Appeal Your Lassen County Property Tax.

The Lassen County Assessor's office in Susanville values every property on California's January 1 lien date. When that assessed value overshoots the market, you have two tools: an informal Prop 8 decline in value review with the assessor, or a formal Assessment Appeals Board filing with the Clerk of the Board.

Lassen County Prop 8 Filing Steps

  1. Check if your property qualifies

    Run your address or APN through vulorean.com to see if your assessed value exceeds current market value as of January 1. If it does, you have a viable Prop 8 claim. You can also check your current assessed value at the Lassen ParcelQuest portal.

  2. Get your Vulorean valuation report

    The report produces a market value opinion as of the January 1 lien date and includes comparable sales. Choose DIY (you file using the report) or Concierge (Vulorean handles everything from here).

  3. Contact the Assessor to file your informal review

    Lassen has no dedicated online Prop 8 form — all reviews are initiated by contacting the Assessor directly.

    DIY Call or email the Assessor and submit your Vulorean report as supporting documentation.
    Concierge Your Vulorean rep contacts the Assessor and handles the submission on your behalf.

  4. Await assessor response

    DIY If approved, your reduced value is reflected on your tax bill and reviewed annually.
    Concierge Your Vulorean rep monitors the response and keeps you informed.

  5. Formal appeal if denied

    DIY File an Application for Changed Assessment (BOE-305-AH) with the Lassen County Clerk of the Board between July 2 and November 30. File in parallel with step 3 to protect your rights.
    Concierge Your Vulorean rep handles the appeal filing on your behalf.

Lassen County reminder: California's Prop 13 caps annual taxable value growth at 2%, so a successful appeal keeps paying dividends every year your market value sits below the Prop 13 base. Prop 8 is the complement. It lets you capture temporary market dips. Both paths run through the Lassen County Assessor in Susanville.

Lassen County Property Tax FAQ

When does Lassen County mail assessment notices?

California counties, including Lassen, typically mail notices in June or July. Your window to file BOE-305-AH opens July 2 and closes either September 15 or November 30 depending on the county's Clerk of the Board schedule. Confirm with the Lassen Clerk's office.

Do I have to use an attorney?

No. The California Assessment Appeals Board is designed for pro se homeowners. Filing BOE-305-AH is a two page form and hearings are informal. Most Lassen County homeowners file and represent themselves.

Will my Lassen County taxes go up if I appeal?

No. California appeal outcomes at the Assessment Appeals Board are strictly reductions or no change. Prop 13 caps assessed value growth at 2% per year regardless.

Is Prop 8 the same as Prop 13?

No. Prop 13 is the base year rule that caps annual assessment growth. Prop 8 is the companion rule that lets the assessor (or you) temporarily drop your value below the Prop 13 base when the market falls. When the market recovers, your value can rise back up to the Prop 13 cap, but not above it.
