LA County Sales Tax Change Takes Effect Oct. 1, 2026

The scheduled change

A Los Angeles County sales tax rate change is set to take effect Thursday, Oct. 1, 2026. The City of West Hollywood has posted notice of the effective date.

The notice identifies the change as a countywide sales tax matter and places its start date on Oct. 1, 2026. It does not state the current rate, the new rate or the size of the change.

What the notice establishes

The clearest point is the timing: the change is scheduled to begin on Oct. 1, 2026. That date is a Thursday.

The notice does not provide additional details about the tax rate, the specific transactions affected or how the change will be administered. Those details are important for anyone trying to calculate the tax on a purchase, but they are not included in the notice identified here.

What to watch

Residents, businesses and local officials can watch for additional public information before the effective date. Future notices may explain the rate, the transactions covered and the steps needed to apply the change.

For now, the City of West Hollywood’s notice establishes the scheduled effective date without stating the amount of the new rate.
