Sales Tax: Rounded Then Totaled or Totaled Then Rounded?
Taxes should not be calculated at the item level. Taxes should be aggregated by tax group at the summary level. The right way everywhere is LINE ITEMS SUMMARY PS:If you'd charge at the item level, it would be too easy to circumvent the law by splitting your items or services into 900 items at $0.01 (Which once rounded would mean no tax). This could happen in the banking or plastic pellets industry.
