(b) LiabilityAny 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.
(c) Period of limitationsThe period of limitations for assessment of any such liability of a transferee or a fiduciary shall be as follows:(1) Initial transfereeIn 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; (2) Transferee of transfereeIn the case of the liability of a transferee of a transferee, within 1 year after the expiration of the period of limitation for assessment against the preceding transferee, but not more than 3 years after the expiration of the period of limitation for assessment against the initial transferor; except that if, before the expiration of the period of limitation for the assessment of the liability of the transferee, a court proceeding for the collection of the tax or liability in respect thereof has been begun against the initial transferor or the last preceding transferee, respectively, then the period of limitation for assessment of the liability of the transferee shall expire 1 year after the return of execution in the court proceeding. (3) FiduciaryIn the case of the liability of a fiduciary, not later than 1 year after the liability arises or not later than the expiration of the period for collection of the tax in respect of which such liability arises, whichever is the later.

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).
