No. UltraTax CS Express does not have all of the same functionality as UltraTax CS. You should purchase UltraTax CS if you need more than one user, need more than 250 returns a year, need Virtual Office CS, or access to the Oil and Gas module. You should also consider UltraTax CS if you need forms beyond 1040, 1120, and 1065 or if you need to file returns in more than five states.
