Selling in Riverside means getting three things right: the correct combined sales tax rate, a state seller’s permit, and on-time returns. The rate is location-specific, not one flat citywide number. The California Department of Tax and Fee Administration (CDTFA) administers all of it, and you can confirm any address on the CDTFA sales and use tax rates page.
This guide gives you the current Riverside sales tax rate, who has to collect it, how to register, what is taxable, and when returns are due. Every number here is verified against a primary source.
What Is the Sales Tax Rate in Riverside City, California?
The combined sales and use tax rate for the City of Riverside is 8.75%, effective for the quarter beginning July 1, 2026, per CDTFA’s official city and county rate table. That figure is California’s 7.25% statewide base plus two voter-approved district taxes. Rates change quarterly, so confirm the current figure before you price anything.
| Component | Rate | Source |
|---|---|---|
| California state rate | 6.00% | CDTFA rate description |
| Mandatory uniform local (Bradley-Burns) rate | 1.25% | CDTFA rate description |
| California statewide base | 7.25% | CDTFA rate description |
| Riverside County district tax (Measure A, RCTC) | 0.50% | CDTFA rates page |
| City of Riverside district tax (Measure Z) | 1.00% | CDTFA rates page |
| Combined City of Riverside rate | 8.75% | CDTFA rates page |
California’s 7.25% base is the highest statewide base rate in the country, according to the Tax Foundation. The Riverside County Transportation Commission (RCTC) tax of 0.50% has applied countywide since July 1, 1989. The City of Riverside’s 1.00% Measure Z tax took effect April 1, 2017, and voters rejected a June 2026 measure that would have raised it to 1.25%, per the City of Riverside.
Rates take effect on January 1, April 1, July 1, and October 1 each year, per CDTFA. Rates are also address-specific: neighboring Riverside County cities like Corona and Moreno Valley can carry different combined rates. Always confirm your exact rate with the CDTFA address lookup and see Commenda’s California sales tax rates guide for the statewide picture.
Do I Need to Collect Sales Tax in Riverside, California?
Yes, if you have physical or economic nexus in California and sell taxable goods delivered to Riverside addresses. Physical nexus comes from an office, store, warehouse, inventory (including Fulfillment by Amazon (FBA) stock stored in California), employees, agents, or sales at trade shows and temporary events. Economic nexus is a pure sales test, described below.
California’s economic nexus threshold is $500,000 in sales of tangible personal property delivered into California in the current or preceding calendar year, effective April 1, 2019, under Assembly Bill 147 (AB 147), per CDTFA. California has no 200-transaction threshold, so transaction count never triggers registration on its own.
Marketplace facilitators such as Amazon collect and remit on behalf of their marketplace sellers under California’s Marketplace Facilitator Act, effective October 1, 2019, per CDTFA. If you cross the threshold, you must also collect the applicable Riverside County and City of Riverside district taxes wherever you are engaged in business.
How Do I Register for a Sales Tax Permit in California (CDTFA)?
Register online through the CDTFA online services portal before making any sales. The seller’s permit is free; CDTFA charges no registration fee, though it may require a security deposit for some applicants, per CDTFA. Gather your details first so the application goes through in one sitting.
| What you need | Why CDTFA asks |
|---|---|
| SSN or EIN | Identifies you or your entity |
| Business entity type and formation details | Confirms your legal structure |
| Estimated monthly sales | Sets your assigned filing frequency |
| Supplier names and addresses | CDTFA verifies your business activity |
| Business bank account information | Used for payments and refunds |
Short-term and event sellers can request a temporary seller’s permit instead of a standard one. For a full walkthrough, see Commenda’s California sales tax permit guide.
Do I Also Need a Riverside City Business Tax Certificate?
Yes, and it is a separate obligation from your seller’s permit. The CDTFA seller’s permit is a free state-level sales tax registration. The City of Riverside Business Tax Certificate, often called a business license, is a separate municipal requirement administered by the City of Riverside, not CDTFA. Most businesses operating in the city need both.
Confirm the current application process and fee schedule directly with the City of Riverside Finance Department, since municipal fees change and vary by business type. Treating the seller’s permit and the business tax certificate as one filing is a common and costly mistake.
Is My Product Taxable in Riverside City?
Most tangible personal property is taxable in California; most services and electronically delivered digital products are not. Clothing is taxable because California has no apparel exemption. Software you download is generally not taxable because no tangible personal property changes hands. The table below sorts the common cases.
| Category | Taxable? | Source |
|---|---|---|
| Clothing, electronics, furniture | Taxable | CDTFA |
| Prepared food, soft drinks, candy | Taxable | CDTFA |
| Prewritten software on physical media | Taxable | CDTFA |
| Groceries for home consumption | Exempt | CDTFA |
| Prescription medicines, certain medical devices | Exempt | CDTFA |
| Electronically delivered software, e-books, streaming | Not taxable | CDTFA |
| Custom software | Generally exempt | CDTFA |
| Standalone services | Generally not taxable | CDTFA |
Services need nuance. Repair labor is generally exempt while the parts you install are taxable. In construction, materials and fabrication labor can be taxable even when installation labor is not. California has no Gross Receipts Tax (GRT) on digital goods, software, or online services, despite what older guides claim.
What Sales Tax Exemptions Apply in Riverside City?
California exempts groceries for home consumption, prescription medicines, certain medical devices, sales for resale, and some sales to the US government, all of which require documentation, per CDTFA. Exemptions are not automatic. You must hold the right paperwork to defend them in an audit.
Buyers purchasing for resale buy tax-free using a resale certificate. As the seller, you must collect and retain a valid resale or exemption certificate to substantiate every exempt sale, per CDTFA. Exemption certificates are generally required per delivery state for each wholesale or resale customer, and California is no exception, though larger customers buying across multiple states can sometimes use a multi-jurisdictional resale certificate instead of a separate one per state. Two traps catch businesses often: nonprofit purchases are not automatically exempt in California, and vitamins and dietary supplements are generally taxable. See Commenda’s California exemption certificate guide for handling certificates correctly.
How Do I File Sales Tax Returns in Riverside City?
File online through the CDTFA portal on the schedule CDTFA assigns at registration. There is no separate City of Riverside sales tax return; the city’s district taxes are reported on the same state return. There is no “Form 401-A” for California sales tax; that is a Texas Secretary of State form and does not apply here.
You must file a return for every period even when you had $0 in sales, since zero returns are mandatory, per CDTFA. Even if everything you sell goes to exempt distributors or resellers, you still register once and keep filing on an ongoing basis, reporting gross sales and deducting exempt or resale amounts. Riverside’s district taxes are allocated on the same CDTFA return through the Schedule A district tax allocation. One portal, one return, all rates included.
What Are the Riverside California Sales Tax Filing Deadlines?
Returns are due the last day of the month following the reporting period, per CDTFA. For a quarterly filer, the first quarter (January through March) is due April 30. CDTFA assigns your frequency from your reported or anticipated taxable sales; larger accounts also owe monthly prepayments.
| Filing frequency | How CDTFA assigns it | Due date | Source |
|---|---|---|---|
| Quarterly | Standard-volume accounts | Apr 30, Jul 31, Oct 31, Jan 31 | CDTFA |
| Quarterly with prepayments | Estimated tax liability averaging $17,000+ per month | Prepayments by the 24th of months 1 and 2; return due last day of month after the quarter | CDTFA |
| Monthly | Larger accounts CDTFA designates | Last day of the following month | CDTFA |
| Fiscal yearly or yearly | Small-volume accounts | Last day of month following the period | CDTFA |
CDTFA does not publish a single taxable-sales cutoff for every tier, so confirm your assigned frequency in your CDTFA online account. The only fixed dollar figure is the $17,000 average monthly tax liability that triggers quarterly prepayments, per CDTFA. Late or unremitted tax carries penalties and interest set by CDTFA; check your notice for the exact amount rather than assuming a flat percentage.
What Is the Riverside Transient Occupancy Tax (Lodgers Tax)?
Lodging operators in Riverside collect the city’s Transient Occupancy Tax (TOT), which is the correct name; “lodgers’ tax” is New Mexico and Colorado terminology. The City of Riverside sets its TOT at 13% of the rent charged, per the City of Riverside Finance Department. TOT is remitted to the City of Riverside, not to CDTFA.
The tax applies to hotels, motels, and short-term rentals. Riverside may also apply a Tourism Business Improvement District (TBID) assessment on qualifying lodging, so confirm both the TOT and any TBID amount with the city before you set guest pricing. TOT is entirely separate from state and district sales tax.
