Fontana Sales Tax: Rate Breakdown, Seller Rules, and Penalties

The sales tax rate in Fontana, California is 8.75%. That applies to most retail purchases of physical goods made within city limits, and it combines California’s statewide base rate with two local add-ons. The California Department of Tax and Fee Administration (CDTFA) keeps the official rate schedule and updates it when new local measures take effect.1California Department of Tax and Fee Administration.

How the 8.75% Breaks Down

The rate has three parts. California’s statewide base is 7.25%, and every sale in the state starts there. On top of that, Fontana shoppers pay two district taxes approved by local voters.

  • Measure I (0.50%): San Bernardino County’s half-cent transportation sales tax, first approved by voters in 1989 and extended in 2004. The San Bernardino County Transportation Authority administers the revenue and returns it to the subregion that generated it.2San Bernardino County Transportation Authority. Measure I Funding
  • Measure T (1.00%): A Fontana-specific transaction and use tax that funds the city’s general fund, including police, fire, and infrastructure.3City of Fontana. Measure T

Before Measure T, Fontana sat at 7.75%, which was the county floor and the lowest rate in San Bernardino County.3City of Fontana. Measure T The city measure brought Fontana in line with many of its neighbors.

What You Pay Tax On

California sales tax applies to retail sales of tangible personal property, meaning physical goods you can touch.4California Department of Tax and Fee Administration. Revenue and Taxation Code 6051 – Imposition and Rate of Sales Tax In practical terms, that covers clothing, furniture, electronics, building materials, and similar items sold at Fontana stores. Digital products can be taxable depending on how they’re delivered; software on a physical disc is treated differently than the same software downloaded.

Several common purchases are exempt. Cold groceries bought for home consumption are generally not taxed, though heated or prepared food sold for immediate consumption is. Prescription medication dispensed by a licensed pharmacist is exempt.5California Department of Tax and Fee Administration. Sales and Use Tax Regulations Article 8 Professional services that don’t produce a physical good, like legal or accounting work, are not subject to sales tax at all.

Online and Out-of-State Purchases

If you buy something from an out-of-state seller who doesn’t charge California sales tax, you owe California use tax at the same 8.75% rate.6California Department of Tax and Fee Administration. California Use Tax The use tax exists so that buying across state lines or from a non-collecting online retailer doesn’t become a way around the sales tax.

Most online purchases already include the tax at checkout. Out-of-state retailers with more than $500,000 in sales into California during the current or prior calendar year must register with the CDTFA and collect the tax themselves.7California Department of Tax and Fee Administration. Use Tax Collection Requirements Based on Sales into California If a seller didn’t collect it, the obligation falls on you. If you paid another state’s sales tax on the same purchase, you can claim a credit for that amount so you aren’t taxed twice.

If You Sell in Fontana

Any business selling or leasing tangible personal property in Fontana needs a California seller’s permit before its first taxable sale. The requirement covers sole proprietors, corporations, partnerships, and LLCs, and applies to both retail and wholesale activity.8California Department of Tax and Fee Administration. Frequently Asked Questions – Seller’s Permit There is no fee to register, and you can apply online through the CDTFA.

Once you have a permit, you’re responsible for collecting the full 8.75% on taxable sales, filing returns on time, and holding valid resale certificates for wholesale transactions. Accepting a resale certificate without verifying the buyer’s permit number can leave you liable for the uncollected tax.

The CDTFA assigns your filing frequency when you register, based on expected taxable sales. Most small businesses file quarterly; higher-volume sellers file monthly.9California Department of Tax and Fee Administration. Filing Dates for Sales and Use Tax Returns Quarterly returns are due:

  • January–March: due April 30
  • April–June: due July 31
  • July–September: due October 31
  • October–December: due January 31

Monthly filers owe their return by the last day of the following month. If a due date falls on a weekend or state holiday, the deadline moves to the next business day. You must file even if you had no sales for the period. Businesses averaging $17,000 or more per month in sales tax liability are placed on a quarterly prepayment schedule, with estimated payments due by the 24th of each month inside the quarter.10California Department of Tax and Fee Administration.

Online payments must be made by midnight Pacific time on the due date. Electronic Funds Transfer payments have an earlier cutoff of 3:00 p.m. Pacific.9California Department of Tax and Fee Administration.

Penalties for Filing or Paying Late

A late filing or late payment carries a 10% penalty on the tax due.12Justia Law. California Revenue and Taxation Code 6591-6597 – Interest and Penalties That 10% is the ceiling for any single return period, so a late filing combined with a late payment doesn’t stack to 20%, but it still grows quickly on larger bills.

Interest accrues on top of the penalty from the original due date until you pay. California sets the rate by taking the federal underpayment rate and adding three percentage points, adjusted every six months.13California Department of Tax and Fee Administration. Regulation 1703 Businesses on the quarterly prepayment schedule face a separate 6% penalty for missing a required prepayment, which rises to 10% if the CDTFA finds the failure was due to negligence or intentional disregard of the law.

Filing on time, even a zero-dollar return, keeps your account clean and takes only a few minutes online.
