I am looking to implement the odoo software for my business in Florida. We deal with different tax rates in each county plus a base rate for the state.

For instance; In Escambia county, there is a 1.5% sur-tax added to the 6% state tax. The difficult part is that if the invoice is for more than $5,000, the sur-tax is only charged on the first $5,000 but the base tax is charge on the whole amount.

How would I accomplish this?
