Taxation and Finance California 4 Minutes Read ยท published February 02, 2026 Flag of California

Businesses operating in Los Angeles, California must register to collect state sales and use tax and also comply with the City of Los Angeles business tax rules. This guide explains where to register, which permits and certificates are required, how to collect and remit sales tax, typical compliance steps, and where to get official help. It addresses both the California seller's permit requirement and the City of Los Angeles Business Tax Registration Certificate so owners know which agency enforces each obligation and how to respond to notices or audits.

Who must register

Any person or business selling tangible personal property in California or making taxable sales in Los Angeles must obtain a seller's permit from the California Department of Tax and Fee Administration (CDTFA) and register with the City of Los Angeles Office of Finance for local business tax where applicable. See the city and state registration pages for application links and online services.[1][2]

How to register and collect

  • Obtain a California seller's permit (CDTFA) to collect state and local sales tax; register online via CDTFA Online Services.[2]
  • Apply for the City of Los Angeles Business Tax Registration Certificate (BTRC) with the Office of Finance if your activity is taxable under municipal rules.[1]
  • Set up point-of-sale systems to apply the correct combined rate (state plus local district taxes) and keep itemized sales records.
  • File sales and use tax returns and remit collected taxes by the deadlines specified by CDTFA; frequency depends on tax liability and is shown in your registration account.
  • Update registrations when you move, open additional locations, change ownership, or cease operations.
Register with both the state and the city before opening for business.

Penalties & Enforcement

Sales tax collection and remittance are enforced by the California Department of Tax and Fee Administration (state) for sales and use tax, and by the City of Los Angeles Office of Finance for local business tax and registration compliance. Each agency may audit, assess tax, and impose penalties or interest for late payment or noncompliance. Where exact penalty amounts or scales are not reproduced on the cited municipal page or linked state registration page, those figures are not specified on the cited page and you should consult the enforcing agency directly.[1][2]

  • Monetary fines and interest: not specified on the cited city page; see CDTFA account notices for state penalties and interest details.[2]
  • Escalation: first notices typically request payment and filing; repeat or continuing noncompliance may lead to higher assessments, levies, or enforced collection (specific escalation schedules not specified on the cited page).
  • Non-monetary sanctions: assessments, administrative holds, license suspension, liens, or referral to collections/court actions may be used by the enforcing agency.
  • Enforcers and complaints: CDTFA enforces state sales/use tax; City of Los Angeles Office of Finance enforces business tax and registration. Use the official contact and complaint pages linked in Help and Support / Resources below.
  • Appeals and review: appeal routes exist through administrative review with the agency that issued the assessment; time limits for filing appeals or protests are provided by the issuing agency and are not specified on the cited city page.
If you receive a notice, respond promptly and preserve sales records for the covered period.

Applications & Forms

The main applications are the California seller's permit (apply via CDTFA Online Services) and the City of Los Angeles Business Tax Registration Certificate application on the Office of Finance site. Fees, form numbers, and precise submission instructions are published on those official pages; if a specific form number or fee is not shown on the cited municipal page, it is not specified on the cited page.[1][2]

Action steps for new businesses

  • Confirm whether your sales are taxable in California and obtain a seller's permit from CDTFA before making taxable sales.[2]
  • Set up accounting and point-of-sale systems to collect the correct tax and keep clear records for audits.
  • Remit taxes and file returns by the deadlines communicated via your CDTFA account and city notices to avoid penalties.
Keeping accurate sales records is the single most important action to reduce audit risk.
