The sales tax rate in Fremont, California is 10.25%, effective April 1, 2026. That means a $100 taxable purchase rings up at $110.25. The rate combines California’s 7.25% statewide base with 3% in district taxes approved by Alameda County voters.
How the 10.25% Rate Is Built
Every city in California starts from the same 7.25% statewide base, which is set by Revenue and Taxation Code Section 6051.1California Department of Tax and Fee Administration. California Revenue and Taxation Code 6051 – Imposition and Rate of Sales Tax What pushes Fremont to 10.25% is a stack of Alameda County district taxes layered on top.
Measure BB adds a half-cent for countywide transportation improvements. Measure C adds another half-cent for children’s healthcare, early education, and childcare access, running through fiscal year 2040–2041. Additional district taxes support BART operations and other Alameda County transportation programs. Each measure was passed by voters with its own expiration date and oversight rules, so the combined rate can change as measures lapse or new ones are approved. The CDTFA publishes current rates for every California city on its rates page.2California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rates
What’s Taxable in Fremont
California’s default rule is that retail sales of tangible personal property are taxable. If you can see it, touch it, or weigh it, and no specific exemption applies, the 10.25% rate attaches. Electronics, furniture, clothing, sporting goods, appliances, and most other physical items all qualify.
The main exemptions cover essentials. Groceries bought for home consumption, including produce, dairy, meat, and bread, are generally exempt under Revenue and Taxation Code Section 6359.3California Department of Tax and Fee Administration. Common Sales and Use Tax Nontaxable Sales and Partial Exemptions Prepared food, hot food, and anything sold for on-premises consumption, like a restaurant meal, remain taxable. Prescription medicines and certain medical devices are also exempt under Section 6369.4California Department of Tax and Fee Administration. Regulation 1591
Digital Products and Software
California treats digital goods differently from most states. Software downloads, eBooks, mobile apps, streaming subscriptions, and other products delivered entirely over the internet are generally not taxable here. Cloud-based software subscriptions (SaaS) follow the same logic and are also not taxable.
The catch is delivery method. If the seller includes any physical medium with the download, like a flash drive backup or a printed manual, the entire transaction becomes taxable.5California Department of Tax and Fee Administration. Internet Sales (Publication 109) Nontaxable Sales
Use Tax on Out-of-State and Online Purchases
When you buy something from an out-of-state or online seller that doesn’t collect California sales tax, you owe “use tax” at the same 10.25% Fremont rate. Use tax exists so people can’t dodge sales tax by shopping across the border. Most large online retailers collect California tax automatically now, but smaller sellers, auction purchases, and private-party sales from other states can still leave you with a use tax bill.
Individuals report use tax on their California state income tax return, which includes a worksheet to calculate the amount. The CDTFA also offers a lookup table that estimates use tax based on your income if you don’t want to track every purchase. Businesses that don’t hold a seller’s permit but make more than $10,000 in untaxed purchases in a year must register as a “qualified purchaser” and file an annual use tax return by April 15.6California Department of Tax and Fee Administration.

If You Sell in Fremont: Two Registrations, Not One
Businesses selling in Fremont need to register twice, and skipping either step causes trouble.
First, any business selling or leasing tangible personal property in California needs a seller’s permit from the CDTFA before the first taxable sale. Selling without one is illegal and triggers fines.7California Department of Tax and Fee Administration. Do You Need a California Seller’s Permit? The permit is free and the application runs through the CDTFA website. You’ll provide your Social Security number (or substitute document), driver’s license, bank account details, estimated income, and information for any partners or corporate officers.8California Department of Tax and Fee Administration.

Second, Fremont’s Revenue Division collects a separate business tax from any business operating within city limits. This applies even to businesses physically located outside Fremont that do business inside it. Registration and payment go through the city’s online portal.9City of Fremont, CA Official Website.

Filing Deadlines
Returns and payments go through the CDTFA’s online portal, which handles gross sales reporting, exemption application, and tax calculation. You can pay by ACH debit or credit card.10California Department of Tax and Fee Administration. Online Services – File a Return Most businesses file quarterly, with returns due by the last day of the month after each quarter closes:
- Q1 (January–March): due April 30
- Q2 (April–June): due July 31
- Q3 (July–September): due October 31
- Q4 (October–December): due January 31
If a due date falls on a weekend or state holiday, the deadline moves to the next business day. High-volume retailers may be placed on monthly schedules or required to make prepayments.11California Department of Tax and Fee Administration. Online Services – Return Prepayments
Penalties for Missing a Deadline
California charges a 10% penalty on tax not paid by the due date and a separate 10% penalty for failing to file on time. These are capped at a combined 10% of the tax owed for a single return period, so one late return won’t stack to 20%. Interest accrues on top of the penalty at the federal underpayment rate plus three percentage points, compounded monthly.12Justia. California Code Revenue and Taxation Code 6591-6597 – Interest and Penalties
A harsher penalty applies when a business collects sales tax from customers but keeps it instead of remitting it: 40% of the amount not remitted, on top of the base penalties. The CDTFA treats collected-but-unremitted tax as one of the most serious violations in sales tax administration.
