Ok, making it a global setting shouldn't be too hard...  Anything
more fine grained would require data format changes, which would be
bad.

This, however, is "impossible".  It would require changes to the data
formats, which is something I really don't want to do (because it
would make data files incompatible across versions, which is a Bad
Idea).  There is no tax amount stored in an invoice.. it is always
computed from the tax-tables.

For a Bill (as opposed to an Invoice), you could always just add a
"Sales Tax" line-item, since you already know what the amount should
be.
