Getting veterans benefits for paid family caregivers is not an easy task. There must be a caregiver contract in place and services for care must be initiated and thoroughly documented before application can be made. In addition, state and federal tax requirements must be met.
Go to your Veterans local VA office and ask to speak to the Home Caregiver Coordinator, they will give you everything you need to get started. Its a very painless and easy process usually completed within 45 days.
