The Secretary shall notify in writing the person described in section 6321 of the filing of a notice of lien under section 6323. given in person; left at the dwelling or usual place of business of such person; or sent by certified or registered mail to such person’s last known address, the amount of unpaid tax; the right of the person to request a hearing during the 30-day period beginning on the day after the 5-day period described in paragraph (2); the administrative appeals available to the taxpayer with respect to such lien and the procedures relating to such appeals; the provisions of this title and procedures relating to the release of liens on property; and the provisions of section 7345 relating to the certification of seriously delinquent tax debts and the denial, revocation, or limitation of passports of individuals with such debts pursuant to section 32101 of the FAST Act. If the person requests a hearing in writing under subsection (a)(3)(B) and states the grounds for the requested hearing, such hearing shall be held by the Internal Revenue Service Independent Office of Appeals. A person shall be entitled to only one hearing under this section with respect to the taxable period to which the unpaid tax specified in subsection (a)(3)(A) relates.

A taxpayer may waive the requirement of this paragraph. To the extent practicable, a hearing under this section shall be held in conjunction with a hearing under section 6330. For purposes of this section, subsections (c), (d) (other than paragraph (3)(B) thereof), (e), and (g) of section 6330 shall apply.
