David,

Yes, that sounds like a good idea if we ever had to implement that. It does not seem like we need to at this stage--just using a higher regional tax rate seems to work OK.

This would be a good thing to use the TaxAuthorityAssoc for, and with a new TaxAuthorityAssocType that would represent that the local tax should include the associated tax authority's tax in the taxable amount.

Does that sound about like what you're looking for?

It is very much a nasty practice, but it does seem like there are countries that practice it: a regional tax on top of a national or federal tax. As long as all products would require both national and federal tax, I think we're OK - we can just put in a regional tax at a higher rate. If we run into a situation where some products are charged a federal tax and some not, all are charged a regional tax, and the regional tax is a tax-on-tax, then we'd need to model the tax-on-tax. :)

1.  Does OFBiz support tax on tax?  I just wanted to confirm that
it does not.  Looking at TaxAuthorityServices getTaxAdjustments
method, as it seems to iterate over all the TaxAuthorityRateProduct
in the "filteredList", multiplies each one by the itemAmount, and
then adds them to the list of adjustments.

Yeah, that sounds right. In other words: no, there is not support
right now for charging tax on tax.

Is this a requirement you've run into somewhere? Sounds a bit
nasty... from a business perspective and a technical perspective. ;)

In France a such thing existed. It's called CSG (Contribution Sociale Généralisée or in english something like Social Generalized Contribution). Actually only a part of CSG was really tax on tax.This normally has been corrected but I'm not totaly sure... I can see many other cases where such thing actually exists, they are peculiar cases but they exist. It seems also that at least it exists
in Canada.

That does not mean that I need it...
