Enacted Missouri legislation provides that, for cash transactions only, a vendor may round the total amount of sale due on a transaction to the nearest five cents. Totals ending in $0.01, $0.02, $0.06, or $0.07 may be rounded down to the nearest amount divisible by $0.05. Totals ending in $0.03, $0.04, $0.08, or $0.09 may be rounded up to the nearest amount divisible by $0.05.
Rounding must be applied only to the final total of the transaction after all items, discounts, and taxes have been calculated. This rounding does not apply to transactions paid by credit, debit, or other noncash methods. The applicable amount of tax due in accordance with the tax brackets must be remitted to the Department of Revenue regardless of the method of payment from the taxpayer’s customer.
In addition, a vendor will not be in violation of any requirements, laws, regulations, or standards of a state or political subdivision in Missouri based on actions taken in good faith and in compliance with the provisions of this legislation.
