Comment (by scribu):

 Ok, here's an alternative approach:

 Define a new query var, 'business_id' and use the 'request' filter to
 transform it into a 'tax_query':

 {{{
 define( 'MY_TAX_NAME', 'business' );
 define( 'MY_TAX_QV', 'business_id' );

 class My_Tax_Enhancement {

         function init_qv() {
                 $GLOBALS['wp']->add_query_var( MY_TAX_QV );
         }

         function parse_qv( $request ) {
                 if ( isset( $request[MY_TAX_QV] ) ) {
                         $request['tax_query'] = array(
                                 array(
                                         'taxonomy' => MY_TAX_NAME,
                                         'terms' => $request[MY_TAX_QV],
                                 )
                         );
                 }

                 return $request;
         }
 }

 add_filter( 'init', array( 'My_Tax_Enhancement', 'init_qv' ) );
 add_filter( 'request', array( 'My_Tax_Enhancement', 'parse_qv' ) );
 }}}
