If you’re buying or selling a home in Palm Springs or anywhere in the Coachella Valley, understanding property taxes is an important part of the process. Since this area falls under the jurisdiction of Riverside County, California, property tax rules are governed at the county level.

This blog post is intended to give you a basic overview of property taxes and special assessments on homes. It is provided for informational purposes only and is not tax or legal advice. Please consult your tax advisor and legal counsel for guidance on your specific situation.

How Property Taxes Are Calculated in Riverside County

Property taxes in Riverside County are typically capped at approximately 1.25% of the assessed value, plus any supplemental taxes, assessments, Melo Roos and fees.

When you purchase a home, the property is reassessed at the time of sale based on the market value—usually the price you paid. The total amount of property taxes you’ll owe depends on:

• Purchase price and assessed value

• Property type and size

• Whether it’s your primary residence, second home, or investment property

• Personal circumstances, such as age bracket or veteran status

Supplemental Taxes

Under California law, property is reappraised when ownership changes or when new construction is completed.

• Your regular tax bill is based on the assessed value as of January 1.

• A supplemental tax bill is issued if the new assessed value is higher than the previous one. This bill is separate from your regular tax bill and comes directly from the Riverside County Treasurer-Tax Collector.

The county offers a Supplemental Tax Estimator to help you estimate what you might owe after buying a home. Keep in mind this tool applies only to ownership changes, not new construction.

Special Assessments and Fees

Property tax bills often include extra assessments that help fund vital public services such as:

• Schools and libraries

• Police and fire departments

• Parks and recreation

• Sewage, drainage, and street maintenance

Proposition 13

This statewide property tax provides funding for California’s public education system.

Mello-Roos Districts (Community Facilities Districts)

Created by municipalities at the request of developers, these districts fund specific public improvements like schools, parks, and libraries. Mello-Roos taxes can vary widely depending on the scope of the project and are often found in newer subdivisions.

Special Assessment Districts (Public Works Bonds)

These finance improvements that benefit certain properties, such as roads, water distribution, sewer systems, and utilities. Unlike Mello-Roos, they are tied to direct property benefits.

The County Assessor does not control the placement or amounts of these assessments. For details, visit the Riverside County Assessor’s Office website.

Payment Schedule

Property taxes in California are billed annually and split into two installments:

• First installment: Due by December 10

• Second installment: Due by April 10

Bills are mailed in late September or early October. You can pay online via the Riverside County Tax Portal or by using the county’s automated phone-pay system (note: convenience fees may apply).
