Tax
US sales tax is set by states, and often by counties and cities on top, and the rules for prepared food differ from place to place. Many trucks owe a combined state and local rate that depends on where they sell, so confirm your rates and filing schedule with your state revenue department or an accountant.
How the software handles it
Add each rate under Settings, combine them into a tax group per city if needed, and set whether prices include tax or have it added at the window. The tax report totals what you collected by period and by truck, ready to hand to whoever files. GetFoodTruckPOS applies and reports tax; it does not file returns.
