How Property Tax Works

Shasta County, California operates under California's property tax system established by Proposition 13, which limits the base property tax rate to approximately 1% of assessed value. Property taxes in Shasta County fund essential local services including schools, fire protection, law enforcement, libraries, and county operations. The effective tax rate typically ranges from 1.0% to 1.3% of assessed value, depending on your specific location within the county.

Your actual property tax rate varies significantly based on the special taxing districts where your property is located. These districts may include school bonds, city bonds, community facilities districts (CFDs), and other local assessments that are added to the base 1% rate. Properties in incorporated cities often have different rates than unincorporated areas, and newer developments may carry additional Mello-Roos district assessments.

The Shasta County Assessor-Recorder determines assessed values, while the Tax Collector's office handles billing and collections. Under Proposition 13, your assessed value can only increase by a maximum of 2% annually until the property changes ownership or undergoes new construction, at which point it may be reassessed to current market value.

Supplemental Tax Bills

Supplemental taxes are additional property tax bills issued when your property's assessed value changes mid-year due to ownership transfer, new construction, or completion of improvements. These taxes cover the difference between your old and new assessed values for the remaining portion of the fiscal year.

What Triggers Supplemental Tax:

  • Property sale or transfer of ownership
  • Completion of new construction or major improvements
  • Changes in property use or zoning
  • Removal or addition of exemptions

Calculation Example: If you purchase a $500,000 home in January that was previously assessed at $300,000, you'll receive a supplemental bill for the increased assessed value ($200,000) for the remaining 5 months of the fiscal year. At a 1.2% tax rate, this would equal approximately $1,000 in supplemental taxes ($200,000 × 0.012 × 5/12 months).

Supplemental tax bills are mailed throughout the year with varying due dates, typically 30 days from the bill date. These are in addition to your regular annual property tax bill, and both must be paid by their respective due dates to avoid penalties.

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts, collecting 1/12 of your annual property tax bill with each monthly payment. Your lender pays the tax bills directly to Shasta County when due. Escrow accounts help ensure taxes are paid on time and spread the cost throughout the year.

How Escrow Works:

  • Lender estimates annual taxes and divides by 12
  • Monthly escrow payment included with mortgage payment
  • Lender maintains escrow account and pays tax bills on due dates
  • Annual escrow analysis adjusts payments based on actual tax bills

Escrow Account Management: Your lender will conduct an annual escrow analysis, typically adjusting your monthly payment if taxes increase or decrease. When property taxes change due to reassessment, bond measures, or new special districts, your escrow payment will be adjusted accordingly. You'll receive an escrow disclosure statement showing the calculation and any required changes to your monthly payment.

Always verify that your lender has paid your property taxes by checking with the Shasta County Tax Collector's office, especially after refinancing or changing loan servicers.

Frequently Asked Questions

Q: When are property taxes due in Shasta County for the current fiscal year? A: Property taxes are due in two installments: First installment due November 1, 2025, and second installment due February 1, 2026. The second installment becomes delinquent after April 10, 2026, at 5:00 p.m.

Q: What tax credits are available and do they require applications? A: The Homeowner's Exemption provides a $7,000 reduction in assessed value (saving ~$70-80 annually) but requires filing Form BOE-266. Disabled Veteran's Exemption and Senior Citizens' exemptions are also available but require separate applications. None of these credits are automatic.

Q: What is the Homeowner's Exemption and how do I apply? A: This credit reduces your assessed value by $7,000, typically saving $70-80 per year. You must file Form BOE-266 with the Shasta County Assessor-Recorder. This is a one-time application for owner-occupied residences, but you must reapply if you move to a new primary residence.

Q: How does Proposition 13 affect my property taxes? A: Prop 13 limits your base tax rate to approximately 1% and caps annual assessment increases at 2% until you sell or make major improvements. When you buy property, it's reassessed to current market value, then increases are limited to 2% per year.

Q: When and how can I appeal my property assessment? A: Assessment appeals must be filed between July 2 and November 30 annually. File with the Shasta County Assessment Appeals Board if you believe your assessed value exceeds market value. You can also request a Proposition 8 review if your property value has declined.

Q: What are the penalties for late property tax payments? A: The first installment becomes delinquent December 10 with a 10% penalty. The second installment becomes delinquent April 10 with a 10% penalty plus $20 cost. Additional penalties accrue monthly, and properties may eventually face tax lien sales.

Q: Can I pay my property taxes online? A: Yes, Shasta County offers online payment options through their official website. Check the Tax Collector's page for accepted payment methods, which typically include electronic checks and credit cards (fees may apply for credit card payments).

Q: What are special district taxes and Mello-Roos assessments? A: These are additional taxes for specific services or infrastructure improvements in designated areas. Mello-Roos districts (Community Facilities Districts) are common in newer developments and fund infrastructure like streets, sewers, and schools. These assessments appear as separate line items on your tax bill and vary by location.

Q: How do I know which special districts apply to my property? A: Your annual property tax bill lists all applicable districts and their rates. You can also contact the Shasta County Assessor-Recorder's office or check their online property search tool to identify the taxing districts for any specific property address.

Q: What happens with supplemental tax bills? A: Supplemental bills are mailed throughout the year with various due dates, typically 30 days from the bill date. These are separate from your annual tax bill and must be paid by their individual due dates. Both your regular and supplemental tax bills must be paid to avoid penalties.
