The liability of a fiduciary under section 3713(b) of title 31, United States Code, in respect of the payment of any tax described in subparagraph (A) from the estate of the taxpayer, the decedent, or the donor, as the case may be.
The liability, at law or in equity of a transferee of property of any person liable in respect of any tax imposed by this title (other than a tax imposed by subtitle A or B), but only if such liability arises on the liquidation of a partnership or corporation, or on a reorganization within the meaning of section 368(a).
Any liability referred to in subsection (a) may be either as to the amount of tax shown on a return or as to any deficiency or underpayment of any tax.
In the case of the liability of an initial transferee, within 1 year after the expiration of the period of limitation for assessment against the transferor;
If before the expiration of the time prescribed in subsection (c) for the assessment of the liability, the Secretary and the transferee or fiduciary have both consented in writing to its assessment after such time, the liability may be assessed at any time prior to the expiration of the period agreed upon. The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of the period previously agreed upon. For the purpose of determining the period of limitation on credit or refund to the transferee or fiduciary of overpayments of tax made by such transferee or fiduciary or overpayments of tax made by the transferor of which the transferee or fiduciary is legally entitled to credit or refund, such agreement and any extension thereof shall be deemed an agreement and extension thereof referred to in section 6511(c).
If the agreement is executed after the expiration of the period of limitation for assessment against the taxpayer with reference to whom the liability of such transferee or fiduciary arises, then in applying the limitations under section 6511(c) on the amount of the credit or refund, the periods specified in section 6511(b)(2) shall be increased by the period from the date of such expiration to the date of the agreement.
For purposes of this section, if any person is deceased, or is a corporation which has terminated its existence, the period of limitation for assessment against such person shall be the period that would be in effect had death or termination of existence not occurred.
The running of the period of limitations upon the assessment of the liability of a transferee or fiduciary shall, after the mailing to the transferee or fiduciary of the notice provided for in section 6212 (relating to income, estate, and gift taxes), be suspended for the period during which the Secretary is prohibited from making the assessment in respect of the liability of the transferee or fiduciary (and in any event, if a proceeding in respect of the liability is placed on the docket of the Tax Court, until the decision of the Tax Court becomes final), and for 60 days thereafter.
In the absence of notice to the Secretary under section 6903 of the existence of a fiduciary relationship, any notice of liability enforceable under this section required to be mailed to such person, shall, if mailed to the person subject to the liability at his last known address, be sufficient for purposes of this title, even if such person is deceased, or is under a legal disability, or, in the case of a corporation, has terminated its existence.
As used in this section, the term “transferee” includes donee, heir, legatee, devisee, and distributee, and with respect to estate taxes, also includes any person who, under section 6324(a)(2), is personally liable for any part of such tax.
