§ 7485.
(a)
Upon notice of appeal
Notwithstanding any provision of law imposing restrictions on the assessment and collection of deficiencies, the review under section 7483 shall not operate as a stay of assessment or collection of any portion of the amount of the deficiency determined by the Tax Court unless a notice of appeal in respect of such portion is duly filed by the taxpayer, and then only if the taxpayer—
(1)
on or before the time his notice of appeal is filed has filed with the Tax Court a bond in a sum fixed by the Tax Court not exceeding double the amount of the portion of the deficiency in respect of which the notice of appeal is filed, and with surety approved by the Tax Court, conditioned upon the payment of the deficiency as finally determined, together with any interest, additional amounts, or additions to the tax provided for by law, or
(2)
has filed a jeopardy bond under the income or estate tax laws.
If as a result of a waiver of the restrictions on the assessment and collection of a deficiency any part of the amount determined by the Tax Court is paid after the filing of the appeal bond, such bond shall, at the request of the taxpayer, be proportionately reduced.
