Change in Ownership Exclusions

  • Parent/Child and Grandparent/Grandchild Transfer Exclusion
    • Effective November 6, 1986, transfers between parents and their children (in either direction) of a principle residence and up to $1 million (taxable value) of other property may be excluded from change in ownership reassessment, providing a claim is filed and certain requirements are met. It also applies to transfers between a trust and a parent or child. It does not apply to transfers to and from partnerships, corporations, or other legal entities. To download the Claim for Reassessment Exclusion for Transfer between Parent and Child, click here (pdf) or go to Forms.

      A similar exclusion was enacted for transfers of property from grandparents to grandchildren (but not vice versa) occurring on or after March 27, 1996, under certain limiting conditions. Among those limiting conditions is the requirement that both parents of the grandchild (or grandchildren) who qualify as the children of the grandparents must be deceased as of the date of transfer.

These conditions include: the sole two cotenants together must own 100% interest in the property; the transfer results in the surviving cotenant owning 100% of the property; the two cotenants owned and continuously resided in the property for the one year period as their principal residence preceding the date of transfer. A Preliminary Change of Ownership form or theChange in Ownership Statement must be filed and the surviving cotenant must sign an affidavit affirming residency.
