This guide explains what the sales tax is in San Bernardino County, California, and why the number changes from city to city. You’ll also learn the main parts of the rate, the highest and lowest totals, and what businesses must do to collect and file correctly.
Why your sales tax can look different
Imagine you buy the same item in two places in the county—your receipt can show different tax. That’s because California adds a base state rate, San Bernardino County adds its county rate, and then cities and special districts can add more.
The quick answer for the county
From available county data, San Bernardino County’s maximum total sales tax rate is 10.5%.
At the same time, the county-wide rate is:
- County sales tax rate: 0.25%
- Base California sales tax: 6% (state base)
So, before city or special district additions, the starting point is 6.25% (6% + 0.25%).

Highest and lowest city totals
The highest total shown for San Bernardino County cities is 10.5%.
The lowest total shown for combined rates in the county is 7.75%.
Because the county includes many jurisdictions, “lowest” and “highest” can depend on which city plus special district applies. Below are examples of totals that appear in the published city tables.
Cities with the highest total rate
Cities shown at 10.5% include:
- Chino
- Chino Hills
Cities with the lower end total rate (examples)
Cities shown at 7.75% include examples such as:
- Fontana (listed at 8.75% in one table, but not the low end)
- Rancho Cucamonga (listed at 7.75%)
In short, the county’s highest totals reach 10.5%, while some cities fall closer to 7.75% when there are fewer additional local add-ons.
Which cities have which totals
Here are example totals from the city tables shown in the sources (not every city is listed there, but the pattern is clear: city and special district rates change the total).
| City example | Total sales tax rate | What this means |
|---|---|---|
| San Bernardino | 8.75% | City + county + state + possible special district |
| Ontario | 8.75% | Often county base plus local additions |
| Fontana | 8.75% | Local city tax adds to the base |
| Victorville | 8.75% | City tax pushes total above 7.75% |
| Rancho Cucamonga | 7.75% | Close to the county’s low end |
| Chino | 10.5% | Highest local add-on shown in the table |
| Chino Hills | 10.25% or 10.5% (varies by table) | Different local district setup can raise totals |
Note on differences
Published tables can show slightly different local totals depending on whether a city also includes a special district for that area.
Components that make up the total rate
A total sales tax rate in San Bernardino County is built like a sandwich:
- State tax (base)
- County tax

- Special district additions can raise the total further

When rates were last updated
The county sales tax rate data is shown as last updated March 2026 in the cited material.
How the maximum compares to other counties nationwide
One source reports that San Bernardino County’s maximum sales tax rate of 10.5% is:
- Higher than 94% of counties nationwide
- Higher than 93% of California counties
So, the maximum total in San Bernardino County is very high compared with most of the country.
Historical changes that influenced rates
Sales tax rates change due to:
- Local ballot measures (voter-approved increases to fund services)
- Economic needs (cities or the county needing revenue during downturns)
- Legislative and allocation shifts (state or local rules changing how funds are structured)
In practice, this means residents may see periodic increases tied to local programs like transportation, public safety, and community services.
Exemptions and special cases shoppers often ask about
In California, common exemptions include:
- Groceries: essential grocery items like fresh produce, dairy, and bread are generally exempt
- Prescription medicines: prescribed medication is generally exempt
- Medical equipment: some medically necessary items may qualify when prescribed or documented
- Certain residential utilities: some utilities (like electricity and natural gas for residential use) are generally exempt
This matters because the “sales tax” you see is only applied to taxable purchases. Some essentials may not add tax.
Sales tax holidays
California does not have a statewide sales tax holiday. That means San Bernardino County generally follows the state rule—no broad “tax-free” period for typical purchases.
Local exceptions can happen only in narrow cases, but they are not the usual system.
Business responsibilities in San Bernardino County
Businesses that sell to customers in San Bernardino County generally must:
- Collect sales tax on taxable sales at the correct local rate
- Remit collected tax to the California Department of Tax and Fee Administration (CDTFA)
- File returns on the correct schedule (monthly, quarterly, or annually depending on sales volume)
Physical nexus vs economic nexus
California uses two common ways to trigger tax collection duties:
| Type | What it means | Example |
|---|---|---|
| Physical nexus | Tangible presence in the state | Store, warehouse, office, or employees in California |
| Economic nexus | Sales volume/transaction threshold | Selling enough into California even without a local office |
Seller’s permit process basics
To legally collect sales tax, businesses typically need a seller’s permit from the CDTFA. The application is completed online through the CDTFA website.
How businesses manage accuracy and efficiency
Sales tax can be complex because rates depend on the exact address, city, and sometimes special district. Common best practices include:
- Use correct address lookups (ZIP codes can cross jurisdictions)
- Keep records of taxable sales and exemptions
- File on time to avoid penalties
- Use tax management tools to reduce mistakes when city/district rates change

- With city and special district add-ons, totals in the county can range from about 7.75% up to 10.5%.
