subselect

I've got the following SQL Statement that needs some major speed up. The problem is I need to search on two fields, where each of them is calling several sub-selects. Is there a way to join the two fields together so I call the sub-selects only once?

SELECT billyr, billno, propacct, vinid, taxpaid, duedate, datepif, propdesc
FROM trcdba.billspaid
WHERE date(datepif) > '01/06/2009'
AND date(datepif) <= '01/06/2010'
AND custno in
 (select custno from cwdba.txpytaxid where taxpayerno in
  (select taxpayerno from cwdba.txpyaccts where accountno in
   (select accountno from rtadba.reasacct where controlno = 1234567)))
OR custno2 in
 (select custno from cwdba.txpytaxid where taxpayerno in
  (select taxpayerno from cwdba.txpyaccts where accountno in
   (select accountno from rtadba.reasacct where controlno = 1234567)))
