It is easy:

set the values in columns B and C as percents. Then D would have something
like:
=(1+B1+C1)*A1

With this set-up you can remove a column B or C tax just by setting the
value to zero.

I have 4 columns, A1-item, B1-tax, C1-tax, D1- Total. Some items are taxable
on both, others only on 1, is there a way to automatically charge 1 or 2
taxes on the total.
