I'm sure some back-office bookkeeping functions can be offshored, but others cannot. For instance, in the U.S., certain tax filings and other types of official paperwork require businesses and individuals to give permission to authorities to contact CPAs directly. In addition, tax laws are also very local, including state regulations (50 U.S. states + territories) and sometimes municipal and county regulations. This requires a level of expertise that few overseas-based bookkeepers would be able to work with.
