If the Director of Finance 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 will be immediately due and payable. Unless the taxpayer against whom a jeopardy assessment is made petitions for reassessment, within twenty (20) days after service of notice of jeopardy assessment, such assessment becomes final. Such petition for reassessment must be accompanied by such securities as the Director of Finance deems necessary. (Ord. 1-7-03.)
