A CPA firm for Riverside, CA businesses
Scalesight CPA's Riverside office gives Inland Empire owners a local address and a local 951 phone number for the same CPA-led team that handles our clients' tax, books and CFO work everywhere else. Business tax preparation is the core, and it is backed by year-round planning, a monthly close and fractional CFO reporting. See the full list on our services page.
Riverside had 314,998 residents at the 2020 Census, and Riverside County had 2,418,185. We set up the Riverside office for owners of logistics and distribution companies, contractors and trades, and manufacturers. It also fits medical and dental practices, restaurant groups, professional services firms and companies that have outgrown a once-a-year preparer.
California stacks several costs on a growing company: the $800 minimum tax, an LLC fee based on revenue and a City of Riverside business tax. Sales tax rates can change from one city to the next, and the state does not automatically follow new federal tax law. Getting those right is where a CPA earns the fee.
What Riverside companies ask us for
- Catch-up bookkeeping and a monthly close before the next California deadline
- LLC versus S corporation reviews that weigh the $800 tax, the LLC fee and the 1.5 percent rate
- PTE elective tax modeling and the June 15 payment for S corporations and partnerships
- Sales and use tax reviews for deliveries into cities with different rates, and for ready-made software taxed starting January 1, 2027
- City business tax certificate and Statement of Information calendars so nothing lapses
- EDD payroll registration and filings as the team grows
- Fractional CFO forecasting for hiring, a new location or warehouse, financing or a sale

California tax rules Riverside owners run into
The $800 minimum tax
Corporations and LLCs registered or doing business in California generally owe at least $800 a year, even with a loss. For 2026, most C corporations pay 8.84 percent of California net income and S corporations 1.5 percent, with $800 as the floor. New corporations skip the $800 in year one. A new LLC whose first tax year starts in 2027-2029 pays $400 that year.
The LLC fee follows revenue
LLCs with $250,000 or more of total California income also owe a fee, and total income works like gross receipts, not profit. For 2026 the fee starts at $900 and rises to $2,500 at $500,000, $6,000 at $1 million and $11,790 at $5 million or more. Estimate and pay it on Form FTB 3536 by June 15 for a calendar-year LLC.
PTE elective tax through 2030
Most S corporations and partnerships can elect to pay 9.3 percent of qualified net income at the entity level through 2030, which can help owners whose federal deduction for state taxes is capped. The first payment is due June 15. Starting in 2026, missing it no longer blocks the election, but it cuts the owners' credit by 12.5 percent of the unpaid amount.
Sales tax in the City of Riverside
Most taxable sales in the city are taxed at 8.75 percent (CDTFA table effective October 1, 2026): 7.25 percent statewide, 0.50 percent for the county transportation commission and 1 percent for the city's Measure Z tax. Rates change at city lines: Jurupa Valley is 7.75 percent and Palm Springs 9.25 percent. Starting January 1, 2027, most ready-made software, including software used online, becomes taxable.
City business tax certificate
Anyone doing business in Riverside needs a city business tax certificate before opening. That includes home businesses and companies that work in the city from an office elsewhere. Each activity at each location needs its own certificate. New businesses that pay late owe a 30 percent penalty after 60 days, rising to 75 percent at 120 days.
Statement of Information
Stock corporations file a Statement of Information with the Secretary of State every year ($25) and LLCs every two years ($20), in the six months ending with the month the entity was formed or registered. Since August 1, 2026, online filing requires User Access in bizfile Online. A missed filing can bring a $250 penalty.
Rates and thresholds change. We confirm the current rules for your business before filing.

What is the sales tax rate in Riverside, California?
Most taxable sales in the City of Riverside are taxed at 8.75 percent under CDTFA's October 1, 2026 rate table: 7.25 percent statewide, 0.50 percent for the county transportation commission and 1 percent for the city's Measure Z tax, which is set to end in 2036. Voters rejected a June 2026 measure to raise Measure Z to 1.25 percent.
Does my California LLC owe both the $800 tax and the LLC fee?
Yes, once its total California income reaches $250,000. The $800 annual tax is due by April 15 for a calendar-year LLC, even if it is not doing business, and the fee of $900 to $11,790 comes on top. A new LLC whose first tax year starts in 2027-2029 pays $400 instead of $800 that year.
Do I need a City of Riverside business tax certificate?
Yes, if you do business in the city, even from a home office or an office elsewhere. For November 1, 2026 to October 31, 2027, a general services firm pays a $190.25 base plus $6 per added employee or owner. A professional services firm pays $291.25 plus $292 per added professional and $6 per other employee. A $4 state fee is added.
What payroll taxes do California employers pay?
Employers register with the EDD. New employers pay 3.4 percent for unemployment insurance, and most also pay the 0.1 percent Employment Training Tax for 2026 and 2027, both on each worker's first $7,000 of wages a year. They also withhold State Disability Insurance: 1.3 percent for 2026 and 1.4 percent for 2027, with no wage cap.

Yes. The Riverside number reaches the same team that serves clients in all 50 states. California owners with operations in Arizona, Nevada or other states get multi-state filings from one firm.
