Simi Valley Property Tax: 2026 Rates, Calculator, Exemptions

Simi Valley Property Tax for 2026 means a base 1 % rate set by Proposition 13 plus local voter‑approved levies that typically push the effective rate to about 1.16 % of assessed value, though special assessments in newer districts can add another 0.1‑0.4 %. Homeowners can estimate their liability with a property tax calculator for Simi Valley homes, entering the latest Simi Valley home value assessment and any applicable parcel tax amounts, Mello‑Roos fees, or condo assessments; the result shows the 2026 property tax bill Simi Valley residents will receive each December.

Simi Valley Property Tax Rates and How They Build Up

Simi Valley City property tax rates start with the 1% base set by Proposition 13. Local voter-approved bonds and special district fees stack on top. The total effective rate for most homes lands around 1.16% of assessed value. Rates shift by tax rate area based on the school district, water district, and Community Facilities District that cover each parcel.

Newer neighborhoods like Big Sky and parts of Sycamore Grove carry Mello-Roos fees. These fees can add $1,800 to $4,500 per year on top of the percentage rate. Check the tax rate area code on your parcel record to see which districts apply to your home.

Simi Valley Tax Assessment and the Assessor Role

The Ventura County Assessor sets the assessed value of every property in Simi Valley each year. Values are set on the lien date of January 1 and capped at a 2% annual increase under Proposition 13. The cap stays in place until the property changes ownership or new construction happens.

• The Assessor certifies the annual roll by July 1 each year.
• Value notices are mailed before August 1 to every property owner.
• New construction, room additions, and pool builds trigger a supplemental assessment.
• A change of ownership resets the assessed value to the sale price.
• Decline-in-value requests can lower the assessment when the market drops below the Prop 13 value.

Look up the assessment roll on the Assessor portal at assessor.venturacounty.gov. Call (805) 654-2181 with questions about a specific parcel or value notice.

Simi Valley Property Tax Calculator Steps

You can estimate your Simi Valley City property tax bill with a simple formula. Multiplying the assessed value by the local tax rate gives a close result for most homes. The Assessor parcel page holds both numbers you need for the math.

1. Pull the assessed value from the Assessor parcel search page.
2. Find the tax rate area code on the same parcel record.
3. Match the code to a combined rate, which sits near 1.16% for most Simi Valley homes.
4. Multiply the assessed value by the rate. A $700,000 home at 1.16% equals $8,120 per year.
5. Add any flat-dollar Mello-Roos fees shown in the special district section.
6. Divide the total by 12 to see the monthly escrow amount your lender may collect.

Online third-party tools can run the math fast. The most accurate number always comes from the official bill mailed by the Treasurer-Tax Collector each fall.

Reading the Simi Valley Property Tax Bill

A Simi Valley property tax bill lists the parcel, the assessed value, the tax rate area, the base 1% charge, voter-approved bond charges, and any special assessments. Each line shows a rate, a dollar amount, and the agency that receives the funds. The bill also shows the two installment dates and any penalties from a prior bill.

• Parcel Number: The APN that ties the bill to the property.
• Assessed Value: The Proposition 13 value as of January 1 of the tax year.
• Base 1% Levy: The main tax that funds schools, cities, and special districts.
• Voter-Approved Debt: Local bonds approved by voters for schools or infrastructure.
• Special Assessments: Mello-Roos fees, water stand-by charges, or lighting districts.
• Total Amount Due: The sum of all charges for the installment period.

Pay close attention to the installment dates printed near the bottom of the bill. Missing the first installment triggers penalties even if the second installment lands on time.

Simi Valley Property Tax Payment and Appeal Deadlines

Secured property tax bills in Ventura County run on a fiscal year that starts July 1. Bills are mailed once a year in October, then split into two equal installments for payment. The appeal period for the assessed value runs from July 2 to November 30 each year.

• Pay online through the Treasurer-Tax Collector portal using an eCheck or credit card.
• Mail a check with the stub from the bill to the Ventura County Hall of Administration.
• Pay in person at 800 S. Victoria Ave., Ventura, CA 93009. The office is open Monday–Friday, 8:00 AM–5:00 PM (cash transactions until 4:30 PM).
• Set up a monthly escrow with your mortgage servicer to avoid missed deadlines.

Supplemental bills have their own due dates printed on the front page. Read every line of the bill to avoid surprise charges.

Simi Valley Property Tax Exemptions for Seniors

California offers property tax relief to seniors through several programs. The first is the standard Homeowners’ Exemption, which provides a reduction in assessed value for owner-occupied homes. The second is the property tax postponement program, which lets qualifying seniors delay payment until the home is sold.

• File the Homeowners’ Exemption claim once with the Ventura County Assessor.
• Apply for the postponement program through the State Controller’s Office.
• Submit income and age documents each year the postponement stays active.
• Reapply for the senior cash assistance every year by the deadline.
• Check the Homeowners’ Exemption status on the Assessor portal at assessor.venturacounty.gov.

Each program has its own deadline and paperwork. Call (805) 654-2181 to ask which forms apply to your situation before you visit the office.

Simi Valley Property Tax Exemption for Veterans

Veterans with a service-connected disability rating from the VA may qualify for a property tax exemption in California. The exemption amount depends on the disability rating and the wartime or peacetime status of the veteran. The exemption runs on the assessed value of the home, not on the market price.

• Basic exemption: A reduction off the assessed value for honorably discharged veterans.
• Disabled veteran exemption: A reduction off the assessed value, scaled by disability rating.
• Unmarried surviving spouse: May claim the same exemption as the deceased veteran.
• Documentation: Submit DD-214, VA disability letter, and proof of ownership to the Assessor.
• Annual renewal: Some disabled veteran exemptions need yearly proof of VA status.

Apply at the Ventura County Assessor’s Office at 800 S. Victoria Ave., Ventura, CA 93009. Email assessor.info@ventura.org for the correct form packet before visiting in person.

How to Appeal a Simi Valley Property Assessment

Property owners in Ventura County can file a formal appeal when they believe the assessed value is too high. The regular appeal window opens on July 2 and closes on November 30 each year for the current tax year’s value. Appeals are filed with the Ventura County Assessment Appeals Board, a body separate from the Assessor’s office.

1. Pull comparable sales from January 1 of the tax year that support a lower value.
2. Take photos of any condition issues, such as foundation cracks, water damage, or roof wear.
3. Fill out the application for changed assessment from the Assessment Appeals Board.
4. Pay the filing fee, which depends on the property type and assessed value.
5. Mail or deliver the packet to the Clerk of the Assessment Appeals Board.
6. Attend the hearing date set by the Board and present your evidence in person.

An informal review with the Assessor often settles the issue before a formal hearing. Phone (805) 654-2181 to start that conversation and ask about a Prop 8 decline-in-value review.

Simi Valley Property Tax Delinquency and Penalties

A property tax bill becomes delinquent if the Treasurer-Tax Collector does not receive payment by 5:00 PM on the due date. Penalties add up fast and grow the longer the bill stays unpaid. The Treasurer-Tax Collector charges a flat penalty plus a daily cost on the unpaid balance.

• First installment late: A late payment penalty plus a flat collection cost.
• Second installment late: A late payment penalty plus a flat collection cost.
• Bills unpaid at year-end: A redemption fee and a daily cost on the redemption plan.
• Extended default: The property may be sold at a public auction to recover the debt.
• Lien: A delinquent bill becomes a lien that stays on the property until paid in full.

Act fast if you receive a late notice. Even partial payments can stop the auction process in some cases. Call the Treasurer-Tax Collector office to ask about a redemption plan before the auction date.

Simi Valley Property Tax Lien and Sale Process

An unpaid property tax bill becomes a lien on the property. The lien stays attached until the bill, penalties, and costs are paid in full. The lien stays on the title even if the property is sold or refinanced during the default period.

• Default date: A bill is in default if the second installment stays unpaid by the end of the fiscal year.
• Notice of sale: A recorded notice lists the parcel and the amount due before the auction.
• Auction: The Treasurer-Tax Collector runs a public sale of the tax-defaulted property.
• Redemption window: The owner can pay the full debt plus costs to stop the sale and reclaim the title.
• Deed transfer: If the owner does not redeem, the winning bidder receives a tax deed to the property.

Check the Treasurer-Tax Collector public auction list each spring to see if a Simi Valley parcel is at risk. The list is published in a local newspaper and posted at the Ventura County Hall of Administration.

California Property Tax Deferral Options for Simi Valley Owners

California runs two main deferral programs for property owners who cannot pay their bills. Both programs place a lien on the property and must be repaid when the home is sold, transferred, or no longer used as a primary residence. The deferral covers the current-year tax and any penalties tied to the late payment.

• Senior Property Tax Deferral: For homeowners age 62 or older with limited income.
• Disability Property Tax Deferral: For homeowners with a qualifying permanent disability.
• Income limits: Set each year by the State Controller’s Office.
• Repayment: The State collects the deferred amount when the property changes hands.

Apply directly through the State Controller’s Office website. Approval processing times vary, so file before the December 10 due date to avoid penalties on the current-year bill.

Simi Valley Special Assessments and Mello-Roos Fees

Some Simi Valley neighborhoods sit inside Community Facilities Districts (CFDs) created under the Mello-Roos Act. These districts add a special tax to fund new roads, schools, parks, and storm drains in newer developments. The fee appears as a separate line on the tax bill, below the base 1% charge and the voter-approved debt.

• Big Sky: A CFD that adds a flat annual fee to each parcel for road and park upkeep.
• Sycamore Grove: A CFD that funds shared open space and school facilities.
• Other newer tracts: Check the parcel record to see if a CFD fee applies.
• Sunset years: Most CFDs have a sunset date printed on the original formation document.
• Disclosure: Sellers must disclose active CFD fees to buyers before close of escrow.

Mello-Roos fees stay on the bill until the bonds are paid off or the district expires. Read the CFD section of the tax bill to see the exact annual amount and the agency that receives the funds.

Simi Valley Property Tax on Condominiums

Condos in Simi Valley City are assessed the same way as single-family homes, but the Homeowners’ Association (HOA) dues are separate from the property tax bill. Each condo unit has its own APN and its own assessed value. The HOA master policy and the individual condo policy are also handled separately.

• Separate APN: Each unit gets its own parcel number and tax bill.
• Same Prop 13 rules: Assessed value caps at 2% per year between sales.
• HOA dues: Pay the HOA separately. Dues cover common area upkeep, not property tax.
• Exemptions: Apply for the Homeowners’ Exemption in the unit owner’s name.
• Appeals: File a condo-specific appeal using the unit APN, not the building address.

Buyers should check both the property tax bill and the HOA budget before closing. A low HOA reserve can trigger a special assessment that lands on top of the regular tax bill.

Renters and Simi Valley Property Tax

Renters in Simi Valley do not pay property tax directly. The property tax bill goes to the property owner, who may pass the cost to renters through the monthly rent amount. Renters have no appeal rights on a tax bill. Renters can still take a few practical steps tied to the property tax status of the home.

• Rent indirectly: Higher property tax can push monthly rent higher in competitive markets.
• Check landlord status: Ask the landlord for proof that property tax is current before signing a lease.
• Report unsafe conditions: A property with unpaid taxes may also have maintenance issues that warrant a code complaint.
• Move-out protection: Unpaid property tax at move-out can delay a security refund until the title clears.
• Lease clauses: Read the lease for any tax pass-through language tied to property tax increases.

Direct all tax questions to the landlord or the property management company. The Ventura County Assessor will only discuss parcel details with the owner of record or a person with written authorization.

Simi Valley Real Estate Tax History Records

Property tax history for any Simi Valley parcel is available through the Assessor’s public search portal. The records go back to the original base year and show every transfer, change of value, and exemption change. The history is useful for buyers, sellers, and anyone tracking a long-held property.

• Open the Assessor parcel search at assessor.venturacounty.gov.
• Click the value history tab on the parcel detail page.
• Review the year-by-year assessed value and the reason for each change.
• Download the history as a PDF for use in a purchase offer or appeal packet.
• Use the data to check whether a recent sale qualifies for a Proposition 13 reset.

Sellers can pull the tax history before listing to confirm the value shown to buyers. Buyers should ask for the history as part of the due diligence period to spot any errors before close.
