under this article to less than zero.

(c) When withholding is not required. — Withholding may not be required:

(1) On distribution to a person, other than a corporation, who is exempt from the tax imposed by this article. For purposes of this subdivision, a person is exempt from the tax imposed by this article only if such person is, by reason of that person"s purpose or activities, exempt from paying federal income taxes on such person"s West Virginia source income. The pass-through entity may rely on the written statement of the person claiming to be exempt from the tax imposed by this article provided the pass-through entity discloses the name and federal taxpayer identification number for all such persons in its return for the taxable year filed under this article or §11-24-1 et seq. of this code; or

(2) On distributions to a corporation which is exempt from the tax imposed by §11-24-1 et seq. of this code. For purposes of this subdivision, a corporation is exempt from the tax imposed by §11-24-1 et seq. of this code only if the corporation, by reason of its purpose or activities is exempt from paying federal income taxes on the corporation"s West Virginia source income. The pass-through entity may rely on the written statement of the person claiming to be exempt from the tax imposed by §11-24-1 et seq. of this code provided the pass-through entity discloses the name and federal taxpayer identification number for all such corporations in its return for the taxable year filed under this article or §11-24-1 et seq. of this code; or

(3) On distributions when compliance will cause undue hardship on the pass-through entity: Provided, That no pass-through entity shall be exempt under this subdivision from complying with the withholding requirements of this section unless the Tax Commissioner, in his or her discretion, approves in writing the pass-through entity"s written petition for exemption from the withholding requirements of this section based on undue hardship. The Tax Commissioner may prescribe the form and contents of such a petition and specify standards for when a pass-through entity will not be required to comply with the withholding requirements of this section due to undue hardship. Such standards shall take into account (among other relevant factors) the ability of a pass-through entity to comply at reasonable cost with the withholding requirements of this section and the cost to this state of collecting the tax directly from a nonresident distributee who does not voluntarily file a return and pay the amount of tax due under this article with respect to such distributions; or

(4) On distributions by nonpartnership ventures. An unincorporated organization that has elected, under Section 761 of the Internal Revenue Code, to not be treated as a partnership for federal income tax is not treated as a partnership under this article and is not required to withhold under this section. However, such unincorporated organizations shall make and file with the Tax Commissioner a true and accurate return of information under §11-21-58(c) of this code, under such rules and in such form and manner as the Tax Commissioner may prescribe, setting forth: (A) The amount of fixed or determinable gains, profits, and income; and (B) the name, address and taxpayer identification number of persons receiving fixed or determinable gains, profits or income from the nonpartnership venture.

This information shall be provided in an electronic format approved by the Tax Commissioner.

(d) Payment of withheld tax. —

(B) Partnerships, estates, and trusts. — The 15th day of the fourth month following the close of the taxable year of the partnership, estate or trust, with the annual return of the partnership, estate or trust due under this article, unless paragraph (C) of this subdivision applies: Provided, That for tax years beginning after December 31, 2015, partnerships shall pay the amount required to be withheld to the Tax Commissioner, along with the annual return of the partnership due under this article, on the 15th day of the third month following the close of the taxable year of the partnership, unless paragraph (C) of this subdivision applies.

(2) Special rules. —

(A) Where there is extension of time to file return. — An extension of time for filing the returns referenced in subdivision (1) of this subsection does not extend the time for paying the amount of withholding tax due under this section. In this situation, the pass-through entity shall pay, by the date specified in subdivision (1) of this subsection, at least 90 percent of the withholding tax due for the taxable year, or 100 percent of the tax paid under this section for the prior taxable year, if such taxable year was a taxable year of 12 months and tax was paid under this section for that taxable year. The remaining portion of the tax due under this section, if any, shall be paid at the time the pass-through entity files the return specified in subdivision (1) of this subsection. If the balance due is paid by the last day of the extension period for filing the return and the amount of tax due with such return is 10 percent or less of the tax due under this section for the taxable year, no additions to tax may be imposed under §11-10-1 et seq. of this code with respect to balance so remitted. If the amount of withholding tax due under this section for the taxable year is less than the estimated withholding taxes paid for the taxable year by the pass-through entity, the excess shall be refunded to the pass-through entity or, at its election, established as a credit against withholding tax due under this section for the then current taxable year.

(B) Deposit in trust for Tax Commissioner. — The Tax Commissioner may, if the commissioner believes such action is necessary for the protection of trust fund moneys due this state, require any pass-through entity to pay over to the Tax Commissioner the tax deducted and withheld under this section, at any earlier time or times.

(1) Allowance of credit. — Each nonresident partner, nonresident shareholder, or nonresident beneficiary shall be allowed a credit for such partner"s or shareholder"s or beneficiary"s share of the tax withheld by the partnership, S corporation, estate or trust under this section: Provided, That when the distribution is to a corporation taxable under §11-24-1 et seq. of this code, the credit allowed by this section shall be applied against the distributee corporation"s liability for tax under §11-24-1 et seq. of this code.

(2) Credit treated as distributed to partner, shareholder, or beneficiary. — Except as provided in rules, a nonresident partner"s share, a nonresident shareholder"s share, or a nonresident beneficiary"s share of any withholding tax paid by the partnership, S corporation, estate or trust under this section shall be treated as distributed to the partner by the partnership, or to the shareholder by the S corporation, or to the beneficiary by the estate or trust on the earlier of:

(A) The day on which the tax was paid to the Tax Commissioner by the partnership, S corporation, estate, or trust; or

(2) A copy of the information statements required by this subsection shall be filed with the West Virginia return filed under this article (or §11-24-1 et seq. of this code for S corporations) by the pass-through entity for its taxable year to which the distribution relates. This information statement shall be furnished to each nonresident distributee on or before the due date of the pass-through entity"s return under this article or §11-24-1 et seq. of this code for the taxable year, including extensions of time for filing such return, or such later date as may be allowed by the Tax Commissioner.

(i) Liability for withheld tax. — Every person required to deduct and withhold tax under this section is hereby made liable for the payment of the tax due under this section for taxable years (of such persons) beginning after December 31, 1991, except as otherwise provided in this section. The amount of tax required to be withheld and paid over to the Tax Commissioner shall be considered the tax of the partnership, estate, or trust, as the case may be, for purposes of §11-9-1 et seq. and §11-10-1 et seq. of this code. Any amount of tax withheld under this section shall be held in trust for the Tax Commissioner. No partner, S corporation shareholder, or beneficiary of a trust or estate, may have a right of action against the partnership, S corporation, estate, or trust, in respect to any moneys withheld from the person"s distributive share and paid over to the Tax Commissioner in compliance with or in intended compliance with this section.

(j) Failure to withhold. — If any partnership, S corporation, estate or trust fails to deduct and withhold tax as required by this section and thereafter the tax against which the tax may be credited is paid, the tax so required to be deducted and withheld under this section may not be collected from the partnership, S corporation, estate, or trust, as the case may be, but the partnership, S corporation, estate, or trust may not be relieved from liability for any penalties or interest on additions to tax otherwise applicable in respect of the failure to withhold.
