You’re correct! Some types of insurance are tax deductible. Home warranty insurance can be tax deductible if you own a business.
Insurance isn’t tax deductible unless it’s used for business purposes. For example, if you operate your business out of your home, you typically can deduct your home insurance from your taxes. The same would go for home warranty insurance.
That said, insurance and taxes are two specialized industries. To avoid any errors with your taxes, you’ll want to speak with your accountant or tax specialist to determine what you can and can’t deduct.
