Question about Collecting Sales Taxes through OS Commerce?

[markw10]

I live in a suburb of Denver, Co and the way taxes are done here is they vary a lot by location. For example if someone isn't in Colorado I collect no sales taxes. If they are in the state but outside of the Denver metro area in general I collect the flat sales tax rate of 2.9%. Then if they are in the Denver metro depending where they are I have to collection taxes for a stadium tax plus a transporation tax which adds up to around 4.1%. Then if they are in the same county as me they are another .9% of so and then if they are in the same city as me another 3% or so.
Often it is confusing because it's hard to know where the stadium and transportation tax can be. It's not necessarily by city or country in the metro area and some cities if they are in the right area they may be in the same county as me but also could easily not be.
I'm still working on developing my CRE Loaded (OS Commerce based) web site. How would I set up something like this? Unfortunately most places I've gone I've been unable to find much help and maybe there is no solution for this but I know others have to have run into a problem and it seems like there would be solutions.

How about finding a partner living other place or even other country?
