Publication 502 permits qualifying costs of acquiring, training and maintaining a guide dog or other service animal assisting a person with the disabilities described in the guidance. It gives food, grooming and veterinary care as examples of maintenance needed for the animal to perform its duties.
That section does not expressly name a pet-insurance premium. Do not turn permission for veterinary maintenance into an automatic premium deduction. Ask a tax professional whether the specific premium qualifies in your facts, what documentation supports the animal’s role, and how any personal or nonqualifying component should be treated.
An emotional-support description, an online certificate or an insurer’s willingness to cover the animal does not by itself answer the federal tax question. Use the IRS criteria and your actual facts rather than relying on the animal’s label.
