Plumas County Property Tax
The average property-tax rate in Plumas County is about 1.1% of assessed value (Board of Equalization county average, 2024-25) — the 1% Proposition 13 base levy plus each area's voter-approved debt. That's close to the statewide average of about 1.11%, making it the 35th-highest of California's 58 counties (the 24th-lowest). On a $500,000 assessed value that's roughly $5,475 a year.

How Plumas County property tax is calculated
California taxes property under Proposition 13: your assessed value is generally set when you buy, then rises no more than 2% a year until the property changes hands or is newly built. The annual bill is that assessed value times the ad-valorem rate — the 1% base plus voter-approved bonds — which is why Plumas County's average works out to about 1.1%. Because the bonds differ by Tax Rate Area, two homes in the same county can pay slightly different rates.
What changed in Plumas County's rates for 2026-27
Comparing the county's 2026-27 rate book with 2025-26, Tax Rate Area by Tax Rate Area, the parcel-weighted median ad-valorem rate fell from 1.0423% to 1.0405% (−0.0018 points). Rates rose for none of the county's 25,481 parcels in rated areas; they fell for 95.7%, with 4.3% unchanged. The 1% Proposition 13 base never moves; what moved is the voter-approved debt on top of it, which each agency recalculates every year from the bonds it must repay and the assessed value that repays them.
- Plumas USD Bond Measure A: 0.0119% → 0.0110% (−0.0010), on about 24,381 parcels — school district facilities bonds.
- Plumas USD Bond Measure B: 0.0303% → 0.0295% (−0.0008), on about 24,381 parcels — school district facilities bonds.
- Plumas District Hospital Bond 2008: 0.0345% → 0.0327% (−0.0017), on about 4,681 parcels — a local hospital or health-care district bond.

What's on a property tax bill
Ad-valorem tax (1% base + voter-approved debt) · Mello-Roos special taxes, where a parcel is in a Community Facilities District (how long they last) · fixed direct assessments (lighting, sewer, etc.). Only the first is value-based; the 1.1% rate covers that part.
Learn the rules behind the rate: how California property tax is calculated, Proposition 13, Mello-Roos, and what triggers a reassessment.

Plumas County property tax by the numbers
How much is property tax in Plumas County? For an existing owner the average single-family home is assessed near $326,475 (2024, the latest year the county reported to the BOE), so at the county's 1.095% average rate (Board of Equalization county average, 2024-25) the implied bill is about $3,575 a year (a mean across all existing owners, not a median). A new buyer is taxed on the purchase price instead — use the calculator above. The figures below are the county-level activity behind that rate.
Sources: California State Board of Equalization (assessors' workload tables, Table E1 single-family values, property-tax allocation), the California Debt and Investment Advisory Commission (Mello-Roos roster), the California FAIR Plan Association (policies in force by county) and CAL FIRE / OSFM fire hazard severity zones weighted by 2020 housing units. County aggregates only, no parcel or owner identities; counts are filings processed and can lag the event year. Plumas County's latest return to the BOE left some tables blank, so the assessed value, transfers, Prop 8, appeals cards show the most recent year it reported (the year is on each card). Verify with the Plumas County Assessor before relying on them.
Due dates & where to pay
Plumas County property taxes are paid in two installments: first due November 1 (delinquent after December 10) and second due February 1 (delinquent after April 10). A 10% penalty applies after each delinquency date, and a bill still unpaid on July 1 becomes tax-defaulted; after five years in default the county may sell it at auction (see the California tax sale calendar). Boats, aircraft and business equipment are billed separately on the unsecured roll, due in one payment by August 31. Pay or look up a parcel through the Plumas County Treasurer-Tax Collector. Portal links, fees and missing-bill numbers for every county are on one look-up-and-pay page.
These deadlines are set by California state law (Revenue & Taxation Code §§ 2605, 2606, 2617 and 2701) and are the same in every county — this is general education, not a county-by-county check. If a delinquency date falls on a weekend or legal holiday, it moves to the next business day. Always confirm the exact dates and amounts on your own tax bill and your county tax collector's website. See the full California property tax due-date calendar for the dated 2026–27 schedule, penalties, and when bills are mailed.
Ways to lower your bill
- The $7,000 Homeowners' Exemption for owner-occupants (~$70/yr) — not the same as the homestead exemption, which protects home equity from creditors and changes no tax.
- Senior programs — Property Tax Postponement (62+, income-qualified; the state pays the bill at 5% simple interest) and a Proposition 19 base-year transfer (55+).
- A Proposition 8 decline-in-value review if the market drops below your assessed value.
- Appealing your assessment if it looks too high — the regular filing window in Plumas County runs July 2 to November 30 (2026); only the assessed value can be appealed, not the rate or the flat charges.
Selling in Plumas County: the transfer tax
A sale also pays a one-time documentary transfer tax of $1.10 per $1,000 of the price (net of any loan the buyer takes over) to the county (Revenue and Taxation Code §11911), $1,100 on a $1,000,000 sale. We have found no city transfer tax in Plumas County (the 27 California cities whose codes we have read are mostly in the Bay Area and Los Angeles County), so the county rate is normally the whole tax. Estimate it for any sale with the California transfer tax calculator; the documentary transfer tax guide covers who pays and the exemptions.
Plumas County assessed value by city
The size of the property-tax base in Plumas County's one incorporated city: the total assessed value of all property inside the city limits on the 2025 roll, how fast it is growing, and its share of the county's $6.52 billion total. About 97.2% of the county's assessed value lies outside any city, in unincorporated areas.
| City | Assessed value (2025 roll) | 1-year change | Since 2013 | Share of county | Per resident |
|---|---|---|---|---|---|
| Portola | $185 million | -0.2% | +66.0% | 2.8% | $91k |
Assessed value = the whole city's roll (homes, businesses, land and state-assessed utility property together) as reported by the Board of Equalization (Table 11), a Proposition 13 basis — not a typical home value, a tax rate or a bill. Growth reflects reassessment on sale, new construction, the annual inflation factor (capped at 2%), Proposition 8 decline-in-value cuts and their restoration, disaster losses, and any change in city boundaries. Share of county uses the county's total assessed value (Table 10); the two tables' bases differ slightly. Per resident divides the city's roll by its July 1, 2025 Census population estimate (Population Estimates Program, Vintage 2025); a high figure means a lot of commercial, industrial or second-home value per inhabitant, not a high tax bill. Plumas County does not publish its parcel roll in bulk, so the per-home figure on this page is the Board of Equalization's average single-family assessment (the “Typical bill” line above, about $3,575 a year) rather than a roll median — use the county rate and the calculator above for your own estimate.
