TAX INFORMATION BULLETIN
The quarterly Tax Information Bulletin (TIB) includes articles on the application of law to specific types of
transactions, announcements about new and revised publications, and other articles of interest. You can find
current TIBs on our website at www.cdtfa.ca.gov/taxes-and-fees/tax-bulletins.htm. Sign up for our CDTFA updates

FREE CLASSES AND SEMINARS
We offer free online basic sales and use tax classes including a tutorial on how to file your tax returns. Some classes are
offered in multiple languages. If you would like further information on specific classes, please call your local office.
WRITTEN TAX ADVICE
For your protection, it is best to get tax advice in writing. You may be relieved of tax, penalty, or interest charges that
are due on a transaction if we determine that we gave you incorrect written advice regarding the transaction and
that you reasonably relied on that advice in failing to pay the proper amount of tax. For this relief to apply, a request
for advice must be in writing, identify the taxpayer to whom the advice applies, and fully describe the facts and
circumstances of the transaction.
For written advice on general tax and fee information, please visit our website at www.cdtfa.ca.gov/email to email
your request.
You may also send your request in a letter. For general sales and use tax information, including the California
Lumber Products Assessment, or Prepaid Mobile Telephony Services (MTS) Surcharge, send your request to:
Audit and Information Section, MIC:44, California Department of Tax and Fee Administration, P.O. Box 942879,
Sacramento, CA 94279-0044.
For written advice on all other special tax and fee programs, send your request to: Program Administration Branch,
MIC:31, California Department of Tax and Fee Administration, P.O. Box 942879, Sacramento, CA 94279-0031.
