Nevada County, CA Property Taxes Explained for Buyers
When you buy in Nevada County, the property is reassessed at the purchase price, and afterward its assessed value can rise by no more than 2% a year under Prop 13 unless you add new construction or it changes hands again. Expect a separate supplemental tax bill after closing that your lender may not pay, and file the homeowners’ exemption to reduce your assessed value by $7,000 if the home is your primary residence.
How it works
- Purchase sets a new base year value. Change of ownership or completed new construction triggers reassessment.
- The 2% cap. Base year values can increase at most 2% per year.
- Your tax bill. The Assessor sets value; the Tax Collector calculates the bill, which includes the general rate and any voter-approved local assessments for your area.
The supplemental bill
Because your purchase changes the assessed value mid-year, the county issues supplemental bills for the difference, prorated over the fiscal year (July 1 to June 30).
| If you close between | You receive |
|---|---|
| June 1 and December 31 | One supplemental bill |
| January 1 and May 31 | Two supplemental bills |
These bills go directly to you, separate from the regular annual bill. Don’t assume your lender’s impound account covers them.
The homeowners’ exemption
- $7,000 off assessed value, about $70 a year in savings.
- For your principal residence as of January 1.
- File form BOE-266 by February 15 for the full exemption; late filings through December 10 receive 80%.
Other programs to know
- Temporary decline-in-value review: if your home’s market value on January 1 is below its assessed value, you can ask for a review.
- Prop 19: base year transfers for qualifying homeowners 55+, disabled or disaster-affected.
- Disabled veterans’ exemption: for veterans rated 100% disabled or paid at 100% for unemployability.
