Does OSCMax allow multiple tax rates within a US State?

[markw10]

I live in Colorado and we have multiple tax rates here. I don't charge taxes to anyone outside of the State of Colorado but once they are in the state the rate is 2.9%. Then if they are in the Denver metropolitan area it goes up to around 4.2% or so depending on where they are with transportation and stadium taxes. Then inside the county I'm in it goes up more and then inside the city I'm in even more until it's up to around 9%. The hardest part for me of choosing a shopping cart solution is finding one that supports these multiple tax rates.
I quickly ruled out Virtuemart but am looking at OS Commerce and many derivatives of it such as CubeCart, ZenCart, OSC Max, and CRE Loaded. I have also looked at Storefront.net, Miva, and especially X-Cart.

My question, are these multiple tax rates supported by this or any of these other solutions or even a shopping cart I haven't mentioned. I'm definitely not a programmer and don't know anyone that is so it has to be a out of the box solution when I get the cart or either a simple extension that can be added. I appreciate any help with this.
