ALERT: Changes to tax calculation in New Mexico and Florida

New Mexico

In accordance with House Bill 6 passed by the New Mexico state legislature, and signed by Governor Grisham on April 4, 2019, Avalara has conducted a statewide update to associate the local compensating tax at a rate equal to the combined municipal and county Gross Receipts Taxes imposed under the current law. This change will be effective July 1, 2021.

New Mexico will also move to a destination-based sourcing regime for sales of goods and services effective July 1, 2021. In-state and out-of-state sellers will now be taxed at the rates in effect in the jurisdictions where the goods and services are delivered, rather than the seller’s business location.


In accordance with Senate Bill 50 passed by the Florida legislation, and signed by Governor DeSantis on April 21, 20221, Florida is repealing it’s “bracket system” and will require dealers to use traditional rounding conventions to calculate sales taxes. The new rounding algorithm must meet the following requirements:

  1. The tax must be carried to the third decimal place
  2. The tax must be rounded to the whole cent using a method that rounds up to the next cent whenever the third decimal place is greater than four.

This change is effective July 1, 2021.
