Sacramento County property tax due dates and deadlines for 2026
The bill due dates, the two appeal windows, and what to do if you're late — all specific to Sacramento County.
Sacramento County has two property tax appeal deadlines, because it has two separate processes. The free informal review with the Sacramento County Office of the Assessor: July 1 – December 31. The formal appeal with the Sacramento County Assessment Appeals Board: July 2 – November 30, with a $30 filing fee. Both measure your home's value as of the same date: January 1, the lien date.
Everything on this page is specific to Sacramento County. For how the deadlines work statewide — and why some counties' formal deadline is September 15 while others run to November 30 — see the California-wide deadlines guide. For the full step-by-step appeal process here, see the Sacramento County appeal guide.

The value on your bill
Yes — you can still appeal the value on your 2026–27 bill.
Most of your bill is your assessed value times the tax rate, so the assessed value printed on it is the number an appeal can lower. Start with the free informal review: the Sacramento County Office of the Assessor takes requests until December 31. The formal appeal to the Sacramento County Assessment Appeals Board stays open until November 30 (a $30 filing fee).

| Nov 1 – Dec 10, 2026 | First installment | First property tax installment due Nov 1, late after 5 p.m. December 10, 2026. Pay it even if your appeal is pending — you get a refund with interest if you win. |

Check my propertyWhat if I missed a deadline?
Missed the informal window? If the formal window (July 2 – November 30) is still open, file the formal appeal — same evidence, and your appeal rights are preserved with a binding decision at the end.
Missed both? For a regular decline-in-value case, you wait for the next January 1 lien date and file in next year's windows. The deadlines aren't extendable, but nothing stops you from preparing early — the evidence rules reward sales close to the lien date, so the strongest comps for next year's appeal close between this fall and next March.
Got a supplemental or escape assessment notice? Those carry their own appeal window — generally 60 days from the date on the notice — independent of the windows above.

Common questions
When is the Sacramento County property tax bill due?
The 2026–27 bill comes in two installments. The first is due November 1 and is late after 5 p.m. on Thursday, December 10, 2026; the second is due February 1 and is late after 5 p.m. on Monday, April 12, 2027. A late installment adds a 10% penalty. Pay on time even if you're appealing — if you win, the county refunds the difference with interest.
When will I get my 2026–27 Sacramento County property tax bill?
By November 1, 2026 — state law has every California county send its secured property tax bills by then. If yours hasn't arrived, you still owe on time, so don't wait for the mail: look it up online with the Sacramento County Tax Collector.
When is the deadline to appeal property taxes in Sacramento County?
There are two separate deadlines. The free informal review with the Sacramento County Office of the Assessor: July 1 – December 31. The formal appeal with the Sacramento County Assessment Appeals Board: July 2 – November 30. They are independent processes — if the informal review hasn't come back before the formal window closes, file the formal application as a backstop so you don't lose your appeal rights for the year.
Does it cost anything to appeal in Sacramento County?
The informal decline-in-value review is free. The formal appeal to the Sacramento County Assessment Appeals Board has a $30 filing fee. In both cases the evidence is the same: recent comparable sales showing your home's market value on January 1 was below your assessed value.
What form do I need for a Sacramento County property tax appeal?
For the informal review, Sacramento County uses the Decline-in-Market Value Request for Assessor Review (Prop 8) form, submitted to the Sacramento County Office of the Assessor. For the formal appeal, you file BOE-305-AH with the Clerk of the Board during the July 2 – November 30 window.
What if I miss the Sacramento County appeal deadline?
If you miss the informal window but the formal window (July 2 – November 30) is still open, file the formal appeal. If both have closed, you generally have to wait for the next January 1 lien date and file in next year's windows — current-year deadlines aren't extendable for a regular decline-in-value case. Exceptions exist for supplemental and escape assessments, which carry their own clock: generally 60 days from the date on the notice.
