57-39.4-25. (324) Rounding 1. After December 31, 2005, each member state shall adopt a rounding algorithm that meets the following criteria: a. Tax computation must be carried to the third decimal place; and b. The tax must be rounded to a whole cent using a method that rounds up to the next cent whenever the third decimal place is greater than four. 2. Each state shall allow sellers to elect to compute the tax due on a transaction on an item or an invoice basis and shall allow the rounding rule to be applied to the aggregated state and local taxes. No member state shall require a seller to collect tax based on a bracket system.
