The Agoura Hills sales tax rate is 9.75 percent in 2026. That total combines California’s 7.25 percent statewide base rate with 2.50 percent in Los Angeles County district taxes that voters approved for transportation and homeless services. The city itself does not levy a separate municipal sales tax, so every taxable retail purchase inside city limits is charged at the same 9.75 percent, and businesses collect it for the California Department of Tax and Fee Administration (CDTFA).
District taxes vary across Los Angeles County, so a storefront a few blocks across a city line can carry a different rate. If you operate near a boundary, confirm your exact rate using the CDTFA’s online tax rate lookup tool before you program your register.
What Gets Taxed and What Does Not
California sales tax applies to tangible personal property, which the Revenue and Taxation Code defines as anything that can be seen, weighed, measured, felt, or touched.1California Department of Tax and Fee Administration. Revenue and Taxation Code 6016 – Tangible Personal Property Clothing, electronics, furniture, appliances, and building materials all qualify. Labor charges for creating a new product are taxable too. Pure service labor, such as consulting or repair work that doesn’t produce a new item, generally is not.
Several categories are exempt. Most grocery food for home consumption is not taxed, including produce, dairy, meat, bread, cereals, and canned goods. Food sold heated or ready-to-eat, carbonated beverages, and restaurant meals are taxable.2California Department of Tax and Fee Administration. Sales and Use Tax Regulations – Article 8 Prescription medicines are also exempt under Revenue and Taxation Code Section 6369.
Digital Products
California takes a narrow approach to digital goods. Prewritten software delivered on a disc or USB drive is taxable. Downloaded software, streaming subscriptions, e-books, and digital music are generally not subject to sales tax.3Legislative Analyst’s Office. The 2026-27 Budget: Sales Tax on Prewritten Software If you sell the same product in both physical and digital form, only the physical copy triggers tax.
Resale Certificates
If you buy inventory to resell, you can skip paying tax at wholesale by giving your supplier a valid resale certificate (CDTFA-230). The certificate must include your seller’s permit number, a description of the property, and your signature confirming you will resell the goods before putting them to personal use. Misusing a resale certificate to avoid tax on items you actually keep carries a penalty of 10 percent of the unpaid tax or $500, whichever is greater, on top of the tax itself.4California Department of Tax and Fee Administration.

Use Tax on Out-of-State Purchases
Use tax is California’s backstop for purchases that escape sales tax. Buy a taxable item from an out-of-state seller that doesn’t collect California tax and you owe use tax at the same 9.75 percent rate directly to the state. The CDTFA describes use tax as a companion to sales tax, keeping out-of-state retailers from undercutting Agoura Hills businesses on price alone.5California Department of Tax and Fee Administration. California Use Tax
Most large online retailers now collect California tax automatically. Smaller vendors, private-party sales of vehicles or equipment, and items bought while traveling can still leave you with a use tax bill. The easiest way to report use tax on personal purchases is on your California income tax return.5California Department of Tax and Fee Administration. California Use Tax Business owners with a seller’s permit report use tax on their regular CDTFA returns.
Getting a Seller’s Permit
Any business selling taxable goods in Agoura Hills needs a California seller’s permit before making its first sale. The permit is free, though the CDTFA may require a security deposit depending on your estimated sales volume and business type.6California Tax Service Center. Get a Seller’s Permit Apply through the CDTFA portal. The application asks for:
- Your Social Security number (corporate officers excluded) and driver’s license number.
- Names and details for all partners, corporate officers, or LLC members.
- Bank account details, personal references, and your estimated average monthly sales, including the taxable portion.
The CDTFA uses your estimated taxable sales to assign a filing frequency. Temporary and seasonal sellers, including vendors at farmers’ markets or craft fairs, still have to register before they start selling.6California Tax Service Center. Get a Seller’s Permit
Filing Returns, Penalties, and Records
The CDTFA assigns each registered business a filing frequency based on reported or expected taxable sales: monthly, quarterly, quarterly with prepayment, yearly, or fiscal yearly.7California Department of Tax and Fee Administration. Filing Dates for Sales and Use Tax Returns Higher-volume sellers file more often. Returns and payments go through the CDTFA’s online portal, which generates a confirmation number as your proof of filing.
Miss a deadline and you face a 10 percent penalty on unpaid tax, plus a separate 10 percent penalty if you also file the return late. Those two penalties are capped at a combined 10 percent of the tax due for any single return period.8Justia Law. California Revenue and Taxation Code 6591-6597 Interest runs on top of penalties at the federal underpayment rate plus three percentage points, calculated monthly from the original due date until you pay.9California Department of Tax and Fee Administration. Regulation 1703
Keep all sales and use tax records for at least four years. That means invoices, exemption and resale certificates, general ledgers, sales journals, and point-of-sale data. If your POS system overwrites data before the four-year mark, export and store it separately. Hold records longer if you’re being audited or disputing a determination, until that matter is fully resolved.10California Department of Tax and Fee Administration. Sales and Use Tax Records – Retaining Records
If an audit produces an assessment you disagree with, you have 30 days from the mailing date of the Notice of Determination to file a written petition for redetermination identifying the disputed amounts and your reasons.11California Department of Tax and Fee Administration. Appeals Procedures – Sales and Use Taxes Miss that 30-day window and the assessment becomes final and immediately payable.
Buying an Existing Business in Agoura Hills
This is where buyers get burned. Purchase a business or its inventory from an owner with unpaid sales tax and you can inherit the debt. Under Revenue and Taxation Code Section 6812, a purchaser who fails to withhold enough from the purchase price to cover the seller’s outstanding tax liability becomes personally responsible for that amount, up to the total purchase price.12California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6812
Protect yourself by requesting a tax clearance certificate from the CDTFA before closing. Once the CDTFA receives your written request, access to the former owner’s records, and notice of the sale date, it has 60 days to either issue the certificate or tell you the amount that must be paid first.12California Department of Tax and Fee Administration. Sales and Use Tax Law – Section 6812 If the CDTFA misses that 60-day window, you’re released from withholding obligations.
Manufacturing and R&D Partial Exemption
Manufacturers and research firms in Agoura Hills can claim a partial sales tax exemption on qualifying equipment purchases. The business must be primarily engaged (50 percent or more of activity) in manufacturing, processing, fabricating, refining, recycling, or certain biological and physical science R&D. The equipment must have a useful life of more than one year, cost $5,000 or more, and be used in the qualifying activity.13California Department of Tax and Fee Administration. Tax Guide for Manufacturing, and Research and Development Equipment Exemption The exemption cuts the tax rate by 3.9375 percent on eligible purchases and runs through June 30, 2030. Equipment used primarily for administration, marketing, or storage of finished goods does not qualify.
Remote Sellers Shipping Into Agoura Hills
Businesses outside California that sell into Agoura Hills must register with the CDTFA and collect use tax once they exceed $500,000 in California sales during the preceding or current calendar year.14California Department of Tax and Fee Administration. Use Tax Collection Requirements Based on Sales into California California has no transaction-count threshold; the $500,000 revenue figure is the sole trigger. Once a remote seller crosses it, they collect at the buyer’s local rate, which means 9.75 percent for Agoura Hills customers.
A remote seller already shipping into California without collecting tax, and not yet contacted by the CDTFA, may qualify for the Out-of-State Voluntary Disclosure Program, which limits the look-back period to three years and can waive late-filing and late-payment penalties.15California Department of Tax and Fee Administration. Out-of-State Voluntary Disclosure Program Businesses that have previously held a seller’s permit, or have already been contacted by the CDTFA, don’t qualify.
