On the other hand, being certified to do prepare and file taxes does not qualify you to become a paid tax preparer in California. Requirements for becoming CTEC Certified and becoming a paid preparer can be found at http://www.vita-volunteers.org/Become_a_Paid_Tax_Preparer.htm
Even if you are qualified to do taxes for money, you need to pass your certification as a VITA Volunteer for each season to do taxes. No IFs, ANDs, BUTs or WHAT IFs!! If you want to prepare taxes as a VITA Volunteer, you MUST currently be certified.
