Transfer Your Tax Base
Under specific conditions it is possible to transfer your protected Proposition 13 tax base (specifically, the factored base year value) from an existing property to a replacement property, thus avoiding reappraisal of the new property at fair market value.
Base year value transfers are available for:
- Qualified persons aged 55 and older or severely disabled persons of any age.
- Persons whose property has been subject to an eminent domain taking or other governmental acquisition.
- Environmentally contaminated property.
