Planning your Sherman Oaks budget and not sure what to set aside for property taxes? You are not alone. LA County’s rules are clear once you see how assessments, due dates, and escrow impounds fit together. In this guide, you will learn the essentials of Proposition 13, how supplemental bills work after a sale, when taxes are due, and what to expect in escrow, with simple Sherman Oaks examples to plug into your plans. Let’s dive in.
LA County tax basics
Prop 13 in plain English
When you buy a home, LA County sets a new assessed value based on market value at the time of purchase. After that, your assessed value can increase by at most 2% per year until there is a new sale or new construction. The base tax rate is 1% of assessed value, and voter‑approved bonds or parcel charges are added to that, so every parcel’s combined rate is slightly different. For a plain‑language overview, see the California Legislative Analyst’s Office explanation of Proposition 13 at the LAO website.
Beyond the 1% rate
In Sherman Oaks, the effective rate often lands above 1% once you include bonds and special assessments. That is why two similar homes can have slightly different total tax amounts. Always check the parcel’s current bill to see the combined rate and line‑item charges on the LA County Treasurer and Tax Collector site.
Key dates to remember
LA County operates on a July 1 to June 30 fiscal year. Regular secured bills are typically mailed around October 1. The first installment is due November 1 and becomes delinquent after December 10. The second installment is due February 1 and becomes delinquent after April 10. Confirm current year dates and payment options on the LA County Treasurer and Tax Collector.
When values reset and why
Reassessment triggers
A change in ownership or new construction triggers reassessment to current market value. That updated value becomes your new base for future years, subject to the 2% annual cap. You can review how reassessments work and find Prop 19 updates on the LA County Assessor.
Prop 19 highlights
Prop 19 changed two areas many owners ask about. It tightened the rules for parent‑child transfers and expanded base‑year value portability for homeowners age 55+, those with severe disabilities, and some disaster victims. For eligibility details and forms, review the Assessor’s guidance on the LA County Assessor site and consult a tax adviser for your situation.
Supplemental bills after a sale
A sale usually generates a supplemental assessment that captures the difference between the prior assessed value and the new assessed value. The supplemental bill is prorated for only the portion of the fiscal year remaining after your closing date. It is a separate bill with its own due date and can arrive before your next regular bill. For timing and how to pay, see supplemental billing information at the Treasurer and Tax Collector.
Escrow, impounds, and proration
Lender impounds 101
If you finance your purchase, your lender may require an escrow (impound) account for property taxes and homeowners insurance. You will pay one‑twelfth of the annual taxes each month, and the lender will also collect an initial deposit plus a small cushion. This setup helps ensure funds are available when installments come due.
Who pays what at closing
In California, taxes are typically prorated by day. Sellers usually pay up to the day before closing, and buyers pay from the day of closing forward, based on a 365‑day year. If you close between installments, escrow credits and charges are calculated so each party covers only their share for that period. Your final settlement statement will show these prorations.
Sherman Oaks examples
The figures below use an assumed combined effective tax rate of 1.16% for quick estimates. Actual rates vary by parcel, so verify your property’s bill on the county site.
Annual tax and monthly impound estimate:
- Condo or townhome at $900,000: annual ≈ $10,440, monthly impound ≈ $870.
- Single‑family at $1,500,000: annual ≈ $17,400, monthly ≈ $1,450.
- Higher‑end at $2,500,000: annual ≈ $29,000, monthly ≈ $2,417.
Mid‑March closing proration (example):
- Purchase price $1,500,000. Second installment (Jan–Jun) ≈ $8,700.
- Closing on March 15: seller days Jan 1–Mar 14 = 73; buyer days Mar 15–Jun 30 = 108.
- Seller share ≈ $3,507.70; buyer share ≈ $5,192.30.
Supplemental bill after sale (example):
- Prior assessed value $800,000. New value $1,500,000. Increase = $700,000.
- Added annual tax at 1.16% ≈ $8,120.
- If closing on May 1, the supplemental covers about 61 days to June 30, or roughly $1,357.
Budgeting tips to avoid surprises
- Verify your exact combined rate and any parcel charges on the Treasurer and Tax Collector.
- Review assessed value history and potential exclusions on the LA County Assessor.
- If using a mortgage, ask your lender for the initial impound deposit and monthly escrow estimate.
- If you are selling, request your payoff statement early. This shows any escrow impound surplus or shortage tied to your loan.
- Expect a supplemental bill after closing if your home was reassessed, and set aside funds so the separate due date does not catch you off guard.
Quick checklists
For sellers
- Gather your latest secured tax bill and any recent supplemental notices for escrow.
- Order a loan payoff statement that includes your impound balance.
- Decide in the purchase contract how potential supplemental bills will be handled.
For buyers
- Ask escrow to share the tax proration worksheet and confirm the day‑of‑closing convention.
- Confirm whether your lender requires impounds and what the startup deposit will be.
- Use the county parcel tools to check assessed value history and parcel charges on the Assessor and Treasurer and Tax Collector.
For both parties
- Keep signed escrow instructions and the final closing statement. They are helpful if questions arise later about prorations or supplemental bills.
- Put the November 1, December 10, February 1, and April 10 milestones on your calendar and verify current year dates at the Treasurer and Tax Collector.
