Declaration of Domicile

Requirements Summary

  • If you have utility service in your name at only one occupied location, you are not required to submit a Declaration of Domicile form.
  • If you have more than one occupied property with utility service in your name, you are required to submit a completed Declaration of Domicile form.

Beginning January 1, 2023, Kentucky’s 2022 tax reform legislation becomes effective and at such date and going forward will require customers applying for new residential utility services to complete and return to their utility company a Declaration of Domicile1 form (51A380). The Declaration of Domicile form must be completed and signed by the occupant of the residence and this individual can only have one Declaration of Domicile on file with the utility, in this case OMU. If the residential property does not have a Declaration of Domicile, then the residence will not be exempt from state sales tax on applicable utility services.

Multiple Locations in a Single Name

The legislation also applies to customers that currently have more than one residential service location on an account in the customer’s name. If you fall within this category and your properties are occupied, then you must have the qualifying occupant complete and sign the Declaration of Domicile form (51A380) for each residential service location where you are the utility account holder and you must file any forms with OMU by December 31, 2022 to avoid being assessed state sales tax.

Master Meter/Single Meter Serves Multiple Dwellings

If you are the account holder of a residential multi-unit dwelling that is served by a single meter, this service is eligible for the sales tax exemption only if the meter does not also serve common areas. To qualify for the sales tax exemption you 1) must complete and sign the Multi-Unit Declaration of Domicile form (51A381); 2) have each unit’s qualifying occupant compete and sign a Declaration of Domicile form (51A380); and 3) all of the forms must be filed with OMU by December 31, 2022. Any Multi-Unit Declaration that does not include a Declaration of Domicile form from ALL dwelling units served by the master meter will not qualify for the sales tax exemption.

Below are the two Declaration of Domicile forms.
