Why is Florida rounding strangely?


Florida calculations with AvaTax are not working as expected. It is off by a penny or so. It appears to be due to rounding errors.

  • Rounding in Florida must be done in a very specific way. Using a calculator and rounding as you normally would is not how the Florida Department of Revenue says tax must be calculated.
    • You can see more information about this under the How Tax is Calculated section on this page.
    • Also, this link shows the tax brackets that must be used when tax is calculated.
  • As a result, it is expected that you may not see different results with Document or Line Level Rounding set in your company settings for transactions within the state of Florida
