Property taxes in Elk Grove are billed and collected by Sacramento County, not by the city. The base rate is 1% of your home’s assessed value under Proposition 13, and your actual bill is that 1% plus voter-approved school bonds, any Mello-Roos community facilities charges tied to your neighborhood, and direct levies for services like mosquito abatement. Payments are due in two installments each year, with firm December and April deadlines and a 10% penalty the moment you miss one.
What You Actually Pay
Your tax bill is layered, and the layers are why two homes on different streets with identical assessed values can owe very different amounts.
- The 1% general levy. On a home assessed at $500,000, this portion is $5,000.
- Voter-approved bonds. School district bonds and other voter-approved debt sit on top of the base rate. Elk Grove Unified School District’s Measure N, approved in November 2024, authorized $542 million in bonds with an estimated levy of about $34 per $100,000 of assessed value. Several bonds can be active at once, each with its own line.1Ballotpedia. Elk Grove Unified School District, California, Measure N, School Improvements Bond Measure
- Mello-Roos. Many Elk Grove neighborhoods, especially newer developments, sit inside Community Facilities Districts that fund parks, lighting, landscaping, and infrastructure. These charges aren’t tied to assessed value; they’re set by parcel size or land use and can run from a few hundred to several thousand dollars a year.2Southern California Association of Governments. Mello-Roos Community Facilities District
- Direct levies and special assessments. Fixed-dollar charges for infrastructure assessment districts, mosquito abatement, and similar local services appear as separate line items and have their own, faster foreclosure rules if left unpaid.3Sacramento County Department of Finance. Secured Taxes
The practical result: most Elk Grove homeowners pay noticeably more than a flat 1% of their assessed value once everything is added together.
How Your Home Is Assessed
The Sacramento County Assessor sets the taxable value under Proposition 13. The rate is capped at 1% of full cash value at the time of purchase, and once you own the home, the assessed value can rise by no more than 2% per year regardless of what the market does.4California State Board of Equalization. California Property Tax – An Overview A home bought for $550,000 in 2024 can be assessed at no more than $561,000 by 2026, even if comparable sales suggest it’s worth $620,000.
Full reassessment to current market value happens only when the property changes ownership or new construction is completed.4California State Board of Equalization. California Property Tax – An Overview Add a room and only the new construction gets reassessed; the rest of the home keeps its existing value with the 2% cap intact.
If values in your area drop below your factored base year value, you can request a Proposition 8 reduction, and the Assessor must enroll the lower figure that year.5Office of the Assessor, County of Santa Clara. Temporary Decline in Market Value (Proposition 8) The reduction is temporary. As the market recovers, your assessed value climbs with it until it catches back up to the factored base year value. Sacramento County mails a Notification of Assessed Value at the end of June each year, which is your chance to compare the Assessor’s number to what you think the home is worth.
Inherited Homes
If you inherit a family home from a parent, the property is reassessed to current market value unless you move in and claim it as your primary residence within one year of the transfer. You have to file form BOE-19-P with the Sacramento County Assessor and apply for the homeowners’ exemption within that same year.6California State Board of Equalization. Proposition 19 Fact Sheet Intergenerational Transfer Exclusion Even then, the exclusion is capped at the parent’s factored base year value plus an adjusted allowance of $1,044,586 for transfers between February 16, 2025, and February 15, 2027.7California State Board of Equalization. Proposition 19 Anything above that combined figure gets added to taxable value. Miss the one-year deadline and the whole property is reassessed at full market value.
The Supplemental Bill After You Buy
Buying a home triggers a supplemental tax bill that arrives separately from the regular annual bill. The Assessor recalculates the property’s value based on your purchase price, and the difference between the prior owner’s assessed value and yours gets prorated for the months remaining in the fiscal year.8California State Board of Equalization. Supplemental Assessment
Close escrow between June 1 and December 31 and you’ll get one supplemental bill covering the rest of the current fiscal year ending June 30. Close between January 1 and May 31 and you’ll get two: one for the balance of the current fiscal year and another for the full year that follows.8California State Board of Equalization. Supplemental Assessment These bills arrive on their own timeline with their own delinquency dates. Watch your mail after closing.

What Late Payment Costs
Miss either installment deadline and you owe a 10% penalty on the unpaid amount plus a $15 cost.3Sacramento County Department of Finance. Secured Taxes On a $4,000 installment, that’s $415. The penalty is the same whether you’re one day late or three months late.
Keep ignoring the bill and consequences escalate. After five or more years of delinquency, the property becomes tax-defaulted and subject to the Tax Collector’s power of sale, meaning it can be auctioned off to recover unpaid taxes.12Sacramento County Department of Finance.

The Homeowners’ Exemption
If you own and occupy your Elk Grove home as your primary residence on January 1 (the lien date), you qualify for California’s homeowners’ exemption. It knocks $7,000 off your assessed value, saving about $70 a year on the 1% general levy.13California Legislative Information. California Revenue and Taxation Code 218 Small money, but it’s a one-time filing that stays in effect as long as you live there.
File with the Sacramento County Assessor by 5 p.m. on February 15.14California Legislative Information. California Revenue and Taxation Code 255 Miss it and you can still file late for 80% of the exemption, within a later cutoff.15Legal Information Institute. Cal. Code Regs. Tit. 18, 135.5 – Homeowners Property Tax Exemption If you later move out or convert the home to a rental, you have to notify the Assessor. Failing to report a change of residency after a written request can bring a penalty of $100 or 10% of the taxes on the new assessment, whichever is greater, up to $2,500.
Relief for Seniors, Disabled Homeowners, and Low-Income Owners
If you’re 55 or older or severely disabled, Proposition 19 lets you sell your current home and transfer its lower assessed value to a replacement home anywhere in California, up to three times. The replacement must be purchased or newly built within two years of selling the original. If the new home’s market value is equal to or less than the old home’s, the base year value transfers across straight. “Equal or lesser” gets a small cushion: 105% of the original’s market value if you buy within the first year after the sale, 110% in the second year.7California State Board of Equalization. Proposition 19 Buy a pricier home and the amount above the threshold gets added to your transferred base year value. For a longtime owner whose assessed value sits far below market, this can mean thousands in annual tax savings.
California’s State Controller also runs a Property Tax Postponement program for seniors, blind residents, and people with disabilities. If annual household income is $55,181 or less and you hold at least 40% equity in your primary residence, you can defer payments until you sell, move out, or pass away.16State Controller of California. Property Tax Postponement The deferred amount becomes a lien on the property and accrues interest, so this is a loan, not forgiveness. The program reopens each year; the 2025–26 filing period closed February 10, 2026.
Appealing Your Assessment
If you think the Assessor’s value is too high, start with an informal call to the real property appraisal staff at (916) 875-0700.17Sacramento County Assessor. Assessment Appeals Many disputes get resolved there. If not, file a formal appeal with the Sacramento County Assessment Appeals Board.
The annual filing window for regular assessments runs July 2 through November 30. For supplemental assessments triggered by a purchase or new construction, you have 60 days from the date on the notice or bill.18Clerk of the Board of Supervisors, Sacramento County. Property Assessment Appeals Sacramento County requires a paper application; there is no online filing. The signed form goes to the Assessment Appeals Board at 700 H Street, Suite 2450, Sacramento, with a $30 nonrefundable processing fee.19Clerk of the Board of Supervisors, Sacramento County. Assessment Appeals
Comparable sales, independent appraisals, and photos of condition problems are the strongest evidence. If the Board lowers your value, the county refunds any excess tax you already paid. Filing an appeal does not pause your payment obligation; skip the installment while you wait for a hearing and you’ll owe penalties and interest no matter how the appeal turns out. Missing the filing deadline ends your ability to challenge that year’s assessment, with no extensions. The Notification of Assessed Value arrives at the end of June, so if the number looks wrong, you have a narrow window before July 2 to get ready.
