The sales tax rate in Pasadena is 10.50%, effective April 1, 2025, after Los Angeles County voters approved a measure that raised the previous 10.25% rate.1California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rates That rate applies to most purchases of physical goods within the city, whether you buy at a Colorado Boulevard storefront or order online for delivery to a Pasadena address.
What Makes Up the 10.50% Rate
The rate is a stack. California’s statewide base is 7.25%, which funds the state general fund, local public safety, and other baseline operations.2California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rate Information The remaining 3.25% comes from district taxes layered on by Los Angeles County and the City of Pasadena through voter-approved measures.
Two components are easy to identify. Measure I, the Pasadena City Services Measure approved in November 2018, adds 0.75% and generates roughly $21 million per year for the city’s general fund, covering fire stations, police staffing, street repairs, homelessness programs, and after-school services. In November 2024, LA County voters passed Measure A, which replaced the former Measure H (a 0.25% countywide homeless services tax) with a new 0.50% countywide tax.3California Department of Tax and Fee Administration.

The rest of the district portion funds county transportation and other regional programs.
What Gets Taxed in Pasadena
California’s sales tax applies to retail sales of tangible personal property, meaning physical items you can touch, move, or measure.4California Legislative Information. California Revenue and Taxation Code 6051 In Pasadena, that covers furniture, electronics, clothing, auto parts, and most anything else that comes home in a bag or a box.
Professional services are not taxed. Legal advice, accounting, consulting, and haircuts fall outside sales tax because they don’t involve the sale of physical goods. When a service comes with a physical product attached, such as a mechanic replacing a part, the part itself is taxable even when the labor is not.
Software has its own quirk. California currently taxes prewritten software only when it’s delivered on physical media like a disc or USB drive. Downloaded software, browser-based SaaS, and custom-built software are not taxed under existing law.5Legislative Analyst’s Office. The 2026-27 Budget: Sales Tax on Prewritten Software The Governor has proposed extending sales tax to downloaded and cloud-based prewritten software starting January 1, 2027, so this exemption may not last.
One thing California does not offer: sales tax holidays. Unlike Florida, Texas, and Missouri, which waive tax on school supplies or clothing for a few days each year, California charges the full rate year-round.
Groceries and Prescriptions
Groceries are the biggest exemption most Pasadena residents will encounter. Food products bought for home preparation, including produce, meat, dairy, bread, and canned goods, are exempt from sales tax.6California Legislative Information. California Revenue and Taxation Code 6359 The exemption disappears the moment food is sold heated, served as a meal, eaten on the seller’s premises, or sold through a vending machine. A cold sandwich from a grocery deli is exempt; the same sandwich heated up and served on a plate is taxable. Carbonated beverages and alcoholic drinks are always taxable, even at a grocery store.7California Department of Tax and Fee Administration.

Prescription medications dispensed by a licensed pharmacist are exempt, along with medicines furnished directly by a physician, dentist, or health facility for treatment.8California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6369 Over-the-counter drugs and dietary supplements do not qualify.
Use Tax on Out-of-State Purchases
When you buy something from an out-of-state seller that doesn’t collect California tax, common with smaller online retailers, you owe use tax at the same 10.50% rate. Use tax exists to prevent an end-run around local sales tax by purchasing from sellers outside California.9California Department of Tax and Fee Administration. California Use Tax, Good for You. Good for California
How you report it depends on your situation. Business owners with a seller’s permit include use tax on their regular sales and use tax return. Individuals can report it on their California income tax return using the use tax worksheet, or pay directly through the CDTFA’s online portal. Most consumers ignore this obligation on small purchases, but on big-ticket items like equipment or furniture bought out of state, the bill adds up fast, and the CDTFA does cross-reference data.
Getting a Seller’s Permit
Before collecting a single dollar in sales tax, any business selling tangible goods at retail in Pasadena needs a California seller’s permit from the CDTFA. The permit is free with no application fee, though the CDTFA may require a security deposit to cover potential unpaid taxes if the business later closes.10California Department of Tax and Fee Administration. Obtaining a Sellers Permit The requirement applies to sole proprietors, corporations, partnerships, and LLCs alike. Even wholesalers who don’t sell directly to consumers need one.
Selling only during a temporary event, such as a holiday market or rummage sale lasting 90 days or fewer, still requires a temporary seller’s permit for that location. Registration is handled online through the CDTFA’s website.
Filing Sales Tax Returns
The CDTFA assigns each business a filing frequency, either monthly, quarterly, or annually, based on the business’s reported or anticipated tax liability.11California Department of Tax and Fee Administration. Filing Dates for Sales and Use Tax Returns Most new businesses start on a quarterly schedule. Higher-volume operations with an average monthly tax liability of $17,000 or more must make prepayments during each quarter in addition to filing returns.12California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6471
Returns are filed through the CDTFA’s online portal.13California Department of Tax and Fee Administration. State, Local, and District Sales and Use Tax Return The return asks for total gross sales, then breaks out deductions such as nontaxable food sales and sales for resale backed by valid resale certificates to arrive at the taxable amount.14California Department of Tax and Fee Administration. Short Form – Sales and Use Tax Return The system calculates what you owe and takes payment by ACH transfer, credit card, or mailed check.
Penalties for Filing or Paying Late
Missing a deadline gets expensive quickly. The CDTFA imposes a 10% penalty for filing a return late and a separate 10% penalty for paying late. If you do both, filing late and paying late, the combined penalty is capped at 10% of the tax due for that period rather than stacking to 20%.15California Department of Tax and Fee Administration. Trouble Paying Taxes Interest starts accruing the moment your payment is late, and unlike the penalties, there’s no cap. Partial payments reduce the balance that accrues interest, so paying whatever you can as early as possible matters even when you can’t cover the full bill.
Record-Keeping Requirements
California requires every business with a seller’s permit to keep sales tax records for at least four years.16California Department of Tax and Fee Administration. Sales and Use Tax Regulations – Regulation 1698 That means receipts, resale certificates, exemption documentation, register tapes, and any digital records your point-of-sale system generates. If your POS system overwrites data on a rolling basis, export and preserve that data separately before it disappears.
Four years is the minimum. If the CDTFA suspects underreporting or fraud, longer lookback periods apply, and there is no statute of limitations when a return was never filed. Keeping organized records for at least six years is the safer bet, especially in cash-heavy industries where audits are more common.
What Triggers a Sales Tax Audit
The CDTFA doesn’t audit randomly as often as people assume. The agency uses data analytics to flag returns that look unusual compared to industry norms. Common red flags include reported sales that seem low for the business type, credit card processing receipts that exceed the sales reported on tax returns, a sudden year-over-year drop in reported figures, and mismatches between federal income tax filings and CDTFA returns. Referrals from other agencies matter too. An IRS audit or a state employment audit can prompt the CDTFA to take a closer look.
When an audit begins, the CDTFA typically requests sales records, bank statements, resale certificates, and exemption documentation covering the audit period. The single most common problem auditors find is missing or expired exemption certificates for sales made without collecting tax. If you sold goods tax-free based on a customer’s resale certificate and can’t produce that certificate during an audit, the CDTFA will assess tax on those sales as though they were taxable retail transactions. Keeping a current, organized file of every resale and exemption certificate is the most effective audit defense a Pasadena business can have.
Buying a Pasadena Business: Successor Liability
Purchasing an existing business in Pasadena carries a risk many buyers don’t see coming. Any unpaid sales tax from the previous owner can become your problem. California allows the CDTFA to pursue the new owner for the prior owner’s delinquent sales tax when substantially all business assets change hands. The standard protection is to withhold part of the purchase price in escrow until the CDTFA issues a tax clearance confirming no outstanding liability. Skipping that step, or closing the deal before the clearance comes through, leaves you personally on the hook for someone else’s tax debt. It’s one of the fastest ways to inherit a five-figure liability you didn’t know existed.
