How Property Tax Works

Calaveras County property taxes are the primary funding source for essential local services including public schools, fire protection, law enforcement, libraries, and county infrastructure. Property owners in Calaveras County are subject to California's Proposition 13 tax structure, which establishes a base tax rate of 1% of assessed value plus additional voter-approved assessments for bonds and special districts.

The effective property tax rate in Calaveras County typically ranges from 1.0% to 1.3% of assessed value, depending on your specific location within the county. Actual rates vary significantly by area due to special taxing districts such as school bonds, fire districts, library districts, and Community Facilities Districts (CFDs). Properties in incorporated areas may have additional city-specific assessments, while rural properties may be subject to different special district combinations.

Property assessments in Calaveras County are capped at 2% annual increases under Proposition 13, providing predictable tax growth for existing homeowners. New purchases are assessed at current market value, and the assessment grows from that baseline at the capped rate.

Section 4

Supplemental Tax Bills

Supplemental property taxes are additional tax bills issued when there is a change in ownership or completion of new construction that increases a property's assessed value during the tax year. These taxes cover the difference between the old and new assessed values for the remaining months in the current fiscal year (July 1 - June 30).

Supplemental taxes are calculated by taking the difference between the new assessed value and the previous assessed value, multiplying by your area's tax rate, then prorating for the remaining months in the fiscal year. For example, if you purchase a $500,000 home in January that was previously assessed at $300,000, you would owe supplemental taxes on the $200,000 increase for the remaining 6 months of the fiscal year.

Supplemental tax bills are mailed separately from regular annual tax bills and have different due dates. These bills typically arrive 4-8 weeks after the triggering event and must be paid within 30 days of the delinquency date printed on the bill. Contact the Calaveras County Treasurer-Tax Collector at (209) 754-6375 for specific supplemental tax inquiries.

Escrow & Property Taxes

Most mortgage lenders in Calaveras County require borrowers to maintain an escrow account for property taxes. Your lender collects 1/12 of your estimated annual property tax bill with each monthly mortgage payment, then pays the county directly when taxes are due.

Property taxes in Calaveras County are payable in two installments: the first installment covers July through December and is due November 1st (delinquent December 10th), while the second installment covers January through June and is due April 1st (delinquent April 10th). Your lender will typically pay each installment by the due date to avoid penalties.

Lenders conduct annual escrow analyses to ensure adequate funds are collected. If your tax bill increases due to reassessment or new voter-approved measures, your monthly escrow payment may increase. You can verify escrow payments by checking your annual tax bill or contacting the Calaveras County Treasurer-Tax Collector at (209) 754-6375. Property owners remain ultimately responsible for ensuring taxes are paid even when using escrow services.

Frequently Asked Questions

Q: When are property taxes due in Calaveras County for fiscal year 2024-2025? A: Property taxes are due in two installments: first installment due November 1, 2024 (delinquent December 10, 2024), and second installment due April 1, 2025 (delinquent April 10, 2025).

Q: What property tax credits are available and do they require applications? A: The primary credit is the Homeowners' Exemption, which reduces assessed value by $7,000 (saving $70-84 annually). This requires filing form BOE-266 with the Assessor's Office by February 15th. Additional credits may include Veterans' Exemption and Disabled Veterans' Exemption, all requiring separate applications.

Q: How does the Homestead exemption work in California? A: California doesn't have a traditional "homestead exemption." The Homeowners' Exemption reduces your home's assessed value by $7,000. More importantly, Proposition 13 caps annual assessment increases at 2% for all properties, providing ongoing tax protection that requires no application.

Q: When does the county reassess my property? A: Properties are reassessed to current market value upon change of ownership or completion of new construction. Otherwise, assessed values can only increase by a maximum of 2% annually under Proposition 13, regardless of market value changes.

Q: How do I appeal my property assessment? A: File an Application for Changed Assessment (BOE-305-AH) with the Calaveras County Assessment Appeals Board between July 2nd and November 30th. Contact the Clerk of the Board at (209) 754-6370 for forms and procedures.

Q: What are the penalties for late property tax payments? A: A 10% penalty is added to delinquent first installments after December 10th. Second installments become delinquent April 10th with 10% penalty plus 1.5% monthly interest. Properties with delinquent taxes for 5 years may be sold at tax auction.

Q: Can I pay my property taxes online? A: Yes, online payments are accepted through the Calaveras County Treasurer-Tax Collector website at www.co.calaveras.ca.us. Payments can be made by electronic check or credit card (convenience fees apply for credit cards).

Q: What are Mello-Roos taxes and Community Facilities District (CFD) fees? A: These are special assessments in newer developments to pay for infrastructure like roads, schools, and utilities. CFD rates vary by development and appear as separate line items on your tax bill. Contact the county for specific CFD information for your property.

Q: Why did I receive a supplemental tax bill? A: Supplemental bills are issued when property changes ownership or new construction is completed, covering the tax difference for the remaining months of the current fiscal year. These are separate from your regular annual tax bill and have different due dates.

Q: How can I get a copy of my current tax bill? A: Current and prior year tax bills are available online through the Calaveras County Treasurer-Tax Collector website using your Assessor's Parcel Number (APN), or by calling (209) 754-6375.
