If the Mayor believes that the collection of any tax which he is required to administer will be jeopardized by delay, he shall thereupon make an assessment of the tax, noting that fact upon the assessment. The amount assessed shall be immediately due and payable. Unless the taxpayer against whom a jeopardy assessment is made petitions for reassessment within twenty days after service of notice of the jeopardy assessment, such assessment becomes final.
A petition for reassessment by a person against whom a jeopardy assessment has been made must be accompanied by such security as the Mayor may deem necessary to insure compliance with this article.
(1977 Code 5-415.)
