Who must collect sales tax

Retailers selling tangible personal property in California are generally required to collect sales tax from customers and remit it to the California Department of Tax and Fee Administration (CDTFA). Remote and marketplace sellers may also have collection obligations under state law; confirm registration and permit requirements before opening or expanding sales.

Registering and permits

  • Obtain a Seller's Permit from the CDTFA to legally collect sales tax; applications and registration details are available on the CDTFA site.[1]
  • Register before you make taxable sales or within the short statutory period after beginning business; check CDTFA instructions for timing.
  • Confirm whether the City of Irvine requires a separate business license or business tax certificate for your trade; the city issues business licensing guidance and forms.[3]
Register with the CDTFA for a seller's permit before collecting sales tax.

Collecting and remitting sales tax

Collect sales tax at the point of sale based on the applicable rate for the location of sale or delivery. Local rates vary by jurisdiction within Orange County; verify Irvine’s combined rate for the store or delivery address before setting your point-of-sale system.

  • Charge the correct state plus local rate to customers; use CDTFA rate lookup resources to confirm current rates for Irvine and specific addresses.[2]
  • Keep accurate sales records and exemption documentation for all tax-exempt sales and resale certificates.
  • File returns and remit payments on the frequency CDTFA assigns (monthly, quarterly, or annually) based on your tax volume.

Penalties & Enforcement

Primary enforcement and audit authority for sales and use tax in Irvine is the California Department of Tax and Fee Administration (CDTFA). The City of Irvine enforces local business licensing and may refer tax collection issues to CDTFA or pursue noncompliance under local business tax ordinances.[1][3]

  • Fine amounts: not specified on the cited CDTFA or City of Irvine pages; see the cited CDTFA pages for guidance on penalties and interest.[1]
  • Escalation: CDTFA may assess additional penalties, interest, and proposed assessments for late payment or underreporting; specific escalation amounts are not specified on the cited pages.[1]
  • Non-monetary sanctions: administrative holds, suspension of the seller's permit, seizure or lien actions, and referral to collections or court actions are possible depending on enforcement outcomes (details not specified on the cited pages).[1]
  • Enforcer and contact: CDTFA handles sales tax enforcement and audits; City of Irvine handles local business licensing. Use the official CDTFA contact pages and the City of Irvine business license contact for complaints or questions.[1][3]
  • Appeals and review: CDTFA provides a protest and appeal process for assessments; specific appeal time limits and procedures are set by CDTFA regulations and are detailed on their site (see cited page for exact deadlines and steps).[1]
  • Defences/discretion: exemptions, resale certificates, and properly documented exceptions are common defenses; local permits or variances may also affect enforcement outcomes.
If penalties or exact fees are needed, consult the CDTFA assessment and penalties pages for precise figures.

Applications & Forms

The primary statewide form is the Seller's Permit application via CDTFA; the City of Irvine provides business license application forms where required. Specific form names and filing fees are published on the CDTFA and City of Irvine sites. If a City form number is not shown on the city page, the city contact will confirm filing requirements.[1][3]
