Search, Pay or Fix a Solano County Tax Bill
Use the official Tax Collector portal for tax bills, balances and payment. Use the Assessor property search for parcel, value and property information. The two systems answer different questions and should not be treated as interchangeable records.
This guide explains the PIN and address search, office phone and hours, mailing and postmark rules, secured and supplemental bills, payment proof, appeals, assistance programs and delinquent-account next steps.

What are you trying to find?
Use the Tax Collector portal for bills, installments, balances, payment options, e-billing and receipts.
Use the Assessor search for APN, assessment, property characteristics, exemptions and mailing-address help.
Use the Recorder’s official-records index. An Assessor page or tax bill is not the recorded legal document.
How to look up and pay Solano County property tax online
Use the PIN, address or personal-property account correctly
| Search route | What to enter | Best practice | Common failure |
|---|---|---|---|
| PIN / Assessor Parcel Number | The 10-digit number shown on the tax bill. | Copy all digits and compare the resulting property before opening a bill. | Using a mortgage loan number, tax-rate-area number or a shortened parcel reference. |
| Property address | At least three street-name characters; add the street number only when useful. | Start with less information and omit suffixes and directions. | Entering LN, ST, AVE, N, S, E or W when the database stores the address differently. |
| Personal-property account | The 13-character account number when supplied on the bill; it may contain letters and numbers. | Copy the exact account from the current notice. | Treating it as the 10-digit real-property PIN. |
No result found?
Tax lookup, Assessor property search or Recorder records?
| System | What it shows | Use it for | Important limitation |
|---|---|---|---|
| Tax Collector Tax Search | Tax bills, installments, balances and payment routes. | Paying, checking a bill, reviewing installment status or finding an account. | It does not decide value, exemptions or legal ownership. |
| Assessor Property Search | Parcel, assessment and available property information. | Finding the APN, value, assessment context and property details. | The county warns that data may contain errors, omissions or outdated information; it is not a payoff. |
| Recorder Official Records Search | Indexed deeds, liens, easements, maps and other recorded documents. | Legal-document research and recording history. | The online index may not display document images and is not a tax-balance screen. |
| Assessment Appeals | Application, deadlines and hearing process for valuation disputes. | Formal challenge when evidence supports a lower or corrected assessment. | Filing an appeal is not the same as paying or stopping collection. |
Online payment methods and fee checks
Available through the official portal. Enter routing and account information carefully and review the final fee before authorization.
Accepted electronically. The portal warns that a processing fee may apply and shows the charge during the payment flow.
The county links a 2026/27 Tax Collector fee schedule effective July 1, 2026. Fee schedules are subject to change without notice.

Write the PIN or parcel number in the lower-left corner of the check.
Counter hours are Monday–Friday, 8:30 a.m.–4:00 p.m. The county also states that a drop box is available.
Confirm drop-box placement and access before relying on after-hours delivery.
Avoid a late penalty when mailing the payment
Solano County says a property-tax payment must be received or postmarked by the delinquency date. Mail received late without a qualifying postmark is treated as late under state law.
| Mail method | Risk | Safer action |
|---|---|---|
| Ordinary stamp | Usually postmarked, but processing can occur after the drop-off date. | Mail early or ask for a manual postmark at the counter. |
| Metered mail or Stamps.com | May not receive a qualifying USPS postmark. | Use a retail-counter service that produces acceptance proof. |
| Automated Postal Center stamp | A printed date may not establish the required postmark. | Request a Postage Validation Imprint from a postal employee. |
| Bank bill-pay check | The bank may mail a paper check using a permit imprint without a normal postmark. | Schedule well before the deadline and verify when the county received it. |
| Certified, registered or Certificate of Mailing | Additional cost. | Retain the receipt as evidence of the presentation date. |

Due dates, delinquency dates and current status
Secured, supplemental, unsecured and prior-year bills
| Bill type | Usually relates to | What to verify | Common mistake |
|---|---|---|---|
| Annual secured | Land and improvements secured by real property. | Fiscal year, PIN and first/second installment. | Assuming it includes a separate supplemental bill. |
| Supplemental | Change in ownership or completed new construction. | Separate bill dates, assessment period and whether one or two supplemental bills exist. | Assuming the mortgage servicer automatically pays it. |
| Unsecured | Business personal property, boats, aircraft and other property not secured by land. | Account number and the due/delinquent date printed on that bill. | Applying the annual secured two-installment calendar. |
| Prior-year delinquent / redemption | Older secured taxes that have become tax-defaulted. | Current redemption payoff, fees and whether an installment plan may be available. | Paying only the current-year annual bill. |
| Direct levy or special assessment | Charge placed on the bill by a city, district or other agency. | Originating agency, description and contact on the bill. | Expecting the Tax Collector to explain or remove another agency’s levy. |
What to do when the bill did not arrive
Confirm the tax payment was applied to the correct account
| Route | Keep | Recheck |
|---|---|---|
| Online | Digital receipt, confirmation email and bank/card record. | PIN, fiscal year, bill type, installment and paid status. |
| Check image, stub copy and postmark or mailing proof. | County receipt date and the account on which the check posted. | |
| Counter | Dated county receipt. | The receipt lists the intended PIN and installment. |
| Drop box | Check/stub copies and date/time notes. | Posting after county processing; a drop-off is not an immediate receipt. |
| Mortgage servicer | Escrow statement, check/reference number, amount and disbursement date. | The county account rather than only the lender’s “sent” status. |
Tax Collector, Assessor, Auditor, Recorder or Appeals?
| Your question | Correct office | Why |
|---|---|---|
| How much do I owe, did I pay or why is there a penalty? | Tax Collector | Prints bills and handles collection, posting, delinquency and redemption. |
| What is the APN, assessed value or property description? | Assessor | Identifies taxable property, establishes value, applies exemptions and produces parcel maps. |
| Why does the bill contain a tax rate or direct levy? | Auditor-Controller or originating agency | Extends the roll, calculates rates/charges and allocates revenue. |
| Where is the recorded deed, lien or easement? | Recorder | Maintains official recorded real-property documents. |
| How do I challenge the assessed value formally? | Clerk of the Board / Assessment Appeals Board | Processes and decides formal assessment disputes. |

Assessment review and formal appeal deadlines
The Assessor makes the decline-in-value review route available July 1–November 30 for the most recent January 1 assessment. It does not review prior years or supplemental assessments.
The regular filing period is July 2–November 30. A $35 nonrefundable fee applies per parcel, and the taxpayer should have evidence that the assessment is inaccurate.
| Assessment type | Filing deadline | Evidence focus |
|---|---|---|
| Regular annual assessment | July 2–November 30, extended to the next business day when November 30 is a weekend or legal holiday. | Value as of January 1 of the current year. |
| Supplemental assessment | Within 60 days after the printed mailing date or postmark date, whichever is later. | Whether the reassessment event or supplemental value is incorrect. |
| Escape, roll-change or penalty assessment | Within 60 days after the notice mailing date or postmark, whichever is later. | Why the enrollment, year or value is incorrect; one application may be needed for each year. |

Property-tax postponement and Assessor exemptions
The State Controller administers a program that may allow an eligible senior, blind or disabled homeowner to postpone current-year taxes on a principal residence.
Applications are accepted October 1–February 10 each year.
State help: 800-952-5661
Ask the Assessor about programs such as the Homeowner’s Exemption, 100% Disabled Veteran’s Exemption, nonprofit exemptions, family-transfer exclusions and temporary decline-in-value review.
An exemption or postponement requires eligibility and an application; do not deduct an amount from the bill yourself.

Solano County Tax Collector FAQs
How do I pay Solano County property tax online?
Use the official Solano County Public Access Tax Collector portal. Search by the 10-digit PIN or Assessor Parcel Number shown on the tax bill, or by property address. Open the correct tax account and bill, verify the fiscal year and installment, review any processing fee, submit the payment and save the emailed digital receipt.
What is the Solano County Tax Collector phone number?
Call 707-784-7485 for property-tax bills, payments, copies, delinquent accounts, redemption and tax-sale questions. Published telephone hours are Monday–Friday, 10:00 a.m.–noon and 1:00–3:00 p.m.
What is the official Solano County Tax Collector website?
The official information page is on SolanoCounty.gov. The county-authorized Public Access portal at ca-solano.publicaccessnow.com provides property-tax search, payment, e-billing and electronic forms.
How do I look up a Solano County property-tax bill?
Open the official Tax Search page and choose PIN or Property Address. The PIN is a 10-digit number on the tax bill. For an address search, enter at least three street-name characters, use less information first and omit street types and directions.
What is the difference between tax lookup and property search?
The Tax Collector lookup shows tax bills, installments, balances and payment options. The Assessor property search shows parcel, value and assessment information. The Recorder index is used for deeds, liens, easements and recorded documents. An Assessor record is not a tax payoff or legal-title guarantee.
Where is the Tax Collector office and what are its hours?
The office is at 675 Texas Street, Suite 1900, Fairfield, CA 94533. Published counter hours are Monday–Friday, 8:30 a.m.–4:00 p.m., excluding county holidays.
What is the Solano County property-tax mailing address?
When using the bill stub and return envelope, mail payment to Solano County Tax Collector, PO Box 51094, Los Angeles, CA 90051-5394. Without the stub, the dated county notice directs payment to 675 Texas Street, Suite 1900, Fairfield, CA 94533 with the PIN or parcel number written on the check.
When are secured property taxes due?
The standard California schedule makes the first installment due November 1 and delinquent after December 10, and the second due February 1 and delinquent after April 10, subject to weekend and holiday rules. The 2025/26 Solano dates have passed as of August 4, 2026.
What should a new owner do if no tax bill arrived?
Search the official portal by PIN or property address and contact the Tax Collector for a copy and complete balance. Failure to receive a bill does not excuse payment or penalties. Ask the mortgage servicer whether annual and supplemental bills are covered rather than assuming every bill is paid through escrow.
Should I contact the Tax Collector or Assessor?
Use the Tax Collector for bills, balances, payments, receipts, penalties, delinquent taxes and redemption. Use the Assessor for parcel identification, value, exemptions, property characteristics and mailing-address changes. Formal assessment appeals go to the Clerk of the Board and Assessment Appeals Board.
