“(A) shall apply only to the extent that such credit or refund relates to an underlying tax liability properly disputed at the hearing requested under this section, and

“(B) shall not result in a suspension of the running of such period of limitations after any date on which a lapse of a deadline, a court filing, or a court order establishes that the taxpayer has forfeited or otherwise lost the right to pursue such dispute.”.

(c) Cross reference.—Section 6511(i) of such Code is amended by adding at the end the following new paragraph:

“(8) For limitations in case of collection action proceedings, see section 6330(e).”.

(a) In general.—Section 6402 of the Internal Revenue Code of 1986 is amended by adding at the end the following new subsection:

“(o) Prohibition on crediting of overpayments against disputed tax liability during collection action proceedings.—If a hearing is properly requested under section 6320(a)(3)(B) or 6330(a)(3)(B), and an underlying tax liability referred to in section 6330(c)(2)(B) is properly disputed at such hearing, such tax liability shall not, except with the consent of the taxpayer, be taken into account under subsection (a) for the period during which the period of limitations for filing a claim for credit or refund relating to such tax liability is suspended by reason of section 6330(e).”.

(b) Clarification of application of certain levy hearing rules to lien hearings.—Section 6330(c)(2)(A) of such Code is amended by striking “unpaid tax or the proposed levy” and inserting “unpaid tax, collection action, or proposed collection action”.
