The Imperial County Assessor's office in El Centro values every property on California's January 1 lien date. When that assessed value overshoots the market, file both: an informal Prop 8 decline in value review with the assessor (fast, often resolves without a hearing) and a formal Assessment Appeals Board filing with the Clerk of the Board (protects your right to a hearing).

Imperial 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 Imperial County Assessor in El Centro.
When You Probably Qualify for a Imperial County Reduction
- Your current assessed value is above recent sales of comparable homes in Imperial County
- You bought in Imperial County in the last 12 months below the county's assessed value
- Your Imperial Assessor parcel record has errors, wrong square footage, added features that don't exist, or incorrect grade

- Your neighborhood's market softened but the Imperial Assessor hasn't adjusted

When does Imperial County mail assessment notices?
California counties, including Imperial, typically mail notices in June or July. Your window to file BOE-305-AH opens July 2 and closes November 30 in Imperial County, per the California BOE county filing periods list. Confirm current-year dates with the Imperial 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 Imperial County homeowners file and represent themselves.
Will my Imperial 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.
