Postmarks and late payment risk
Mailed property tax payments must be received or postmarked by the United States Post Office by the delinquency date to avoid penalties. If a late-arriving payment has no qualifying postmark, penalties apply under State law.
Standard postage stamps are postmarked. Metered mail, pre-canceled stamps, Automated Postal Center stamps, and permit imprints may not receive a qualifying USPS postmark. A certificate of mailing or Postage Validated Imprint label can help document the mailing date.
Electronic payments are available 24/7 and are accepted up until 11:59 p.m. Pacific Time on the delinquency date. Review the Treasurer-Tax Collector’s postmark guidance for tax payments before mailing close to a deadline.
Duplicate tax bills and public records requests
For a duplicate property tax bill, the Treasurer-Tax Collector charges a duplicate bill fee of $3.41 per bill. Requests may be made in person, through the automated system at (951) 955-3900, or by written request mailed with payment.
A duplicate bill request should include the taxpayer’s name, PIN number, fiscal year, property address, mailing address for the duplicate bill, and a phone number or email address in case the office needs help processing the request. The tax bill will be mailed within 5 business days.
Official Public Records Requests for property tax records, excluding copies of tax bills, are handled through the county’s public records request process.
Monthly and bulk payment options
Riverside County’s system cannot accept current year property taxes in more than the two regular installments. The Treasurer-Tax Collector identifies Easy Smart Pay as a third-party monthly payment option for secured property taxes, but it does not apply to supplemental property tax and is not affiliated with Riverside County.
For 15 or more parcels, the process depends on the tax type. Current secured tax bulk payments use an online payment file, but the payment itself must be submitted separately by check or wire. Supplemental, unsecured, and defaulted secured payments of 15 or more parcels require a completed Excel file submitted for review.
For wire instructions, email ttcwirepayments@rivco.org. For title company electronic payment questions, call (951) 955-1954 or email ttcwirepayments@Rivco.org.
