Look Up and Pay Solano County Property Taxes

This page helps Solano County, California property owners find tax bill information, payment options, e-billing tools, and office contacts for common property tax tasks.

The main public path is the Solano County Treasurer-Tax Collector-County Clerk Tax Search, which lets users look up property tax bills by PIN, Assessor Parcel Number, or property address.

Tax Search for property tax bills

Use the county’s online Tax Search to look up property tax bills and begin an online payment. The system supports searches by PIN, Assessor Parcel Number, or property address.

Have one of these search details ready before using the tool:

• PIN or Assessor Parcel Number from the tax bill
• Street name for a property address search
• Other account number for some personal property accounts, when applicable

For address searches, entering less information can return more results. The Street Name field requires at least three characters.

• Open the search for Solano County property taxes.
• Select either PIN or Property Address as the search type.
• Enter the required search criteria in the matching field.
• Review the bill result and continue to payment if you are ready to pay online.

Avoid street types such as LN, ST, or AVE and directions such as N, S, E, or W when a broader address search is needed.

Property tax billing and collections

The Tax Collector division handles property tax billing and collections for land, houses, boats, and businesses in Solano County. The office also provides tax bill information, tax sale information, fee schedules, assistance program information, and property tax FAQs.

The Solano County property tax system involves several county functions. The Assessor identifies taxable property and prepares the Assessment Roll. The Auditor-Controller applies the tax rate, bonds, service fees, and special assessments. The Tax Collector prints and mails property tax bills and collects tax revenues.

Online payment and e-billing options

The Tax Collector portal allows online payment by debit, credit, or e-check. Processing fees may be applied at the time of payment.

Taxpayers may also enroll in electronic billing to receive tax bills in electronic format. To subscribe, the e-billing system requires the account number or PIN from the tax bill, the access code from the tax bill, and a valid email address. One account cannot be associated with more than one email address, but one email address can be associated with more than one account.

Use the county’s electronic billing subscription service to begin or manage e-billing.

Fees and payment timing notes

Solano County lists several Tax Collector fees, with the posted fee schedule effective July 1, 2025. Fees are subject to change without notice.

For mailed payments, property tax payments must be received or postmarked by the delinquency date to avoid penalties. If a payment arrives after the delinquency date with no postmark, it is treated as late under state law.

The county notes that some postage types may not receive a USPS postmark, including metered mail, pre-canceled stamps, Automated Postal Center stamps, and permit imprint mail.

Property tax assistance and assessment questions

The Property Tax Postponement program is administered by the State Controller's Office for eligible senior, blind, or disabled homeowners who want to postpone current-year property taxes on a primary residence. Applications are accepted from October 1 to February 10 each year.

For possible property tax savings, the county directs taxpayers to contact the Solano County Assessor about exemptions such as the Homeowner's Exemption, 100 percent Disabled Veteran's Exemption, or Church and Welfare Exemption.

Tax sale information

The Solano County Treasurer - Tax Collector - County Clerk conducts sales of tax defaulted properties at least once every four years under California Revenue and Taxation Code §3691 and at the direction of the Solano County Board of Supervisors.

The county states that tax sales are generally held in May or June through an online tax auction service. The Solano County tax sale reoffer is scheduled for June 17–18, 2026.

Potential bidders should review tax sale rules, inspect properties of interest, and understand that a tax deed may not clear all recorded encumbrances, including special assessments, income tax liens, mechanics liens, street bonds, and other taxing agency obligations.
