Work on the original CADE, designed to replace the Individual Master File (IMF) system, was begun in 2000 and stopped in 2009.
Under the current system, processing tax returns can take as long as one week and taxpayers have to wait between 14 and 35 days for the IRS to deposit their refund or mail them a check.
CADE will be capable of superior security and fraud protection mechanisms with automated detection of tax return errors and inconsistencies.
CADE will also provide superior in-house functionality for the IRS to access information, reports, compliance issues, notices, and revenue accounting.
Taxpayers who do not have established bank accounts to receive direct deposit will still have a minimum of one week wait time for checks by mail.
