Solano County property tax rate by city, 2026-27
Every Solano County parcel pays the 1.000000% general levy and a 0.020000% Solano County Water Agency levy for State Water Project costs. The rest comes from community college bonds (Solano Community College, or San Joaquin Delta College in the Rio Vista area), the local school district's bonds and, in a few cities, a small city debt rate. The Auditor-Controller publishes a general tax rate for each city's main tax rate area, shown here with last year's rate and Zillow's typical home value for September 2026.
| City (main TRA) | 2025-26 total rate | 2026-27 total rate | Zillow typical value, Sept 2026 | Tax on typical value at 2026-27 rate* |
|---|---|---|---|---|
| Benicia (1000) | 1.156944% | 1.134905% | $780,445 | $8,778 |
| Dixon (2000) | 1.096147% | 1.107488% | $605,822 | $6,632 |
| Fairfield (3000) | 1.110049% | 1.121057% | $598,419 | $6,630 |
| Rio Vista (4000) | 1.069800% | 1.079695% | $451,283 | $4,797 |
| Suisun City (5000) | 1.110315% | 1.121587% | $530,234 | $5,869 |
| Vacaville (6000) | 1.144337% | 1.153190% | $600,979 | $6,850 |
| Vallejo (7000) | 1.119373% | 1.119188% | $517,277 | $5,711 |
*Typical value less the $7,000 homeowners' exemption, times the 2026-27 rate. Special taxes and fixed charges are extra.
Why Benicia's rate fell while most others rose
Benicia Unified's 1997 bond, which added 0.047149% in 2025-26, drops to zero for 2026-27, so Benicia's total fell by about 0.022 points. Most other cities rose by about 0.01 points as school bond payments grew. Vallejo was nearly flat, and it carries no city debt rate this year.
Rio Vista and the Delta areas
Rio Vista has the lowest city rate even though it includes a River Delta flood district levy of 0.050495%, because its schools sit in River Delta Unified and San Joaquin Delta College rather than the Solano college district.
Rates by tax rate area: unincorporated Solano and Vallejo's landscape districts
The county's 2026-27 TRA fund composition report runs to 1,035 pages, because each combination of school, fire, water and special district gets its own tax rate area. These are the most common rates in the unincorporated groups. The area labels come from the school and fire districts in each group, so confirm your own TRA on the bill.
| Unincorporated TRA group | School and fire districts | 2026-27 total rate |
|---|---|---|
| 052xxx | Benicia USD, Cordelia Fire | 1.134905% |
| 060xxx | Fairfield-Suisun USD, Cordelia Fire | 1.119457% |
| 062000 | Davis Joint USD | 1.089161% |
| 063xxx | Dixon USD, Dixon Fire | 1.107488% |
| 077xxx | Winters Joint USD | 1.186707% |
| 084xxx | River Delta USD, Montezuma Fire | 1.059695% |
| 089xxx | Travis USD | 1.093642% |
| 091xxx | Vacaville USD, Vaca-Elmira Fire | 1.102920% |
Vallejo TRAs that add a landscape maintenance district
Vallejo is unusual: several of its landscape maintenance districts are collected as an ad valorem rate on top of the city's 1.119188%. That pushes the total well above anything else in the county.
| Vallejo TRA | District | District rate | 2026-27 total rate |
|---|---|---|---|
| 007043 | Costa del Rio | 0.287% | 1.406188% |
| 007032 | Springtree | 0.195% | 1.314188% |
| 007031 | Glen Cove | 0.190% | 1.309188% |
| 007001 | Monica Place Road | 0.187% | 1.306188% |
| 007042 | Town and Country | 0.150% | 1.269188% |
| 007033 | Ridgecrest | 0.115% | 1.234188% |
| 007026 | College Hills | 0.100% | 1.219188% |
Who to ask about a Solano County rate
The Auditor-Controller's property tax unit answers rate questions at (707) 784-6283 or prop@solanocounty.gov. On a $564,152 net value, the Costa del Rio TRA costs about $7,933 a year against $6,314 in Vallejo's base TRA, a difference of about $1,619.
Worked example: a Solano County bill under Prop 13
Prop 13 fixes your assessed value at the price you pay, then caps increases at 2% a year. This example uses Zillow's September 2026 typical Solano County value of $571,152 for an owner-occupied home in Fairfield's main TRA 3000.
| Line | Amount |
|---|---|
| Purchase price = assessed value | $571,152 |
| Less homeowners' exemption | -$7,000 |
| Net taxable value | $564,152 |
| 1% general levy | $5,641.52 |
| Water agency, college, school and city debt (0.121057%) | $682.95 |
| Ad valorem tax at 1.121057% | $6,324.47 |
| Mello-Roos, landscape and sewer charges | Depends on the parcel |
Year two on the same Fairfield home
With the full 2% factor the assessed value becomes $582,575. After the exemption, at the same rate, the ad valorem tax would be about $6,453. The debt rate changes each October, so treat this as an estimate.
The same price elsewhere in Solano County
On the same $564,152 net value, 2026-27 ad valorem tax is about $6,506 in Vacaville, $6,403 in Benicia, $6,327 in Suisun City, $6,314 in Vallejo, $6,248 in Dixon and $6,091 in Rio Vista. The ad valorem spread between cities is about $415 a year; a Mello-Roos district on a newer home can add more than that on its own. The California property tax guide covers the statewide rules.
Solano County property tax exemptions
Homeowners' exemption in Solano County
If you own and live in the home as your main residence on January 1, the $7,000 homeowners' exemption saves about $78 a year at Fairfield's rate. File form BOE-266 with the Solano County Assessor (exemptions@solanocounty.gov). A claim filed by February 15 gets the full exemption; one filed between February 16 and December 10 gets a partial one. New buyers who move in within 90 days of buying can also have it applied to the supplemental assessment.
Disabled veterans' exemption in Solano County
Veterans with a 100% service-connected rating or individual unemployability, blindness in both eyes or loss of use of two or more limbs, and qualifying unmarried surviving spouses can file form BOE-261-G with a DD-214 and the VA rating letter. The Assessor mails a BOE-261-GNT eligibility report each year. The state sets the amounts: for the 2026 lien date, the Board of Equalization lists $180,671 of assessed value for the basic exemption and $271,009 for the low-income exemption, with a household income limit of $81,131. For 2027 the figures are $185,889, $278,836 and $83,474.
Prop 19 base-year transfers in Solano County
Solano County homeowners who are 55 or older, severely disabled, or victims of a wildfire or disaster can carry their Prop 13 value to a replacement home anywhere in California up to three times (once for disaster victims), and parent-child transfers now apply only to a family home the child moves into. Our Prop 19 guide has the full rules.
Solano County Prop 19 forms
- BOE-19-B: base-year transfer for owners 55 and older.
- BOE-19-D: base-year transfer for severely disabled owners.
- BOE-19-V: base-year transfer for disaster victims.
- BOE-19-P and BOE-19-G: parent-child and grandparent-grandchild transfers.
Questions go to the Assessor at (707) 784-6210, 675 Texas Street, Suite 2700, Fairfield.
Calamity relief in Solano County
If fire, flood or another disaster causes more than $10,000 of damage, file the Assessor's calamity claim within 12 months to have the value lowered until the home is repaired.
Supplemental bills after buying in Solano County
The Solano County Tax Collector explains that a change of ownership or new construction triggers a supplemental bill on the difference between the old and new values. A change between July and December produces one supplemental bill; a change between January and June produces two. Supplemental bills are due when you receive them and go delinquent on the dates printed on the bill, with a 10% penalty plus $20 on the second installment. Mortgage impound accounts usually do not pay them.
Solano County supplemental bill example
Say the seller's taxable value was $300,000 and you close on the Fairfield home above for $571,152 on January 1, 2027. The supplemental value is $271,152. With half of the 2026-27 fiscal year left, the first bill at 1.121057% is about $271,152 x 1.121057% x 0.5 = $1,520. The second covers 2027-28, about $3,040 before rate changes. Set this money aside at closing.
Mello-Roos and special taxes on Solano County bills
Solano County's newer subdivisions rely heavily on community facilities districts (CFDs). The Auditor-Controller's 2026-27 special assessment contact list names these districts, among others. Amounts vary by parcel, so ask for the seller's last bill and the CFD's rate and maturity. Our Mello-Roos guide explains how they work.
Fairfield and Suisun City CFDs
Fairfield lists CFD 2016-1, CFD 2019-1 and CFD 2023-1 for One Lake, CFD 2018-1 and CFD 2023-2 for the Train Station area, and CFD 2006-1 for public safety and park maintenance. Suisun City has a citywide CFD No. 2 and CFD No. 5. Travis Unified also runs Mello-Roos districts No. 1 and No. 2.
Vacaville, Dixon, Vallejo and Rio Vista CFDs
Vacaville lists CFDs No. 8 through No. 12 and CFD No. 13 for Lower Lagoon Valley. Dixon has CFD 2019-1 (Homestead), CFD 2013-1 (Parklane) and the citywide services CFD 2024-1. Vallejo's Mare Island has CFDs 2002-1 and 2005-1A. Rio Vista lists CFD 2006-1 and CFD 2018-1, and River Delta Unified and Davis Joint Unified each have a CFD.
Parcel taxes and service charges
Other common lines include Cordelia Fire Measure I, the Greater Vallejo Recreation District, the San Francisco Bay Restoration Authority's Measure AA, Davis Joint Unified Measures G and N, landscape and lighting districts in Dixon, Fairfield, Vacaville, Vallejo and Suisun City, Vallejo Flood and Wastewater and Fairfield-Suisun sewer charges, the Solano Subbasin groundwater agency charge, and PACE loans.
Paying Solano County property tax: due dates and fees
Solano County mails secured bills by November 1. The first installment is due November 1 and becomes delinquent after 5 p.m. on December 10, with a 10% penalty. The second is due February 1 and becomes delinquent after 5 p.m. on April 10, with a 10% penalty plus a $20 cost. If a delinquent date falls on a weekend or holiday, it moves to the next business day, so the 2026-27 second installment deadline is Monday, April 12, 2027.

Appealing a Solano County assessment
Informal Prop 8 review with the Solano County Assessor
If your home was worth less than its assessed value on January 1, ask the Assessor for a decline-in-value (Prop 8) review on the 2026-27 request form. The Assessor's page gives a July 1 to November 30 window and says sales through March 31 can be used. There is no fee.
Formal appeal to the Solano County Assessment Appeals Board
The Clerk of the Board runs the Assessment Appeals Board. Regular applications are accepted July 2 to November 30, and the fee is $35 per parcel, non-refundable. Supplemental and escape assessments must be appealed within 60 days of the notice. The Clerk says hearings take about 10 to 12 months to schedule and the board has up to two years to decide, so keep paying your bill while you wait. Contact clerk@solanocounty.gov or (707) 784-6100. The county's 2026-27 roll grew about 3.4% to roughly $80.6 billion, with about 1,300 prior-year appeals still pending, according to local reporting.
