Learn what the California Department of Tax and Fee Administration handles, including seller's permits, sales and use tax, filings, and notices.
The California Department of Tax and Fee Administration, abbreviated CDTFA, is the state agency that administers California sales and use tax and numerous special tax and fee programs. Businesses commonly interact with CDTFA to register for a seller's permit, file returns, make payments, update an account, respond to a notice, or close a permit.
CDTFA's best-known responsibility is California sales and use tax. It also administers various special taxes and fees covering particular products, industries, or activities. Depending on the business, accounts can involve fuel, tobacco, cannabis, environmental fees, lumber products, lead-acid batteries, covered electronic waste, and other programs.
An ordinary seller's permit does not automatically satisfy every special tax or fee registration. CDTFA's online registration asks about business activities and identifies accounts that may be required. City business licenses, professional licenses, health permits, and federal registrations remain separate.
Common events include:
Registration should occur before taxable selling activity begins when a permit is required. CDTFA states that individuals and entities can need seller's permits, and wholesalers may need them even when their sales are for resale.
CDTFA generally handles transaction taxes and special fee programs. The California Franchise Tax Board generally administers personal income tax and entity income or franchise taxes. The Employment Development Department generally administers state payroll tax reporting, unemployment insurance, disability insurance, and related employer programs.
For example, a California LLC retailer might file Form 568 and pay annual LLC tax to FTB, file sales-and-use-tax returns with CDTFA, and file payroll reports with EDD. These obligations can exist at the same time and use different account numbers, forms, portals, and due dates.

Paying one agency does not create a credit with another. A clean chart of accounts should keep sales-tax payable, payroll-tax liabilities, and income-tax payments separate.
CDTFA assigns filing requirements based on the account and circumstances. A sales-and-use-tax account may file annually, quarterly, monthly, or with prepayments. Businesses should follow the frequency and deadlines displayed in their online account. A zero-sales period can still require a return.
A CDTFA notice should be matched to the account number, period, tax or fee program, and response date. Compare it with filed returns, payment confirmations, sales records, exemption documentation, and correspondence. Do not assume the notice is an income-tax notice or respond through FTB.
If the proposed amount is disputed, CDTFA offers formal processes such as a petition for redetermination, claim for refund, and requests for certain penalty relief. Deadlines and procedural requirements matter. Professional help should be considered early when records are incomplete, multiple periods are involved, or the business disagrees with the agency's classification.
Retain permits, registration confirmations, returns, payment records, sales journals, invoices, point-of-sale exports, exemption and resale certificates, purchase invoices, marketplace statements, shipping records, and correspondence. Records should connect reported totals back to the general ledger.
Permit information should be kept current. When ownership changes, the new owner may need a new permit. When a business closes, it should file required final returns, pay balances, and close accounts properly. Simply stopping sales does not necessarily close the filing obligation.
Check CDTFA requirements before launching a new product, opening a location, attending a temporary event, adding online sales, buying a business, changing ownership, entering a special-fee industry, or closing operations. A taxability review can prevent point-of-sale settings from repeating the same error across hundreds of transactions.

What does CDTFA stand for?
California Department of Tax and Fee Administration.
Is CDTFA the California IRS?
No. California divides responsibilities among agencies. CDTFA handles sales/use tax and special taxes and fees; FTB handles income and franchise taxes; EDD handles state employment taxes and related programs.
Is a CDTFA seller's permit the same as a business license?
No. A seller's permit authorizes and tracks sales-and-use-tax activity. Local and industry-specific licenses may also be required.
What should I do with a CDTFA notice?
Identify the account, program, period, amount, and deadline; compare the notice with returns and proof of payment; then respond through the correct procedure. Do not ignore it.
