which tax rules are mandatory ?

Hi I am trying to define a tax setup (taxes tab, county, state etc)  and when I try to enable the check box "apply tax to transactions' I get a whole bunch of errors as below.

Define either a default tax formula or a tax rule for the rule type: Determine Taxable Basis.
Define either a default tax status or a tax rule for the rule type: Determine Tax Status.
Define either a default tax registration or a tax rule for the rule type: Determine Tax Registration.
Define either a default place of supply or a tax rule for the rule type: Determine Place of Supply.
