Some States including California charge a Can or Bottle tax on Drinks known as California Redemption Value or CRV tax. Our vendors charge us these CRV taxes. These taxes are not based on percentages, but a defined amount I.E. for 12 oz soda cans it’s $0.05. I think a feature allowing to add non-percentage taxes in the tax scheme an idea place for these. both On-Premise and Cloud versions.
