General Tax Rate

David -

From the Help information for Tax Rate:

General > Tax Rate
If zone is a tax band, enter rate. For example, for U.K you would enter 20 (for 20%). Leave as 0 for no tax. At checkout tax is applied to total of goods and shipping.

Is there any way for the Tax Rate to reflect a decimal point?  Like 2.9%?

I am trying to pass on the PayPal fees to the customer.

I have .30 (30 cents) defined in the Rates area (for all weights).
But setting the Tax Rate to 2.9 will give a Tax Rate of just 2%.
