Effective July 1st, 2022, Colorado is imposing a retail delivery fee on all deliveries by motor vehicle to a location in Colorado with at least one item of tangible personal property.

To facilitate collecting this tax, we added the ability to create a flat tax rate definition. Rather than specifying a tax percentage, you now can set a flat rate to be collected.
