In Idaho, family members who have taken responsibility for providing care to their sick or disabled family members may be eligible for compensation for their duties.
In order to qualify, both you and your family member must meet a number of criteria, which can be found here: https://idahocaregiveralliance.com/for-the-caregiver/ After qualifying, getting HHA certification will still be required.
But if you are already spending much of your time caring for someone, this might be a viable option.
